19.6.2.2.1 ip igmp access-group
Command: ip igmp access-group {<
acl_num | acl_name
>}
no ip igmp access-group
Function:
Sets the filter criteria for IGMP group on the interface; the “
no ip igmp access-group
”
command cancels the filter criteria.
Parameters:
{<
acl_num | acl_name
>}
is the sequence number of name of the access list, where the
range of
acl_num
is 1 to 99.
Default:
No filter criteria is set by default
Command mode:
Interface Mode
Usage Guide:
This command can be issued to filter the groups on the interface to allow or deny the
participant of some groups.
Example:
Specify interface vlan1 to permit 224.1.1.1 and deny 224.1.1.2.
Switch (Config)#access-list 1 permit 224.1.1.1 0.0.0.0
Switch (Config)#access-list 1 deny 224.1.1.2 0.0.0.0
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp access-group 1
19.6.2.2.2 ip igmp join-group
Command: ip igmp join-group <
A.B.C.D
>
no ip igmp join-group <
A.B.C.D
>
Function:
Joins the interface to an IGMP group; the “
no ip igmp join-group
” command cancels
the join.
Parameters:
<A.B.C.D>
are the IP addresses for multicast groups.
Default:
not joined to groups.
Command mode:
Interface Mode
Usage Guide:
When a switch is used as a host, this command is used to any the host to a group.
Suppose the local interface is to be added to group 224.1.1.1, then the switch will
send a IGMP member report containing group 224.1.1.1 on receiving IGMP group
query from the other switches. Note the difference between this command and the
“
ip igmp static-group
” command.
Example:
Specifying interface vlan1 to join group 224.1.1.1.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp join-group 224.1.1.1
