config igmp_snooping querier
value of the robustness variable.
• 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 an 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.
version – Specifies the version of IGMP packet that will be sent by this VLAN.
Only Administrator-level users
can issue this command.
Restrictions
Example usage:
To configure IGMP snooping querier:
DES-3200-28:4#config igmp
interval 125
state enable
Success.
DES-3200-28:4#
config router_ports
Used to co
nfigure ports as router ports.
Purpose
config route
r_ports [<vlan_name 32> | vlanid <vidlist>] [add | delete]
<portlist>
Syntax
This
command is used 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.
Description
Parameters
<vlan_name 32> The name of the VLAN on which the router port
resides.
<vidlist> The VID range of the router ports to be configured.
[add|delete] Specifies whether to add or delete router ports to be
configured.
<portlist> Specifies a range of ports to be configured.
Only Administrator-level users
can issue this command.
