Re: Trunk grouping vs. LACP?

This document will show the basic configuration needed to set up an 802.3ad link aggregate between a Catalyst 6500/6000 (running Catalyst OS [CatOS] system software) and a Catalyst 4500/4000 switch. 802.3ad is a new specification from the IEEE that allows us to bundle several physical ports together to form one logical port. This is very similar to the already existing Cisco EtherChannel Solution. The main difference is that the Cisco implementation uses a proprietary protocol called Port Aggregation Protocol (PAgP). The IEEE later defined within 802.3ad a new control protocol for link aggregation called Link Aggregate Control Protocol (LACP).

The primary advantage of using LACP (802.3ad) is for interoperability with other vendor switches. Since PAgP is Cisco proprietary, one cannot aggregate channels between a Cisco switch and a switch from another vendor unless LACP is utilized.
