Below is a typical VLAN Discovery settings:
The VLAN_DHCP_STRING is a string to search for: Fx. VLAN_DHCP_STRING="iemen" will find a match
if the DHCP option string contains "Siemens" since the VLAN_DHCP_STRING is contained in the option
string.
The VLAN_DHCP_OFFSET is always calculated from the beginning of byte after the option.
Fx. 2B 01 0A 53 69 65 6D 65 6E 73 00 00 00 02 04 00 00 00 14 00 00 00 00 FF
VLAN_DHCP_OPTION=43: // to specify which option to look for
VLAN_DHCP_STRING="iemen" // to specify a string the match
VLAN_DHCP_OFFSET=14: // to specify a offset to where to start reading the VLAN ID
VLAN_DHCP_TYPE=0 // to specify whether the VLAN ID is in 0=HEX or 1=ASCII format.
VLAN_DHCP_LENGTH=4 // to specify the length of data should be collected to the VLAN ID
