I have a NMD-16ESW module installed on a 2851 Router . I was trying Mac-address table command on it.
I have two Vlans One for Voice and one for Data created on it.
Data Vlan : 10
I wanted to secure the interface so that no one can add other devices to the ports.
I secured the MAC address of the Voip phone and PC in Fa0/2 under vlan 1 and vlan 10.
Now my question is do i have to add the MAC address of the VOIP phone under Data vlan also.If yes WHY?
Seconldy wht will happen if I add a new PC to the fa0/2.Will that PC be able to communicate? Will that port go in error disabel state , shutting VOIP phone also.
Third . with which command I shd check the error logs.
