IV78068: USE ALTERNATE MIB TO DISCOVER CISCO ROUTER TO HP SWITCH CONNECTIONS WHEN LLDP IS NOT ENABLED ON CISCO

7.2.2-TIV-ITADDM-FP0005

APAR status

• Closed as program error.

Error description

• In cases where a customer sets the property to filter the
  redundant FDB MAC found on trunk port of any switches, we
  require that LLDP and CDP be available on the network devices.
  However, in some cases only CDP may be enabled on Cisco
  while LLDP is enabled on the HP switches. If this occurs, then
  relationships between the two are not discovered.  We have
  founb that there are alternate MIBs that can be used in this
  case and will add these as a backup option;
  
  From LLDP enabled switch;
  
  LLDP-MIB::lldpRemChassisId.0.2.1 = STRING: "<CISCOROUTER>"
  
  
  LLDP-MIB::lldpRemPortId.0.2.1 = STRING: "GigabitEthernet0/1"
  
  From CDP enabled Cisco device;
  
  SNMPv2-SMI::enterprises.9.9.10.1.1.4.2.1.1.5.1.1.2 = STRING:
  "<CISCOROUTER>"
  SNMPv2-SMI::enterprises.9.9.23.1.3.4.0 = STRING: "<CISCOROUTER>"
  

Local fix

• enabled LLDP on all network devices
