ISIS-STD_1.3.6.1.2.1.138.0.2 isisManualAddressDrops

Description

ISIS-STD/2/MANAREA_DROP:OID [oid] Some area addresses were discarded because the number of area addresses exceeded three. (ManAreaAddr=[opaque])

On a Level-1-2 wireless access controller, IS-IS leaked Level-1 area addresses to the Level-2 area, increasing the area addresses of the Level-2 area to more than 3. In this case, IS-IS used the top three smallest area addresses as the Level-2 area addresses, causing address loss in the local Level-2 area.

Possible Causes

On a Level-1-2 wireless access controller, IS-IS leaked Level-1 area addresses to the Level-2 area, increasing the area addresses of the Level-2 area to more than 3. In this case, IS-IS used the top three smallest area addresses as the Level-2 area addresses.

Procedure

  1. Run the display isis lsdb level-1 verbose command to view details about the Level-1 LSDB. Based on the information about the AREA ADDR field in the LSP with the fragment number being 0, you can determine whether the number of Level-1 area addresses is greater than 3.

    • If the number of Level-1 area addresses is greater than 3, go to Step 2.
    • If the number of Level-1 area addresses is not greater than 3, go to Step 3.

  2. Run the display isis lsdb { level-1 | level-2 } verbose command to check whether the Level-1 area addresses are the same as the Level-2 area addresses in the LSPs with the fragment number being 0 on the local wireless access controller.
  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
