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, refer to 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 on all three Dell Force10 platforms — C-Series,

E-Series, and S-Series — as indicated by the following symbols under command headings:

c e s

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.

clear lacp counters

c e s

Clear Port Channel counters.

Syntax

clear lacp port-channel-number counters

Parameters

Defaults

Without a Port Channel specified, the command clears all Port Channel counters.

port-channel-number

Enter a port-channel number:

C-Series and S-Series Range: 1-128

E-Series Range: 1 to 255 for TeraScale and 1 to 512 for ExaScale.
