Command Reference

This appendix discusses all aspects of the command set for the Catalyst 1200 series Switch. A list of top-level commands is provided in Table C-1.

Command Line Processing

The user interface for the admin. port on the switch is a basic command line interpreter similar to that of the UNIX C shell. Command-line editing is provided, including history substitution and aliasing. If you make a mistake while entering a command, use the Delete or Backspace key to erase the mistake and then reenter the command.

History Substitution Buffer

Commands entered during a terminal session are stored in a history substitution buffer. Commands in this buffer can be repeated or edited in a style similar to the UNIX C shell. The buffer stores the last eight commands entered during a terminal session. (See the section "history Command," later in this appendix.)

To repeat a recent command, do the following:

!!--repeat the most recent command
!nn--repeat command nn
!aaa--repeat the command beginning with string aaa
!?aaa--repeat the command containing the string aaa

To modify and repeat the most recent command, do the following:

^aaa^bbb--replace the string aaa with the string bbb in 
the most recent command

To add a string to the end of a previous command and repeat it, do the following:

!!aaa--add string aaa to the end of the most recent command
!nn aaa--add string aaa to the end of command nn
!aaa bbb--add string bbb to the end of the command beginning with string aaa
!?aaa bbb--add string bbb to the end of the command containing the string aaa

Connecting to Catalyst Administration

There are two ways to connect to the admin. interface: the admin. port (EIA/TIA-232) or Telnet. The admin. port allows fixed baud rates. All Telnet sessions are automatically disconnected after remaining idle for 20 minutes. When connecting, "cisco Systems Console" is displayed.

Connection via EIA/TIA-232

A connection via EIA/TIA-232 appears as follows:

Cisco Systems Console
Enter password:
Sorry. Try again.
Enter password:
Console>
Console>
Console> quit

Connection via Telnet

To use Telnet, you must have set the IP address for the switch. Up to 12 simultaneous Telnet sessions are possible. To access the switch with Telnet, perform the following steps:

Step 1 On the remote host, enter the following command, where hostname is the host name or IP address of the switch:

% telnet hostname

Step 2 Enter the admin. interface password.

Note The password default is Return unless you have set a password using the set password command described later in this appendix.

Step 3 When you are finished, enter quit to exit the Telnet session. Following is sample output of a Telnet session:

% telnet catalyst1

Trying 192.122.173.201 ...

Connected to catalyst1.

Escape character is '^]'.

Cisco Systems Console

Enter password:

Sorry. Try again.
E

nter password:

Console>

Console> quit

Connection closed by foreign host.

Top-Level Commands

There are two categories of commands: privileged and normal. (See Table C-1.)

Privileged commands are available only after you invoke the enable command. They are used for system configuration and by end users for troubleshooting basic problems. Certain commands are available, and certain displays have extra information in privileged mode. The designation (enable) appears on your screen in sample displays to indicate privileged commands and when the system is in privileged mode.

Normal commands are available in all cases, and are used by end users for everyday operations.

Table C-1: Top-Level Commands
Command Description Mode¹
clear Clears, use clear help for more info P
configure Configures the system from a terminal or network P
copy Copies code to or from processors P
disable Disables privileged mode P
disconnect Disconnects from the FDDI ring P
download Downloads code to a processor P
enable Enables privileged mode N
help Shows this message N
history Shows the contents of the history substitution buffer N
ping Sends echo packets to hosts N
quit Exits out of the console N
reset Resets the system P
set Sets, use set help for more info N
show Shows use show help for more info N
slip Attaches or detaches SLIP² interfaces P
test Tests, use test help for more information P
upload Uploads code to a processor P
wait Waits for n seconds N
write Writes system configuration to a terminal or network P

¹ N = normal; P = privileged.
² SLIP = Serial Line Internet Protocol

Displaying Information about Commands

Use the ? command to display usage and syntax information about a specific command or to list groups of commands. In normal mode, use the ? command to display a list of top-level commands, as follows:

Console> ? Commands: ---------------------------------------------------------------------- enable Enable privileged mode help Show this message history Show contents of history substitution buffer ping Send echo packets to hosts quit Exit out of the console set Set, use 'set help' for more info show Show, use 'show help' for more info wait Wait for x seconds Console>

Note The overall function of the ? command is the same as the help command.

