To list PNNI neighboring peers for a switch, use the show atm pnni neighbor EXEC command.
show atm pnni neighborThis command has no keywords or arguments.
EXEC
The show atm pnni neighbor command displays information about adjacencies. Multiple links can be connected to the same neighboring peer. The output from the show command displays all PNNI interfaces to each neighboring peer, including the local port, the remote port, and the hello state for each interface. Based on the port identifiers, PNNI derives the port string if the remote switch is a LightStream 1010 ATM switch.
The switch may not translate the port identifier into a meaningful string (such as ATM 3/0/0) if the remote switch is not a LightStream 1010 ATM. For this reason both the port string and the port identifier are displayed. At any time only one interface to each neighboring peer is used for flooding of PTSEs. This interface is identified as (flooding port) in the show command output.
The following is sample output from the show atm pnni neighbor command.

To display the topology connectivity information from the internal topology database, use the show atm pnni topology EXEC command.
show atm pnni topology [node node-name] [detail]| node | Displays the topology information about a specific node identified by the node-name. |
| node-name | Identifies the node by a specific name. |
| detail | Displays more detailed information and is used as the last keyword of the show command. |
EXEC
The topology as seen from the PNNI database can be displayed using the show atm pnni topology command. This command shows all accessible PNNI nodes in the network (through PTSEs) and any links to neighboring nodes.
PNNI nodes are represented internally by an 8-bit number. This command shows the mapping between the internal node number and the full 22-byte node ID.
A link status of "up" indicates the link is advertised by the node on both ends of a link. A link status of "2 down" indicates the remote node (neighbor) did not advertise the link. Links that are down are not used for path selection by the current node.
The following is sample output from the show atm pnni topology command.

To display all local or network-wide reachable address prefixes in this switch's ATM routing table, use the show atm route EXEC command.
show atm route [[address_prefix [longer_prefix]] | local]| address_prefix | Displays all routing table entries for the specified prefix. |
| local | Displays information about reachable addresses attached to this switch only. This includes static routes configured on this switch and routes learned using ILMI address registration. |
| longer_prefix | Displays all routing tables entries for longer prefixes that match the specified address prefix. |
EXEC
This command displays the ATM address prefixes in the ATM routing table. Prefixes are tagged with either E or I. The E represents external prefixes that were configured using the atm route command. The I represents internal prefixes registered through ILMI or generated internally by the system for other purposes (for example; soft-PVP support). The prefix is displayed in the following notation and the prefix/length shows the length in bits:
1234.24/16
The node represents the switch that generated the route (see show atm pnni node-id command for node number mappings). Node 1 represents this switch, while other numbers represent switches learned from the network. The port number, the protocol that generated the advertisement, the timestamp, and the port status (or summary information) are also displayed.
The link is DN in the following cases:

To display the contents of the BOOT environment variable, the name of the configuration file pointed to by the CONFIG_FILE environment variable, and the contents of the BOOTLDR environment variable, use the show boot EXEC command.
show bootThis command has no arguments or keywords.
EXEC
The show boot command allows you to view the current settings for the following environment variables:
The BOOT environment variable specifies a list of bootable images on various devices. The config_file environment variable specifies the configuration file used during system initialization. The BOOTLDR environment variable specifies the Flash device and filename containing the rxboot image that ROM uses for booting. You set these environment variables with the boot system, boot config, and boot bootldr commands, respectively.
The following is sample output from the show boot command.
Switch# show boot
BOOT variable =
CONFIG_FILE variable =
Current CONFIG_FILE variable =
BOOTLDR variable = bootflash:/home/cyadaval/ls1010-i-m.bin.Z
Configuration register is 0x0
In the sample output, the BOOT environment variable contains a null string: that is, a list of bootable images is not specified.
The run-time value for the config_file environment variable points to the switch-config file on the Flash memory card inserted in the first slot of the ASP card. That is, during the run-time configuration, you have modified the config_file environment variable using the boot config command, but you have not saved the run-time configuration to the startup configuration. To save your run-time configuration to the startup configuration, use the copy running command.
The BOOTLDR environment variable does not yet exist. That is, you have not created the BOOTLDR environment variable using the boot bootldr command.

