Trunking ProCurve 2800 to Cisco 3750

Danny McLean — Thu, 02 Jul 2009 14:45:22 GMT

I need to know the most efficient way to trunk 3 1GB fiber links between these switches. Both HP and Cisco have the native vlan of 1. Each HP switch will be in its own VLAN, and the Cisco port will be assigned to the same VLAN.

I simply need a bigger pipe.

Thanks

You could try LACP, but a staticly
defined trunk is probably easiest.

Example to use static trunking between
ports 1-3 on a Cisco to a Procurve...

interface GigabitEthernet1/1
channel-group 1

interface GigabitEthernet1/2
channel-group 1

interface GigabitEthernet1/3
channel-group 1

and on the Procurve

interface 1 no lacp
interface 2 no lacp
interface 3 no lacp
trunk 1-3 Trk1 Trunk

So far so good. I tested this on a single 2848 using two ports and two different ports in a 3750 stack and both ports came on. So i am assuming all is well here.

Thanks for the help

So is working but not working. I got all of them setup but I am getting intermittent time outs, while pinging i lost about 25 out of 400-500 packets. This is significant.

Any ideas?
