Cisco HWIC-4ESW and HWIC-D-9ESW EtherSwitch Interface Cards
Monitoring and Maintaining the Network
To monitor and maintain the network, use one or more of the following privileged EXEC commands.
Command
clear bridge bridge-group
show bridge [bridge-group]
show bridge [bridge-group] [interface-id] [address]
[group] [verbose]
Configuring Separate Voice and Data Subnets
For ease of network administration and increased scalability, network managers can configure the
HWICs 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 AVVID networks.
The HWICs provides the performance and intelligent services of Cisco IOS software for branch office
applications. The HWICs can identify user applications—such as voice or multicast video—and classify
traffic with the appropriate priority levels.
Refer to the Cisco AVVID QoS Design Guide for more information on how to implement end-to-end QoS
Note
as you deploy Cisco AVVID solutions.
Follow these steps to automatically configure Cisco IP phones to send voice traffic on the voice VLAN
ID (VVID) on a per-port basis (see the
