[f-nsp] exceed configured CAM size, larger partition size required

[Darren O'Connor]

Most interfaces have a single IP, some have 2. No more than that

Check if you have a lot of IP addresses configured on interfaces.  The rACL has to be applied for each inbound IP address the router could be listening on.  The limited CAM size for rACLs can have an impact if there are a lot of IPs and the ACL is long.

Last weekend we added new receive ACLs to our XMRs. All our XMRs (4, 8, and 16) have identical TCAM profiles set up.

I had applied the new receive ACL to 4 XMR4s with no problems. When applying it to an XMR16 in-band I lost connection to the box. Going through OOB I removed and re-added the ACL. I was shown this error:

Odd, as mentioned all my cam-partitions are identical across all boxes. After this happened I did not try and add it to any other box as it was too disruptive.

Any ideas why I would get this? Currently on 5.4d and was upgrading to 5.4e on the night.


Thanks
