Managing the Address Forwarding Table
It is highly recommended the default of 40% not be changed. The 
affects of varying the Threshold (Util%) are as follows:
Increasing Threshold: Gives better memory utilization at the 
expense of more frequent flushing, flooding, and relearning.
Decreasing Threshold: Gives less efficient memory utilization but 
does not flush, flood and relearn as often.
Total Entries, Address Memory, Age and Super-
Age Timers
Overview
You can see the Total Entries and Address Memory. You can configure 
address age, auto-sizing threshold, and Super Age timers. See 
Total Entries
Display how many address entries are contained in the table.
Address Memory
Displays how much address memory is currently being used, the amount of 
memory still available, and the largest contiguous block of memory that can 
exist.
Address Age and 
Super Age timers
Address Age Time - defines the length of time addresses remain 
active in the address forwarding table.
Super Age Time - defines how long inactive addresses are stored in 
the address forwarding table before being deleted.
Configuring the AGE and Super Age Timers 
Web Agent 
Procedure
You can configure the Age Timer and Super Age Timer by using either the 
Web Agent or the CLI. 
Enter a value in the Age Time field. Aged out addresses become invalid 
until the switch sees another packet with the aged out entry’s source 
address.The standards-recommended default is 300 seconds.
* Note:  If you have ATM Uplink Modules in the chassis and you set the 
Age Timer value to less than 30 seconds, you must change the 
Flush MAC Timer on each ATM Uplink module to be less 
than or equal to the new Age Timer value.
