Viewing and configuring a static trunk group (Menu)


To avoid a broadcast storm, configure port trunking before you connect the trunked links to another switch, routing switch, or server.(If you need to connect the ports before configuring them for trunking, you can temporarily disable the ports until the trunk is configured. See "Enabling or Disabling Ports and Configuring Port_Mode".)

This procedure uses the Port/Trunk Settings screen to configure a static port trunk group on the switch.

  1. Review the Prerequisites.
  2. From the Main Menu, select Switch Configuration ... , and then select Port/Trunk Settings.
  3. On the keyboard, press [E] (for Edit), and then use the arrow keys to access the port trunk parameters.

  4. In the Group column, move the cursor to the port you want to configure.
  5. Use the Space bar to choose a trunk group assignment (Trk1, Trk2, and so on) for the selected port.
    1. For proper trunk operation, 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.
    2. You can configure the trunk group with up to eight 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 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:
    1. LACP
    2. 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 is delayed for several seconds. If the Spanning Tree Protocol is enabled, the delay may be up to 30 seconds.

  8. Connect the trunked ports on the switch to the corresponding ports on the opposite device. If you previously disabled any of the trunked ports on the switch, enable them now. (See "Viewing Port Status and Configuring Port Parameters")

Check the Event Log to verify that the trunked ports are operating properly.
