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 lacp
Removes the ports from the trunk.
ProCurve(config)# int c1-c4 lacp passive
Configures 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.
