Compatibility
Compatibility is maintained by hosts and routers taking appropriate actions depending on the
versions of MLD operating on hosts and routers within a network.
The allowed selection is
MLD-Auto
,
Forced MLDv1
,
Forced MLDv2
, default compatibility
value is MLD-Auto.
MLD-Auto
PRI
Priority of Interface.
It indicates the MLD control frame priority level generated by the system. These values can be
used to prioritize different classes of traffic.
The allowed range is
0
(best effort) to
7
(highest), default interface priority value is 0.
0
RV
Robustness Variable.
The Robustness Variable allows tuning for the expected packet loss on a link.
The allowed range is
1
to
255
, default robustness variable value is 2.
2
QI (sec)
Query Interval.
The Query Interval is the interval between General Queries sent by the Querier.
The allowed range is
1
to
31744
seconds. Default query interval is 125 seconds.
125
QRI (0.1 sec)
Query Response Interval.
The Maximum Response Delay used to calculate the Maximum Response Code inserted into the
periodic General Queries.
The allowed range is
0
to
31744
in tenths of seconds. Default query response interval is 100 in
tenths of seconds (10 seconds).
100
LLQI (0.1 sec)
Last Listener Query Interval.
The Last Listener Query Interval is the Maximum Response Delay used to calculate the
Maximum Response Code inserted into Multicast Address Specific Queries sent in response to
Version 1 Multicast Listener Done messages. It is also the Maximum Response Delay used to
calculate the Maximum Response Code inserted into Multicast Address and Source Specific
Query messages.
The allowed range is
0
to
31744
in tenths of seconds. Default last listener query interval is 10 in
tenths of seconds (1 second).
10
URI (sec)

LLDP
Link Layer Discovery Protocol
(
LLDP
) is an IEEE802.1ab standard OSI layer-2 protocol. LLDP allows Ethernet network
devices to advertise details about themselves, such as device configuration, capabilities and identification. The advertise
packets are periodically sent to directly connected devices on the network that are also using LLDP or so called its neighbours.
LLDP is a “one hop” unidirectional protocol in an advertising mode.
LLDP
information can only be sent to and received by devices, no solicit information or state changes between nodes. The
device has a choice to turn on and off sending and receiving function independently. Advertised information is not forward on
to other devices on the network. LLDP is designed to be managed with SNMP. Applications that use this protocol include
topology discovery, inventory management, emergency services, VLAN assignment, and inline power supply.
