Port Trunking

Trunk Configuration Methods

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.

Protocol Trunking Options

LACP Provides dynamic and static LACP trunking options.

(802.3ad)

• 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.

(Refer to “VLANs and Dynamic LACP” on page 13-23.)

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

For more information, refer to “Trunk Group Operation Using LACP” on page 13-18.

Trunk

Provides manually configured, static-only trunking to:

(non-

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

protocol)

• Windows NT and HP-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.

Refer to “Trunk Group Operation Using the “Trunk” Option” on page 13-24.
