Optimizing Traffic Flow with Port Controls, Port Trunking, and Port-Based Priority

Port Trunking

• 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 9-2.

• You can configure the trunk group with one, two, three, or four ports

per trunk. 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 “Port-Based Virtual LANs (Static VLANs)” on

page 11-3.)

(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)

– FEC (Fast EtherChannel

trunk)

All ports in the same trunk group on the same switch must have the same

Type (LACP, Trunk, or FEC).

7. When you are finished assigning ports to the trunk group, press , then

(for S

ave) and return to the Main Menu. (It is not necessary to reboot

the switch.)
