Our current environment has two PA-850s connecting to two Cisco Nexus switches. Each PA-850 has a fiber connection to each Nexus. The Nexus has a configuration of a single port-channel covering all four fiber links. Is this how it should be done, or should I have a port-channel for PA-3220 (1) and another port-channel for PA-3220 (2)?
PA (1) Eth1/9 --> Nexus (1) Eth1/9
PA (1) Eth1/10 --> Nexus (2) Eth1/10
PA (2) Eth1/9 --> Nexus (2) Eth1/9
PA (2) Eth1/10 --> Nexus (1) Eth1/10
Thank you for the post @jjohnsona
Based on what you have described, I would avoid having a single port channel with 4 links. You should create 2 port channels instead. Since you have 2 fiber cables from each PA to each Nexus, you can create 2x vPC on Nexus side (one port-channel for each PA) or re-cable the connection and have 2 fiber cables from PA1 to Nexus 1 (port channel 1) and 2 fiber cables from PA2 to Nexus 2 (port channel 2).
