MAC aging time getting updated

[luguille]

Hello,

I just wanted to know when the Aging Time for a respective MAC address should be updated by the switch.

There is a N5K switch that reset/update the Aging Time for a MAC every 30 seconds or so. Is this normal? I guess no.

Hi,

By default the aging time for mac address is 300 seconds (5min).

My question now is, what can trigger the switch to update the MAC Aging Time?
