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) ?
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
5. no int po99
6. int rang gi3/46 - 47
7. channel-group 99 mode active
8. channel-protocol lacp
9. no shutdown
13. switchport mode access
14. no ip address
15. swi acc vlan 10
16. sp auto
17. band 2000000
18 no shut
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 ?
