Max port-channel count per Nexus 9300

[from88]

Hello,

As already maybe you guys know Nexus 9300 has port-channel limit which is 256. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/scalability/guide_703I77/b-Cisco-Nexus-9000-Series-NX-OS-Verified-Scalability-Guide-703I77.html

I need to know which port-channels counts into that number ? Do this number says that there could be only any 256 port channels per device. Or it states that there could be only 256 in whole FEX configuration (host interfaces and FEX uplinks are counted in) or that number says there could be only 256 end hosts port-channels configured - so this would not count other port-channels in device like L3 uplinks, Fex interfaces and etc.

P.S Fexes are connected in a straight through mode using VPC technology

Thanks for any input !

Hello!

The value listed in the Nexus 9000 Series NX-OS Verified Scalability Guide includes all port-channels. This includes Layer 2 port-channels, Layer 3 port-channels, vPCs, FEX fabric port-channels connecting to FEX uplinks, and port-channels consisting of FEX host interfaces connecting to downstream hosts.

I hope this helps - thank you!
