System and method for determining the configuration of switches in virtual link trunking environments

摘要

A system and method of determining the configuration of a network switching unit includes receiving a configuration message on a network link. The network switching unit is associated with a first switch ID and belongs to a domain associated with a first domain ID. The system and method further includes identifying a second domain ID and a second switch ID based on at least information associated with the configuration message; determining whether the first domain ID and the second domain ID match; if the first domain ID and the second domain ID match, adding the network link to a first link aggregation group (LAG) associated with the second switch ID and designating the first LAG as part of an intra cluster link (ICL); and if the first domain ID and the second domain ID do not match, adding the network link to a second LAG associated with the second domain ID.

1. A network switching unit comprising:
one or more hardware processors; wherein the one or more hardware processors are configured to execute code to cause the network switching unit to perform operations comprising: receiving a first configuration message on a first network link coupling the network switching unit to another network switching unit; identifying a first domain ID assigned to the another network switching unit based on the first configuration message; determining whether the first domain ID matches a second domain ID assigned to the network switching unit; in response to determining that the first domain ID matches the second domain ID adding the first network link to a first link aggregation group (LAG) associated with the first domain ID and designating the first LAG as part of an intra cluster link (ICL); in response to determining that the first domain ID does not match the second domain ID, adding the first network link to a second LAG associated with the first domain ID; andforwarding network traffic using the first LAG and the second LAG andthe second LAG to improve the forwarding by the network switching unit and redundancy of a network.
