Table 144 SWITCHING > Multicast > IPv6 Multicast > Port Role Setting
LABEL DESCRIPTION
MLD Snooping-proxy Port Role Setting
MLD Snooping-proxy
VLAN ID Select the VLAN ID for which you want to configure a port’s MLD snooping-proxy settings.
SLOT This field appears only in Stacking mode. Click the drop-down list to choose the slot
number of the Switch in a stack.
Port This field displays the port number. In Stacking mode, the first number represents the slot
ID and the second is the port number. Please note that the default stacking ports (the
last four ports of your Switch) cannot be configured. They are reserved for stacking only.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first
to set the common settings and then make adjustments on a port-by-port basis.
Changes in this row are copied to all the ports as soon as you make them.
Port Role A port on the Switch can be either a Downstream port or Upstream port in MLD. A
downstream port connects to MLD hosts and acts as a multicast router to send MLD
queries and listen to the MLD host’s Report and Done messages. An upstream port
connects to a multicast router and works as a host to send Report or Done messages
when receiving queries from a multicast router.
Otherwise, select None if the port is not joining a multicast group or does not belong to
this VLAN.
