Note to Self:

If an administrator has setup your Nokia (IPSO) shell account to log into clish rather than the unix shell... and you need to cpstop;cpstart... you can switch shells with the command...
Nokia:>shell [admin@nokia]#
It's quite a simple command, so why can't I remember it!

Footnote:
iclidis the "router shell" - where you can do show commands
clishis the "voager shell" - where you can "set" things and make changes
/bin/sh or Bourne shell (or sh) is the "Unix shell" - where you have access to the root operating system and can make changes to the file-system or restart processes.
