Use display l2-multicast fast-forwarding cache to display Layer 2 multicast fast forwarding entries.

Syntax

In standalone mode:

display l2-multicast fast-forwarding cache [ vlan vlan-id ] [ source-address | group-address ] * [ slot slot-number ]

In IRF mode:

display l2-multicast fast-forwarding cache [ vlan vlan-id ] [ source-address | group-address ] * [ chassis chassis-number slot slot-number ]

Parameters

vlan vlan-id: Specifies a VLAN by its VLAN ID in the range of 1 to 4094.

source-address: Specifies a multicast source address. If you do not specify a multicast source, this command displays Layer 2 multicast fast forwarding entries for all multicast sources.

group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255. If you do not specify a multicast group, this command displays Layer 2 multicast fast forwarding entries for all multicast groups.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays Layer 2 multicast fast forwarding entries for the MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays Layer 2 multicast fast forwarding entries for the global active MPU. (In IRF mode.)

Table 8: Command output

Field	Description
Total 1 entries, 1 matched	Total number of (S, G) entries in the Layer 2 multicast fast forwarding table, and the total number of matching entries.
(10.1.1.2, 225.1.1.1)	(S, G) entry in the Layer 2 multicast fast forwarding table.
Protocol	Protocol number.
VLAN	VLAN ID.
Flag	Flag for the (S, G) entry or the outgoing port. This field displays one flag or the sum of multiple flags. In this example, the value 0x2 means that the entry has only one flag 0x2. The following flags are available for an entry: 0x1—The entry is created because of packets passed through between cards. 0x2—The entry is added by multicast forwarding. The following flags are available for an outgoing interface: 0x1—The port is added to the entry because of packets passed through between cards. 0x2—The port is added to an existing entry. 0x10—The port is associated with the entry. 0x20—The port is to be deleted.
Status	Status of the (S, G) entry or the outgoing port: Enabled—Available. Disabled—Unavailable.
Ingress port	Incoming port of the (S, G) entry.
List of 1 egress ports	Outgoing port list of the (S, G) entry.
