CHAPTER 3
VLAN CONFIGURATION
This chapter describes how to set up the switch for local or remote
management, and the VLAN Local Management screens used to create
and configure VLANs in a SmartSwitch.
3.1 MANAGING THE SWITCH
The switch may be managed locally via a terminal connected to the COM
port, or remotely (SNMP or Telnet sessions) from a management station
connected to a switch port that is a member of the same VLAN as the
switch’s Host Data Port. (By default, this is the default VLAN.) When the
switch is configured with VLANs, special precautions must be taken to
use remote management.
3.1.1 Switch Without VLANs
When the switch is powered up, the switch uses its default settings to
switch frames like an 802.1D switch. In this default configuration, all
ports are a member of the default VLAN (VLAN 1) including the virtual
Host Data Port of the switch, so any port can be used to manage the
device as shown in
Figure 3-1 .

NOTE: All ports, including the virtual Host Data Port, are
members of the default VLAN. Therefore, any station
shown may be used as the management station.
