Parameters
aging seconds
: Sets an aging timer in seconds for dynamic MAC address entries,in the range 10 to
86400.
no-aging
: Sets dynamic MAC address entries not to age.
Description
Use the
mac-address timer
command to configure the aging timer for dynamic MAC address entries.
Use the
undo mac-address timer
command to restore the default.
By default the default aging timer is 300 seconds.
Set the aging timer appropriately: a long aging interval may cause the MAC address table to retain
outdated entries and fail to accommodate the latest network changes; a short interval may result in
removal of valid entries and hence unnecessary broadcasts which may affect device performance.
Examples
# Set the aging timer for dynamic MAC address entries to 500 seconds.
