I am trying to setup a 2 by 1gbit link aggregate connection between a c6509 running ios and an HP Proliant DL server running Win2003. The HP server has Hp SLB teaming configured with 2 1gbit NIC cards.
My questions are:
1. what is the recommended protocol, LACP or PAgP ?
2. should I set LACP mode to ACTIVE (or use PAgP ON mode if PAgP is the preferred protocol) ?
Thanks for your support.

Hi
You should use lacp and use active mode.
Make sure from server side it is lacp (802.3ad).
Hope this helps

Hi,
I tried to convert an existing PAgP aggregate link to LACP but having problems bringing up the bundle. I did the following:
1. Config T
2. int range gi3/46 - 47
3. no channel-group 99
4. exit
5. no int po99
6. int rang gi3/46 - 47
7. channel-group 99 mode active
8. channel-protocol lacp
9. no shutdown
10. exit
11.int po99
12. switchport
13. switchport mode access
14. no ip address
15. swi acc vlan 10
16. sp auto
17. band 2000000
18 no shut
13. end
The Portchannel 99 was re-created but it's status is down/down. Also, I noticed the description field of the new Po99 is the same as the old po99 instead of being blank - meaning that it copied it from the old configuration.
What is the recommended way to reconfigure the Portchannel if I want to use the same portchannel number ?
.
And strangely, the HP server that the ports are connected to, with SLB teaming configured ports, show the teamed port up ? Doen't this mean that LACP is not actually established ?
Thanks for your response.

Hi
Follow following steps
1 - Make default interface configuration
with default int configuration on config prompt.
2. Remove int port-channel 99
3. Reconfigure interfaces with channel-group 99 commands( port-channel will automatically gets created)
Add channel-group 99 command last after switch-port mode access and other commands.
4. Dont do any configuration under port-channel interface
5. All interface configuration commands will appear automatically under port-channel interface
6. If any ports are going into err-disabled state....just do shut and no shut that interfaces
