M/T were "enterprise" feature sets, where anything with 'S' meant
Service Provider. For the CPU-driven platforms and 7600 it is still
the case.

It's a router, with switch LCs unless you're equipped with ES/ES+/SIP
linecards. Starting from Sup2T it's router even with traditional LCs,
as VLAN interfaces were coupled with the logical interface ID, and
that effectively provided VLAN independence per-port.
