[nsp] Tcam capacity on 7603/Sup2/Msfc2

[Tim Stevenson]

ODM will probably not help, it looks like you are running out of ACL labels, which most likely means you have too many ACLs configured.

How many unique ACLs are configured? Also, how many PBR and QoS enabled interfaces?

Each L3 interface with a *unique* combination of ACLs, PBR, & QoS will consume one of the 512 available labels.
