show cable-diagnostics prbs

To display the PBRS cable diagnostics test results, use the show cable-diagnostics prbs command.

show cable-diagnostics prbs {interface {interface interface-number}}

12.1(19)E

Support for this command was introduced on the Catalyst 6500 series switches.


Usage Guidelines

The show cable-diagnostics prbs command is supported on the 1-port 10GBASE-E serial 10-Gigabit Ethernet module (WS-X6502-10GE) only.

You can view the PRBS error counters only while the PRBS test is in progress. If the PRBS test has stopped running, N/A is displayed in the Error Counter field.

The PRBS error counter measures the reliability of the cable. The error counter range is 0 to 255. A value of 0 signifies a perfect link connection. A value of 255 signifies that the port is faulty or not connected or that there is no communication through the link. If the counter does not remain at zero for a predetermined length of time, the link is faulty. For example, for a baud error rate (BER) of 10^-12, the counter should remain at zero for 100 seconds.

Each time you access the PRBS counter by entering the show cable-diagnostics prbs command, the PRBS error counter value is reset to 0, and the counter begins to accumulate errors again.


Note The PRBS counter is a "read and clear" register. The first reading in a sequence is usually unreliable and serves primarily to purge the counter; successive readings are accurate.


You must start the PRBS test on both ends of the cable and then read the error counter. If you start one end and read the error counter, a nonzero value counter is displayed, and a false alarm is generated.

Table 2-22 describes the fields in the show cable-diagnostics prbs command output.

Support for this command on the Catalyst 6500 series switches was extended to the 12.1 E release.

12.1(5c)EX

This command was modified to include the switching-clock keyword.


Usage Guidelines

If you enter the switching-clock keywords, the system displays whether switching of the redundant clock sources on the backplane is allowed if the active clock source fails.

The Catalyst 6500 series switch chassis has either 64 or 1024 MAC addresses available to support software features like STP. You can enter the show catalyst6000 chassis-mac-address command to view the MAC address range on your chassis.

This example shows how to display chassis MAC address ranges and the current and peak traffic meter readings:

Router> show catalyst6000 all
  chassis MAC addresses: 1024 addresses from 00d0.004c.1800 to 00d0.004c.1c00
  traffic meter = 0%   peak = 0%  at  09:57:58 UTC Mon Nov 6 2000
  switching-clock: clock switchover and system reset is allowed

show dot1q-tunnel

To display a list of dot1q tunnel-enabled ports, use the show dot1q-tunnel command.

show dot1q-tunnel [{interface interface interface-number}]

Syntax Description

interface interface

(Optional) Specifies the interface type; possible valid values are ethernet, fastethernet, gigabitethernet, tengigabitethernet, port-channel, and ge-wan.

interface-number

Interface number; see the "Usage Guidelines" section for valid values.


Defaults

This command has no default settings.

Command Modes

EXEC

Command History

Release
Modification

12.1(11b)EX

Support for this command was introduced on the Catalyst 6500 series switches.

12.1(13)E

Support for this command on the Catalyst 6500 series switches was extended to the 12.1 E release.


Usage Guidelines

If you do not enter any keywords, the dot1q tunnel ports for all interfaces are displayed.

The interface-number argument designates the module and port number for the ethernet, fastethernet, gigabitethernet, tengigabitethernet, and ge-wan keywords. Valid values depend on the chassis and module used. For example, if you have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the slot number are from 2 to 13 and valid values for the port number are from 1 to 48.

The interface-number argument designates the port channel number for the port-channel keyword. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.

Examples

This example shows how to display dot1q tunneling status for a port channel:

Router> show dot1q-tunnel interface port-channel 10 
Interface 
--------- 
Po10

This display indicates that the port is up and has one dot1q tunnel configured on it.

12.1(13)E

Support for this command was introduced on the Catalyst 6500 series switches.


Usage Guidelines

When entering the show dot1x statistics command, you must enter interface interface interface-number for the command to perform correctly.

The interface-number argument designates the module and port number for the ethernet, fastethernet, gigabitethernet, tengigabitethernet, and ge-wan keywords. Valid values depend on the chassis and module used. For example, if you have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the slot number are from 2 to 13 and valid values for the port number are from 1 to 48.
