LABEL DESCRIPTION
Leave Timeout Enter an IGMP leave timeout value (from 1 to 16,711,450) in seconds. This defines how many
seconds the OLT waits for an IGMP report before removing an IGMP snooping membership
entry when an IGMP leave message is received from a host.
802.1p Priority Select a priority level (0-7) to which the OLT changes the priority in outgoing IGMP control
packets. Otherwise, select No-Change to not replace the priority.
Proxy Select MGMDv3 Mode to enable Multicast Group Membership Discovery version three
(MGMDv3) and have the OLT send IGMPv3 or MLDv2 queries instead of IGMPv2 or MLDv1
queries.
MGMDv2 indicates IGMPv2 in IPv4 networks and MLDv1 in IPv6 networks. MGMDv3 indicates
IGMPv3 in IPv4 networks and MLDv2 in IPv6 networks.
Note: MGMDv3 only applies in IGMP proxy mode.
Unknown Multicast Specify the action to perform when the OLT receives an unknown multicast frame.
Frame
Select Drop to discard the frame(s).
Select Flooding to send the frame(s) to all ports.
Reserved Multicast Multicast addresses (224.0.0.0 to 224.0.0.255) are reserved for the local scope. For examples,
Group 224.0.0.1 is for all hosts in this subnet, 224.0.0.2 is for all multicast routers in this subnet, etc. A
router will not forward a packet with the destination IP address within this range. See the IANA
web site for more information.
Specify the action to perform when the OLT receives a frame with a reserved multicast
address.
Select Drop to discard the frame(s).
Select Flooding to send the frame(s) to all ports.
Port This field displays the port number.
* 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.
Note: Changes in this row are copied to all the ports as soon as you make them.
Immed. Leave Select this option to set the OLT to remove this port from the multicast tree when an IGMP
version 2 leave message is received on this port.
Select this option if there is only one host connected to this port.
IGMP Querier The OLT treats an IGMP query port as being connected to an IGMP multicast router (or server).
Mode The OLT forwards IGMP join or leave packets to an IGMP query port.
Select Auto to have the OLT use the port as an IGMP query port if the port receives IGMP
query packets.
Select Fixed to have the OLT always use the port as an IGMP query port. Select this when you
connect an IGMP multicast server to the port.
Select Edge to stop the OLT from using the port as an IGMP query port. The OLT will not keep
any record of an IGMP router being connected to this port. The OLT does not forward IGMP
join or leave packets to this port.
Apply Click Apply to save your changes to the OLT's run-time memory. The OLT loses these changes
if it is turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
