Locating a Host Port by IP Address in Juniper

How to find the system connected to a particular port, if IP address is known.

If we need to troubleshoot the remote network and we have only ip address of the machine is known,and since some specific services are not running on a particular vlan and there is requirement of change in vlan.
Then we need to identify the connected switch port which we can not find without mac-address or physical tracing.Then in juniper we have an options for that, the command is

Let us assume IP given is 172.17.140.143    
sh lldp neighbors
Outpout:
root@Hitesh-SW2> show lldp neighbors
Local Interface    Parent Interface    Chassis Id          Port info          System Name
ge-0/0/47.0        -                   00:1c:2e:1a:52:80   3                  hiteshpc
ge-0/0/38.0        -                   0.0.0.0             SW Port            SEP405539AD2574.
ge-0/0/10.0        -                   172.17.140.79       SW Port            SEP2C3ECF7B73AF.corp.local
ge-0/0/1.0         -                   172.17.140.124      SW Port            SEP2C3ECF7B8A19.corp.local
ge-0/0/4.0         -                   172.17.140.143      SW Port            SEP70CA9B997C5F.corp.local
ge-0/0/3.0         -                   172.17.140.161      SW Port            SEP70CA9B997EA0.corp.local
ge-0/0/2.0         -                   172.17.140.202      SW Port            SEP70CA9B997CD5.corp.local
ge-0/0/7.0         -                   172.17.140.206      SW Port            SEPE8B748EEC46F.corp.local
ge-0/0/11.0        -                   172.17.140.210      SW Port            SEPE8B748EEC470.corp.local
ge-0/0/15.0        -                   172.17.140.213      SW Port            SEPE8B748EEC3AB.corp.local
ge-0/0/17.0        -                   172.17.140.215      SW Port            SEP30E4DB825B42.corp.local
ge-0/0/14.0        -                   172.17.140.216      SW Port            SEP70CA9B997EED.corp.local
ge-0/0/12.0        -                   172.17.140.217      SW Port            SEP30E4DB8256EB.corp.local


Then from the above command we will trace the interface and once interface is located, we can change the respective vlan.

Since ge-0/0/4 is a abc vlan member and we need to change it to a member of vlan xyz.we then need to give following commands.

Command to check the interface vlan
root@JUN-L2-365-BF-SW2> show vlans
Name           Tag     Interfaces
abc          138
                       ge-0/0/4.0*
xyz          139
                       ge-0/0/14.0*, ge-0/0/47.0*

Process to change the vlan from abc to xyz.

step 1. Delete interface from vlan abc

delete interfaces ge-0/0/4 unit 0 family ethernet-switching vlan members abc

step 2. Add interface to vlan xyz

interfaces ge-0/0/4 unit 0 family ethernet-switching vlan members xyz
