7. In the Router Ports Configuration area, choose the methods to use for
detecting when a multicast router is connected to a switch port.
When a multicast router, including IGMP querier, is connected to a switch
port, all multicast packets and IGMP reports are forwarded on that port.
This behavior is important for the proper functioning of IGMP snooping.
You can enable one or both of the following options:
• Autodetect—Accept the default setting of Enabled if you want the
switch to automatically determine whether an end station or multicast
router is connected to its ports. To determine which type of device is
connected to a port, the switch uses Cisco Discovery Protocol (CDP)
or Multicast Router Discovery (MRD).
• Manual—Enable this setting if you need to connect a switch from a
different vendor that does not support CDP or MRD protocols. When
you enable the Manual setting, a series of checkboxes appears, so you
can specify which ports will be connected to a router that does
not
support CDP or MRD protocols.
8. From the Multicast Packets Forwarding pull-down menu, choose where to
forward multicast packets.
• To Listeners Only—The switch forwards multicast packets to ports in
the Listening state only.
• To Listeners and Uplink Port—The switch forwards multicast packets
to ports in the Listening state and the uplink port. This is the default
setting.
• To Listeners and All Snooper Ports (Standard)—The switch forwards
multicast packets to ports in the Listening state and to all multicast
routers, or snoopers. Use this setting if you want multicast traffic to be
filtered only on ports where end stations are connected and not
between switches.
9. From the Uplink Port pull-down menu, choose Autodetect (Querier) if
you want the Stratix 6000 switch to automatically determine the uplink
port. Otherwise, set the uplink port manually by choosing a specific port.
10. Click Apply Changes.
The changes will take effect immediately without requiring you to cycle
power to the switch.
TIP This setting is useful if you need to route multicast packets between
two networks.
