I am a test engineer and I burn in a number of network appliances. They are tested for a few days and then move on and others are attached and burned in. I am using ssh to connect to the switch using the CLI. What commands should I be using to get the current list of attached devices? I need both IP addresses and host names.

 

Thanks,

Hmm... I do not think it is typical scenario for switches. If you use DHCP-server in your network, then it is better to check directly on dhcp-server. I can only think about show ip source binding to check ip/mac, only if dhcp snooping is enabled on your switch, while hostname.. I am not sure..

Hi Mitya,

 

My switch is the DHCP server on my network. Currenty I just show arp and ping -a 192.168.0.x each IP in the table to retrieve the hostnames. I am wondering if there is a more elegant way to do this.

Hi Viper00o

 

You also can use DHCP snooping to get the information. Then you can see the information on binding table.
