3.2 Configuration Scheme
For the hosts in VLANs are seperated at layer 2. To make it possible for these host to
access the internet, we need to configure a VLAN interface on the switch for each VLAN.
The VLAN interface can be considered as the default gateway for the hosts in the VLAN.
All the requests to internet are sent to the VLAN interface first, then the VLAN interface will
forward the packets to the internet according to the routing table.
Demonstrated with T1600G-28TS, this chapter provides configuration procedures in two
ways: using the GUI and using the CLI.
3.3 Using the GUI
For the configurations for all the VLANs are similiar, here we only take the configuration of
VLAN interface for VLAN 2 as an example.
