PAN-OS System Log - Max MIB size reached: LLDP neighbor addition failed...

L0 Member

Since upgrading to 9.0.X we have been seeing these messages in the system log:


subtype eq lldp

severity eq high

eventid eq 'too many neighbors'

description contains 'Max MIB size reached: LLDP neighbor addition failed for <REDACTED> on interface 715'


What do these messages represent?  Why are they a severity of "high"?  How do I resolve?



TIA for any thoughts and/or suggestions.

are you using lldp and how many neighbour devices are there supposed to be on the broadcast domain your interface is connected to?

you may need to disable lldp if you're not using it, or decrease your broadcast domain (by VLAN'ing) on your interfac so it only sees relevant neighbours
