Host-Aging-Time (Igmp-Snooping View) - HP 6125XLG Command Reference Manual

Predefined user roles
network-admin
Parameters
acl-number: Specifies an IPv4 basic or advanced ACL by its number, in the range of 2000 to 3999. A
host can join only the multicast groups that match the permit statement in the specified ACL. The source
addresses in the basic ACL rule are the multicast group addresses specified in IGMP reports. The source
and destination addresses in the advanced ACL rule are the multicast source addresses and multicast
group addresses specified in IGMP reports, respectively. The system assumes that 0.0.0.0 is the multicast
source address of an IGMPv1 or IGMPv2 report or an IGMPv3 IS_EX and TO_EX report that does not
carry a multicast source address.
vlan vlan-list: Specifies a space-separated list of up to ten VLAN items. Each item specifies a VLAN by
its ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094. If this option is not specified, this command takes effect for all VLANs.
Usage guidelines
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 on a port in different VLANs. However, for a given VLAN, a newly
configured ACL rule overrides the existing one.
This command is effective for the multicast groups that a port joins dynamically. If you configure the port
as a static member port for a multicast group, this command is not effective for the multicast group.
The global configuration is effective on all ports, but has a lower priority than the configuration made on
a specific port.
Examples
# Apply ACL 2000 as a multicast group filter for VLAN 2 so that the hosts in this VLAN can join only the
multicast group 225.1.1.1.
