I am new to Cisco routers. I just bought a used 837, managed to configure it and it is working fine. Its IOS is an older version and wont work with the latest SDM. Is there a version of SDM which will work with my 837's IOS version?
Or maybe I should upgrade the IOS but later IOS versions I have seen require larger memory than my 837. Does anyone know of an IOS which will work with SDM and which will work with the memory level of my 837?
Currently my 837 has:
IOS (tm) C837 Software (C837-K9O3Y6-M), Version 12.2(8)YN, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1) Synched to technology version 12.2(11.2u)T
