Igmp-Snooping Host-Aging-Time - HP A5120 EI Series Command Reference Manual

Default level
2: System level
Parameters
acl-number: Specifies a basic or advanced ACL number, in the range of 2000 to 3999. The source
address or address range specified in the advanced ACL rule matches the multicast source addresses
specified in IGMPv3 reports, rather than the source address in the IP packets. The system assumes that an
IGMPv1 or IGMPv2 report or an IGMPv3 IS_EX and TO_EX report that does not carry a multicast source
address carries a multicast source address of 0.0.0.0.
vlan vlan-list: Specifies one or multiple VLANs. You can provide up to 10 VLAN lists. For each list, you
can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to end-
vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The effective range of a VLAN ID
is 1 to 4094.
Description
Use the igmp-snooping group-policy command to configure a multicast group filter on the current port(s),
namely, to control the multicast groups that the hosts on the port can join.
Use the undo igmp-snooping group-policy command to remove the multicast group filter.
By default, no multicast group filter is configured on an interface. Namely, a host can join any valid
multicast group.
If you do not specify any VLAN when using this command in Layer 2 Ethernet interface view or Layer 2
aggregate interface view, the command takes effect in all VLANs that the interface belongs to. If you
specify a VLAN or multiple VLANs, the command takes effect in the specified VLANs that the interface
belongs to.
If you do not specify any VLAN when using this command in port group view, the command takes effect
on all the ports in this group. If you specify a VLAN or multiple VLANs, the command takes effect only on
those ports in this group that belong to the specified VLANs.
If the specified ACL does not exist or the ACL rule is null, all multicast groups are filtered out.
You can configure different ACL rules for a port in different VLANs. For a given VLAN, a newly
configured ACL rule overrides the existing one.
Related commands: group-policy.

# Apply ACL 2000 as a multicast group filter so that hosts on GigabitEthernet 1/0/1 in VLAN 2 can join
225.1.1.1 only.
