About single port SMLT
Single port SMLT lets you configure a split multilink trunk using a single port. The single port SMLT behaves just like an MLT-based SMLT and can coexist with SMLTs in the same system. Single port SMLT lets you scale the number of split multilink trunks on a switch to a maximum number of available ports.
Split MLT links may exist in the following combinations on the SMLT aggregation switch pair:
- MLT-based SMLT + MLT-based SMLT
- MLT-based SMLT + single link SMLT
- single link SMLT + single link SMLT
Rules for configuring single port SMLT:
- The dual-homed device connecting to the aggregation switches must be capable of supporting MLT.
- Single port SMLT is supported on Ethernet, POS, and ATM ports.

Note:
Single port SMLT is not supported on 10 Gig Ethernet ports with release 3.5.
|
- Each single port SMLT is assigned an SMLT ID from 1 to 512.
- Single port SMLT ports can be designated as Access or Trunk (that is, IEEE 802.1Q tagged or not), and changing the type does not affect their behavior.
- You cannot change a single port SMLT into an MLT-based SMLT by adding more ports. You must delete the single port SMLT, and then reconfigure the port as SMLT/MLT.
- You cannot change an MLT-based SMLT into a single port SMLT by deleting all ports but one. You must first remove the SMLT/MLT and then reconfigure the port as single port SMLT.
- A port cannot be configured as MLT-based SMLT and as single port SMLT at the same time.
