Link Aggregation Control Protocol

(LACP)

Overview

This chapter contains commands for Dell Force10’s implementation of Link Aggregation

Control Protocol (LACP) for the creation of dynamic link aggregation groups (LAGs —

called port-channels in FTOS parlance). For static LAG commands, the section Port Channel

Commands in the Interfaces chapter), based on the standards specified in the IEEE 802.3

Carrier sense multiple access with collision detection (CSMA/CD) access method and

physical layer specifications.

Commands in this chapter generally are supported by FTOS on all Dell Force10 systems as

indicated by the characters that appear below each command heading:

e E-Series, c

C-Series,

s S-Series, or .

Commands

Use the following commands for LACP:

• clear lacp counters

• debug lacp

• lacp long-timeout

• lacp port-priority

• lacp system-priority

• port-channel mode

• port-channel-protocol lacp

• show lacp

In addition, an FTOS option provides hitless dynamic LACP states (no noticeable impact to

dynamic LACP states after an RPM failover) on E-Series. Refer to redundancy protocol in the

High Availability chapter.