| Field | Description |
|---|---|
| Buffer elements | Buffer elements are small structures used as placeholders for buffers in internal operating system queues. Buffer elements are used when a buffer may need to be on more than one queue. |
| Free list | Total number of the currently unallocated buffer elements. |
| Max allowed | Maximum number of buffers that are available for allocation. |
| Hits | Count of successful attempts to allocate a buffer when needed. |
| Misses | Count of buffer allocation attempts that resulted in growing the buffer pool to allocate a buffer. |
| Created | Count of new buffers created to satisfy buffer allocation attempts when the available buffers in the pool have already been allocated. |
| Small buffers | Buffers that are 104 bytes long. |
| Middle buffers | Buffers that are 600 bytes long. |
| Big buffers | Buffers that are 1524 bytes long. |
| VeryBig buffers | Buffers that are 4520 bytes long. |
| Large buffers | Buffers that are 5024 bytes long. |
| Huge buffers | Buffers that are 18024 bytes long. |
| Total | Total number of this type of buffer. |
| Permanent | Number of these buffers that are permanent. |
| Free list | Number of available or unallocated buffers in that pool. |
| Min | Minimum number of free or unallocated buffers in the buffer pool. |
| Max allowed | Maximum number of free or unallocated buffers in the buffer pool. |
| Hits | Count of successful attempts to allocate a buffer when needed. |
| Misses | Count of buffer allocation attempts that resulted in growing the buffer pool in order to allocate a buffer. |
| Trims | Count of buffers released to the system because they were not being used. This field is displayed only for dynamic buffer pools, not interface buffer pools, which are static. |
| Created | Count of new buffers created in response to misses. This field is displayed only for dynamic buffer pools, not interface buffer pools, which are static. |
| Total | Total number of this type of buffer. |
| Permanent | Number of these buffers that are permanent. |
| Free list | Number of available or unallocated buffers in that pool. |
| Min | Minimum number of free or unallocated buffers in the buffer pool. |

| Hits | Count of successful attempts to allocate a buffer when needed. |
| Fall backs | Count of buffer allocation attempts that resulted in falling back to the public buffer pool that is the smallest pool at least as big as the interface buffer pool. |
| Max Cache Size | Maximum number of buffers from interface pool that can be in the buffer pool's cache. Each interface buffer pool has its own cache. These are not additional permanent buffers; they come from the interface's buffer pools. Some interfaces place all buffers from the interface pool into the cache. In this case, it is normal for the free list to display 0. |
| Failures | Total number of allocation requests that failed because no buffer was available for allocation; the datagram was lost. Such failures normally occur at interrupt level. |
| No memory | Number of failures that occurred because no memory was available to create a new buffer. |

To display the system clock, use the show clock EXEC command.
show clock [detail]| detail | (Optional) Indicates the clock source (NTP, VINES, and so forth) and the current summer-time setting (if any). |
EXEC
The system clock keeps an "authoritative" flag that indicates whether or not the time is authoritative (believed to be accurate). If system clock has been set by a timing source, the flag is set. If the time is not authoritative, it is used only for display purposes. Until the clock is authoritative and the "authoritative" flag is set, the flag prevents the switch from causing peers to synchronize to itself when the switch time is invalid.
The symbol that precedes the show clock display indicates the following:
The following sample output shows that the current clock is authoritative and that the time source is NTP.

To display power-on diagnostic statistic information, use the show diag EXEC command.
show diag [environment | power-on]| environment | Displays information about environmental status. |
| power-on | Show power-on diagnostics status. |
EXEC
The power-up or hardware reset diagnostics provide full sets of test suites to test the switch. The test results are stored in the switch memory and an interface is provided using the show diag power-on command. If an error is detected during the test, the ASP STATUS LED turns red.
If there are any failures during the power-on sequence, a copy of the output from the show diag power-on command can be forwarded to TAC for diagnosis.
The following is sample output from the show diag power-on EXEC command.

