Hello,
To get the Mac addeess, just remove the 01 off the front:
016c.b749.1645.a2 = 6cb7.4916.45a2
Hope that helps!

Hello
You could also check the arp table.
sh ip arp | in 10.220

Hi,
You have mentioned all MAC address in your post too.
Client ID: 0100.25ab.ac4s.57 == Mac address: 0025.abac.4s57
01 represents the Ethernet media type and the remaining bytes represent the MAC address of the DHCP client.
