ubr npe-g2 vs 7200 npe-g2

are these actually different boards? the ubr version shows lower
throughput (1.3mpps) vs the 7200 (2mpps). but they seem similar
otherwise: same cpu, ports, etc.

i'm looking around the used market and the ubr versions seem more
available and cheaper, but i am looking for one to go into a 7206vxr.

any wisdom from the crowd?

Joe,

Cisco "UBR" routers are used as cable CMTS devices...

i understand the difference between the ubr and the regular 7200 series.
i'm wondering about just the npe-g2 card. is there any difference between
the npe version for ubr and the version for 7200? is it just a part
number difference? or is there a physical difference of some sort?

I've used a npe-g2 card in a ubr before, but haven't tried the other way
around.

Re: ubr npe-g2 vs 7200 npe-g2 [In reply to]

I think this will answer your question:

For NPE-G2:

"The Cisco 7200 VXR routers and Cisco uBR7200 series routers use different models of the NPE-G1 and the NPE-G2 processors. For the Cisco 7200 VXR routers, order the NPE-G1 or NPE-G1= product. For the Cisco uBR7200 series routers, order the UBR7200-NPE-G1, UBR7200-NPE-G1=, UBR7200-NPE-G2, or UBR7200-NPE-G2= product."

The NPE-G1 cards have a more detailed explanation:

"The Cisco 7200 VXR routers and Cisco uBR7200 series routers use different models of the NPE-G1 processor. For the Cisco 7200 VXR routers , order the NPE-G1 or NPE-G1= product. For the Cisco uBR7200 series router, order the UBR7200-NPE-G1 or UBR7200-NPE-G1= product. The two models of NPE-G1 have different labels and use different boot helper images, and they cannot be interchanged between the Cisco 7200 VXR routers and Cisco uBR7200 series routers."

thanks. i had hunted around but couldn't come up with anything that
clear. i still wouldn't be surprised if you could replace the boot image
and be ok, but for now i'll take cisco at their word.

Re: ubr npe-g2 vs 7200 npe-g2 [In reply to]

Possibly. Are there differences in the I/O ports on the UBR-NPE-G2 and the "non-UBR" NPE-G2? I really haven't had any experience with the UBR models of routers.

I'm not sure if I find "have different labels" a compelling reason for
not being interchangeable (or having different PPS specs).

Boot helper is one of the most misunderstood parts of the 7200 series
anyway... (*and* it can be changed).

They can be changed from/to uBR to "normal" router, by changing the
boot loader. It is sometimes problematic, as the existing bootloader
may hang/crash during bootup, but the ROMMON tftp should work without
problem.

I'd say that the quoted difference in performance is simply from the
fact, that the IOS for NPEs was standarized first, and tested on
first, "light" IOS releases. As the code grow and was backloaded with
uBR features, the real performance was retested and now the quoted
numbers are lower, and more realistic as to current (to publishing
of the docs) performance envelope. But as always, YMMV.

Re: ubr npe-g2 vs 7200 npe-g2 [In reply to]

Again this is only concerning the NPE-G1 according to them..
(I can only go by what Cisco is saying, since I don't know myself)

"The Cisco 7200 VXR routers and Cisco uBR7200 series routers use different models of the NPE-G1 processor"

According to them....

1. The Processors are different.
2. They have different labels (duh).
3. They use different boot helper images (maybe because of the different processor?).

I wish I had a spare to test it out with. If anyone has both, it would be interesting to see the differences.
