    Hi Sumeet, It seem that you can look inside FDB. I mean "show fdb

    If you have new generation, you can use new feature of EXOS 22.2 = node-alias. You will see all identity information the mac address used. Even if staticaly configured, even if wrong configured. Z.

    'show iparp' gives ip addresses allocated in default virtual router .

    You have X460-G1 so you can't use EXOS 22.2.

    To look EXOS version:
    #show switch
    #show version images

    Just FYI - http://documentation.extremenetworks.com/release_notes/ExtremeXOS/22.2/EXOS_Release_Notes/22.2/c_nod...

    Thank you!

    Hi Sumeet, Yes, FDB will not show IP directly, but you can find VLAN. It can be usefull if client is wrong configured so it doesn't get IP and/or statically configured. As long as I know, the ARP is only works if the client is configured with IP of the right subnet, dynamically or statically. Anyway, I rather suggest to use DHCP server outside the switch. The switch can be used as DHCP relay. Linux based DHCP server log is more handy to analyze than the switch. Best regards,

    Agreed and if I'm not mistaken, you can only show the IP ARP if the switch has an IP in that same VLAN.

    You can use Extreme Management Center = NetSight with flexview available here = https://github.com/extremenetworks/Netsight-Report-Views/tree/master/FlexView/EXOS

    It is there under name "Learned MAC to IP"

    Good luck

    how to import flexview is here. Once you have the flexview in your Extreme Management Center you can OneView -> Network -> choose your devices, right click -> View -> FlexView

    Use XMC tool called compass search. And put there MAC or IP and hit the search button.
