I have a peculiar issue with port security. Basically what's happening is this. I have User A and User B who can not communicate with each other (icmp, ip, everything) but have no problems with anyone else. We're all on the same vlan and on the same switch. Port security is enabled with the same settings on all machines. If I were to disable port-security on one of the users, then both users can ping/connect each other. What's wierd is I don't have to disable on both. No one else seems ot have this issue. However this has happened once more after and the only similarity between them all is that they were all from Dell Optiplex 620s.
I haven't tried moving them to other ports and no firewalls are installed on the PCs. However if I toggle port-security on one of the PCs you can definitely see the difference (turned on it can not be pinged by this one machine nor vice versa).
Here's a sample config of what I use:
no service pad
service timestamps debug uptime
service timestamps log datetime
enable secret 5 blah
enable password 7 blah
username blah password blah
aaa authentication login default group tacacs+ local
aaa authorization config-commands
aaa authorization exec default group tacacs+ local
aaa authorization commands 15 default group tacacs+ none
aaa accounting auth-proxy default start-stop group tacacs+
Did you try to remove it one-by-one and test what command casue the problem ? And, can confirm the aging time is 1 mins ? I suggest to try to remove "violation" first and test then remove aging and test again.
And, is this port connected w/ more than 2 PC at the same time, you configure maximum 2 and it limited 2 MAC address only.
