In 6400's there are NSP's (Network Switch Processors) and NRP's (Network Route Processors). There can be redundant NRP's and NSP's. NSPA refers to primary/active NSP and NSPB refers to backup NSP.
thanx don, I am familiar w/ nrp & nsp, however when I heard a colleague refer to an nspa way out of context it seamed he couldn't possibly be referring to a the same device. Apparently I was mistaken.
Thanks again,
