I would like to bond/team 2 ports on my 3750. This is what I current have:
interface Gigabitethernet4/0/21
description "Team Member 1"
Switchport mode access
no ip address
no mdix auto
channel-group 9 mode active
spanning-tree portfast
interface Gigabitethernet4/0/22
description "Team Member 2"
Switchport mode access
no ip address
no mdix auto
channel-group 9 mode active
spanning-tree portfast
Not working tho... any help appreciated. Thanks!

Hi
Send these outputs to dahuja@cisco.com
"show etherchannel summary"
"show tech-support
What make of NIC are you using on the server
Once I receive the output would be able to analyze the issue and come down to a resolution

It appears as though you're configuring Etherchannel.
Is the 2nd switch, connected to interfaces Gi4/0/21 and Gi4/0/22, configured the same?
3750 Etherchannel ref doc:

Actually - I have two gig network cards in my backup server that are teamed - and looking to get two ports on the same switch teamed. Just need more bandwidth for my backup agents to use.
Etherchannel does this correct?

int g4/0/21
switchport trunk encap dot1q
switchport trunk allowed vlan xx
switchport mode trunk
Channel-protocol lacp
channel-group 9 mode active
no spanning-tree portfast
int g4/0/22
switchport trunk encap dot1q
switchport trunk allowed vlan xx
switchport mode trunk
Channel-protocol lacp
channel-group 9 mode active
no spanning-tree portfast
Vlan xx is the vlan that your server is in.

Will give it a whirl. The main switch in on the same network as the server, so don't need a Vlan.
Curious about the addition of:
Switchport trunk encap dot1q
and turning off spanning-tree portfast
Are these recommend settings?

Those are trunk settings, for trunking vlans across switches/routers.
Not sure if the server NIC teaming process is going to work like you need.
I as understand teaming, 1 virtual IP address = 1 virtual MAc address, across 2 physical NIC connections.
AFAIK this is not a throughput enhancement. You may want to read up on the Server NIC teaming and see how they recommend setting it up.
Etherchannel is a L2 switch to L2 switch function.

Makes more sense to me. Ah. Yep this is just two network ports coming out out of my backup server going into 1 switch.
Doesn't sound like I can do it through etherchannel then. Thanks!

Added the config and could not ping the server. Changed switchport mode trunk back to switchport mode access and could ping but port still show as 1 gig.

Hi,
Do you have a Port Channel interface setup?
Take a look at the following link example.
02-14-2007 12:54 PM
No I don't have a port channel interface setup.
02-14-2007 01:21 PM
channel-group 9 mode active
this automatically creates a port channel group 9 for LACP
02-14-2007 02:33 PM
I did a little researching. There are several NIC teaming methods, redundancy, load balancing, throughput aggregation.
For the basic port channel to work with a non-PagP/LaCP host, you'll need to change:
channel-group 9 mode active
to
channel-group 9 mode on
on both ports.
Try that, and here's a few refs I stumbled upon.

no good - even tho mode on is an option in the list, it does not accept it. Do I need to create the channel first?
