config igmp_snooping querier
• By default, the robustness variable is set to 2. You might want to increase this
value if you expect a subnet to be lossy.
last_member_query_interval  The maximum amount of time between group-
specific query messages, including those sent in response to leave-group
messages. You might lower this interval to reduce the amount of time it takes a
router to detect the loss of the last member of a group.
state  If the state is enable, it allows the switch to be selected as a IGMP
Querier (sends IGMP query packets). It the state is disabled, then the switch can
not play the role as a querier. Note that if the Layer 3 router connected to the
switch provide only the IGMP proxy function but not provide the multicast routing
function, then this state must be configured as disabled. Otherwise, if the Layer 3
router is not selected as the querier, it will not send the IGMP query packet.
Since it will not also send the multicast-routing protocol packet, the port will be
timed out as a router port.
Restrictions Only Administrator-level users can issue this command.
Example usage:
To configure IGMP snooping querier:
DES-3028P:4# config igmp
_
snooping querier vlan default query
_
interval
125 state enable
Command: config igmp
_
snooping querier vlan default query
_
interval 125
state enable
Success.
DES-3028P:4#
config router_ports
Purpose Used to configure ports as router ports.
Syntax
config router_ports <vlan_name 32> [add | delete] <portlist>
Description This command allows users to designate a range of ports as being
connected to multicast-enabled routers. This will ensure that all
packets with such a router as its destination will reach the multicast-
enabled router  regardless of protocol, etc.
Parameters
<vlan_name 32>  The name of the VLAN on which the router port
resides.
<portlist>  Specifies a port or range of ports that will be configured
as router ports.
Restrictions Only Administrator-level users can issue this command.
Example usage:
To set up static router ports:
DES-3028P:4#config router_ports default add 1-10
Command: config router_ports default add 1-10
Success.
