KB ID 0001110
After not touching one for a couple of years, I was back on HP switches recently, and I had to map out a clients switches. Now I could have used some software, but they didn’t have SNMP enabled so, I had to ‘re acquaint’ myself with LLDP.

To find what Port an IP address is on
First ping the IP address, to make sure that the switch has the MAC address you are looking at, in its ARP cache.
HP-Switch-1# ping 192.168.251.2
192.168.251.2 is alive, time = 3 ms
Then look for it in the ARP cache;
HP-Switch-1# show arp IP ARP table IP Address MAC Address Type Port --------------- ----------------- ------- ---- 192.168.251.1 e8b748-c757b0 dynamic 13 192.168.251.2 005056-a61c1c dynamic 5 << It’s on port 5 192.168.251.5 005056-a606d9 dynamic 7
Or if you already know its MAC address;
HP-Switch-1# show mac-address 005056-a61c1c Status and Counters - Address Table - 005056-a61c1c Port ------- 5
