VLAN
Typical VLAN
Configuration Example
In as Ethernet interface is connected with a LAN Switch port. As the Ethernet
subinterface of every specified VLAN ID can act as an independent gateway, this
subinterface and other Ethernet subinterface in the same VLAN ID should belong
to the same subnet segment.
Please implement the following configuration under Ethernet subinterface view.
Table 364 Configure IP address of Ethernet subinterface
Operation
Configure IP address of Ethernet subinterface
Delete IP address of Ethernet subinterface
By default, no IP address is defined.
Ethernet subinterface acts as a gateway in VLAN and so the subnet number of its
IP address must be correct. The default gateway of LAN Switch ports that belong
to the same VLAN should be set as the IP address of this subinterface. Besides, the
IP address of Ethernet subinterface can be set only when this subinterface has
finished the configuration of VLAN ID.
