config router_ports_forbidden
Syntax
config router_ports_forbidden <vlan_name 32> [add | delete]
<portlist>
Description This command allows you to designate 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. The port list is specified by listing the lowest
switch number and the beginning port number on that switch,
separated by a colon. Then the highest switch number, and the
highest port number of the range (also separated by a colon) are
specified. The beginning and end of the port list range are separated
by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4
specifies switch number 2, port 4. 1:3-2:4 specifies all of the ports
between switch 1, port 3 and switch 2, port 4 − in numerical order.
Restrictions Only administrator-level users can issue this command.

To set up forbidden router ports:
DXS-3326GSR:4#config router_ports_forbidden default add 2:1-2:10
Command: config router_ports_forbidden default add 2:1-2:10
