HP Virtual Connect for c-Class BladeSystem Version 3.00 Setup and Installation Guide for HP Integrity BL8x0c i2 Series Server Blades, Fifth Edition

Installation 62
By default, all ports on a Catalyst 4500/4000 switch and a Catalyst 6500/6000 switch use channel
protocol PAgP and as such are not running LACP. For all ports concerned, you must change the channel
mode to LACP.
On switches running CatOS, you can only change channel mode per module. In the following example,
channel mode for slots 1 and 2 are changed using the following command:
set channelprotocol lacp module_number
The changes can be verified by using the following command:
show channelprotocol.
CatOSSwitch (enable) set channelprotocol lacp 1
Mod 1 is set to LACP protocol.
CatOSSwitch (enable) set channelprotocol lacp 2
Mod 2 is set to LACP protocol.
CatOSSwitch (enable) show channelprotocol

On switches running Cisco IOS Software, specify which interfaces should be using LACP by entering the
following interface configuration command:
channel-protocol lacp:
CiscoIOSSwitch(config-if)#channel-protocol lacp
Example switch configuration of a Cat 6500 switch using IOS. Ports 7/46, 7/47, and 7/48 on the Cat
6500 switch are used to uplink to the Virtual Connect module:
