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 method comprising:
receiving a first configuration message on a first network link of a network switching unit, the network switching unit being assigned a first switch ID and belonging to a domain being assigned a first domain ID; identifying a second domain ID and a second switch ID based on at least information contained in the first configuration message; determining whether the first domain ID and the second domain ID match; in response to determining that the first domain ID and the second domain ID match:
adding the first network link to a first link aggregation group (LAG) associated with the second domain ID; anddesignating the first LAG as part of an intra cluster link (ICL); in response to determining that the first domain ID and the second domain ID do not match, adding the first network link to a second LAG associated with the second domain ID; and forwarding, by the network switching unit, network traffic using the first LAG and the second LAG to improve the forwarding by the network switching unit and redundancy of a network.
