Hi Frdz,

We have nexus 9300 switches, we are getting "sufficient free entries are not available in Tcam bank" error while configuring the ACL.

Pls suggest how to change TCAM allocation for ACL issue.

Appreciate for your response,.

Hello!
One of my teammates recently created a walk-through video on Nexus 9000 TCAM carving. I would encourage you to watch it to see if it helps fill any knowledge gaps regarding TCAM carving. You can find the link here: https://www.youtube.com/watch?v=ISJ4C8ISKCw
