Description: The value of tmnxEthTunnelApsCommandSwitch specifies the switch command to initiate on an Ethernet Tunnel APS Group.

When read, this object returns the last command written or 'noCmd (0)' if no command has been written to this Ethernet Tunnel APS Group 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. In order to determine the current state of the group it is necessary to read the objects tmnxEthTunnelApsRxPdu and tmnxEthTunnelApsTxPdu.

The value 'noCmd (0)' may not be used in a write command.

The value 'clear (1)' clears all the switch commands listed below for the specified member. In addition, if tmnxEthTunnelRevertTime is a non-zero value (revertive mode) the active WTR (Wait To Restore) state is also cleared.

The value 'lockoutOfSecondary (2)' prevents the primary (working) member from switching to the secondary (protection) member. The specified member should be the secondary member index, otherwise an inconsistentValue error is returned.

The value 'forceSwitchPrimaryToSecondary (3)' switches the primary member to the secondary member. If the secondary member is specified an inconsistentValue error is returned.

The value 'manualSwitchPrimaryToSecondary (4)' switches the specified primary member ot the secondary member. If the secondary member is specified an inconsistentValue error is returned.

The value 'exercise (5)' exercises the protocol for a protection switch of the specified member by issuing an Exercise request for that member and checking the response on the APS member.
