Proper way to exit vconsole whilst nested

Hi Experts,

our Avocent terminal servers establish console access as telnet sessions - in this case, to vCMP Host. BIG-IP vconsole is itself a telnet session to vCMP Guest. So, together, it's a nested terminal session and pressing '^]' shows outer session options (ie. Avocent) instead of inner (vconsole).

What is the graceful method to terminate vconsole and return to vCMP Host - killing telnet session (as question about vconsole utility) doesn't feel right?

R's, Alex
