SSH authentication - bad MAC #321

Description

Hi

Since Cisco implemented standard a higher MAC (Message Authentication Code) algorithms on their switches and routers on newer versions we get an error when trying to connect to these devices (BAD MAC). But when we try establish a manual SSH connection to these devices from the same server it works.

We can resolve this issue by lowering the MAC algorithms on those devices with the following command:

ip ssh server algorithm mac hmac-sha1 hmac-sha1-96

Is there anyone else with this problem? And is there a solution for this?

Thanks

Mark