To display the configuration stored in a specified file, use the show file EXEC command.
show file [device:] filename| device: | (Optional) Device containing the configuration file. The colon (:) is required. Valid devices are as follows:
· bootflash: This device is the internal Flash memory. · slot0: This device is the first PCMCIA slot on the ASP card and is the initial default device. · slot1: This device is the second PCMCIA slot on the ASP card. If you omit the device: argument, the system uses the default device specified by the cd command. |
| filename | Name of the file. The file can be of any type. The maximum filename length is 63 characters. |
EXEC
When showing the configuration, the switch informs you whether the displayed configuration is a complete configuration or a distilled version. A distilled configuration is one that does not contain access lists.

| filesys | (Optional) Shows the Device Info Block, the Status Info, and the Usage Info. |
| device | (Optional) Specifies the device about which to show Flash information. The device is optional but when it is used, the colon (:) is required. When it is omitted, the default device is that specified by the cd command. Valid devices are as follows:
bootflash: This device is the internal Flash memory. slot0: This device is the first PCMCIA slot on the ASP card. slot1: This device is the second PCMCIA slot on the ASP card. |
EXEC
The show flash command displays the type of Flash memory present, any files that might currently exist in PCMCIA slot0: Flash memory, and the amounts of Flash memory used and remaining.
When you specify a PCMCIA slot as the device, the switch displays the layout and contents of the Flash memory card inserted in the specified slot of the ASP card. When you omit the device: argument, the switch displays the default device specified by the cd command. Use the pwd command to show the current default device.
The following is sample output from the show flash command.

As the display shows, the Flash memory can store and display multiple, independent software images for booting itself or for TFTP server software for other products. This feature is useful for storing default system software. These images can be stored in compressed format (but cannot be compressed by the switch).
To eliminate any files from Flash memory (invalidated or otherwise) and free up all available memory space, the entire Flash memory must be erased; individual files cannot be erased from Flash memory.
Table 18-19 describes the show flash display fields.
| Field | Description |
|---|---|
| Name | Filename and status of a system image file. The status [invalidated] appears when a file has been rewritten (recopied) into Flash memory. The first (now invalidated) copy of the file is still present within Flash memory, but it is unusable because of the newest version. |
| crc | Address of the file in Flash memory. |
| Length | Size of the system image file (in bytes). |
| Bytes available/used | Amount of Flash memory used/available amount of Flash memory. |

To list the commands you have entered in the current EXEC session, use the show history EXEC command.
show historyThis command has no arguments or keywords.
EXEC
The command history feature provides a record of EXEC commands you have entered. The number of commands the history buffer records is determined by the history size line configuration command or the terminal history size EXEC command.
Table 18-21 lists the keys and functions you can use to recall commands from the command history buffer.
| Key | Function |
|---|---|
| Ctrl-P or Up arrow | Recalls commands in the history buffer in a backward sequence, beginning with the most recent command. Repeat the key sequence to recall successively older commands. |
| Ctrl-N or Down arrow | Returns to more recent commands in the history buffer after recalling commands with Ctrl-P or the Up arrow. Repeat the key sequence to recall successively more recent commands. |

To display the active accounting or checkpointed database or to display access-list violations, use the show ip accounting EXEC command.
show ip accounting [access-violations | checkpoint | output-packets]| access-violations | (Optional) Shows the access violation in the accounting database. |
| checkpoint | (Optional) Indicates the checkpointed database should be displayed. |
| output-packets | (Optional) Indicates that information pertaining to packets that passed access control and were successfully routed should be displayed. |
If neither the output-packets nor access-violations keyword is specified, show ip accounting displays information pertaining to packets that passed access control and were successfully routed.
EXEC
If you do not specify any keywords, the show ip accounting command displays information about the active accounting database.
To display IP access violations, you must give the access-violations keyword on the command. If you do not specify the keyword, the command defaults to displaying the number of packets that have passed access lists and were routed.
To use this command, you must first enable IP accounting on a per-interface basis.
Following is sample output from the show ip accounting command.

EXEC
A switch automatically enters a directly connected route in the routing table if the interface is usable. A usable interface is one through which the switch can send and receive packets. If the switch determines that an interface is not usable, it removes the directly connected routing entry from the routing table. Removing the entry allows the switch to use dynamic routing protocols to determine backup routes to the network (if any).
If the interface can provide two-way communication, the line protocol is marked "up." If the interface hardware is usable, the interface is marked "up."
If you specify an optional interface type, you will see only information on that specific interface.
If you specify no optional arguments, you will see information on all the interfaces.
The following is sample output from the show ip interface command.

