Viewing Multicast VLANs

You can view the current status of all multicast VLANs 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.
