[c-nsp] Service Policy per-class bandwidth graphing -- any tools available?

[Eric Cables]

Dean,

Thanks for the reply, very helpful info.  The platform is a 7200VXR
NPE-G2.  The policy isn't exactly static, changing versions as new
classes are defined (QOS_POLICY_V1 -> QOS_POLICY_V2, for example).

I think it may be difficult with the dynamic nature to define any
static OIDs to graph, unless the persistence you mentioned has been
implemented.  I'll do some additional research to see what options are
available.

Thanks again..
