The value of aluLcrStatusMcCtlLinkState indicates the current state of the Multi-Chassis (MC) LCR Group Control Link. Note that for a Single-Chassis LCR group the state is always up. The state 'up' indicates that the MC-LCR controller has received a valid control message from its neighboring router within the last aluLcrConfigMcHoldTime interval, and the MC-LCR control link is considered as operational. The state 'downSignalingFailure' indicates that the MC-LCR controller hasn't received any control message from its neighboring router or vice-versa within the last aluLcrConfigMcHoldTime interval. The MC-LCR control link is considered as operationally down. The state 'downIncompatibleNbr' indicates that the MC-LCR controller has received a control message from a neighboring router within the last aluLcrConfigMcHoldTime interval, but the member type (i.e. working/protection) of the neighboring router is not compatible with that of the local router. The MC-LCR control link is considered as operationally down.
