Description: The value of tmnxEthRingCommandSwitch specifies the switch command to initiate on a path of an Ethernet Ring Group.

When read, this object returns the last command written or 'noCmd (0)' if no command has been written to this Ethernet Ring Group path since initialization. The return of the last command written does not imply that this command is currently in effect. The 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 tmnxEthRingPathRxApsPdu and tmnxEthRingTxApsPdu.

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 ring, regardless of the specified path. In addition, if tmnxEthRingRevertTime is a non-zero value (revertive mode) the active WTR (Wait To Restore) state is also cleared, or in the case of non-revertive mode, the command will trigger a reversion.

The 'clear (1)' command is only valid if at least one path is configured and either: 1. a local Forced Switch or Manual Switch command is in effect, or 2. a local Ethernet Ring Node is an RPL Owner Node and top priority request is neither R-APS (FS) nor R-APS (MS).

The value 'forceSwitch (2)' forces the specified path's tmnxEthRingPathFwdState to the 'blocked (1)' state.

The value 'manualSwitch (3)' sets the specified path's tmnxEthRingPathFwdState to the 'blocked (1)' state in the absence of a failure or forceSwitch. An inconsistentValue error is returned, otherwise.
