Quicktip: Increasing port-profile max-ports on Nexus 1000v

A common limitation I see customers regularly hitting on the 1000v is the default “max-ports” value of 32 on a port-profile. Once a 33rd virtual machine is assigned a certain port-profile it gives an error and doesn’t allow it.

Fortunately the fix is easy. Just up the value within the port profile:

port-profile MY-PROFILE
    vmware max-ports 64

Note: The range can go as high as 1024. Max-ports configuration only applies to non-uplink ports.
