Command

Description

show hardware

Displays the revision number of the hardware.

show diag online (Catalyst 8540 MSR)

To display test results for system diagnostic online tests, use the show diag online command.

show diag online [detail | status] [access | oir | snake]
Syntax Description

detail

Displays test detail for the specified test.

status

Displays test status for the specified test.

access

Ensures connectivity at a configurable interval between the primary route processor and the following:

•Active switch processors

•Standby switch processor, if it is present

•Feature cards

•Port adapters

•Interface modules

Whenever the access test detects a hardware failure, the system issues an error message to the console.

If the access test detects a hardware problem with an active switch processor, the standby switch processor, if present, automatically takes over and becomes an active switch processor. The system generates an SNMP trap when the switchover occurs.

oir

Checks functioning of the switch fabric and interfaces on a per-port basis. The switch router performs these tests when the system boots up and when you insert a port adapter or interface module into a slot. The OIR test sends a packet to the interface loopback and expects to receive it back within a certain time period. If the packet does not reach the port within the expected time period, or the route processor receives a corrupted packet, the system issues an error message to the console, generates an SNMP trap, and brings the port to an administrative down state.

snake

Establishes a connection across all the active ports in the switch router, originating and terminating at the primary route processor. The route processor establishes a connection by sending a packet to each port in turn, which then terminates at the route processor. If the packet does not reach the route processor within the expected time period, or the received packet is corrupted, further testing is performed to isolate and disable the port causing the problem.The size of the packet and frequency of the test are configurable to minimize the impact on system performance.

The snake test supports all ATM interface modules and enhanced Gigabit Ethernet interface modules. It does not support ATM port adapters, Fast Ethernet interface modules, or Gigabit Ethernet interface modules.

Defaults

No default.

Usage Guidelines

The access and snake online diagnostic tests run at user specified intervals and results are stored. The OIR diagnostic test has a variable packet size that can be configured. The show diag online command displays test results.

Diagnostic tests must be enabled by using the diag online command before the show diag online command display current diagnostic test results.

show flash

To display the layout and contents of Flash memory, use one of the following show flash
EXEC commands.

show flash [all | chips | filesys]
Syntax Description

all

Displays the same information as the dir command when used with the /all and /long keywords. This information includes that displayed by the filesys and chips keywords.

Command History

Release

Modification

11.1(4)

New command

Usage Guidelines

The show flash command displays the type of Flash memory present, any files that might currently exist in PC slot0: Flash memory, and the amounts of Flash memory used and remaining.

When you specify a PC slot as the device, the switch router displays the layout and contents of the Flash memory card inserted in the specified slot of the route processor card. When you omit the device: argument, the switch router displays the default device specified by the cd command. Use the pwd command to show the current default device.

Examples

The following example is sample output from the show flash command.
Switch# show flash
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1   .D FFFFFFFF 9099E94C 233F8C  22   2047753  Feb 29 1997 06:30:03 xxxxxx-i-m_Z

3306412 bytes available (4295764 bytes used)
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 18-27 describes the show flash display fields.

Table 18-27 show flash Field Descriptions

Field

Description

Name

Filename and status of a system image file. The invalidated status 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

Field

Description

Flag

Indicates a temporary entry is entered by a name server; the switch removes the entry after 72 hours of inactivity. An entry marked perm is entered by a configuration command and is not timed out. Entries marked OK are considered valid. Entries with question marks (??) are suspect and subject to revalidation. Entries marked EX are expired.

Age

Indicates the number of hours since the switch last referred to the cache entry.

Type

Identifies the type of address, for example, IP, CLNS, or X.121. If you have used the ip hp-host global configuration command, the show hosts command displays these host names as type HP-IP.

Address(es)

Shows the address of the host. One host may have up to eight addresses.

Command Modes

EXEC

Command History

Release

Modification

12.0(4a)W5(11a)

New command. Originally show ima interface (Catalyst 8510 MSR and LightStream 1010)

Usage Guidelines

The show ima interface command has two specific display types, the IMA group information display and the IMA port adapter hardware information display.

The IMA group ATM layer information display is shown using the ima keyword and IMA group number instead of the port number in the hardware interface description.

Note If no ATM keyword is entered, the show ima interface command displays all IMA interfaces that are present in the system.

Note This command is only supported on systems equipped with FC-PFQ.

Examples

The following example shows how to use the show ima interface command with no interface variables to display the ATM layer information for all IMA groups in tabular mode.

Usage Guidelines

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 display of show memory free contains the same types of information as the show memory display, except that only free memory is displayed, and the information is displayed, in order, for each free list.

The first section of the display includes summary statistics about the activities of the system memory allocator.

Table 18-52 describes significant fields shown in the first section of the display.

Table 18-52 show memory Field Descriptions—First Section

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 18-53 describes the significant fields in the second section of the display.

Table 18-53 Characteristics of Each Block of Memory—Second Section

Field

Description

Address

Hexadecimal address of the block.

Bytes

Size of the block, in bytes.

Prev.

Address of the previous block (should match the Address field on previous line).

Next

Address of the next block (should match the address on the next line).

Ref

Reference count for that memory block, indicating how many different processes are using that block of memory.

PrevF

Address of the previous free block (if free).

NextF

Address of the 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.

The show memory io command displays the free IO memory blocks. This command quickly shows how much unused IO memory is available.

