Port Trunking

Port Status and Configuration

LACP Note LACP operation requires full-duplex (FDx) links. For most installations,

ProCurve recommends that you leave the port Mode settings at Auto (the

default). LACP also operates with Auto-10, Auto-100, and Auto-1000 (if negotia-

tion selects FDx); 10FDx, 100FDx, and 1000FDx settings.

Fault Tolerance: If a link in a port trunk fails, the switch redistributes

traffic originally destined for that link to the remaining links in the trunk. The

trunk remains operable as long as there is at least one link in operation. If a

link is restored, that link is automatically included in the traffic distribution

again. The LACP option also offers a standby link capability, which enables

you to keep links in reserve for service if one or more of the original active

links fails. See “Trunk Group Operation Using LACP” on page 12-15.)

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 ethernet 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 configures ports C1-C4 to LACP active:

ProCurve(config) int c1-c4 lacp active

Note that the above 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 disable the trunked ports that you want to reconfigure. 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:

1. Go to the port context for ports c1 - c4 and disable these ports.

ProCurve(config)# interface c1-c4

ProCurve(eth-c1-c4)#_

ProCurve(eth-c1-c4)# disable

2. Change all four ports to LACP-passive and re-enable the ports.

ProCurve(eth-c1-c4)# lacp passive

ProCurve(eth-c1-c4)# enable

Note If you change the port trunk configuration on a link, ensure that the port trunk

configuration on the other end of the link matches the new configuration.

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 LACP and Trunk static trunks.
