The address threshold for a bridge is the reporting threshold for the total 
number of Ethernet addresses known to the system. When this threshold is 
reached, the SNMP trap addressThresholdEvent is generated. 

The range of valid values for this parameter is between 1 and the address 
table size + 1. Setting the address threshold to one greater than the address 
table size disables the generation of addressThresholdEvents because the 
limit will never be reached. The default value is 8000.

To set the address threshold:

1 From the top level of the Administration Console, enter:

2 Enter the value of the threshold.

The bridge aging time is the maximum period (in seconds) for aging out 
dynamically learned forwarding information. This parameter allows you to 
configure the system to age addresses in a timely manner, without 
increasing packet flooding.

The values can range from 10 to 32,267 seconds. The default value is 300 
seconds, which is 5 minutes.

To set the bridge aging time:

1 From the top level of the Administration Console, enter:

2 Enter the aging time value.
