Getting MAC address from physical adapters

Command

wmic nic WHERE "PNPDeviceID LIKE '%PCI%' AND ProductName LIKE '%Wi%'" GET MacAddress | findstr /C:":"

Command Anatomy

wmic - Windows CLI legacy tool for accessing WMI data
nic - The alias of the WMI class we are querying
WHERE
PNPDeviceID LIKE '%PCI%' - Find results from the PNPDeviceID column that has the string 'PCI' anywhere in the string. Determines if device is a physical PCI device.
AND
ProductName LIKE '%Wi%' - Find results from the ProductName column that has the string 'Wi' anywhere in the string. Determines if device is a wireless adapter.
GET
MacAddress - The column we want results from
|
findstr - The find string command. WMIC returns results with headers and we are doing this to get only the MAC address without the header so we can directly return the result to the VSA agent procedure through #global:cmdresults#
/C:":" - Specifying the pattern to the findstr command. ":" tells findstr to look for a colon.

Limitations

Doesn't cater to USB devices
Can break the agent procedure for machines with multiple physical devices (eg. Dual LAN)