In privileged mode, use the ? command to display a list of commands, as follows:

Console> enable Enter password: Console> (enable) ? Commands: ---------------------------------------------------------------------- clear Clear, use 'clear help' for more info configure Configure system from terminal/network connect Connect to FDDI ring copy Copy code to/from processors disable Disable privileged mode disconnect Disconnect from FDDI ring or disconnect user session download Download code to a processor enable Enable privileged mode help Show this message history Show contents of history substitution buffer ping Send echo packets to hosts quit Exit out of the console reset Reset the system set Set, use 'set help' for more info show Show, use 'show help' for more info slip Attach/detach Serial Line IP interface test Test, use 'test help' for more info upload Upload code to a processor wait Wait for x seconds write Write system configuration to terminal/network Console> (enable)

Note In general, you can use the ? command appended to any command associated with a group of commands: alias, set, show, and so forth. Or you can append it to any specific command for a list of usage and syntax information. The overall function of the ? command is the same as the help command. For an example of how the ? command can be used to display usage and syntax information about a specific command, refer to the
clear alias command description.

See also set snmp help and show snmp.

clear trunk

Use the clear trunk command to clear partial information in the trunk port table or convert trunk link back to bridge ports. This command disables transitencapsulation if the mode is on. If VLANs are specified, only those VLANs are cleared from the trunk port table. When all VLANs in the trunk port are cleared, the port automatically converts back to a regular bridge port. Following is a sample display:

Console> (enable) clear trunk help Usage: clear trunk [vlans] (An example of vlans is 1,3,865-869) Console> (enable) clear trunk Port 1 no longer a trunk port

See also set trunk and show trunk.

configure Command

Use the configure network command to download a configuration batch file (designated by filename) from a TFTP server (designated by the server) and then execute the commands in the file. Following is a sample display of the configure command:

Console> (enable) configure ? Usage: configure network configure terminal configure <host> <file> Console> (enable) configure cres new.cfg

If the server is not specified, the default is the first entry in the SNMP trap receiver table.

The configure terminal command prompts you to use the set commands to configure the system. Following is a sample display:

Console> (enable) configure terminal This function provided by set commands. Use 'set help' for more info. Console> (enable)

Configuration files are simply multiple Catalyst commands collected in a file. Each Catalyst command is entered on one line. The file should be delimited by begin and end statements and may have comments (identified by a pound sign [#]) as the first character on the line; however, comments must be on lines by themselves. Some commands prompt you for input or confirmation. With input commands, responses should follow the command on the next line(s) to ensure proper operation.

Note Some confirmations prompted for in a Telnet session are not in EIA/TIA-232 connection sessions.

Configuration files should consist only of ASCII text, and should not be larger than 4,608 bytes (4.5 KB).

Following is a sample configuration:

show time set ip alias conc7 198.103.219.207 set ip alias montreux 198.103.219.40 set ip alias cres 192.102.174.42 set prompt catalyst5> set password #empty string old password pingpong pingpong end #

Following is a sample admin. session:

Usage: configure network configure terminal configure <host> <file> Console> (enable) configure 192.122.174.42 catalyst5.cfg Configure using catalyst5.cfg from 192.122.174.42 (y/n) [n]? y >> show time Wed Mar 30 1994, 17:42:50 >> set ip alias conc7 198.133.219.207 IP alias added. >> set ip alias montreux 198.133.219.40 IP alias added. >> set ip alias cres 192.122.174.42 IP alias added. >> set prompt catalyst5> >> set password Enter old password: Enter new password: pingpong Retype new password: pingpong Password changed. catalyst5> (enable)

When you enter the configure network command, you are prompted for the host server, then for the configuration filename.

