Only need to modify this:
$Tlv = @{
0x0001 = 'Device'
0x0002 = 'IPAddress'
0x0003 = 'Port'
0x0006 = 'Model'
0x000A = 'VLAN'
0x0016 = 'Management'
}

$TypeString = 0x0001, 0x003, 0x006

to This:
$Tlv = @{
0x0001 = 'Device'
0x0002 = 'IPAddress'
0x0003 = 'Port'
0x0005 = 'Software'
0x0006 = 'Model'
0x000A = 'VLAN'
0x0016 = 'Management'
}

$TypeString = 0x0001, 0x003, 0x005, 0x006

Tested... works great!
