The Cisco 7920 should have registered with the Cisco CallManager server.

Note: The IP address of the phone is now 10.21.8.22. This is from the IP subnet 10.21.8.0 that is assigned to VLAN2. In the previous configuration, before the VLAN was created, it was using IP address 10.21.7.20.

You should be able to place calls between the Cisco 7920 and your other IP Phone.

Configuring 802.1Q Trunking on the Catalyst 2924 XL

This subtask provides the partial configurations required to establish trunk ports on a Catalyst 2924 XL. The same commands are supported on the Cisco Catalyst 3524 PWR XL Switch.

If you would like to review the concepts related to the establishment of trunk ports on a Catalyst 2924 XL, refer to Configuring VLANs.

The Catalyst 2924 XL uses VLAN1, by default, as the native VLAN for untagged 802.1Q frames. The Cisco Aironet 1200 AP is also using VLAN1 as the native VLAN for untagged 802.1Q frames.

The Cisco Aironet 1200 AP communicates with other wireless infrastructure devices, such as bridges and repeaters, over the native VLAN. Refer to the Wireless Virtual LAN Deployment Guide for the Cisco Aironet 1200 Series, for more information on this subject. In addition, the Cisco Aironet 1200 AP sends all Remote Authentication Dial−In User Service (RADIUS) AAA traffic over the native VLAN.
