2910al not learning mac addresses

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

Re: 2910al not learning mac addresses

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?
