Cisco Catalyst 2960-24TT-L Switch

Hi everyone,

I have the above mentioned Cisco switch. I am interested in knowing the IP address or the assigned name of devices connected to its individual ports. I am not interested in changing any of the switch's or port's properties.

1Q) Can someone please tell me which Cisco application I can use for this?

2Q) Is there any specific port of it that I can or cannot connect to for this purpose?


Thank you and Happy Thanksgiving,

@neilmehta42969453 , Hello!


There are some resources on your own switch that can help you.


Firstly enable this resources whether are disabled.


CDP: Cisco properties

LLDP: Standard Devices

sw(config)# cdp run

sw(config)# lldp enable


they will show to you directly device connected (hostname, ip address, platform and others).

command that can be used:

show cdp neighbors

show cdp neighbors detail

show lldp neihbors

show lldp neighbors detail


There are others commands, check it:




Other resource that you can use is the entry arp. 

show arp will show to you information about mac and ip address learning on each interface.

Re: Cisco Catalyst 2960-24TT-L Switch

on the switch (L2 device) issue the command "show mac address-table"

-> capture the output to record what mac address is connected to what interface

on your router (L3 device) issue the command "show ip arp" (could be this same switch?)

-> capture the output to record the relation of MAC-addresses and  IP-addresses


in a spreadsheet sort both lists on mac address and match both lists 

-> result is a combined list "MAC - IP - port"

If that is something you want to or need to check more often,
maybe consider enabling DHCP Snooping (if you haven't already).

If you have - you will be able to find MAC Address and IP Address of all connected Clients which obtain their IP Address over DHCP.

Best regards

Thank you so much for your reply. Which software do I need to issue these commands? GNS3 or Cisco Packet Tracker?
