Cisco 837 IOS update query. Novice at large.

[darragh]

Hello, Can anyone tell me what image I can safely update my Cisco 837 with? It is currently running c1700-k9o3sy7-mz.122-13.ZH.bin. I am having issues with my ISP and they are refusing to talk to me unless I have the latest image. Please help.

Interesting, you are currently running an image designed for the 1700 :)

According to software advisor, you should install c837-k9o3sy6-mz.12.4-9.T1 for your 837 Cisco.

Sorry. Dialed into my 1700 doing something else. The image on the 837 is c837-k9o3y6-mz.123-2.XC.bin.

That is great. Thanks. Just to clarify. If I install that image do I still have access to all of the features that we currently have. What I want to know is, does one image contain enhanced features that another doesn't?

Issue resolved.

Darragh,

Can you post the

output ?

There are some memory requirements for different IOS. The T version I suggested requires 64MB Flash.

The IOS you just posted only requires 32MB Flash since it's not running the 'PLUS' option.
