36 CHAPTER 4: CONFIGURING THE SWITCH
Figure 19 Uplink VLAN Configuration
To set up the configuration shown in Figure19, do
the following:
1Create VLAN2 on both Switch 1 and Switch 2, and
assign the same name to it. You need not create
VLAN1 since it exists by default.
2On Switch 1, set the ports that you want to be part of
VLAN2 to Desktop mode. Set one port (for example,
port 16) to Uplink mode.
Click Apply.
3On Switch 2, set the ports that you want to be part of
VLAN2 to Desktop mode. Set one port (for example,
port 8) to Uplink mode.
Click Apply.
4Connect the uplink port on Switch 1 (in this example,
port 16) to the uplink port on Switch 2 (in this exam-
ple, port 8).
Those ports on Switch 1 that are members of VLAN2
can now communicate with those ports on Switch 2
that are members of VLAN2.
Configuring Trunking
Trunking, also called “link aggregation”, refers to
bonding multiple ports into a single group to effec-
tively combine the bandwidth into a single connec-
tion or a “trunk”. If you are connecting the Switch to
another switch or to an Internet backbone, you can
aggregate links on the Switch to increase throughput
and prevent packet loopback between switches.
For link aggregation to work, the trunks must be con-
figured on both ends (switches).
The Switch does not support the Link Aggregation
Control Protocol (LACP), which is specified in IEEE
802.3ad.

Guidelines for Creating Trunks

■Any port on the Switch can be used for creating a
trunk.
■This switch supports a maximum of four trunks.
■Each trunk may contain up to eight members.
■A port may only be a member of one trunk at any
one time.
