The * | <device-id> parameter specifies the device ID. If you enter *, the detailed updates for all
neighbor devices are displayed. If you enter a specific device ID, the update for that device is
displayed. For information about the display, refer to
Table 181 on page 1108.
Displaying FDP information for an interface
To display FDP information for an interface, enter a command such as the following.
This example shows information for Ethernet port 2/3. The port sends FDP updates every 5
seconds. Neighbors that receive the updates can hold them for up to 180 seconds before
discarding them.
Syntax: show fdp interface [ethernet <slot>/<portnum>]
The ethernet <slot>/<portnum> parameter lists the information only for the specified interface.
Displaying FDP and CDP statistics
To display FDP and CDP packet statistics, enter the following command.
Syntax: show fdp traffic
Clearing FDP and CDP information
You can clear the following FDP and CDP information:
• Information received in FDP and CDP updates
• FDP and CDP statistics
The same commands clear information for both FDP and CDP.
Clearing FDP and CDP neighbor information
To clear the information received in FDP and CDP updates from neighboring devices, enter the
following command.
BigIron RX# clear fdp table
Syntax: clear fdp table
NOTE
This command clears all the updates for FDP and CDP.
