config router_ports_forbidden
Purpose
Used to configure ports as forbidden router ports.
Syntax
config router_ports_forbidden [<vlan_name 32> | vlanid <vidlist>] [add
| delete] <portlist>
Description
This command is used to allow designation of a range of ports as
being not connected to multicast-enabled routers. This ensures that
the forbidden router port will not propagate routing packets out.
Parameters
<vlan_name 32>
−
The name of the VLAN on which the router port
resides.
<vidlist>
−
The VID range of the ports to be configured as forbidden
ports.
[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.
Restrictions
Only Administrator level, Operator level or Power User level users can
issue this command.
Example usage:
To set up forbidden router ports:
DES-1228/ME:5#config router_ports_forbidden default add 2-10
Command: config router_ports_forbidden default add 2-10
Success.

enable igmp_snooping
Purpose
Used to enable IGMP snooping on the Switch.
Syntax
enable igmp_snooping {forward_mcrouter_only}
Description
This command is used to enable IGMP snooping on the Switch. If
forward_mcrouter_only is specified, the Switch will learn the router
port based on identification of the multicast routing protocol packet
and the IGMP control packet.
Parameters
forward_mcrouter_only
−
Adding this parameter to the command, the
Switch will learn the router port based on identification of the multicast
routing protocol packet and the IGMP control packet.
Restrictions
Only Administrator level, Operator level or Power User level users
can issue this command.
Example usage:
To enable IGMP snooping on the Switch:
DES-1228/ME:5#enable igmp_snooping
Command: enable igmp_snooping