copy Command

Use the copy command to copy data movement processor (DMP) or network management processor (NMP) image files between the network host and Flash memory using the TFTP protocol. Following is a sample display:

Console> (enable) copy Usage: copy tftp <nmp|dmp> copy <nmp|dmp> tftp Console> (enable) copy nmp tftp IP address or name of host? happy Name of file to copy to? nmpflash.31 Upload NMP image to nmpflash.31 on happy (y/n) [n]? y Done. Console> (enable) copy tftp nmp IP address or name of host? happy Name of file to copy from? nmpflash.31 This command will disconnect your telnet session. Download NMP image nmpflash.31 from happy (y/n) [n]? y Connection closed by foreign host. %

disable

Use the disable command to turn off enable mode, as follows:

Console> (enable) disable Console>

See also the "enable Command " section.

disconnect Command

Use the disconnect command to temporarily disconnect the FDDI port from the FDDI ring temporarily without disconnecting the FDDI cables. The default is connect. Following is a sample display:

Console> (enable) disconnect Usage: disconnect <fddi|admin|host> Console> (enable) disconnect fddi This command will disconnect the switch from the FDDI ring. Do you want to continue (y/n) [n]? y Disconnected from FDDI ring. Console> (enable) disconnect 198.134.214.4 Telnet session 198.134.214.4 disconnected. Console> (enable)

See also "copy Command" section.

download Command

Use the download command to download code to the network management processor (the default) or the data movement processor. Following is a sample display:

Console> (enable) download Usage: download serial [nmp|dmp] download <host> <file> [nmp|dmp] (nmp=network management processor, dmp=data movement processor, serial downloads via the administration RS-232 port, host is ip alias or IP address: a.b.c.d for a network download) Console> (enable) download happy nmpflash.31 nmp This command will disconnect your telnet session. Download NMP image nmpflash.31 from happy (y/n) [n]? y Connection closed by foreign host. %

Caution If the SUM port is also connected to the TFTP server while you are downloading an image file, you must disconnect the SUM port to avoid creating a loop condition.

enable Command

Use the enable command to turn on privileged mode. Certain commands are available, and certain displays have extra information in privileged mode.

Note The designation (enable) indicates both privileged commands and that the system is in privileged mode.

Following is a sample display:

Console> enable Enter password: Console> (enable)

See also the "clear Commands" section.

help Command

Use the help command to display the following information in normal mode:

Console> help Commands: ---------------------------------------------------------------------- enable Enable privileged mode help Show this message history Show contents of history substitution buffer ping Send echo packets to hosts quit Exit out of the console set Set, use 'set help' for more info show Show, use 'show help' for more info wait Wait for x seconds

ping Command

Use the ping command to send Internet Control Message Protocol (ICMP) echo packets to another node on the network. Following is a sample display:

Console> ping ? Usage: ping <host> ping -s <host> [packet_size] [packet_count] (host is ip alias or IP address in dot notation: a.b.c.d) Console> ping elvis Console> elvis is alive Console> ping -s elvis ping elvis: 56 data bytes 64 bytes from elvis: icmp_seq=0. time=11 ms 64 bytes from elvis: icmp_seq=1. time=8 ms 64 bytes from elvis: icmp_seq=2. time=8 ms 64 bytes from elvis: icmp_seq=3. time=7 ms 64 bytes from elvis: icmp_seq=4. time=11 ms 64 bytes from elvis: icmp_seq=5. time=7 ms 64 bytes from elvis: icmp_seq=6. time=7 ms ^C ----elvis PING Statistics---- 7 packets transmitted, 7 packets received, 0% packet loss round-trip (ms) min/avg/max = 7/8/11 Console>

Following are options of the ping command:

-s--sends one datagram per second, printing one line of output for every response received. The ping command does not return any output when no response is received.

Note Enter Ctrl-C to stop pinging.

packet size and packet count--Specifies a packet size and the number of packets to send. Packet sizes range from 1 to 2,000 bytes, with a default of 56 bytes. The actual packet size is eight bytes larger because the switch adds header information.

