Multiple copies of the same frame from different ports on the same switch will not "corrupt the MAC table" as such, but is known as "host flapping". If STP/RSTP is doing its job correctly, then it simply should not happen, and can be regarded as a breakdown in you network topology.
Do you have a specific problem you would like to tell us about?
A vendor provided five servers with the same MAC software defined. They worked fine until I moved them to the same lan segment. Using wireshark, I seen what appears to be copies of MAC going into the switch. "show mac-address-table" had incomplete statements. This put the switch (C2950G) utility to 90%. STP/RSTP does not appear to be able to handle this situation well. Is there another layer 2 routing protocol that would handle this scenario better?
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
