User's Manual 11. Network
Parameter Description
[VLANNativeVLANID]
sent only with a priority tag (VLAN ID = 0).
When the Native VLAN ID is equal to one of the VLAN IDs listed in the
Multiple Interface table (and VLANs are enabled), untagged incoming
traffic is considered as incoming traffic for that interface. Outgoing traffic
sent from this interface is sent with the priority tag (tagged with VLAN ID
= 0).
When the Native VLAN ID is different to any value in the 'VLAN ID'
column in the table, untagged incoming traffic is discarded and all
outgoing traffic is tagged.
The default Native VLAN ID is 1.
Note: If this parameter is not configured (i.e., default is 1) and one of
the interfaces has a VLAN ID set to 1, this interface is still considered
the ‘Native’ VLAN. If you do not wish to have a ‘Native’ VLAN ID and
want to use VLAN ID 1, set this parameter to a value other than any
VLAN ID in the table.
11.3.1 Assigning NTP Services to Application Types
You can associate the Network Time Protocol (NTP) application with the OAMP or Control
application type. This is done using the EnableNTPasOAM ini file parameter.
11.3.2 Multiple Interface Table Configuration Rules
The Multiple Interface table configuration must adhere to the following rules:

Each interface must have its own subnet. Configuring two interfaces with addresses in
the same subnet (e.g., 192.168.0.1/16 and 192.168.100.1/16) is invalid.

Subnets of different interfaces must not overlap (i.e. 10.0.0.1/8 and 10.50.10.1/24 is
invalid); each interface must have its own address space.

Each interface must be assigned a unique IP address (i.e., two interfaces may not
share the same address space, or even part of it).

The prefix length replaces the dotted-decimal subnet mask presentation and must
have a value of 0-30 for IPv4 addresses.

Only one OAMP interface must be configured and this must be an IPv4 address. This
OAMP interface can be combined with Media and Control.

At least one Control interface must be configured with an IPv4 address.

At least one Media interface must be configured with an IPv4 address. .

The network interface types can be combined:
• Example 1: One combined OAMP-Media-Control interface with an IPv4 address
• Example 2:
♦ One OAMP interface with an IPv4 address
♦ One or more Control interfaces with IPv4 addresses
♦ One or more Media interfaces with IPv4 interfaces (with VLANs)
• Example 3:
♦ One combined OAMP-Media interface with an IPv4 address
♦ One or more combined Media-Control interfaces with IPv4 addresses.

Each network interface can be configured with a Default Gateway. The address of the
Default Gateway must be in the same subnet as the associated interface. Additional
