Sample Multi-hop FSB configuration
The following is a sample multi-hop FSB topology.
In this topology:
● FSB1 and FSB2—access FSBs.
● FSB3 and FSB4—core FSBs.
● VLT is configured between FSB1 and FSB2, and requires port-pinning for VLT port channels configured between access
FSBs and core FSBs. The port modes are:
○ Directly-connected CNA ports—ENode
○ Ports connected to FSB3 and FSB4—FCF
● VLT is configured between FSB3 and FSB4, and requires port-pinning for VLT port channels configured between access and
core FSBs. The port modes are:
○ Ports connected to FSB1 and FSB2—ENode-transit
○ Ports connected to FCFs, for pinning to work at ENode port—FCF
The following table lists the high-level configurations on FSB1, FSB3, and FCF1. These configurations apply to FSB2, FSB4, and
FCF2, respectively.
