Chapter 26 Diagnosing Switch Problems; Verifying The Vlan Configuration; Understanding Port Output - Alcatel-Lucent OmniSwitch AOS Release 7 Manual

Configuring VLANs

Verifying the VLAN Configuration

To display information about the VLAN configuration for a single switch use the show commands listed
below:
show vlan
show vlan members
show ip interface

Understanding Port Output

Each line of the show vlan members output display corresponds to a single VLAN port association
(VPA). In addition to showing the VLAN ID and slot/port number, the VPA type and current status of
each association are also provided.
The VPA type indicates that one of the following methods was used to create the VPA:
Type Description
default The port was statically assigned to the VLAN using the
untagged
VLAN.
qtagged The port was statically assigned to the VLAN using the
tagged
tagged port.
mirror The port is assigned to the VLAN because it is configured to mirror another
port that is assigned to the same VLAN. For more information about the
Port Mirroring feature, see
The VPA status indicates one of the following:
Status Description
inactive Port is not active (administratively disabled, down, or nothing connected to
the port) for the VPA.
blocking Port is active, but not forwarding traffic for the VPA.
forwarding Port is forwarding all traffic for the VPA.
filtering Mobile port traffic is filtered for the VPA; only traffic received on the port
that matches VLAN rules is forwarded. Occurs when a mobile port's VLAN
is administratively disabled or the port's default VLAN status is disabled.
Does not apply to fixed ports.
The following example displays VPA information for all ports in VLAN 200:
