Port Trunking
Port Status and Configuration
• All ports in a trunk must have the same media type and mode (such
as 10/100TX set to 100FDx, or 100FX set to 100FDx). The flow control
settings must also be the same for all ports in a given trunk. To verify
these settings, see “Viewing Port Status and Configuring Port Param-
eters” on page 10-2.
• You can configure the trunk group with one to eight ports. If multiple
VLANs are configured, all ports within a trunk will be assigned to the
same VLAN or set of VLANs. (With the 802.1Q VLAN capability built
into the switch, more than one VLAN can be assigned to a trunk. See
the chapter “Port-Based Virtual LANs (VLANs) and GVRP” in the
Advanced Traffic Management Guide.)
(To return a port to a non-trunk status, keep pressing the Space bar
until a blank appears in the highlighted Group value for that port.)

6. Move the cursor to the Type column for the selected port and use the
Space bar to select the trunk type:
–LACP
– Trunk (the default type if you do not specify a type)
All ports in the same trunk group on the same switch must have the same
Type (LACP or Trunk).
7. When you are finished assigning ports to the trunk group, press [Enter],
then
[S] (for Save) and return to the Main Menu. (It is not necessary to
reboot the switch.)
During the Save process, traffic on the ports configured for trunking will
be delayed for several seconds. If the Spanning Tree Protocol is enabled,
the delay may be up to 30 seconds.
