    Description

      I have some TP-Link switches and JetStream 24-Port Gigabit L2+ Managed Switch with 4 SFP Slots. LLDP neighbors shows wrong localport information.

      Local ports shold be different. In this case Gigabitethernet1/0/27 and Gigabutethernet1/0/28

          yah, seems as device have trouble with walking. try little different snmpwalk command:

          snmpwalk -v2c -c <community> -t 2 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk
          

          There added options for increase timeout and '-Cc' for error 'Error: OID not increasing'
