As a minimum you need a Supervisor III with a NFFC. The NFFC is a WS-F5521 as
opposed to the more expensive NFFC2 WS-F5531/5531A daughtercard.
You can use an external router to do the job that the RSM does .... different
environments but you can learn enough to pass using a 2620 as the external RP.
There are some differences with ethernet cards as well - WS-X5224 24 port 10/100
blade does not do inline rewrite, WS-X5225 does ... inline rewrite basically transfers
the packet rewrite functions of the NFFC/NFFC2 to the level of ASICs in the card. Its
not on the test but its a big issue if you're trying to use a 55xx box with its limited
backplane. All the 65xx linecards support inline rewrite.
I used to work for a reseller that is very active in the education market ... here is
some design/pricing wisdom for you.
As a base I'd buy a WS-C5505 chassis, a WS-X5530-E2 supervisor, and a WS-X5213A
blade. Don't buy a WS-X5213 - won't work in a 55xx chassis even though they physically
fit. The chasis is $1950 new in distribution, the 5213A is not more than $1k, and the
engine should be not more than $5k. It costs $2100 to upgrade a WS-X5530-E1 to the
latest/greatest and those cards can be had for $1500 if you dig ... but keep in mind I
am digging, too, and I don't have an approval process to go through when I buy :-)
For the RP I'd go with a 2620 if you want something you can put a voice card into
later or if you've got an NP-1FE in one of those 4500s you're already set.
