To configure the aging time for dynamic FDB entries, use
the following command:.
configure
fdb agingtime seconds
If the aging time is set to 0, all aging entries
in the database are defined as static, nonaging entries. This means the entries will not
age out, but non-permanent static entries can be deleted if the switch is reset.
To display the aging time, use the following
command:.
show fdb
Note
On BlackDiamond 8900 xl-series, Summit X480,
X460-G2, 100G4X, and 100G4X-xl switches, FDB entries are aged in hardware, the aging
time is always displayed as 000, and the h flag is set for entries that are hardware
aged.