The first section of the display includes summary statistics about the activities of the system memory allocator. Table 18-42 describes significant fields shown in the first section of the display.
| Field | Description |
|---|---|
| Head | Hexadecimal address of the head of the memory allocation chain. |
| Free List | Hexadecimal address of the base of the free list. |
| Total (b) | Sum of used bytes plus free bytes. |
| Used (b) | Amount of memory in use. |
| Free (b) | Amount of memory not in use. |
| Largest (b) | Size of largest available free block. |
The second section of the display is a block-by-block listing of memory use. Table 18-43 describes significant fields shown in the second section of the display.
| Field | Description |
|---|---|
| Address | Hexadecimal address of block. |
| Bytes | Size of block in bytes. |
| Prev. | Address of previous block (should match Address field on previous line). |
| Next | Address of next block (should match address on next line). |
| Ref | Reference count for that memory block, indicating how many different processes are using that block of memory. |
| PrevF | Address of previous free block (if free). |
| NextF | Address of next free block (if free). |
| Alloc PC | Address of the system call that allocated the block. |
| What | Name of process that owns the block, or "(fragment)" if the block is a fragment, or "(coalesced)" if the block was coalesced from adjacent free blocks. |

To display the status of TCP connections, use the show tcp EXEC command.
show tcp [line-number] {aux | brief | console | vty}| line-number | (Optional) Absolute line number of the line for which you want to display Telnet connection status. |
| aux | (Optional) Indicates the line number on which to execute the chat script. If you do not specify a line number, the current line number is chosen. If the specified line is busy, the script is not executed and an error message appears. If the dialer-string argument is specified, aux 0 must be entered; this command is not optional if you specify a dialer-string. This command functions only on physical terminal (tty) lines. It does not function on virtual terminal (vty) lines. |
| brief | (Optional) Keyword used to limit the display of information. |
| console | (Optional) Keyword used to display the primary terminal line. |
| vty | (Optional) Keyword used to display the virtual terminal. |

