Mlt-Based Smlt With Single Port Smlt - Avaya 8600 Configuration Manual

• You cannot configure a port as an MLT-based Split MultiLink trunk and as a single port
SMLT at the same time.
• Two or more aggregation switches can have single port Split MultiLink trunk with the same
IDs. You can have as many single port Split MultiLink trunk as there are available ports
on the switch.
• LACP is supported on single port SMLT.

MLT-based SMLT with Single Port SMLT

You can configure an split MultiLink trunk with a single port split MultiLink trunk on one side
and an MLT-based split MultiLink trunk on the other. Both must have the same SMLT ID.
Note:
You can configure Link Aggregation/MLT group IDs from 1 through 256. The switch supports
a total of 128 MLT groups. Avaya suggest that users start numbering S-SMLT or SLT IDs to
avoid overlapping MLT IDs in the 1 through 128 range. SLT IDs range from 1 through 512.
If you start at 129, a switch can support the full capacity of 383 SLT ports or IDs.

ID is 10, the steps are:
1. Configure switch A and B with MTL-based SMLT.
2. Disable all ports and then delete MLT-based SMLT 10 on switch B. All traffic
3. Configure single port SMLT ID 10 on switch B and then enable the port. Traffic

5. Configure single port SMLT 10 on switch A and then enable the port. Traffic switched
