Port Trunking

Trunk Configuration Methods

Trunk Configuration Methods

Dynamic LACP Trunk: The switch automatically negotiates trunked links between LACP-configured ports on separate devices, and offers one dynamic trunk option: LACP. To configure the switch to initiate a dynamic LACP trunk with another device, use the interface command in the CLI to set the default LACP option to Active on the ports you want to use for the trunk. For example, the following command sets ports C1-C4 to LACP active:

ProCurve(config) int c1-c4 lacp active

Note that the preceding example works if the ports are not already operating in a trunk. To change the LACP option on ports already operating as a trunk, you must first remove them from the trunk. For example, if ports C1 - C4 were LACP-active and operating in a trunk with another device, you would do the following to change them to LACP-passive:

ProCurve(config)# no int c1-c4 lacpRemoves the ports from the trunk.ProCurve(config)# int c1-c4 lacp passiveConfigures LACP passive.

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.
