Transparent ?can create, modify, and delete VLANs, but they are not propagated to any other switch. This device still forwards VTP updates received on its trunk ports.
You can configure VTP in VLAN configuration mode, as well as global configuration. These examples show both modes of configuration. They also show configuring a VTP domain name and password, both of which need to be identical on every other switch in the domain.
Configuration of a client or transparent switch is identical to the config above, except you specify client or transparent in place of server.
Voice VLAN
Voice VLANs are VLANs that are for the sole purpose of carrying Voice over IP traffic. They are their own broadcast domain, and the switch can perform QoS on both Voice traffic and the other IP traffic coming into the port. In typical Voice VLAN configuration you plug your PC into the Cisco 7960 IP phone, and then plug your phone into a switchport. The IP Phone configures a trunk to the switch and sends the Voice traffic tagged with both an 802.1q header and a priority of 5, or 802.1q header with a priority of 5. The IP traffic that is forwarded from the PC goes to the switch untagged or on the 搉ative VLAN?
