38.9.13 ip igmp static-group
Command: ip igmp static-group <A.B.C.D > [source <A.B.C.D >]
no ip igmp static -group <A.B.C.D > [source <A.B.C.D >]
Function: Configure interface to join some IGMP static group; the “no ip igmp static-group” command
cancels this join.
Parameter: <A.B.C.D> is group address;
Source <A.B.C.D> expresses SSM source address of configuration.
Default: Do not join static group
Command Mode: Interface Configuration Mode
Usage Guide: When configuring some interface to join some static group, it will receives about the
multicast packet of the static group whether the interface has a real receiver or not; that is, if configuring
the interface to join static group 224.1.1.1, the interface always receives about multicast packet about
group 224.1.1.1 whether the interface has a receiver or not. Carefully, it is the difference between the
command and ip igmp join-group command.
Example: Configure static-group 224.1.1.1 on interface vlan1.
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ip igmp static-group 224.1.1.1
38.9.14 ip igmp version
Command: ip igmp version <version>
no ip igmp version
Function: Configure IGMP version on interface; the “no ip igmp version” command restores default
value.
Parameter: <version> is IGMP version of configuration, currently supporting version 1, 2 and 3.
Default: version 2.
Command Mode: Interface Configuration Mode
Usage Guide: The command mainly applies to supply upward compatibility of the different version; it is
not communicated between version 1 and version 2, therefore it must configure to the same version
IGMP in the same network. When other routers which are not upgraded to IGMPv3 on
interface-connected subnet need to join member identity collection of subnet IGMP together, the
interface is configured to corresponding version.
Example: Configure IGMP on interface to version 3.
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ip igmp version 3
38.9.15 show ip igmp groups
Command: show ip igmp groups [<A.B.C.D>] [detail]
Function: Display IGMP group information
Parameter: <group_addr> is group address, namely querying specified group information; Detail
expresses group information in detail
