[c-nsp] 4500 series overview

[Justin Shore]

Can someone point me to an overview of the 4500s or remind me of some of 
the specifics of the box?  I haven't had to work with them in several 
years and I'm trying to catch up on the latest greatest as well as 
remember the nitty gritty I used to know.

The boxes I'll be working with are a mix of E and non-E series.  Best 
Sup I see in them is a Sup 5 (including in the E chassis').  They're all 
doing routing, IGPs, EGP, and VRF-Lite as well as PoE access ports.  I'm 
trying to recall the linecard and backplane specs.  IIRC the non-E 
chassis and non-E LCs are limited to 6GBps.  That's spread out across 
the ASICs on the LC so a group of 8 ports on a 48-port LC shares 1Gbps 
to the backplane.  I think that's right.  The E-series chassis with the 
Sup 6 supported 24Gbps I believe.  No MPLS support.  The last thing I 
recall is that you had to have a 4507 or better to install dual Sups. 
Am I missing anything important?

It's been a good while since I touched one of these guys.  They were too 
small for use in my SP so I ignored them for the most part.  Now I need 
to get back up to speed.  I'm reading the data sheets now but they 
aren't giving me the finer detailed stuff that I'm sure is out there.

Thanks
  Justin
