38-92
38.11.10 ip igmp proxy limit
Command: ip igmp proxy limit {group <g_limit> | source <s_limit>}
no ip igmp proxy limit
Function: To configure the maximum number of groups that upstream ports can join, and the maximum
number of sources in a single group.
Parameter: g_limit: <1-500>, the group number limitation.
s_limit: <1-500>, the source number limitation.
Command Mode: Global Mode.
Default: Most 50 groups in default, and most 40 sources in one group.
Usage Guide: If the group number limitation is exceeded, new group membership request will be
rejected. This command is used to prevent malicious group membership requests.
Example:
Switch(config)#ip igmp proxy limit group 30 source 20
38.11.11 ip igmp proxy multicast-source
Command: ip igmp proxy multicast-source
no ip igmp proxy multicast-source
Function: To configure the port as downstream port for the source of multicast datagram; the no from of
this command disables the configuration.
Command Mode: Interface Configuration Mode.
Default: The downstream port is not for the source of multicast datagram.
Usage Guide: When a downstream port is configured as the multicast source port, the switch will be able
to receive multicast data flow from that port, and forward it to the upstream port. To make this command
function, the multicast router which is connected to the upstream port of the switch, should be configured
to view the multicast source from the upstream port is directly connected to the router.
Example: Enable igmp proxy multicast-source in downstream port VLAN1.
Switch (config)#interface vlan 1
Switch (Config-if-Vlan1)#ip igmp proxy multicast-source
38.11.12 ip igmp proxy unsolicited-report interval
Command: ip igmp proxy unsolicited-report interval <value>
no ip igmp proxy unsolicited-report interval
Function: To configure how often the upstream ports send out unsolicited report.
Parameter: The interval is between 1 to 5 seconds for the upstream ports send out unsolicited report.
Command Mode: Global Mode.
Default: The interval is 1 second for the upstream ports send out unsolicited report in default.
Usage Guide: The upstream ports re-transmit the unsolicited reports in order that the router will not miss
the report packet due to link down or packet loss. This command configures the interval for
re-transmition.
