Split Multi-Link Trunking

A split multilink trunk is a multilink trunk with one end split (shared) between two aggregation
switches. Using Single Link Trunking (SLT), you can configure a split multilink trunk using a
single port. This permits the scaling of the number of split multilink trunks on a switch to the
maximum number of available ports.
For configuration procedures for the Avaya Split Multi-Link Trunking feature for the Ethernet
Routing Switch 8800/8600, see Switch Clustering using Split-Multilink Trunking (SMLT)

Tool , NN48500-536.
