All,
I appreciate any assistance on this. I just setup LACP on ports 3-4 and it is not working. Once I place the ports on vlan 1 the ports go inactive. If I place the ports on vlan 10 for instance they go live and are green. If they are on vlan 10 I can not see the server or anything. Any ideas? What information do you need other than what is below.
Here is info with them on VLAN 1
interface GigabitEthernet0/3
description Zeus LACP
channel-group 5 mode active
interface GigabitEthernet0/4
description Zeus LACP
channel-group 5 mode active
Solved! Go to Solution.

Thanks for your reply. Sorry, my mistake I wanted to ask for 'sh run int po5' instead of 'sh int'. By the way, based on your logs, it looks like the problem is that the channel members and port-channel interface configuration are not consistent. In order for the port-channel to work properly, the members need to have the same configuration, as well as the port-channel interface.
I would suggest to try the following, as you're using vlan 1 only:
conf t
int ra gi0/3 - 4
switchport mode access
switchport access vlan 1
int po5
switchport mode access
switchport access vlan 1

Yes, you need to configure the same settings (like same vlan) for both member ports, gi0/3 and gi0/4 if you are using those. That's why I was using 'int ra' in my example, which means 'interface range' so that you can configure multiple ports at the same time.

Hi,
It would be good to know the following:
- What device is connected on the other side?
- How is the other side configured?
- Is the other side configured as a trunk port or access port?
- Configuration of interface Port-channel5 (sh int po5).
- Output of 'sh etherchannel 5 summary' when it's working and when it's not working.
- Do you see any error messages in the logs (sh log) ? If yes, paste some here.

You are the man!! Thanks!
I will need to do the same for port 1 and port 2 is that ok?

Cisco 2960 -> PORT-CHANNEL -> Apple Xserver? is this right?

What do you mean by this:
Cisco 2960 -> PORT-CHANNEL -> Apple Xserver
11-04-2010 12:43 PM
The layout is as follows:
Xserve -> 2 ports are link aggregated, or bonded in OS -> Cisco
