Viewing Multicast VLANs
You can view the current status of all multicast VLAN s in the switch using the mcvl command.
Type mcvl and a table similar to the following displays:
VLAN VLAN VLAN Admin Operational
Group : Id Description Status Status
-------------------------------------------------------------------------------------------------------------------------------
3: 5 MVLAN 5 Enabled Active
3: 11 MVLAN 11 Enabled Inactive
3: 12 MVLAN 12 Enabled Inactive
3: 22 MVLAN 22 Enabled Active
3: 23 MVLAN 23 Enabled Active
3: 24 MVLAN 24 Enabled Inactive
3: 25 MVLAN 25 Enabled Inactive
3: 26 MVLAN 26 Enabled Inactive
3: 27 MVLAN 27 Enabled Inactive
3: 31 MVLAN 31 Enabled Inactive
3: 32 MVLAN 32 Enabled Inactive
VLAN Group. The Group to which this multicast VLAN is assigned. The Group is specified
when first creating a multicast VLAN .
VLAN ID . An identification number that you assigned when you created this multicast VLAN .
VLAN Description. A textual description that you entered to describe a multicast VLAN when
you created or modified it through crmcvl or modmcvl . This description is limited to 30 charac-
ters.
Admin Status. A multicast VLAN can be enabled or disabled. You enable or disable a multicast
VLAN when you create or modify it. If the multicast VLAN is enabled, AutoTracker floods
multicast traffic to the recipients you specified when setting up the multicast VLAN . If the
multicast VLAN is disabled, the multicast traffic is not flooded as you specified; however, the
parameters you set up for the multicast VLAN are saved.
Oper Status. The multicast VLAN is shown as active or inactive. In order for an enabled multi-
cast VLAN to become “active” it must be able to assign a switch port to the multicast VLAN . If
the port rule is used for a multicast VLAN, then the multicast VLAN automatically becomes
active. If you defined multicast traffic recipients by MAC address only, then a frame destined
for a defined MAC address must first be received by a switch port before the multicast
VLAN is
active. An active multicast VLAN requires the following:
• Admin Status must be enabled.
• A port must be assigned to the multicast VLAN through either a port-based rule or by a
device transmitting data that matches the multicast VLAN policy.
