link aggregation 1

[boymarty24]

Hi,

I wonder if someone here has setup link aggregation on a 3750 with standard ios image ( 24 gb switch ). Does it even work on that model? Search on ciscos homepage but havent found anything useful so far.

I assume you mean EtherChannel?

interface range GigabitEthernet 1/0/1 - 4
channel-group 1 mode on
!


You need to ensure that the configuration of the physical interfaces all match before you apply the command so it is usually a good idea to 'default' them:

default interface range GigabitEthernet 1/0/1 - 4

Yes i mean etherchannel =)

Ok that sounds good. We have a admin for a serverX who want to boost the traffic. So i assume this is the way to go then.
In this case i need to run Lacp, any opinions about it?

I am not very experienced in this kind of configurations. I am more a pix/asa guy =)

I agree with ADB100 about the requirement to be the same both ends, but if you use Auto then you may have issues. I would manually set each end of the etherchannel links to 100 full or whatever you guys require.

Tried to find some more information about this but cant find any. Only examples is between switches. I would like to see one when you connect a catalyst to a server or something. Is it same same?

And one more question. Do i need to configure this on a new vlan or can i put straight on the existing one?

This is now up and running against 5 servers on different vlans. Working great. Had some problems getting lcap to work properly in the beginning.

ADB heres your star for pointing me to the right direction!
