Symptom:
Port security failed when configuring secure MAC addresses on an irrelevant port. When Port
Security is configured on two interfaces P1 & P2, and secure MAC addresses M1 & M2are
configured on interfaces P1 & P2 respectively, P1 should only allow packets with source MAC
address M1 and P2 should only allow M2. But if a packet with secure MAC address M1 ingresses
port P1, then the switch treats it like a station movement and allows the packet to be switched.

Workaround:
Cisco Systems recommends that when station movement takes place, the MAC addresses associated
with the port should be cleared in the switch's tables before moving them to another port.

A Cisco router that is running Cisco IOS Release 12.0(17)S and later 12.0 S releases may reset if
Frame Relay has been incorrectly configured. If you apply the same data link control (DLC) value
on an interface and on its subinterface twice in a row, the router may reset.
