Does Nexus 5500/7000 has limitations on number of trunk ports we could use?

[j.boutin]

Hi guys,

I am wondering if the nexus platform either 5000/5500 series or 7000 series have some limitations on the number of active trunk ports we could configure as well as passing traffic on them. I haven't find such references in the documentation but I wouldn't be surprised that such limitation exist on one of those platform.

Thank you for your help!

There is a limit to the number of port channels that you can create

Is there a link where I could find those limitations?

Hi

N7k supports 256 vpc port-chanels 16 ports each (8 active, 8 standby)

I think this link will be helpful:

For trunk limitation - here is a gude about supported logical ports which are counted using following formula: (trunk ports) * (vlans configured on them)
