IGMP cache, but the switch is not a member. Therefore it can support fast switching.
To configure IGMP static Join, use the following command.
Command Mode Description
ip igmp static-group A.B.C.D
vlan VLAN port PORT reporter
A.B.C.D
Configures IGMP static join setting.
A.B.C.D: group address
no ip igmp static-group
[A.B.C.D] [
vlan VLAN]
no ip igmp static-group A.B.C.D
vlan VLAN port PORT reporter
A.B.C.D
Global
Disables the IGMP static join configuration.
9.2.2.2 Maximum Number of Groups
Hosts on a subnet serviced by a particular interface have the access to join certain multi-
cast groups. These multicast groups can be controlled by the ip igmp access-group
command.
To control the multicast groups on an interface, use the following command.
Command Mode Description
ip igmp access-group {<1-99> |
WORD}
Sets an IGMP access group.
1-99: access list number
WORD: IP named standard access list
no ip igmp access-group
Interface
Disables groups on interfaces.
9.2.2.3 IGMP Query Configuration
Multicast routers send host membership query messages (host query messages) to dis-
cover which multicast groups have members on the attached networks of the router.
Hosts respond with IGMP report messages indicating that they wish to receive multicast
packets for specific groups (indicating that the host wants to become a member of the
group). Host query messages are addressed to the all-hosts multicast group, which has
the address 224.0.0.1, and has an IP time-to-live (TTL) value of 1.
The designated router for a LAN is the only router that sends IGMP host query messages.
For IGMP Version 2, the designated querier is the router with the lowest IP address on
the subnet. If the router hears no queries for the timeout period, it becomes the querier.
To configure an IGMP query interval, use the following command.
Command Mode Description
ip igmp query-interval
<1-18000>
Configures the IGMP query interval.
1-18000: frequency at which IGMP host query mes-
sages are sent (unit: second)
no ip igmp query-interval
Interface
Returns to the default value. (125)
Use this command to configure the timeout period before the router takes over as the
