Notes on Circuit Ports and Circuit GigaStream in Fabric Maps

As mentioned in the pre-requisites section, Circuit ports and Circuit GigaStreams are required for creating Fabric Maps. Refer to the following notes:

■

You cannot specify the Circuit Ports and Circuit GigaStreams that are to be used in a fabric map. You can only define the Circuit Ports and Circuit GigaStreams.

■

Circuit Ports and the Circuit GigaStream for the fabric path are selected as follows:

o

Circuit GigaStreams at the first clusters are selected randomly for efficient load balancing.

o

For hop beyond second hops, previously used circuit Gigastreams may be selected if ‘Resource Sharing’ is set to enabled mode. This allows to reuse the circuit tunnels previously created. Refer to Share Circuit ID Resource.

■

For circuit GigaStreams on the circuit links that connect two clusters, it is recommended to not have more than one ingress GigaStream in any of the devices of the cluster.

Consider the following leaf-spine topology. Fabric map is created between the two leaf nodes and the spine node. The second circuit GigaStream in the leaf node may be used when the circuit ports are of different speeds.
