be named according to their associated instance ID, e.g., pppoe0 is the interface
of PPPoE instance ”0”, modem0 is the interface of serial/modem instance ”0”,
and so on.
To communicate with the switch via a newly created interface, an IP address must
be assigned to the interface, see
When creating a PPP instance of type PPPoE, the admin distance and manage-
ment interface properties of the associated VLAN network interface are inherited
by the PPP interface. This inheritance does not work in the reverse direction
though, i.e., if the PPP instance is removed, the management and admin dis-
tance properties of the PPP interface are not passed back to the associated VLAN
interface.
Note
With PPPoE, one must specify which VLAN interface to run PPPoE over, e.g.,
see interface vlan4 in
. The resulting PPP interface will be said to
”own” the associated VLAN interface. As of WeOS v4.17.0, it is not possible
to access a switch via ”owned” VLAN interfaces — access is only possible
via the PPP interface.
19.2.4
VLAN Interface MAC address
Each VLAN network interface will be assigned a MAC address (also known as
the Ethernet address, the link address, the hardware address, or the IEEE EUI-48
address).
In WeOS products, each Ethernet port (or DSL port) is assigned a MAC address,
and a VLAN interface will by default inherit its MAC address from one of its mem-
ber ports. It is also possible to manually configure a MAC address for a VLAN
interface.
The algorithm to assign VLAN interface MAC address uses the following prefer-
ence order:
1. If the interface has been configured with a custom MAC address, use that
address as the interface MAC address.
2. If the VLAN has one or more ports assigned untagged, use the MAC address
of the ”lowest” untagged port as the interface MAC address.
3. If the port has one or more ports assigned tagged, use the MAC address of
the ”lowest” tagged port as the interface MAC address.
