Viewing Multicast VLAN Policies

You can view the current multicast VLAN policies and their status using the vimcrl command.
Type vimcrl and a Policy Configuration Table displays similar to the following:
VLAN VLAN Rule Rule Rule Rule
Group : Id Num Type Status Definition
-------------------------------------------------------------------------------------------------------------------------------
3: 5 1 PORT RULE Disabled 2/7/Brg/1
3: 5 2 MCAST Disabled 072467:0034ab
3: 22 1 PORT RULE Enabled 2/7/Brg/1
3: 22 2 MCAST Enabled 080027:0135de1
3: 23 1 PORT RULE Enabled 2/7/Brg/1
3: 23 2 MCAST Enabled 050034:000017
3: 24 1 MAC RULE Enabled 082008:003002
082009:803728
3: 24 2 MCAST Enabled 053967:0126af5
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.
Rule Num. The number for this rule within the multicast VLAN definition. Each rule defined for
a multicast VLAN is numbered sequentially in the order of creation. The rule number is
needed when you want to modify or delete a rule definition.
Rule Type. The type of multicast VLAN rule. For multicast VLANs, the rule type can be PORT
RULE, MAC RULE, or MULICAST RULE. Each multicast VLAN by definition will contain a multi-
cast rule. The multicast rule defines the multicast address. In addition, the multicast VLAN
contains either a Port-based rule, MAC address rule, or both a Port and MAC address rule. The
Port and MAC address rules define the recipients of multicast traffic.
Rule Status. Indicates whether the rule for this row is Enabled or Disabled. If the rule is
enabled, then the switch is using the rule definition to determine multicast traffic flooding. If
Disabled, then the switch is not using this rule to regulate multicast traffic flow. Note that this
Rule Status is different from the Admin Status for the multicast VLAN since it controls only this
specific rule within this specific multicast VLAN. You can enable or disable the rule using the
modmcvl command.
Rule Definition. Details of this rule. For a Port Rule, this column lists the virtual interface for the
Port that is a recipient of the multicast traffic as
<slot>/<port>/<service>/<instance>
For example, the port defined for the first row in the table applies to the first bridge instance
on port 7 on the module in slot 2 of the switch. For a MAC address rule, this column lists the
MAC address for the recipient of the multicast traffic. For a multicast Rule, this column lists the
multicast address.
