With the introduction of the NX-OS like CLI Cisco also added the option to run commands on the switches directly from your apic. It’s now even easier to get some infos from one or multiple switches in your fabric.
Show switchname on a single fabric switch
apic1# fabric leaf01 show switchname ---------------------------------------------------------------- Node 101 (leaf01) ---------------------------------------------------------------- leaf01
You can also run commands on multiple devices
apic1# fabric leaf01, leaf02 show switchname ---------------------------------------------------------------- Node 101 (leaf01) ---------------------------------------------------------------- leaf01 ---------------------------------------------------------------- Node 102 (leaf02) ---------------------------------------------------------------- leaf02
The list of possible commands is pretty long, just to give an idea
