16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series
Disabling Per-Port Storm-Control
Beginning in privileged EXEC mode, follow these steps to disable per-port storm-control:
Command
Step 1 configure terminal
Step 2 interface interface
Step 3
no storm-control {broadcast |
multicast | unicast} level
Step 4
no storm-control action shutdown
Step 5
end
Step 6 show storm-control {broadcast |
multicast | unicast}
Configuring Separate Voice and Data Subnets
For ease of network administration and increased scalability, network managers can configure the
Ethernet switch network module 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 Ethernet switch network module provides the performance and intelligent services of
Cisco IOS software for branch office applications. The Ethernet switch network module 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.
Note Refer to the Cisco AVVID QoS Design Guide for more information on how to implement end-to-end QoS
as you deploy Cisco AVVID solutions.
To automatically configure Cisco IP phones to send voice traffic on the voice VLAN ID (VVID) on a
per-port basis (see the
beginning in global configuration mode:
Command
Step 1
Router(config)# enable
Step 2
Router(config)# configure terminal
Step 3
Router(config)# interface interface
Purpose
Enters global configuration mode.
Enters interface configuration mode, and enter the port to configure.
Disables per-port storm control.
Disables the specified storm control action.
Returns to privileged EXEC mode.
Verifies your entries.
"Voice Traffic and VVID" section on page
Purpose
Enters the privileged EXEC mode. A preset password may be
required to enter this mode.
Enters global configuration mode.
Enters the interface configuration mode and the port to be
configured (for example, interface fa5/1).
