Hi all I am configuring a Cat 2960 port for connecting a VOIP phone, authenticated by MAB. On connecting the phone, I get the port authenticated and assigned to the correct VLAN, with LLDP-MED advertising the correct voice vlan. However, I then see no traffic from the phone on the switch. I can see the MAC address of the phone is learned in the right VLANs, but the mac address is showing as 'Drop', which normally means the address is statically configured to be blocked. There is no static mac address table blocking configured on the switch. Can anyone suggest why this is happening?
