Types Of Vlan; Configuring Basic Vlan Settings - 3Com 4500G Family Configuration Manual

The Ethernet II encapsulation format is used here. Besides the Ethernet II encapsulation format,
other encapsulation formats, including 802.2 LLC, 802.2 SNAP, and 802.3 raw, are also supported
by Ethernet. The VLAN tag fields are also added to frames encapsulated in these formats for VLAN
identification.
For a frame with multiple VLAN tags, the device handles it according to its outer VLAN tag, while
transmits its inner VLAN tags as payload.

Types of VLAN

You can implement VLAN based on:
Port
MAC address
Protocol
IP subnet
Policy
Other criteria
This chapter covers port-based VLAN, MAC-based VLAN, protocol-based VLAN, and IP-based VLAN.
You can configure the four types of VLANs on a port at the same time. When determining to which
VLAN a packet passing through the port should be assigned, the device looks up the VLANs in the
default order of MAC-based VLANs, IP-based VLANs, protocol-based VLANs, and port-based VLANs.

Configuring Basic VLAN Settings

Follow these steps to configure basic VLAN settings:
To do...
Enter system view
Create VLANs
Enter VLAN view
Configure a name for
the current VLAN
Configure the
description of the
current VLAN
Use the command...
system-view
vlan { vlan-id1 [ to vlan-id2 ] |
all }
vlan vlan-id
name text
description text
1-3
Remarks
—
Optional
Using this command can create multiple
VLANs in bulk.
Required
If the specified VLAN does not exist, this
command creates the VLAN first.
By default, only the default VLAN (that is,
VLAN 1) exists in the system.
Optional
By default, the name of a VLAN is its
VLAN ID, VLAN 0001 for example.
Optional
VLAN ID is used by default, for example,
VLAN 0001.
