Chapter 1 VLAN Configuration
4-4
VLANs can share a same network segment. Thus, users can share the same IP
address of the gateway.
VLAN aggregation is realized by performing Address Resolution Protocol (ARP)
Proxy over IP addresses of various VLANs.
Caution:
Do not use VLAN aggregation on interconnecting of layer3 equipment because it may
create various useless protocol control packets.
1.2 Configuring VLAN
VLAN can be used only on the Ethernet sub-interface or GE Ethernet sub-interface.
When configuring VLAN, do as follows:
1)
In routing mode
z
Creating a sub-interface
z
Assigning the IP address to the sub-interface
z
Setting the encapsulation type and associated VLAN ID for the sub-interface
2)
In transparent mode
Only high speed interfaces, such as, 8FE interfaces and GE interfaces, support the
transparent mode.
When configuring the relevant VLAN, do as follows.
z
Creating a VLAN and entering VLAN view
z
Entering VLAN interface view when a VLAN is created
z
Adding or deleting a port
z
Configuring a Trunk port
3) In
composite
mode
Only high speed interfaces, such as, 8FE interfaces and GE interfaces, support the
transparent mode. Use the
portswitch
command in interface view to switch the
interface to the transparent mode.
For VLAN configuration of interfaces working in transparent mode, refer to 2).
For VLAN configuration of interfaces working in routing mode, refer to 1).
You can use the
ip address
command in interface view to assign the IP address to
the sub-interface.
For this command in detail, refer to
"05-Network and Routing Protocol Operation"
in
this manual.
