Following are descriptions of the display fields of the show mac command:

• MAC---Indicates which MAC is being referenced by the data in the other fields.
  

• SMT-Address---Displays the 48-bit MAC address in canonical format (for example 00:40:0b:a0:03:cf).
  

• Curr-Path---Indicates the current path handled by the MAC, and takes one of the following values:
  

  • Primary---The MAC is on the primary path.
    

  • Isolated---The MAC is not on any path but is isolated.
    

  • Unknown---The switch cannot determine the path.
    

• TReq---Shows the time (in microseconds) that the MAC requests as the average token rotation time. You can configure this parameter with the admin. interface set treq command.
  

• TNeg---Contains the TReq value agreed on by all MACs in the ring.
  

• TMax---Holds the maximum time (in microseconds) that the MAC sends out as a TReq value.
  

• TVX---Contains the time (in microseconds) of the MAC valid transmission timer.
  

• Upstream-Nbr---Contains the address of the most recently known upstream neighbor to the MAC.
  

• Downstream-Nbr---Contains the address of the most recently known downstream neighbor to the MAC, the next MAC to receive frames from this MAC.
  

• Old-Upstream-Nbr---Contains the MAC address of the previous upstream neighbor.
  

• Old-Downstream-Nbr---Contains the MAC address of the previous downstream neighbor.
  

• Rcv-Smt---Shows the total number of SMT frames received by the MAC.
  

• Xmit-Smt---Shows the total number of SMT frames transmitted by the MAC.
  

• Rcv-llc---Shows the total number of Logical Link Control (LLC) frames received by the MAC.
  

• Xmit-llc---Shows the total number of LLC frames transmitted by the MAC.
  

• Tvx-Exp-Ct---Displays the number of valid transmission timer (TVX) expirations counted by the MAC.
  

• RingOp-Ct---Shows the number of times that the ring has encountered a break and has restarted.
  

• Rcv-Frms---Shows the total number of frames received by the MAC.
  

• Xmit-Frms---Shows the total number of frames transmitted by the MAC.
  

• Rcv-Multi---Shows the total number of multicast frames received by the MAC.
  

• Xmit-Multi---Shows the total number of multicast frames transmitted by the MAC.
  

• Rcv-Broad---Shows the total number of broadcast frames received by the MAC.
  

• Xmit-Broad---Shows the total number of broadcast frames transmitted by the MAC.
  

• Dely-Exced---Shows the number of frames discarded by this port because of excessive transmission delay through the bridge.
  

• MTU-Exceed---Shows the number of frames discarded by this port because the maximum frame size or MTU has been exceeded.
  

• In-Discard---Shows the number of valid frames received by this port that were discarded (filtered) by the forwarding process.
  

• Lrn-Discard---Shows the number of forwarding database entries that have been or would have been learned but have been discarded because of lack of space.
  

• Last-Time-Cleared---Displays the date and time that the MAC counters were last cleared.

The show port command screen has two sections: one for the CDDI/FDDI ports and one for the Ethernet ports. Following are descriptions of the display fields of the show port command:

• 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:
  

  • Isolated---The port is not connected.
    

  • Primary---The port is inserted in the primary path.
    

  • Concatenated---The port is inserted in both the primary and secondary paths in a concatenated wrap configuration.
    

  • Thru---The port is inserted in both the primary and secondary paths in a thru configuration.
    

• Conn-State---Displays the connection state of the port as follows:
  

  • Disabled---The port has no line module or was disabled by the user.
    

  • 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.
    

  • fiber---The port uses FDDI fiber-optic cable.
    

  • none---This port cannot be used because it is missing a line module card (an internal plug-in circuit board).
    

• Ler-Cond---Shows the link error rate indicator field as either true (an error condition exists on the link) or false (no error conditions exist on the link).
  

• Ler-Est---Refers to the long-term estimated error rate for the link. The value displayed in this field is the exponent of 10--n. For example, if the indicated value is 11, the estimated error rate is 10--11; thus, the higher the value of the exponent, the lower the number and the better the link error rate. Values range from 10--4 to 10--12.
  

• Ler-Alrm---Contains the error rate for the link that generates an alarm. The default is 10--8. The value displayed in this field is the exponent of 10^--n.
  

• Ler-Cutoff---Contains the error rate for the link that disables the port. The default is 10^--7. The value displayed in this field is the exponent of 10^--n.
  

• Lem-Ct---Holds the link error monitor count, which is the number of recorded link errors received. This count is used to estimate the link error rate (Ler-Est). The link error monitor helps measure link performance and isolate faulty links that pass initial tests.
  

• Lem-Rej-Ct---Contains the link error monitor rejected count, which is the number of times a link was disabled because the link error rate reached the cutoff threshold.
  

• Port---Displays the 10BaseT ports numbered 3 through 10.
  

• Name---Contains the name of the designated port. A name is displayed only if you assigned a name using the set portname command.
  

• Status---Indicates the relative condition of the port as one of the following:
  

  • Ok---The port has connection. The link status LED is green.
    

  • Other---The port is not connected.
    

  • Disable---The port is disabled.
    

• Align-Err---Shows the number of frames received on this port that are not an integral number of octets in length and do not pass the frame checksum (FCS) check.
  

• FCS-Err---Shows the number of frames received on this port that are an integral number of octets in length, but do not pass the FCS check.
  

• Xmit-Err---Shows the number of frames for which transmission failed on this port because of an internal MAC-sublayer transmit error.
  

• Rcv-Err---Shows the number of frames for which reception failed on this port because of an internal MAC-sublayer receive error.
  

• Single-Col---Shows the number of frames successfully transmitted on this port for which transmission is inhibited by one collision.
  

• Multi-Coll---Shows the number of frames successfully transmitted on this port for which transmission is inhibited by more than one collision.
  

• Late-Coll---Shows the number of times a collision is detected on this port later than 512 bit times into the transmission of a packet.
  

• Excess-Col---Shows the number of frames for which transmission on this port failed because of excessive collisions.
  

• Carrier-Sense---Shows the number of times the carrier-sense condition was lost or never asserted when attempting to transmit a packet on this port.
  

• Giants---Shows the number of frames received on this port that exceeded the maximum permitted frame size.
  

• Last-Time-Cleared---Displays the date and time that the port counters were last cleared.

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>
