Viewing voice VLAN configurations
You can view the configuration of a voice VLAN for a particular port or for all ports.
To view the voice VLAN configuration for a port, specify the port number with the show voice-vlan
command. The following example shows the command output results.
The following example shows the message that appears when the port does not have a configured
voice VLAN.
To view the voice VLAN for all ports, use the show voice-vlan command. The following example
shows the command output results.
Syntax: show voice-vlan [ethernet <port>]
Specify the port variable in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• FESX compact switches – portnum
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both.
Port flap dampening configuration
Port Flap Dampening increases the resilience and availability of the network by limiting the number
of port state transitions on an interface.
If the port link state toggles from up to down for a specified number of times within a specified
period, the interface is physically disabled for the specified wait period. Once the wait period
expires, the port link state is re-enabled. However, if the wait period is set to zero (0) seconds, the
port link state will remain disabled until it is manually re-enabled.
