The M160 always shipped with IPII, also known as the CF chip. The C if the
internal name for the Internet Processing ASIC. The "F" does indicate
filtering capability.


A show chassis hardware should confirm IP III.

there should be no difference and usually CF are internal
names. we use the term Internet Processor 2 version 1 or
version 2 which is the CF and yes F stands for Filter and the
Internet Processor IP1 was the first one we shipped. The C is
just the Alphabet. With the show chassis hardware all would be
clear.

Hrmmm.

In a show chassis sfm detail, both the CF and non-CF show:

Total CPU DRAM 64 MB
Total SSRAM 8 MB
Internet Processor II Version 1, Foundry IBM, Part number 9

In a show chassis hardware, they show:

SFM 0 SPP REV 07 710-001228 xxxxxx
SFM 0 SPR REV 05 710-002189 xxxxxx Internet Processor IIv1
SFM 1 SPP REV 07 710-001228 xxxxxx
SFM 1 SPR REV 05 710-002189 xxxxxx Internet Processor IIv1
SFM 2 SPP REV 07 710-001228 xxxxxx
SFM 2 SPR REV 04 710-002189 xxxxxx Internet Processor IIv1
SFM 3 SPP REV 07 710-001228 xxxxxx
SFM 3 SPR REV 05 710-002189 xxxxxx Internet Processor IIv1

0 and 1 are CF, 2 and 3 are non-CF. Same part numbers, one has a lower
revision on the SPR but the other non-CF has the same revision as the
rest.

Richard,
all 4 SFM's are the same type. So there is no single
difference at all apart form the Label. I remember we
were trying to remove any indication to
internal's which is just confusing like it did for
you.

All internet processor II chips are considered CF. There are two version of
the IP II. I believe the latter is an enhanced IP II, which is normally
associated with an Enhanced system board. The version 2 has more memory and
a faster clock rate.
