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.
