If you are logged in, then you are on the active RSP.
So, you can do a "show version" from there.
The uptime shown is the one of the RSP.
From what I remember, the uptime shown there is not affected by
VIP crashes or RSP-RESTART (Cbus complex and the like).
Only a reload or power-on have I seen to make a difference.
You can also try a "show diag", to see if there is more information there
about recent crashes.
If you want to connect to any of the VIP cards,
there is the hidden (and therefore not supported) "if-con ".
You use "if-quit" to quit the session.
I think this doesn't work for an RSP slot.
