    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

    c837-k9o3y6-mz.124-21a.bin:

    The PLUS image's file name is:

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

    Good luck
