Assigning a PE ID that has been taken

Follow these steps to assign a different PE unit a PE ID that is already taken.

Note: Re-configuring a PE to use an existing PE ID may cause traffic interruption if the module and port configurations or the port connections do not match.

  1. Physically disconnect the PE units to be changed.
  2. Remove the pe-id configuration from the affected PE units, and reconfigure them using pe-id configurations that work with the new IDs.
  3. Execute the write memory command to save the new pe-id configurations.

The following example reconfigures two PE IDs when PE unit 17 and PE unit 18 have been manually swapped, so that port 1/1/3 becomes associated with PE 17, and port 1/1/6 becomes associated with PE 18.
