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

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

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.
