How to get mac address value from device via SNMP in powershell?

Question

PowerShell

Can't get mac address value via snmp using powershell.

$SNMP = new-object -ComObject olePrn.OleSNMP
$SNMP.open($IP,"public",2,6000)
$mac = $SNMP.Get('.1.3.6.1.2.1.2.2.1.6.1')

$mac.lenght = 0
If you go through the tree (two network interfaces - two macs, one can be empty for loopback), then, according to the documentation, you should get a two-dimensional array of OID - value

$SNMP = new-object -ComObject olePrn.OleSNMP
$SNMP.open($IP,"public",2,6000)
$mac = [System.Text.Encoding]::Default.GetBytes($SNMP.GetTree('.1.3.6.1.2.1.2.2.1.6'))
[System.Text.Encoding]::Default.GetString($mac)

returns: interfaces.ifTable.ifEntry.ifPhysAddress.1 interfaces.ifTable.ifEntry.ifPhysAddress.2, only OIDs, no values.

Third-party software, such as snmpGet, or MIBBrowser mac in that OID sees the norms

OID=.1.3.6.1.2.1.2.2.1.6.1
Type=OctetString
Value= 00 C0 EE 3A 77 89
