[afnog] Difference between mac address on interface and mac address in the arp table

[Christian M]

It's a physical interface. but as you saw on the ARP table I sent earlier, the same MAC address appears also on other L3 physical interface. Is this normal or the should pick up the MAC address on the interface?

    That's fine. SVI's in Cisco switches having the same MAC address is
    normal. It is taken from VLAN 1.

    

    For the link facing the 4500 switch, that IP address is on the
    physical interface, not an SVI, yes?

    

    Mark.
