Which is the difference between Operational VLAN Id & Admin. VLAN id in ip phone 7940?
Who controls it?
The switch or the Call Manager?
Can the modification of this parameter affect the attached pc?
Thanks in advance!
Best explanation I could find was here (http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/sip7960/sipadm2/maintain.htm#xtocid151964), then scroll down a bit. Even though it is for a SIP phone I think it is still relevant.
Operational VLAN Id
Both are tagged. It's a matter of which one the phone uses. If you can't run CDP and therefore assign an Admin VLAN manually, the phone will use the Admin VLAN. If the phone has an Admin VLAN manually assigned but also learns of one via CDP/LLDP, then it will use the learned VLAN as displayed in the "Operational VLAN ID" field.