Following are sample results of the ping command:

Normal response--The normal response occurs in one to ten seconds, depending on network traffic.

Destination does not respond--If the host does not respond, a "no answer" message appears in ten seconds.

Destination unreachable--The gateway given in the route table for this destination indicates that the destination is unreachable.

Network or host unreachable--The switch did not find a corresponding entry in the route table.

Note If you assigned an IP alias to a host address (see "set ip alias" later in this appendix), you can specify this alias in the ping command instead of in the IP address.

quit Command

Use the quit command to quit the current admin. interface session, as follows:

Console> quit Connection closed by foreign host.

reset Command

Use the reset command to reset the system. This command is available only in privileged mode.Following is a sample display:

Console> (enable) reset This command will reset the system and disconnect your telnet session. Do you want to continue (y/n) [n]? y Connection closed by foreign host.

Console> (enable) set arp 198.133.219.232 00:40:0b:40:bc Arp entry added Console> (enable)

See also clear arp and show arp.

set bridge help

Use the set bridge help command to show the following display in privileged mode:

Console> (enable) set bridge help Set bridge commands: ---------------------------------------------------------------------- set bridge help Show this message set bridge ipx Set default IPX translation set bridge vlan Set bridge Virtual LAN

set bridge ipx

As a normal function, the Catalyst 1200 series switch can forward Internetwork Packet Exchange (IPX) packets received on FDDI ports to Ethernet ports, or it can forward IPX packets received on Ethernet ports to FDDI ports. To do this, the switch must be configured for specific IPX protocol translations. By default, the following IPX protocol translations are configured:

FDDI SNAP to Ethernet 802.3 RAW

FDDI 802.2 to Ethernet 802.3

Ethernet 802.3 RAW to FDDI SNAP

You can customize these settings if your environment requires it. Following is a sample display:

Console> (enable) set bridge help Set bridge commands: ---------------------------------------------------------------------- set bridge help Show this message set bridge ipx Set default IPX translation set bridge vlan Set bridge Virtual LAN Console> (enable) set bridge ipx Usage: set bridge ipx snaptoether <8023|SNAP|EII|8023RAW> set bridge ipx 8022toether <8023|SNAP|EII|8023RAW> set bridge ipx 8023rawtofddi <8022|SNAP|FDDIRAW> Console> (enable) set bridge ipx snaptoether 8023RAW snaptoether translation set Console> (enable)

set bridge vlan

Use the set bridge vlan command to group ports into a bridge VLAN. This command is only available in privileged mode. The default setting is all ports (FDDI port 1 and Ethernet ports 3 through 10) in bridge VLAN 1. Following is a sample display:

Console> (enable) set bridge vlan Usage: set bridge vlan <vlan> <ports> (vlan = 1..1000, an example of ports is 1,3-5,9) Console> (enable) set bridge vlan 10 1,3,9 Bridge-Vlan Ports ----------- -------------------- 10 1,3,9 Console> (enable)

set fddi tlmin

Use the set fddi tlmin command to change the TL_MIN timer value for an FDDI port. The TL_MIN parameter sets the minimum time to transmit a Physical Layer Protocol (PHY) line state before advancing to the next physical connection management (PCM) state. This setting affects the station and switch interoperability and might hinder the implementation of FDDI repeaters. By default, the TL_MIN parameter is set to 40 microseconds. Following is a sample display:

Console> (enable) set fddi tlmin Usage: set fddi tlmin <port_num> <time> (time = 40..1340006 usec) Console> (enable) set fddi tlmin 1 40 Port 1 tl_min set to 40 usecs. CAT2> (enable) Console> (enable)

set fddi tnotify

Use the set fddi tnotify command to change the TNotify timer value for an FDDI ring. The TNotify parameter sets the interval (in seconds) between neighbor notification frames. These frames are sent out to notify neighboring devices of FDDI module MAC addresses. The default setting (30 seconds) is usually sufficient. Following is a sample display:

Console> (enable) set fddi tnotify Usage: set fddi tnotify <time> (time = 2..30 seconds) Console> (enable) set fddi tnotify 16 System SMT T-Notify set. Console> (enable)

set fddi treq

Use the set fddi treq command to change the TReq value for an FDDI ring.The TRequest parameter specifies the FDDI switch value for the Token Ring Timer (TRT) for negotiating the TRT with other stations. The TRT is used to control ring scheduling during normal operation and to detect and recover from serious ring error situations. When the TRT value expires, the station uses the TRequest value to negotiate with other stations for the lowest value. The default setting of 165,000 microseconds is sufficient for most networks.

