IOS 12.3(2)T 837

Could someone tell me how much memory is required to run IOS 12.3(2)T
on a Cisco 837. I only have guest access to Cisco. Apparently, Cisco
stopped including memory requirement on their release notes at some stage.
They say to use the configuration tool to check memory requirement
unfortunately guest logins cant access it.

My 837 has:

128k NV config memory
8192k processor board flash
2048k processor board web flash
32MB DRAM

Thanks

12.3(2)T isn't on their site anymore, but the newest 12.3 T train
requires 64mb (12.3.(14) I believe). The older ones may only require
32, but that was only IP/FW, all the IP Plus that I've seen require 48
to 64. So you might be able to swing 12.3(2), but probably not ip
plus.

AFAIR there was no 12.3(2)T for the 83x series router.
12.3(2)XA7 should run both IP/FW/3DES and IP/FW/Plus/3DES images on 837.
12.3(4)TPC11b, 12.3(4)T, 12.3(7)T IP/FW/3DES should run with 32MB only.

This router is EoS/EoL so why not go for a cheap 16MB DRAM upgrade on
ePay???
With 48MB RAM / and 12MB Flash it should run 12.4(21a) non PLUS images
nicely with "memory-size iomem 5".
Estimates from 836 brother.
No 837 here in Germany because all ADSL is AnnexB/ISDN even with POTS
telephone lines. The 837 images are slightly smaller than 836 because no
ISDN BRI support.

SDM can/should be installed locally on the PC, so no free flash is
needed. The flash is better used with external ADSL fw on todays DSLAMs.

I found some cheap 16MB DRAM and 4MB flash will try 12.4(21a) non PLUS if I
can find it. Do you happen to know what the file name is for 12.4(21a) non
PLUS and I will Google for it ??

Thanks

The PLUS image's file name is:

c837-k9o3sy6-mz.124-21a.bin

Good luck
