Need to disable SSH version on a cisco 2600
We have a Cisco 2600 series router which is using SSH for remote access. WE had an outside firm do a security scan and they came back with some results including that I need to disable SSH version 1. I did some research and it seems that should be easy by simply putting in the ip ssh version 2 command, however that option is not available on my router IOS. When I type ip ssh ? the results do not show "version" as an option..Does anyone know how to disable SSH v1 when that command is not available...Here is my show ver:

You will need to upgrade your IOS to utilize ssh2
What is the model of your 2600?
the cisco feature navigator is the best place to find the IOS version you need

It looks like only the XM series routers support version 2 of SSH. So if you do not have an XM then you are doing the best you can :)

Its a 2621..I don't think its an XM series..So you think there is no IOS upgrade for that model that will solve the problem?
