[c-nsp] 6500 sup32 v sup720

[Alex Foster]

Many thanks for your comments Asbjorn....I think I know where Im headed and is isnt down the sup32 route...
 
You highlighted the sup32 has TCAM limitations - does this apply to the sup720-3B as well ??  From what other list memebers have said were looking at around 200k prefixes currently - so the sup32 would be able to handle this (at the moment) - however, not fully understanding the current growth of the internet (in terms of prefix saturation) - it would be difficult to say the sup32 would be good for the next few years (unless Cisco improve the sup32 - does anybody know if this is this likely or indeed possible).
 
Im getting some good pricing on the sup720-3BXL - so I think barring any feedback that tells me to avoid the 3BXL at all costs, I will go with this.
 
Again thanks for your time in replying.
 
Alex

As others have said, you should go the the Sup720-3BXL because of
the TCAM limits of the Sup32, which can 'only' be tuned to 239k
prefixes.

Other differences:

Sup32 has eight on-board GE ports, slightly better queueing and
scheduling on the uplink ports, two USB ports, and more onboard
flash.

The Sup720 has a 360 Gbps switching fabric (the 32 has only a 16
Gbps shared bus), supports distributed forwarding for a total of
400 Mpps, and has a slightly more powerful router CPU. It is sold
with a base ($0) license for IP Services vs IP Base on the Sup32
(10 k$ diff).

The Sup720 also supports the new high-density, high-performance
modules in the 67xx series, such as 6724 (15 k$ for 24 ports and
20Gbps) or the 6748 (20k$ for 48 ports and 40 Gbps) vs 6516A (15
k$ for 16 ports and 8 Gbps).

The PFC on the Sup720 is also field-upgradable, so one can swap
the PFC3B for a PFC3BXL (or PFC3CXL, when time comes). Whether
the same will be possible for the Sup32 remains to be seen.


In *my* opinion, the Sup32 makes little sense. But they ship lots
of them, so I guess other people see this differently.
