DETAILED STEPS
To reenable spanning tree on the interface, use the no bridge-group bridge-group spanning-disabled
interface configuration command.
Monitoring and Maintaining the Network
To monitor and maintain the network, use one or more of the following privileged EXEC commands.
Configuring Separate Voice and Data Subnets
For ease of network administration and increased scalability, network managers can configure the
EtherSwitch HWIC 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 EtherSwitch HWIC provides the performance and intelligent services of Cisco IOS software for
branch office applications. The EtherSwitch HWIC can identify user applications—such as voice or
multicast video—and classify traffic with the appropriate priority levels.
Command Purpose
Step 1
configure terminal
Enters global configuration mode.
Step 2
interface interface-id
Enters interface configuration mode, and specify the interface ID.
Step 3
bridge-group bridge-group
spanning-disabled
Disables spanning tree on the interface.
For bridge-group, specify the bridge group number. The range is 1
to 255.
Step 4
end
Returns to privileged EXEC mode.
Step 5
show running-config
Verifies your entry.
Step 6
copy running-config startup-config
(Optional) Saves your entry in the configuration file.
Command Purpose
clear bridge bridge-group
Removes any learned entries from the forwarding database and
clears the transmit and receive counts for any statically
configured entries.
show bridge [ bridge-group ]
Displays details about the bridge group.
show bridge [ bridge-group ][ interface-id ][ address ]
[group] [verbose]
Displays classes of entries in the bridge forwarding database.
