I am facing a VLAN issue in IP Phones. We have a default vlan, data vlan and voice vlan. When I configure the phones for data and voice vlans, the IP Phones takes the correct IP address from voice dhcp but it does not get register. It gets correct default router, TFTP, DHCP and dns. But it is not getting registered. I use the following commands to configure both data and voice vlan after creating the respective vlans. But when these vlans are removed the phones gets registered. I am configuring these commands in a L2 3750 cisco switch. We also have a 4900 L3 switch.
interface gigabitethernet 1/0/8
switchport mode access
switchport access vlan 10
switchport voice vlan 100
But when I went through the CME admin guide it shows a different set of commands instead of the above given commands. The conf in cme admin guide is as follows.
