Port Trunking

Trunk Group Operation Using LACP

Spanning Tree and IGMP. If Spanning Tree and/or IGMP is enabled in the

switch, a dynamic LACP trunk operates only with the default settings for these

features and does not appear in the port listings for these features.

Half-Duplex and/or Different Port Speeds Not Allowed in LACP

Trunks. The ports on both sides of an LACP trunk must be configured for

the same speed and for full-duplex (FDx). The 802.3ad LACP standard speci-

fies a full-duplex (FDx) requirement for LACP trunking. (10-gigabit ports

operate only at FDx.)

A port configured as LACP passive and not assigned to a port trunk can be

configured to half-duplex (HDx). However, in any of the following cases, a

port cannot be reconfigured to an HDx setting:

■ If the port is a 10-gigabit port.

■ If a port is set to LACP Active, you cannot configure it to HDx.

■ If a port is already a member of a static or dynamic LACP trunk, you cannot

configure it to HDx.

■ If a port is already set to HDx, the switch does not allow you to configure

it for a static or dynamic LACP trunk.

Dynamic/Static LACP Interoperation: A port configured for dynamic

LACP can properly interoperate with a port configured for static (TrkX) LACP,

but any ports configured as standby LACP links will be ignored.
