Hi @Kirk J ,
Thank for you reply,
I found the KB on Dell Website, it seems that only some models are supported:
Fabric OS 9.1.0 introduces the Fibre Channel Link Aggregation (FC-LAG) feature to provide FC-LAG capability between Brocade switches and Cisco UCS FIs that are configured in end-host mode. This enhancement on Brocade switches supports three different connectivity options for UCS-FIs.
It provides the advantage of automatic load distribution based on the SID, DID, and OXID across all physical links in the FC-LAG, and it allows it to add and remove physical links to the FC-LAG without application disruption.
When an FOS switch port is configured to be a member of an FC-LAG, the link aggregation protocol is used to communicate with its peer to establish and manage the FC-LAG.
FC-LAG is supported on the following platforms:
- X7-8 Director
- X7-4 Director
- G730 Switch
- G720 Switch
- X6-8 Director
- X6-4 Director
- G630 Switch
When it is enabled, a link aggregation protocol runs between the remote FI and the Brocade switch, and configures all the underlying physical links into a single aggregated links. The bandwidth is adjusted based on the available physical links, which improves load balancing and reduces congestion events.
