Cisco Systems 7600 Series Manual De Usuario

When configuring unicast flood protection, note the following syntax information:

Use the limit keyword to specify the unicast floods on a per source MAC address and per VLAN 
basis; valid values are from 1 to 4000 floods per second (fps).

Use the filter keyword to specify how long to filter unicast flood traffic; valid values are from 1 to 
34560 minutes.

Use the alert keyword to configure the system to send an alert message when frames of unicast 
floods exceed the flood rate limit.

Use the shutdown keyword to configure the system to shut down the ingress port generating the 
floods when frames of unicast floods exceed the flood rate limit. 

This example shows how to configure the system to filter unicast flood traffic for 5 minutes and set the 
flood rate limit to 3000 fps:

Router(config)# mac-address-table unicast-flood limit 3 vlan 100 filter 5

Router # show mac-address-table unicast-flood

Unicast Flood Protection status: enabled

Configuration:

 vlan      Kfps         action       timeout

------+----------+-----------------+----------

  100          3             filter         5

Mac filters:

 No.   vlan   souce mac addr.           installed on           time left (mm:ss)

Router(config)#

When you configure MAC move notification, a message is generated when a MAC address moves from 
one port to another. 

The MAC address move notification feature does not generate a notification when a new MAC address 
is added to the CAM or when a MAC address is removed from the CAM.

To configure MAC move notification, perform this task:

Router(config)# [no] mac-address-table 

 

Enables MAC move notification globally. 

Router# show mac-address-table notification 

 

Displays MAC move notification information.
