| Certification Program Name: | Split Multi-Link Trunking (Nortel) |
| Certification Program ID: | 10617 |
| Certification Program Category: | Switch Interoperability |
| Description: | This certification verifies that the device under test supports the aggregation of multiple ports and failover using Nortel's "SMLT" protocol. |
| Interpretation: | Devices earning this certification have illustrated that they can aggregate links to/from products implementing Nortel's Split Multi-Link Trunking protocol. While non-Nortel devices do not necessarily implement SMLT code, they have been shown to function in conjunction with the Nortel gear.

Nortel Passport 8600 |
| Product Applicability: | This test is a optional test for all vendors switches supporting this function evaluated during Switch Interoperability 2003. This test was not offered in 2004 because Nortel did not participate in the study. |
| Testing Overview: | The Tolly Group will configure two ports on each Nortel Passport 8600 switch for the Inter-switch Trunk between two Nortel Passport 8600 switches and configure other two ports on each Nortel Passport 8600 to provide the "gold standard" termination of the MLT. The DUT will be configured for the general Link Aggregation support and two links from the DUT will cross-connect to the two Nortel Passport 8600 and the same applies to the other DUT. Testers will verify that traffic flows across both ports to//from the DUT. The DUT must illustrate that when the single link between two switches is oversubscribed that additional traffic overflows on to one or more of the aggregated links. |
