It looks like without the command it defaults to 15%. Adding a 'memory-size iomem 5' doesn't seem to do too much... I think it still defaults to 15%

See if it works without the command. Bypassing the config via the
config register might do it too.

It's possible that FN is wrong. What feature set are you using? Do you
have 'memory-size iomem' configured on the router? Or something along
those lines, if memory serves me right (pun intended). I believe the
2600s and 3600s supported the command. Dedicating a large amount to
iomem might reduce the CPU memory to that which the router would find
insufficient.

Subject: [c-nsp] Memory requirements in Cisco Feature Navigator
I've got an IOS (12.3(14)T7) that I'm trying to load onto a 3640 router.
According to the feature navigator, it should require 96mb DRAM, 32mb
flash, which this router has. But, when I try to boot it, it gives me an
out-of-memory error and crashes during boot. Is the FN wrong, or is
there something I can do?
Thanks!

Hmmm. Running out of ideas. What if you take out the NMs, and then try
to boot it? If you can get it to come up, get a 'sho mem', and see how
much is left. It could be an error on the FN.

One: most people use a real name on the list.
Two: PPTP and PAT don't really mix. Read up on the PPTP protocol. If
not just try a whole bunch of PPTP clients behind a PAT. I don't
really value the PPTP protocol very highly.
Three: IPSec can do double NAT or double PAT (disguise the same
network at both ends)
Four: VPN for B2B implementations are better off if everyone insists
on publics for the interesting traffic networks, then each network
owner can NAT at their "demarc".
These are all things that are probably in the list archive.
I hope you got more replies than this, and in a kinder gentler tone,
but I'm in a hurry and didn't see anyone reply to you.

Wow. I must be imagining all this 10Gb Ethernet Cisco gear I'm looking
at. Nexus, 6500, etc. etc. DId you mean they aren't doing 10G CWDM
or DWDM?
The OP used 10GbE, but that could have been in error.

The OP was asking about a single-strand 10GE product, not just "any" 10GE
product, or even ordinary 10G DWDM products. Basically they're looking for
a 10GE version of 1000BASE-BX, an integrated mux+transceiver in a standard
pluggable package with a sigle strand connector, as desribed here:
http://www.cisco.com/en/US/prod/collateral/modules/ps5455/ps6577/product_data_sheet0900aecd8033f885.html
Everyone and their mother sells 10G DWDM gear (no CWDM though, probably
because dealing with the dispersion of a wider band signal at 10G speeds
is far harder than transmitting a narrow and stable 100GHz signal), but
that has nothing to do with what they wanted.
Also note as always that Cisco doesn't actually make any of this gear, nor
do they do anything even vaguely "different" or "interesting" with it.
This is all just trivial tuned optics and passive filters that you can get
from anyone (at better densities, with more channels, and with better
optical characteristics too), all Cisco does is slap their logo on it and
mark it up 10x.
