[nsp] NPE-G1

[Warren Kumari]

Hi,

I think you may be speaking about the NPE-G100, not the NPE-G1. The 
7304 takes the NPE-G100 and the 7206 takes the NPE-G1 (with has the I/O 
controller built in!).  I have had some very bad experiences with the 
7304, mainly in lab tests (with the box under high load applying or 
removing an ACL would have no effect), but also some crashes in 
production.


I have replaced a bunch of 7500s (RSP4, VIP2-50s) with 7206-NPE-G1s and 
have been very happy. The 7500s were doing MLPPP with 8 E1s (full of 
64byte packets (VoIP)) in a bundle and having severe CPU issues (80-90% 
on the VIP). We replaced them with 7206 and turned on cRTP as well and 
the CPU sits at around 30-40% (we later removed the MLPPP (yay!) and 
saw no real CPU difference). Unfortunately, the CPU goes through the 
roof if you turn on QoS so all this is going to be ripped out and 
replaced soon.

I also replaced a 7500 with an RSP8 with a NPE-G1 and it is working 
great. We are using all 3 of the gig interfaces (2 interfaces have 
around 130Mbps and one is almost idle) and  3 DS3s (and 3 full tables) 
and the CPU sits at around 10-15%. So far it has been really stable and 
has worked really well.

Warren.

Never criticize a man till you've walked a mile in his shoes.  Then if 
he didn't like what you've said, he's a mile away and barefoot.
