Nexus 1000v Uplink port Blocked by admin

Hello,

I recently install and configure a Nexus 1000v!

I migrate a server on a vlan dedicated with an adapted port-profile (access vlan).

I can ping this server but someting trouble me : when I go to the configuration tab of my switch I can see that my server's port is green (up and not blocked) and showing the right vlan ID but the uplink port is grey and blocked by admin.

I think ping works because it uses the system VLAN but other flow will not pass.

Can someone explain me why the port is in grey and how could I unblock this port.


Thanks a lot for your help ans sorry for mistakes, I'm a french student.

Benoit

Hi Ben,

i suppose you are hitting Cisco Bug-ID CSCub11514.

https://tools.cisco.com/bugsearch/bug/CSCub11514

"Uplinks with additional features sometimes show as blocked in vCenter"

Workaround:

To clear this issue go to Networking -> N1k DVS -> Ports -> Start Monitoring Port State (upper right corner)

At least, this workaround has solved the issue in my N1Kv installation. :slightly_smiling_face:

I've tested your workaround and work fine the status has changed into active.

My problem now is on the VM, it loses the gateway address; any help?

Thanks
