Lost Console Access on HP 10508

Lost Console Access on HP 10508

We have two HP 10508 switches in IRF.

 

Yesterday, I was only able to get console access through one of the many management ports.

 

I was able to input a bunch of configuration.

 

Towards the end, I submitted:

 

user-interface aux 1/0 2/1
idle-timeout 5 0
user-interface vty 0
authentication-mode scheme
user privilege level 3
set authentication password cipher <snip>
idle-timeout 15 0
protocol inbound ssh
user-interface vty 1 15
authentication-mode scheme
user privilege level 3
set authentication password cipher <snip>
idle-timeout 5 0
protocol inbound ssh

 

Things still seemed okay at that point.

 

After that, I entered:

public-key local create rsa

And this is when the console stopped responding.

 

Interestingly, it doesn't seem like the switch is down, because fortunately I was able to get enough configuration on it that I am able to still access it via SSH.

 

Anyone have any idea why I no longer get any response when connecting through serial console?

 

We have ruled out the serial cable, as it still works perfectly fine with our other HP switches.

Please let me know if there is any other config that I should provide.

 

Thanks!
