HP 2510G-48 identify the devices connected to the switch via SNMP

[mniuuum]

Hi, this is my first post so sorry for any mistakes i can take.

I have a switch HP 2510G-48 ports. I want to identify the connected host via MIB or OID. I need somethening like mac address or IP address or hostname. I cant get it via snmp. I only see mac address card but the MIB name/OID is changing 0.o
For one address card its .1.6.x.x.x.x. for another its .1.9.x.x.x.x. 
For example im now monitoring incoming traffic ports and the oids are clear to read. For example  .1.3.2.1.2.1-.1.3.2.1.2.48.  How i can get the true OID's to identify connected hosts to the switch. Please help i will be grateful. I attach the screenshoot.

I want to know what mac-addres is in specify port. For example mac: 00:00:00:00:00:00 on port 28. Incoming ocects just have oids 1.3.2.1.2.28 
And i know that's 28th port.
