Static trunk

The switch uses the links you configure with the Port/Trunk Settings screen in the menu interface or the trunk command in the CLI to create a static port trunk. The switch offers two types of static trunks: LACP and Trunk.

Trunking Options

LACP (802.3ad)

Provides dynamic and static LACP trunking options.
  • Dynamic LACP — Use the switch-negotiated dynamic LACP trunk when:

    • The port on the other end of the trunk link is configured for Active or Passive LACP.

    • You want fault-tolerance for high-availability applications. If you use an eight-link trunk, you can also configure one or more additional links to operate as standby links that will activate only if another active link goes down.

  • Static LACP — Use the manually configured static LACP trunk when:

    • The port on the other end of the trunk link is configured for a static LACP trunk.

    • You want to configure non-default spanning tree or IGMP parameters on an LACP trunk group.

    • You want an LACP trunk group to operate in a VLAN other than the default VLAN and GVRP is disabled.

    • You want to use a monitor port on the switch to monitor an LACP trunk.

Trunk(non-protocol)

Provides manually configured, static-only trunking to:

  • Most Switch and routing switches not running the 802.3ad LACP protocol.

  • Windows NT and UX workstations and servers

Use the Trunk option when:

  • The device to which you want to create a trunk link is using a non-802.3ad trunking protocol.

  • You are unsure which type of trunk to use, or the device to which you want to create a trunk link is using an unknown trunking protocol.

  • You want to use a monitor port on the switch to monitor traffic on a trunk.
