Smlt Topologies; Smlt And Interswitch Trunking - Avaya 8600 Configuration Manual

Link aggregation fundamentals

SMLT topologies

There are three generic topologies in which you can deploy SMLT:
• A triangle topology
• A square topology
• A full-mesh topology (depending on the resiliency and redundancy required)
For information about SMLT topologies and what topologies are supported per product, see
Switch Clustering (SMLT/SLT/RSMLT/MSMLT) Supported Topologies and Interoperability with
ERS 8600 / 5500 / 8300 / 1600, NN48500-555.

SMLT and Interswitch trunking

Figure 5: SMLT aggregation switches and operations
configuration with a pair of Avaya Ethernet Routing Switch 8800/8600 devices (E and F) as
aggregation switches and four separate user access switches (A, B, C, and D).
You must connect SMLT aggregation switches through an interswitch trunk. For example, user
access switches B and C connect to the aggregation switches through MultiLink trunks split
between the two aggregation switches. As shown in
operations
aggregation switches. You must connect these switches through an interswitch trunk.
