They are saying... Check the switch configuration file to determine the source of these packets on the specified port and take corrective action to fix them at the source
And force the switch to re-learn the MAC addresses correctly
Can you please tell me what configuration i need to check to force the switch to learn correct MAC address.
The switch reports the %C4K_L2MAN-5-ROUTERMACADDRESSRXASSOURCE:Packet received with my own MAC address ( [mac-addr] ) as source on port [char] in vlan [dec] error message.
A packet was received with the MAC address of the switch as the source address. This MAC was not learned as a valid source address, which suggests that there is a configuration problem. This message is rate-limited and is displayed only for the first such packet received on any interface or VLAN. Subsequent messages display a cumulative count of all such packets received in a given interval on all interfaces in any VLAN.
Complete these steps to resolve the issue:
Clear the MAC address table and force the switch to re-learn the MAC addresses correctly.

Check the switch configuration file to determine the source of these packets on the specified port and take corrective action to fix them at the source. This usually signifies a loop in your configuration.
