Parameters
time-value: Specifies the aging timer in minutes for secure MAC addresses. The value is in the range
of 0 to 129600. To disable the aging timer, set the timer to 0.
Usage guidelines
The timer applies to all sticky secure MAC addresses and those automatically learned by a port.
A short aging time improves port access security and port resource utility but affects online user
stability. Set an appropriate secure MAC address aging timer according to your device performance
and the network environment.
Examples
# Set the secure MAC aging timer to 30 minutes.
