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) Technical
Configuration Guide, NN48500-518 or Switch Clustering (SMLT/SLT) Configuration Tool ,
NN48500-536.
