show mac

Use the show mac command to display MAC counters.

Syntax Description

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 4000 family switches
Catalyst 2926G series switches
Catalyst 2948G switch

Command Type

Switch command.

Command Mode

Normal.

Usage Guideline

The Catalyst 2948G is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter mod_num 1/N, an error message will be displayed.

Example

This example shows how to display MAC information for port 3 on module 4:

show module

Use the show module command to display module status and information.

Syntax Description

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 4000 family switches
Catalyst 2926G series switches
Catalyst 2948G switch

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

If you remove a module and replace it with a different type module, a message appears in the show module display that states that the module configuration is inconsistent with the current module type. To clear the message, you can either enter the clear config mod_num command for the module or set different parameters for the new module.

For Supervisor Engine III modules, the show module command displays the supervisor engine's module number but appends the uplink daughtercard's module type and information.

For Catalyst 4000 family switches, the show module command displays the supervisor engine as having "1" slot.

For Catalyst 4000 family switches, in the show module command display, the combination of the 32-port module (WS-X4502) and 4-port 100FX daughtercard results in an entry that reads 36 ports. If the uplink daughtercard is not installed, only ports 1 through 32 are listed.

Although me1 resides on the supervisor engine module for the Catalyst 4000 family and 2948G switches, me1 port information is not displayed by the show module or show port CLI commands.

For Catalyst 2948G switch, the show module command displays two modules, a Switching Supervisor and an Ethernet module. Both modules are internal to the box and are not removable. The show module command also displays both modules as having "1" slot.

This example shows how to display status and information for all modules on the switch (Catalyst 5000 family and 2926G series switches):

Example

This example shows how to display the current NTP status:

Console> show ntp
Current time: Thu Jan 15 1999, 11:19:03 pst
Timezone: 'pst', offset from UTC is -8 hours
Summertime: 'pst', enabled
Last NTP update:
Broadcast client mode: enabled
Broadcast delay: 3000 microseconds
Client mode: disabled
Authentication: enabled
 
NTP-Server                                Server Key
----------------------------------------  ----------
172.20.33.140                             1722033140
172.20.33.114                             1722033114
 
Console>
 

The following output appears in the show ntp command output when entered from privileged mode:

Key Number   Mode        Key String
----------   ---------   --------------------------------
1234         trusted     32423423423
