Configuring link aggregation between a Cisco and ProCurve switch

This scenario configures link aggregation between a Cisco Catalyst 3560-8 switch (IOS version 12.2.53) and an HP ProCurve 2610-48 switch (firmware version R.11.22) using the LACP protocol.

Cisco refers to an aggregated link as a “channel-group” whereas HP refers to it as a “Trunk”. To confuse things even more Cisco refers to an 802.1q tag port as “Trunk” where as HP refers to it as “Tagged”.

Cisco switch configuration

Configure the trunk on interfaces fa 0/1 and 0/2, configure as Trunk and create a Channel Group.

Create VLAN 600/601 and define IP addresses

ProCurve switch configuration

Create a trunk interface, define interfaces in the trunk and define LACP as the link aggregation protocol.

Create VLAN 600/601 and define IP addresses

Testing/Troubleshooting

Testing the successful configuration can be performed by pinging one of the switches from the other switch.

On a cisco switch to check the channel group status use the command “show interface etherchannel“. This will identify port state, mode and protocol status which would be useful if troubleshooting issues.

On ProCurve switch use a combination of the commands “show trunks” and “show lacp” to provide more information on the lacp configuration.

Summary

As you can see there are very few commands to setup basic aggregated link between a Cisco and a ProCurve switch.