Table 18-53 describes the following lines of output shown in the display:
con0 (console terminal), connection 1 to host MATHOM Connection state is ESTAB, I/O status: 1, unread input bytes: 1 Local host: 172.30.7.18, 33537 Foreign host: 192.31.7.17, 23 Enqueued packets for retransmit: 0, input: 0, saved: 0
| Field | Description |
|---|---|
| con0 | Identifying number of the line. (console terminal) Location string. |
| connection 1 | Number identifying the TCP connection. |
| to host MATHOM | Name of the remote host to which the connection has been made.
Connection state is ESTAB A connection progresses through a series of states during its lifetime. These states follow in the order in which a connection progresses through them.
For more information, see RFC 793, Transmission Control Protocol Functional Specification. |
| I/O status: 1 | Number describing the current internal status of the connection. |
| unread input bytes: 1 | Number of bytes that the lower-level TCP processes read, but the higher level TCP processes have not yet processed. |
| Local host: 192.31.7.18 | IP address of the network server. 33537 Local port number, as derived from the following equation: line-number + (512 * random-number). (The line number uses the lower nine bits; the other bits are random.) |
| Foreign host: 192.31.7.17 | IP address of the remote host to which the TCP connection has been made. |
| 23 | Destination port for the remote host. |
| Enqueued packets for retransmit: 0 | Number of packets waiting on the retransmit queue. These are packets on this TCP connection that were sent but not acknowledged by the remote TCP host. |
| input: 0 | Number of packets that are waiting on the input queue to be read by the user. |
| saved: 0 | Number of received out-of-order packets that are waiting for all packets comprising the message to be received before they enter the input queue. For example, if packets 1, 2, 4, 5, and 6 were received, packets 1 and 2 enter the input queue, and packets 4, 5, and 6 enter the saved queue. |
The following lines of output show the current time according to the system clock of the local host.
Event Timers (current time is 2043535532): The time shown is the number of milliseconds since the system started.
The following lines of output display the number of times that various local TCP timeout values were reached during this connection. In this example, the local host retransmitted 69 times because it received no response from the remote host, and it transmitted an acknowledgment many more times because there was no data on which to piggyback.
Timer: Retrans TimeWait AckHold SendWnd KeepAlive Starts: 69 0 69 0 0 Wakeups: 5 0 1 0 0 Next: 2043536089 0 0 0 0
Table 18-54 describes the fields in the preceding lines of output.
| Field | Description |
|---|---|
| Timer: | The names of the timers in the display. |
| Starts: | The number of times the timer has been started during this connection. |
| Wakeups: | Number of keepalives transmitted without receiving any response. (This field is reset to zero when a response is received.) |
| Next: | The system clock setting that triggers the next time this timer goes off. |
| Retrans | The Retransmission timer is used to time TCP packets that were not acknowledged and are waiting for retransmission. |
| TimeWait | The TimeWait timer is used to ensure that the remote system receive a request to disconnect a session. |
| AckHold | The Acknowledgment timer is used to delay the sending of acknowledgments to the remote TCP in an attempt to reduce network use. |
| SendWnd | The Send Window is used to ensure that there is no closed window due to a lost TCP acknowledgment. |
| KeepAlive | The KeepAlive timer is used to control the transmission of test messages to the remote TCP to ensure that the interface has not been broken without the local TCP's knowledge. |
The following lines of output display the sequence numbers that TCP uses to ensure sequenced, reliable transport of data. The local host and remote host each use these sequence numbers for flow control and to acknowledge receipt of datagrams. Table 18-55 describes the specific fields in these lines of output:
iss: 2043207208 snduna: 2043211083 sndnxt: 2043211483 sndwnd: 1344 irs: 3447586816 rcvnxt: 3447586900 rcvwnd: 2144 delrcvwnd: 83
| Field | Description |
|---|---|
| iss: 2043207208 | Initial send sequence number. |
| snduna: 2043211083 | Last send sequence number the local host sent but has not received an acknowledgment for. |
| sndnxt: 2043211483 | Sequence number the local host is send next. |
| sndwnd: 1344 | TCP window size of the remote host. |
| irs: 3447586816 | Initial receive sequence number. |
| rcvnxt: 3447586900 | Last receive sequence number the local host has acknowledged. |
| rcvwnd: 2144 | Local host's TCP window size. |
| delrcvwnd: 83 | Delayed receive window--data the local host has read from the connection but has not yet subtracted from the receive window the host has advertised to the remote host. The value in this field gradually increases until it is larger than a full-sized packet, at which point it is applied to the rcvwnd field. |
The following lines of output display values that the local host uses to keep track of transmission times so that TCP can adjust to the network it is using. Table 18-56 describes the fields in the following line of output:
RTTO: 565 ms, RTV: 233 ms, KRTT: 0 ms, minRTT: 68 ms, maxRTT: 1900 ms ACK hold: 282 ms
| Field | Description |
|---|---|
| RTTO: 565 ms | Round-trip timeout. |
| RTV: 233 ms | Variance of the round-trip time. |
| KRTT: 0 ms | New round-trip timeout (using the Karn algorithm). This field separately tracks the round-trip time of packets that were retransmitted. |
| minRTT: 68 ms | Smallest recorded round-trip timeout (hard-wired value used for calculation). |
| maxRTT: 1900 ms | Largest recorded round-trip timeout. |
| ACK hold: 282 ms | Time the local host delays an acknowledgment in order to piggyback data on it. |
For more information on these fields, refer to "Round Trip Time Estimation," P. Karn & C. Partridge, ACM SIGCOMM-87, August 1987. Table 18-57 describes the fields in the following lines of output:
Datagrams (max data segment is 536 bytes): Rcvd: 106 (out of order: 0), with data: 71, total data bytes: 83 Sent: 96 (retransmit: 5), with data: 92, total data bytes: 4678
| Field | Description |
|---|---|
| Rcvd: 106 (out of order: 0) | Number of datagrams the local host has received during this connection (and the number of these datagrams that were out of order). |
| with data: 71 | Number of these datagrams that contained data. |
| total data bytes: 83 | Total number of bytes of data in these datagrams. |
| Sent: 96 (retransmit: 5) | Number of datagrams the local host sent during this connection (and the number of these datagrams that had to be retransmitted). |
| with data: 92 | Number of these datagrams that contained data. |
| total data bytes: 4678 | Total number of bytes of data in these datagrams. |
