display multicast fast-forwarding cache
Use display multicast fast-forwarding cache to display multicast fast forwarding entries.
Syntax
In standalone mode:
display multicast [ vpn-instance vpn-instance-name ] fast-forwarding cache [ source-address | group-address ] * [ slot slot-number ]
In IRF mode:
display multicast [ vpn-instance vpn-instance-name ] fast-forwarding cache [ source-address | group-address ] * [chassis chassis-number slot slot-number ]

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays multicast fast forwarding entries on the public network.
source-address: Specifies a multicast source address.
group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays 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 multicast fast forwarding entries for the global active MPU. (In IRF mode.)

<Sysname> display multicast fast-forwarding cache Total 1 entries, 1 matched (60.1.1.200, 225.0.0.2) Status : Enabled Source port: 2001 Destination port: 2002 Protocol : 2 Flag : 0x2 Incoming interface: Vlan-interface1 List of 1 outgoing interfaces: Vlan-interface2 Status: Enabled Flag: 0x14
Table 24: Command output
Field | Description |
---|---|
Total 1 entries, 1 matched | Total number of (S, G) entries in the multicast fast forwarding table, and the total number of matching (S, G) entries. |
(60.1.1.200, 225.0.0.2) | (S, G) entry. |
Protocol | Protocol number. |
Flag | Flag of the (S, G) entry or the outgoing interface in the entry. 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 value 0x14 means that the interface has flags 0x4 and 0x10. The following flags are available for an entry:
The following flags are available for an outgoing interface:
|
Status | Status of the (S, G) entry or the outgoing interface:
|
Incoming interface | Incoming interface of the (S, G) entry. |
List of 1 outgoing interfaces | Outgoing interface list of the (S, G) entry. |