The following example is sample output from the show memory io command.

show ncdp path root

To display the NCDP path from the current node to its root clock source, use the
show ncdp path root command.

show ncdp path root
When this command is executed, a PDU is built and sent towards its root clock source. As the PDU traverses nodes in the network, the NCDP entity on each node adds path information to the PDU. When the PDU reaches the node with the root clock source, it is routed back to the originating node. When the PDU is received by the originating node, the accumulated path information is displayed.

Syntax Description

This command has no keywords or arguments.

Usage Guidelines

The operation of this command is asynchronous, and thus the PDU or response PDU could be dropped within the network, causing this command to fail.

Table 18-57 describes the significant fields shown in the two displays.

Table 18-57 show processes Field Descriptions

Field

Description

utilization for five seconds

CPU utilization for the last 5 seconds, 1 minute, and 5 minutes.

route processor utilization for five seconds (Catalyst 8540 MSR)

CPU utilization for the last 5 seconds, 1 minute, and 5 minutes.

PID

Process ID.

Q

Process queue priority. Possible values are: H (high), M (medium), L (low).

Ty

Scheduler test. Possible values: * (currently running), E (waiting for an event), S (ready to run, voluntarily relinquished processor), rd (ready to run, wakeup conditions occurred), we (waiting for an event), sa (sleeping until an absolute time), si (sleeping for a time interval), sp (sleeping for a time interval [alternate call]), st (sleeping until a timer expires), hg (hung; the process never executes again), xx (dead; the process has terminated, but has not yet been deleted).

PC

Current program counter.

Runtime (ms)

CPU time the process has used, in milliseconds.

Invoked

Number of times the process has been invoked.

uSecs

Microseconds of CPU time for each process invocation.

Stacks

Low water mark/total stack space available (in bytes).

TTY

Terminal that controls the process.

Process

Name of process.

five seconds

CPU utilization by task in last 5 seconds (in hundredths of seconds).

one minute

CPU utilization by task in last minute (in hundredths of seconds).

five minutes

CPU utilization by task in last 5 minutes (in hundredths of seconds).

Note Because the network server has a 4-ms clock resolution, run times are considered reliable only after a large number of invocations or a reasonable, measured run time.

show switch counters

To display the counters on the switch router's interfaces, use the show switch counters EXEC command.

show switch counters
Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Usage Guidelines

This command does not use IPC to get the information and can be used to find the port state prior to using any IPC-based commands, such as the show controllers command. The counts reflect the actual number that the interface has received; these counter values are not reset when the clear counters command is issued.

Examples

The following example is sample output from the show switch counters command:
Router# show switch counters

Field

Description

con0

Number identifying the line (console terminal) and 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. A connection progresses through these states in the following order:

•LISTEN—Waiting for a connection request from any remote TCP and port.

•SYNSENT—Waiting for a matching connection request after having sent a connection request.

•SYNRCVD—Waiting for a confirming connection request acknowledgment after having both received and sent a connection request.

•ESTAB—Indicates an open connection; data received can be delivered to the user. This is the normal state for the data transfer phase of the connection.

•FINWAIT1—Waiting for a connection termination request from the remote TCP or an acknowledgment of the connection termination request previously sent.

•FINWAIT2—Waiting for a connection termination request from the remote TCP host.

to host MATHOM (Continued)

•CLOSEWAIT—Waiting for a connection termination request from the local user.

•CLOSING—Waiting for a connection termination request acknowledgment from the remote TCP host.

•LASTACK—Waiting for an acknowledgment of the connection termination request previously sent to the remote TCP host.

•TIMEWAIT—Waiting for enough time to pass to be sure the remote TCP host has received the acknowledgment of its connection termination request.

•CLOSED—Indicates no connection state at all.

For more information, refer to 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 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.

Table 18-74 describes the fields in the preceding lines of output.

Table 18-74 show tcp Field Descriptions—Second Section of Output

Field

Description

Timer:

Names of the timers in the display.

Starts:

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:

System clock setting that triggers the next time this timer goes off.

Retrans

Retransmission interval time TCP packets that were not acknowledged and are waiting for retransmission.

TimeWait

TimeWait timer ensures that the remote system receives a request to disconnect a session.

AckHold

Acknowledgment timer delays the sending of acknowledgments to the remote TCP in an attempt to reduce network use.

SendWnd

Send Window timer ensures that there is no closed window due to a lost TCP acknowledgment.

KeepAlive

KeepAlive timer controls the transmission of test messages to the remote TCP to ensure that the interface has not been broken without the local TCP's knowledge.

Examples

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 18-75 describes the specific fields in the following lines of output.

Table 18-75 show tcp Field Descriptions—Sequence Number

Field

Description

iss: 2043207208

Initial send sequence number.

snduna: 2043211083

Last send sequence number the local host sent for which it has not received an acknowledgment.

sndnxt: 2043211483

Sequence number the local host is sending next.

sndwnd: 1344

TCP window size of the remote host.

irs: 3447586816

rcvnxt: 3447586900

Last receive sequence number the local host has acknowledged.

rcvwnd: 2144

Local host's TCP window size.

delrcvwnd: 83

Delayed receive window—The data the local host has read from the connection but has not yet subtracted from the receive window that 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.

Examples

The following lines of output display values that the local host uses to track transmission times so that TCP can adjust to the network it is using.
