It's not a MAC address, it's a client identifier. And IOS by default chooses a text string as client identifier. In your case it's: "cisco-0050.56a8.4a2b-Gi0/0" > Anything to configure at Cisco clients to have proper MAC in binding > database ? The above example is completely proper. I'm not aware of any method for making IOS not use a client identifier, but you can change the identifier it sends via e.g. "ip dhcp client client-id ..." interface command. -- Peter _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
