The value of vRtrGmplsCommandSwitch specifies the switch command to initiate on GMPLS LSP Path. When read, this object returns the last command written or 'noCmd (0)' if no command has been written to this GMPLS LSP Path since initialization. The return of the last command written does not imply that this command is currently in effect. This request may be preempted by a higher priority local or remote request. The value 'noCmd (0)' may not be used in a write command. The value 'clearLockout (1)' clears the lockout on the protection path. The value of 'forceSwitch (2)' switches the active path to the protection path. The value of 'manualSwitch (3)' switches the active path to the protection path. The value of 'revertSwitch (4)' switches the active path to the working path. The value of 'lockout (5)' prevents the working path from switching to the protection path.
