Re: Procurve 2824 not showing IP address
No, I haven't had time to run that command.
Let me be see if I understand it properly, so to find out the IP addresses of the devices connected to a switch, I have to ping all the ip addresses from the CLI.
So if the range is 192.168.100.x - 192.168.100.y, do I have to ping all the IP addresses in that range? And then run the 'show arp' command to find out the IP addresses. Am I correct?
And this is just one switch, I have 5 other switches in different buildings.
Thank you.

Re: Procurve 2824 not showing IP address
It's not really that straightforward. You can find the hardware (MAC) addresses of individual devices with "show mac " or "show mac mac-address".
To map individual IP address to MAC addresses, you can PING the node and then show arp. Or you could extract the information from your DHCP server.
You might want to look at a network management tool like Netdisco, although that might be overkill for your requirements.

Re: Procurve 2824 not showing IP address
Yes, that is exactly what I am looking for.
One thing I noticed on your example is that the port type is 'dynamic'. From what I understand, it is the VLAN type? If it is so,
how do you change the VLAN from static to dynamic because I just checked and on my switch the VLAN type is static. Could it be one of the reason because the VLAN type on my switch is static.
Thank you.
