I'm currently allowing only one mac address on my port, my config look like this

set port security 1/7 enable age 10 maximum 1 shutdown

I expect that if I unplug a pc from port 1/7 and plug this same pc back in port 1/7 before the 10 min againg timer expires, system should not disable my port. But it doesn't happen that way, port 1/7 goes into shut down mode as soon as i plug in the same pc. Any thoughts?

once you plugged in the pc back again, check the numbers of mac-address on port 1/7, how many? the switch might still store the mac-address up to 10 minutes after you unplugged, then once plugged in back, the switch thinks that there are 2 mac-address on that port.

show logging

to check the violation logs.
