configure fdb agingtime

configure fdb agingtime seconds

Description

Configures the FDB aging time for dynamic entries.

Syntax Description

agingtime If agingtime is set to 0, all aging entries in the database are defined as static, nonaging entries.
seconds Specifies the FDB aging time, in seconds. A value of 0 indicates that the entry should never be aged out. All other platforms support the value 0 (no aging) and a range of 15 to 1,000,000 seconds.

Default

300.

Usage Guidelines

If the aging time is set to 0 (zero), all dynamic entries in the database become static, nonaging entries. This means that they do not age out, but non-permanent static entries can be deleted if the switch is reset.

The software flushes the FDB table once the aging timeout parameter is reached, even if the switch is running traffic and populating addresses in the FDB table.

Example

The following example sets the FDB aging time to 3,000 seconds:

# configure fdb agingtime 3000
