This counts Force Switch RAPS PDUs this node has transmitted out its west link, meaning a force-switch command was issued locally on this node or this ring segment and is being announced to the rest of the ring. This confirms that a force-switch condition originates from this specific device, which matters when an admin needs to know which device to actually issue the clear command on, rather than clearing a setting on a downstream node that's merely relaying the state. For example, if an admin runs a force-switch command on this device's west link for maintenance, this counter's steady increase confirms the command is actively being announced onto the ring for as long as it remains active.
