[CAUSE] The tmnxCpmNoLocalIcPort alarm is generated when the CPM cannot reach the other chassis using its local CPM interconnect ports. [EFFECT] Another control communications path may still be available between the CPM and the other chassis via the mate CPM in the same chassis. If that alternative path is not available then complete disruption of control communications to the other chassis will occur and the tmnxInterChassisCommsDown alarm is raised. A tmnxCpmNoLocalIcPort alarm on the active CPM indicates that a further failure of the local CPM interconnect ports on the standby CPM will cause complete disruption of control communications to the other chassis and the tmnxInterChassisCommsDown alarm is raised. A tmnxCpmNoLocalIcPort alarm on the standby CPM indicates that a CPM switchover may cause temporary disruption of control communications to the other chassis while the rebooting CPM comes back into service. [RECOVERY] Ensure that all CPM interconnect ports in the system are properly cabled together with working cables.
