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

[Christian M]

Hello Mark,the ADM are YukYung (less known), Tejas and ECI.
We believe the first one was the main source of the problem.
Apologies for delayed response.

    Hi Christian.

      

      Thanks for the update.

      

      Are you able to provide more detail on which vendor this ADM is,
      for those who may be looking at something similar?

      

      Mark.

      Hello,
        this is to give an update on this issue.
        In the end, the ADM were not fully inter-operable on
          Ethernet over SDH, we decided to use pure SDH.
        

        
        Thank you Mark for your support.

            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?

                  There are 6 SVI and 12 L3 interfaces
                    and they are share the same MAC address
                    (0024.97d2.bf00)

                  
                
                

                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.
