Managing the Address Forwarding Table

3.  Click:

■

APPLY to save your changes

■

CANCEL to restore previous settings

■

Delete All Learned Entries if you want to relearn the entire table

■

Delete Invalid Learned Entries if you want to delete all entries 
that are currently aged out.

* Note:  If you change the Hash Table Size, the switch relearns all 

addresses in that table, causing the switch to flood packets for a 
few seconds.

To manually control reconfiguration of AFT sizes using the Web Agent:

1.  In the navigation pane, expand the L2 Switching > Address 

Forwarding Table folders, and then click Configuration. The Address 
Forwarding Table Configuration Web page is displayed in the content 
pane. See 

.

2.  Enter a new Auto-Sizing Utilization Threshold percentage in the 

Threshold (Util%) field, if you just want to cause the table 
reconfiguration to occur at a different level of usage efficiency. The 
default value of 40% is recommended for most applications. 

*Note: Raising the value in the Threshold (Util%) field might 

cause the table to be relearned more frequently, and makes 
address space usage more efficient.

To manually control reconfiguration of AFT sizes using the CLI, enter the 
following command in Enable/Configure mode:

(configure)# 

The AFT can hold 24,000 entries on each switch. The switch Web Agent 
provides a utility that allows you to filter which addresses it displays, 
making the list more manageable. Multiple criteria can be selected to 
produce a sophisticated filter. The parameters are treated as “ands,” 
meaning that displayed addresses must meet all selected criteria.

You can search the AFT using the Web Agent or the CLI.