Following is a sample display:

Console> (enable) set fddi treq Usage: set fddi treq <time> (time = 2502..16500 usec) Console> (enable) set fddi treq 165000 MAC T-Request set. Console> (enable)

The user data string can be a term identifying the function of the network node or the users connected to the network node. Following is a sample display:

Console> (enable) set fddi userdata Usage: set fddi userdata [userdata_string] Console> (enable) set fddi userdata Fred's Switch System SMT User Data set. Console> (enable)

set filter

Use the set filter command to selectively receive frames based on criteria other than source address, for example, frame contents, vendor code, or protocol type. Custom filtering operates after the frame is received (after a CAM reject/receive decision). It does not override the forwarding information in the CAM. See the section "Access Lists With Broadcast Suppression" in the chapter "Feature Configuration" for detailed configuration examples.

Note The set filter command is used to filter packets received at the port. It also does not filter packets transmitted from the port.

The filtering types are as follows:

MAC layer address

Vendor code

Protocol type

User defined access lists

Broadcast and multicast packets

The set filter command sets the custom port filter variables used to allow access list filtering.

Following is a sample display:

Console> (enable) set filter help Commands: ----------------------------------------------------------------------- set filter macaddress Set MAC address filter set filter vendor Set Vendor ID filter set filter protocol Set protocol type filter set filter test Set tests for complex filter set filter complex Set complex filter set filter broadcast Set broadcast packets per second

set interface

Use the set interface command to configure network interfaces by assigning network addresses, subnet masks, broadcast addresses, and destination addresses for FDDI, Ethernet, and SLIP interfaces. You can also use the set interface command to bring the interface up or down.

Following are the interface types:

sc0 (SUM port)--Assign the Catalyst 1200 series switch IP address to this interface type.

sl0--Use this interface type when configuring an SLIP connection on the switch.

Note After SLIP is enabled on the admin. port, an EIA/TIA-232 terminal cannot access the Catalyst Switch through this port.

lo0--Use this interface type to configure an internal loopback for the switch.

1, 3 through 10--Use the port number to assign an IP address to a specific port. Port 1 is the FDDI port. Ports 3 through 10 are Ethernet ports. See the section "Virtual Network Services (VNS)" in the chapter "Feature Configuration" for a detailed IP address assignment description.

Note Multiple route groups require different IP addresses.

The interface defaults are:

ip_address--0.0.0.0

netmask--255.0.0.0

broadcast--0.0.0.0

Following is a sample display:

Console> (enable) set interface

Usage: set interface <if_name|if_number> <ip_address> <net_mask> [broadcast_address]

set interface <if_name> <slip_address> <dest_address>

set interface <if_name|if_number> <up|down>

Port--Displays the port number (1/A or 2/B for CDDI/FDDI, and 3 through 10 for Ethernet).

Name--Contains the name of the designated port, and displays only if you have given the port a name using the set portname command.

Status--Shows the port status as one of the following:

Ok--The port is connected. The link status LED is green.

Minor--A signal is detected, but the port is not connected. The link status LED is orange.

Monitor--The port is configured as destination port using the set span command.

Other--The port is not connected.

Curr-Path--Shows the connection state of the port as follows:

Connecting--The port is attempting to connect or is disconnected.

Standby--The connection is withheld or is the inactive port of a dual homing switch.

Active--The port has made connection.

Other--The switch is unable to determine the connection state.

