Use display multicast-vlan group to display information about multicast groups in multicast VLANs.

Syntax

In standalone mode:

display multicast-vlan group [ source-address | group-address | slot slot-number | verbose | vlan vlan-id ] *

In IRF mode:

display multicast-vlan group [ source-address | group-address | chassis chassis-number slot slot-number | verbose | vlan vlan-id ] *

Parameters

source-address: Specifies a multicast source by its IP address. If you do not specify a multicast source, this command displays information about multicast groups for all multicast sources in multicast VLANs.

group-address: Specifies a multicast group by its IP 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 information for all multicast groups in multicast VLANs.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays information about multicast groups in multicast VLANs 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 information about multicast groups in multicast VLANs for the global active MPU. (In IRF mode.)

verbose: Displays detailed information.

vlan vlan-id: Specifies a multicast VLAN by its VLAN ID in the range of 1 to 4094. If you do not specify a multicast VLAN, this command displays information about multicast groups for all multicast VLANs.

Table 20: Command output

Field

Description

Total 6 entries

Total number of (S, G) entries.

Multicast VLAN 10: Total 3 entries

Total number of (S, G) entries in multicast VLAN 10.

(0.0.0.0, 226.1.1.6)

(S, G) entry, where 0.0.0.0 in the S position means all multicast sources.

Flags

Entry flag.

This field displays one flag or the sum of multiple flags. For example, the value 0x70000020 means that the entry has flags 0x20, 0x10000000, 0x20000000, and 0x40000000.

The following flags are available for an entry:

  • 0x10—The entry is created by the multicast VLAN.

  • 0x20—The entry is created by the sub-VLAN of the multicast VLAN.

  • 0x40—The entry is to be deleted.

  • 0x10000000—This value represents one of the following situations:

    • The entry is newly created.

    • The device receives an IGMP query that matches the (S, G) entry but does not receive any matching IGMPv1 reports within an IGMP general query interval.

  • 0x20000000—The device does not receive IGMPv2 or IGMPv3 reports that match the (S, G) entry within an IGMP general query interval.

  • 0x40000000—The device does not receive IGMPv3 IS_EX (NULL) reports that match the (S, G) entry within an IGMP general query interval.

Sub-VLANs (1 in total)

Sub-VLAN list of the multicast VLAN, and the total number of the sub-VLANs.
