what's the best way of discovering all the wired Clients on a LAN, please?
i have Discovered all the Switches on the LAN, and Catalyst Center has picked up all the config of the Cisco network Devices, although the 360 views don't show me attached clients. However the Discovery Tool looks like it's for Network infrastructure only. the wizard states that 'this workflow is used to discover Cisco Network Devices. Third party devices can be manually added in the inventory page.'
i discovered the WLC infrastructure, and when i turned on netconf it pulled in all the wireless clients.
however i can't find any documentation about the best way to view all the wired clients including hostnames of phones and workstations etc.

When you discover your switches with the default settings, you should see Cat Center apply IP Device tracking configs on the access interfaces. That will let you see clients in a few different ways.
1) In Device 360 (which you could get to by using the global search for a switch hostname), look at the topolgy diagram and click on the client list.
2) In the Client Health Dashboard you can filter in a bunch of different ways, by site (in the upper left corner of the page where it defaults to "Global", or by individual columns in the table (such as switch name).
3) In the Reports tool there is a Client Summary

thanks that's useful to hear about device-tracking. i didn't have any default IP device-tracking configs in Catalyst Center templates but i just added 2 policies directly to the config, one for access switchports and one for trunks which seem to do what i want.
device-tracking policy DISABLE-IP-TRACKING
trusted-port
device-role switch --To stop the creation of binding entries, you configure the device as switch
tracking disable
!
device-tracking policy IP-TRACKING
limit address-count 2 --Specifies an address count limit per port
security-level glean --Gleans addresses passively. this can be set to glean/guard/inspect
no protocol ndp
no protocol dhcp6
tracking enable reachable-lifetime 180 --Checks every 3 minutes for changes
i applied the policies to the ports on the switch and added the global device-tracking tracking command. now attached clients have started popping up in the 360 view, and health > wired client list
