we have server with 2 NICs connect to differrent switches (CAT6), server using HP build-in software to run network teaming. and we also configured port security on the switch port and only allow 1 mac address.
I also checked the server teaming configuration, 2 NICs original mac adress are :AAAAAAAAAAAA and BBBBBBBBBB, after binding to teaming, the virtual MAC address is BBBBBBBBBBBBB.
it was working properly at first, until I plug out one connection, which happen to be the active connection, the server got disconnected form the network, and the switch returned me the error msg:"
%PORT_SECURITY-SP-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address AAAAAAAAAAAA on port GigabitEthernet3/20."
when i checked the mac address table using command "show mac-address-table interface gX/XX", gX/XX is the port connect to the NIC with MAC AAAAAAAAAAAA. I got 2 record, one is static and ther other is dynamic:
* 90 AAAAAAAAAAAA static Yes - Gi3/20
* 90 BBBBBBBBBBBB dynamic Yes 45 Gi3/20
i did not configure any "static" mac on the switch, and how come there is static mac address in the record? If I can remove that static record, we can slove that issue. I have checked the cisco web site and foum topic, some posts also raised the same issue but no solution yet.
I also post my port configuration for your infomation:
thanks for your reply, I think you are still not clear about my problem:
of course i can solve the problem by setting the maximum number of MAC addresses to 2, but i don't think it is the good way. Because I saw there are 2 MAC addresses entries in the switch: 1 is static and 1 is dynsmic, if i can remove the static MAC entry, problem can be sloved.
But i don't know why there is a static entry and how to remove it.
