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
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.
