When my IP phone boots up on this port the MAC address of the phone shows up in vlan 1 the native vlan which also is currently used for DHCP until DHCP devices are transitioned to vlan 6. The phone grabs an IP address in vlan 1. After 2 minutes or so the MAC address will also appear on the voice vlan when displaying the mac address on the port. After this occurs then the phone releases the IP address it got in vlan 1, grabs an IP address in the voice vlan and displays an extension.
I take the phone and plug into a Catalyst 3560 and the mac address of the phone shows up on the switch port it shows up in the voice vlan and the phone is ready to use in under 60 seconds.
Here's a switchport configuration on the 6513 where I plug in the test phone where the mac of the phone shows in vlan 1 then after two minutes will show up in the voice vlan.
CDP is enabled on the 6513.
Any suggestions on eliminating this behavior?
