Error description

• In an environment that has a F5 hardware load balancer
  connected  to a Huawei NE40E router. Both device has been
  enabled snmp discovery, when trying to get these two elements
  stitched via the LLDP protocol(cross domain) and have enabled
  both DefaultLLDP and  LLDP agents in ITNM, also confirmed that
  LLDP has been enabled  on the Huawei router and it can see the
  F5 as it's LLDP neighbor.
  
  However F5 Device is not stitched to Huawei NE40E router using
  LLDP.

  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The layer 2 topology may be incorrect because LLDP links can *
  * be left unresolved if the device at one end of an LLDP link  *
  * isn't discovered by an LLDP agent.                           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Upgrade to  fix pack 4.2.0-ITNMIP-FP0002                     *
  ****************************************************************
  

Problem conclusion

• Fied in fix pack 4.2.0-ITNMIP-FP0002.
  The LLDP stitcher can now use non-LLDP data to resolve links
  (e.g. sysName). This results in a more complete layer 2 topology
  in cases where the LLDP agents may not have discovered both ends
  of a link.
