How do I configure multiple ports from a 2524 to a server

[BobW333]

As we need more bandwith between the network and servers, I've been asked if it's possible to have multiple fastethernet ports connected between a 2524 and Compaq servers to increase the available bandwidth and share the load.
I'm not sure how to do this from the switch so any help would be appreciated. (Our server guys say they will need to "team" the ports on the server)

You could do that using port etherchannel. I am sending you a generic configuration example where we are connecting two switches. You should replace one of the switches by your server.
Be aware that the server NIC must also support etherchannel.
I suppose you have a 2924XL switch.

Thanks for this.

Had a prob finding the page you gave me as I don't have partner access but got there in the end.

Switch is WS-C2924M-XL-EN with c2900XL-h2s-mz-120.5.1-XP.bin software running.

Do you have any experience of setting up the Compaq's at all?

I'll let you know how I get on.

Sorry for using a privileged user.

I do not have any experience with setting up etherchannel for hosts. You you could provide some feedback I would appreciate.

Best regards,

I though a 2524 was a Router!! Anyway I assume you mean a 2924.

Etherchannel on a 2924 is "port Group"
Example this will create a 2 port group.
fastethernet 0/1
speed 100
duplex full
port group 1
switchport access vlan 2
fastethernet 0/2
speed 100
duplex full
port group 1
switchport access vlan 2

You must use either port 1&2 or 1,2,3 & 4 for a group.
You cannot group ports 2&3 or 2&5 etc

For the compaq host , modern servers genrally have 2 x ethernet ports. Create a team and configure with "switch assisted load balancing" I balance based on mac-address and all works ok.

Cheers

mark,

Thanks for this, just a quick question;

What function does the "switchport access vlan 2" statement do?

switchport access vlan2 makes the interface your configuring a member of vlan 2

Umm, why do you want to put them in a seperate vlan, if you do that, then you'll need a layer 3 device to get between vlans.. So you don't want that "switchport access vlan 2" command in there..

"You cannot group ports 2&3 or 2&5 etc"

Where did you get this info at? I've never had a problem using anyport that I want to for etherchannel. Nor have I even read anything that says this is not possible. Hell even on larger switches you can do it across blades now.
