4. Use the MAC address of the channel (
) associated with the
VLAN.
Consider the sample configuration in
. When all interfaces get their MAC
address automatically, interface vlan1 inherits the MAC address of port 1, vlan2
inherits its MAC from port 4, vlan3 from port 7 (assuming port 6 is tagged on
VLAN 3), and interface vlan4 from port 10.
Note
For the automatic MAC assignment methods (steps
above), the MAC ad-
dress may change when the set of ports associated with the VLAN changes.
When this happens, the WeOS device will submit a gratuitous ARP to update
stale ARP caches in neighbour nodes.
For VLANs created dynamically (
), no associated network interface
is created. Thus, for such VLANs no interface MAC address is needed.
19.2.5
IP address settings
Each network interface can be assigned a primary IP address and up to 8 sec-
ondary IP addresses, this is sometimes referred to as multinetting, but can also
be another address on the same subnet as the primary address. The primary IP
address can either be statically or dynamically assigned, depending on the ad-
dress method configured for the interface (”inet static” or ”inet dynamic”).
The secondary IP addresses can only be statically configured, but can be used
with both static and dynamic primary address.
Options for configuring the primary address for different interface types:
❼ VLAN interfaces: The primary IP address of a VLAN interface can be config-
ured statically, or configured to acquire its address dynamically (DHCP). It is
also possible to have a VLAN interface without any IP address.
❼ PPP interfaces: For PPP interfaces the address setting is set to dynamic, but
the actual IP address assignment is handled by the PPP configuration (IPCP),
see
❼ GRE interfaces: For GRE interfaces, the primary IP address can only be con-
figured statically.
❼ Loopback interface (lo): The primary IP address of the loopback interface
(lo) is permanently set to 127.0.0.1.
