Method 2: Allow suggested ID or previous unit ID assignment

  1. Disconnect PE units 18 and 19 from the CB.
  2. On the CB, remove pe-id configuration for units 18 and 19 from CB port 1/1/10.
    Note: You must retain pe-id configuration for PE unit 17 because it is still connected to the CB. If you try to remove it, the system blocks the command. 
    ICX7650-48F Router# configure terminal
ICX7650-48F Router(config)# spx cb-config
ICX7650-48F Router(config-spx-cb)# pe-id 1/1/10 17

  3. On the local console for PE units 17, 18, and 19, remove the suggested ID if it is different from the previous assigned ID. If it is the same, you can remove it or keep it. The CB ID assignment will be based on the suggested ID or the previous ID.
  4. Connect PE unit 18 to SPX port 1/1/5 and PE unit 19 to PE 17 on SPX port 1/1/10 as shown in the CB configuration on the right in the previous figure.
    The CB assigns PE units 18 and 19 the desired ID, either based on the suggested ID that is configured or based on the unit's previous ID.
  5. Enter the write memory command to save the configuration. 
    ICX7650-48F Router(config-spx-cb)# exit
ICX7650-48F Router(config)# exit
ICX7650-48F Router# write memory
