  • Page 46 Configuring LIM and LIM Port Redundancy Configuring LIM port redundancy Parameter Specifies Enables or disables port redundancy and specifies the mode. You can sparing-mode enable two port-redundancy modes. The default value, inactive, disables LIM port redundancy. The manual setting deactivates the LIM port and then reestablishes the connection on the same port of the spare LIM.
  • Page 47 Configuring LIM and LIM Port Redundancy Configuring LIM port redundancy stops. You can restart the process by resetting the system or by setting the sparing-mode parameter to inactive and then back to automatic. The parameters used for automatic LIM port redundancy are found in the Auto-LIM-Sparing-Config subprofile of the LIM-Sparing-Config profile for the spare LIM of the same type.
  • Page 48 Configuring LIM and LIM Port Redundancy Configuring LIM port redundancy Parameter Indicates State of the redundancy function. If redundancy is not sparing-state enabled, sparing-none is the value. If redundancy is enabled and the LIM slot is a primary LIM, the value can be primary-active or primary-inactive.
