Today I was working on a problem with the Nexus 1000v. The switch reached the port count above 8192, and we got the error:
The numPorts value: <xxxx> in spec exceeded maxPorts 8192
The solution was to change the default max numPorts from 8192 to 30000. The 30000 value is also the one mentioned in the Configuration Maxium document: vsp_41_config_max.pdf.
VMware vCenter 4.0 max ports per DVS = 8192
VMware vCenter 4.1 max ports per DVS = 20,000
VMware vCenter 5.0 max ports per DVS = 30,000
Nexus 1000v maximum veth ports = 2048
My question was does changing the max-ports have impact, the answer is: It has no impact.
This is what I did:
