Cisco Nexus C93240YC-FX2 VPC Suspended with Citrix Netscaler

[emnyman1027]

We have two Cisco Nexus C93240YC-FX2 that we are connecting a Citrix Netscaler SDX to. We are setup with a portchannel on the Netscaler with a link going to Switch A and a link to Switch B. On the switch side, we are setup with a single link portchannel with VPC.

The issue we are seeing is that the port channel goes into suspended state when both links are connected. If we remove one of the two links, the port channel works fine.

Anyone successfully have a netscaler connected to a pair of Nexus switches using VPC?

Thanks!

Are the 2 Nexus switches VPCed together? If yes, make sure all vlans are configured on the vPC peer-link.

If PO to Netscaler does not work, you may want to simply use 2 links configured as trunk or access ports.

Several other VPCs configured on the same switches. Problem is isolated to only the vpc that the netscaler is connected to.

 - Check the logs on both the nexus and the netscaler when this happens, you may find additional info's

Hello,

I could be totally off, but I think you need Cisco RISE for this topology to work:
