layer 2 etherchannel - Cisco & HP

jeansamarani · ‎04-15-2009

Hi,

we have 2 switches HP and Cisco and we are trying to bundle the 2 physical links between them into one logical link.

attached the configuration on the cisco switch.

is there anything wrong from my side on the cisco switches ?

any idea what can be the issue that it's not allowing to form the bundle ?

thank you in advance.

Hoi Jean,

How did you configure the links on the HP switch. It could be caused by the native vlan command.

Hi Michel,

thanks for the quick feedback,

do you mean that there is no need for the native vlan command in this case because the HP switch doesn't behave like a hub.

Hi Jean,

So far I know there is no command on an interface on a HP switch.

Did you use the LACP command also on the HP switch.

I used these command on the cisco switch

interface Port-channel1

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 15,150

switchport mode trunk

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 15,150

switchport mode trunk

channel-protocol lacp

channel-group 1 mode active

And this command one on the HP2610

trunk 27-28 trk1 lacp.

Hope to help.

Regards,

Michel

Hi Michel,

basically we are using the same command,

we will try to remove the switchport trunk native vlan command from cisco.

let's see if it will help.

thanks
