configuration.

MultiLink Trunking

MultiLink Trunking (MLT) is a point-to-point connection that aggregates multiple ports to
logically act like a single port, with the aggregated bandwidth. Grouping multiple ports into a
logical link provides a higher aggregate on a switch-to-switch or switch-to-server application.
MLT provides module redundancy via Distributed MultiLink Trunking (DMLT). DMLT allows you
to aggregate similar ports from different modules. Avaya recommends always using DMLT
when possible.
To include ports as trunk group members of an MLT, you must statically configure the ports.

MLT traffic distribution algorithm
You can use a MultiLink trunk to aggregate bandwidth between two switches. The Ethernet
Routing Switch 8800/8600 uses one of two algorithms to determine which active port in the
MultiLink trunk to use for each packet. The MLT algorithms provide load sharing, not load
balancing. The MLT algorithms ensure that each packet in a flow does not arrive out of
sequence, and that any one flow always traverses the same link path.
The algorithms are the same traffic distribution algorithms used for the IEEE 802.3ad-based
link aggregation. Note that the distribution is determined by the ingress port.

calculated by the MLT hash algorithm
You can use the ping snoop command as a tool to determine which link in an MLT a flow is
traversing on.
