The author's specifications eliminated Cisco's 4900M from the
competition. That not unexpected though since it was a evaluation of
access switches w/ 10G uplinks. The 4900M has 8 on-board 10G interfaces
and expansion modules that can carry 8 more (not oversubscribed) or 16
(oversubscribed). It has has GigE support via TwinGig modules in the
expansion module bays. It also has a 320Gbps backplane and can handle
up to 200k v4 routes. It's an impressive little switch if you need 10G
aggregation. It can't handle a full table of course but it still has a
lot of use. No MPLS options. It's based on the 4500's Sup 6-E.

The base unit starts at $16k.
