2910al not learning mac addresses

    Posted Jul 24, 2013 11:43 AM

    we've installed a 2910-48g al. Problem is the switch doesn't learn mac-addresses of connected devices (instead the mac address of the gateway is stored for all ip's and the clients return ip address conflict because of the same mac address).

    Boow-Rom: 14.06

    Software: tested W.14.70, W.15.08.0012 and W.15.12.0006

    IP addresses don't appear in the mac-address table, where learnt mac-addresses are stored.

    IP addresses appear in the ARP table, which your switch doesn't use unless you have it configured as a router.

     

    Maybe attach the switch config first, so we can have a look?