Type--Specifies the type of port as one of the following values:

A--A port

B--B port

U--Undetermined

Neigh--Indicates the type of port attached to this port (called the neighbor port). The neighbor port can be one of the following types:

A--A port

B--B port

S--Slave port

M--Master port

U--Undetermined port

Media--Indicates the media capabilities of the indicated port as follows:

mlt-3--The port uses MLT-3 (CDDI) media.

Wrap_A--Port 1/A is connected to the ring, and port 2/B is isolated.

Wrap-B--Port 2/B is connected to the ring, and port 1/A is isolated.

Thru--Ports 1/A and 2/B are connected to the primary and secondary path.

Other--Occurs if the switch cannot determine the configuration control element state.

ECM-St--Shows the current state of the entity coordination management (ECM) for the switch. ECM controls the bypass switch of the physical medium dependent (PMD) layer and signals the physical connection management (PCM) when the media is available. It also coordinates the trace function and initiates a path test after a trace to localize the suspected fault. ECM-St may appear as one of the following values:

Out--Occurs when waiting for a connect request.

In--Shows the normal state for a completed connection.

Trace--Determines the location of a stuck beacon condition.

Leave--Allows sufficient time to break existing connections.

Path-Test--This state is reached after leaving the trace state.

Insert--Allows for the switching time of the bypass.

Check--Confirms that both the primary and secondary bypass switches have switched.

Deinsert--Allows enough time for the bypass switch to deinsert.

Other--Shows if the switch cannot determine the ECM state.

Bypass--Tells you whether or not an optical bypass switch is connected to the switch (present or absent). If you install or remove an optical bypass switch, reset the switch.

System Contact--Displays the name of the person managing the system.

System Location--Shows a description of where the system is located.

Console> (enable) test snmp Commands: ------------------------------------------------------------------------- test snmp help Show this message test snmp trap Send trap message to SNMP trap receivers Console> (enable) test snmp trap Usage: test snmp trap <trap_number> [specific_number] Console> (enable) test snmp trap 0 SNMP trap message sent. Console> (enable)

upload Command

Use the upload command to upload the Flash memory image file from the catalyst to a network host to create a backup file. The file must be created in advance and saved in the tftpboot directory.

Following is a sample display:

Console> (enable) upload Usage: upload <host> <file> <nmp|dmp> (nmp=network management processor, dmp=data movement processor, host is ip alias or IP address: a.b.c.d) Console> (enable) upload happy nmpxx.bin nmp Upload NMP image to nmpxx.bin on happy (y/n) [n]? y / Done. Console> (enable)

wait Command

Use the wait command to pause the console output for the number of seconds indicated. Following is a sample display:

Console> wait ? Usage: wait <seconds> Console> wait 2

write Command

Use the write command to write the Catalyst 1200 series switch configuration either to an existing file in a network host tftpboot directory or to the terminal screen display.

Use the ASCII configuration file uploaded by the write terminal command to configure the same switch or edit to configure another Catalyst Switch. (See the section "configure Command," earlier in this appendix.) The uploaded file is the same output as the file generated by the write terminal command, with the following exceptions:

The configuration file should end with a single line containing the word "end" followed by a carriage return.

Passwords are saved in the configuration file as clear text and do not echo on the screen.

A blank line should follow the set password and set enablepass commands, assuming no password is to be configured.

A blank line should follow each occurrence of the following command line:

set port port disable

The blank line is needed to display the confirmation prompt with the no default. When these commands are called from a Telnet session, they are not executed because they may disconnect the Telnet session. It is recommended that you execute the configure command from the EIA/TIA-232 connection, not from a Telnet session.

A set attach command type change made from a configuration file is set, but the switch must be reset for the attachment type change to be implemented.

The write terminal command functions the same as the copy command. Refer to the "copy Command" section for information about this command.

Following is a sample display:

Console> (enable) write Usage: write network write terminal write <host> <file> Console> (enable) write network IP address or name of host? happy Name of configuration file to write? catalyst5.cfg Upload configuration to catalyst5.cfg on happy (y/n) [y]? y / Done. Console> (enable)
