HP Virtual Connect 1.10Gb-F Ethernet Module for c-Class BladeSystem - Manual (Page 49)

Installation 49
In the example below LACP is used on the Cisco Switch to connect to a shared uplink set using three
uplink ports. VLANs 10, 20, 30, and 40 from the network are tagged on the three shared uplink ports.
NOTE: Change Channel Mode to LACP on the Cisco switch.
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

6500 switch are used to uplink to the Virtual Connect module):
