In the following configurations, the powerinline command is set to auto by
default.
For ease of network administration and increased scalability, network managers
can configure the Catalyst 4224 to support Cisco IP phones such that the voice
and data traffic reside on separate subnets. You should always use separate
VLANs when you are able to segment the existing IP address space of your branch
office.
User priority bits in the 802.1p portion of the 802.1Q standard header are used to
provide prioritization in Ethernet switches. This is a vital component in designing
Cisco IP Telephony networks.
The Catalyst 4224 provides the performance and intelligent services of Cisco IOS
software for branch office applications. The Catalyst 4224 can identify user
applications—such as voice or multicast video—and classify traffic with the
appropriate priority levels. QoS policies are enforced using Layer 2 and 3
information such as 802.1p, IP precedence, and DSCP.
Refer to the Cisco AVVID QoS Design Guide for more information on how to
implement end-to-end QoS as you deploy Cisco IP Telephony solutions.
The following exit procedure shows how to automatically configure Cisco IP
phones to send voice traffic on the voice VLAN ID (VVID). (See the
Traffic and VVID" section on page
