LLDP Behavior

PAN-OS specific behavior for the openconfig-lldp model.
Review the LLDP YANG deviation file before using the openconfig-lldp model to familiarize yourself with supported paths.
When using the LLDP model with PAN-OS firewalls:
  • Doing a Get on the lldp/interfaces path retrieves all consolidated information for the aggregated ethernet interface members and other interfaces.
  • You can direct gNMI calls to aggregate ethernet interfaces, but not to specific members of the aggregate interface.
  • When an interface has LLDP disabled, the interface counters are shown as all zeros.
  • Deleting an LLDP configuration will set the /lldp/config/enabled value back to false.
  • lldp/state/hello-timer is the transit interval in PAN-OS.
  • Below is the matching of counter from OpenConfig to PAN-OS at the lldp/interfaces/interface/state/counters level:
