SMLT

Split Multi-Link Trunking:

• Avaya
• Multiple links treated as a single link and load balance traffic
  
• Each packet uses hashed algorithm involving source and destination MAC info
• Switches involved become aggregation switches and appear as one logical switch
• If both ends are split in with 2 other devices, and no intermediate "mesh" connections, this is known as a "SMLT square"
• If one end is split, this is known as a "SMLT Triangle"
• SMLT Triangles do not need end devices to support SMLT
• Heavily utilizes IST configuration
• SLMT ID's are given to each SMLT device from end station
• A single unit's ARP requests are given trough IST with its own connection information, this is not the case if redundant connections are present
• Failure of one component results in half a second convergence time
• When using SMLT it is not necessary to enable STP due to no logical bridging loops with IST
• STP should be disabled on all SMLT ports
