H3C S7500E Series Ethernet Switches Chapter 1 IGMP Snooping Configuration Commands
1-14
By default, the aging time of group member ports is 260 seconds.
This command takes effect only if IGMP Snooping is enabled in the VLAN.
Related commands: host-aging-time.
Examples
# Set the aging time of group member ports to 300 seconds in VLAN 2.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-vlan2] igmp-snooping host-aging-time 300
1.1.15 igmp-snooping host-join
Syntax
igmp-snooping host-join group-address [ source-ip source-address ] vlan vlan-id
undo igmp-snooping host-join group-address [ source-ip source-address ] vlan
vlan-id
View
Ethernet interface view, port group view
Parameters
group-address: Address of the multicast group that the simulated host is to join, in the
range of 224.0.1.0 to 239.255.255.255.
source-address: Address of the multicast source that the simulated host is to join. The
value of this argument should be a valid unicast address or 0.0.0.0. If the value is
0.0.0.0, this means that no multicast source is specified.
vlan vlan-id: Specifies the VLAN that comprises the Ethernet port(s), where vlan-id is in
the range of 1 to 4094.
Description
Use the igmp-snooping host-join command to configure the current port(s) as
simulated multicast group member host(s).
Use the undo igmp-snooping host-join command to remove the current port(s) as
simulated multicast group member host(s).
By default, this function is disabled.
Note that:
z This command works on IGMP Snooping–enabled VLANs and VLANs with IGMP
enabled on the corresponding VLAN interfaces. The version of IGMP on the
simulated host depends on the version of IGMP Snooping running in the VLAN or
the version of IGMP running on the VLAN interface.
