config igmp_snooping querier
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-1228/ME: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-1228/ME: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-1228/ME:4#config router_ports default add 1-10
Command: config router_ports default add 1-10
Success.
DES-1228/ME:4#
config router_ports_forbidden
Purpose
Used to configure ports as forbidden multicast router ports.
Syntax
config router_ports_forbidden <vlan_name 32> [add | delete] <portlist>
Description
This command allows designation of a port or range of ports as being forbidden to
multicast-enabled routers. This will ensure that multicast packets will not be forwarded to
this port
−
regardless of protocol, etc.
Parameters
<vlan_name 32>
−
The name of the VLAN on which the router port resides.
[add | delete]
−
Specifies whether to add or delete forbidden ports of the specified VLAN.
<portlist>
−
Specifies a range of ports that will be configured as forbidden router ports.
