Chris,

We use a 3750 in the UK for POC and evaluations - our config for
Etherchannel uses different commands -

interface Port-channel1
!
interface Port-channel2
!
interface GigabitEthernet1/0/1
 description Onstor-A fp1.0
 channel-group 1 mode on
!
interface GigabitEthernet1/0/2
 description Onstor-A fp1.1
 channel-group 1 mode on
!
interface GigabitEthernet1/0/3
 description OnStor-A fp1.2
 channel-group 1 mode on
!
interface GigabitEthernet1/0/4
 description OnStor-A fp1.3
 channel-group 1 mode on
!
interface GigabitEthernet1/0/5
 description OnStor-B fp1.0
 channel-group 2 mode on
!
interface GigabitEthernet1/0/6
 description OnStor-B fp1.2
 channel-group 2 mode on
!

This is a very basic configuration that provides 2 etherchannels - a 4
port and a 2 port, with no Vlans defined.=20

Hello all,
Onsite with Cisco. Can someone verify this is a good config for us with
etherchannel?

Thanks,
Chris

Chris,

Here are the commands I used to configure the etherchannel for the
Onstor eval units.
They are setup with lacp and pagp off (static).  Please let me know if
the config looks good.

Thanks,
Joe
