EtherChannel from Intel Team to cisco swtch
I am trying to create an etherchannel (LACP) on the Cisco 3560G. The entire switch is currently VLAN 1. My question is:
When I create the etherchannel does it have to ve on a different VLAN or can it be on the flat VLAN 1? When I try to create an ether chaqnnel on VLAN one I get PO1 (SD) - Down instaed of up when I run CLI - #show etherchannel 1 summary.
When I run show spanning-tree interface port-channel 1 I don't see any spanning trees?

When I run show spanning-tree interface port-channel 1 I don't see any spanning trees?

I am trying to create an etherchannel from the switch to two nic ports on a server
Config looks okay to me. What does a "show ether summ" say?
ASKER
How does traffic get from VLan 1 to the new VLan 10? All lights are green and everything looks good but I can't ping and device on VLAN1 from the server on VLAN 10. This is all from the same switch.

Does the EtherChannel have to be on a different VLAN than the rest of the switch? Because I can't communicate across VLans?
Your etherchannel link is working.
Traffic between VLANs would have to be routed by either the 3560 or some other routing device.
Traffic between VLANs would have to be routed by either the 3560 or some other routing device.
ASKER
DO you have any idea how that type of routing is done
You would need a vlan1 interface and a vlan 10 interface defined on the 3560 with the appropriate IP addresses. Then the hosts would need to have default gateways on the vlan interfaces.
ip routing
int vlan 1
ip address 192.168.1.1 255.255.255.0
no shut
int vlan 10
ip address 192.168.2.1 255.255.255.0
no shut
Give this link a look for how to configure a 3560 for layer 3 routing.

ASKER
So, Does an ether channel need to be on it's own VLAN, or can it be on the default VLan 1? This way routing will not be an issue?
It can be either. Depends on what you're trying to accomplish. In your case, if you want the server on the same broadcast domain as the hosts that are connecting to it, put the server in the same VLAN as the hosts.
ASKER
When I setup the etherchannel on VLAN1, the two ports are amber and I have no connection to anything on the switch or the network. When I set it up on VLAN10 The ports are green but I don't have access to anything on the switch or network due to the layer3 routing.
How are you putting the etherchannel in VLAN1? What commands are you using?
ASKER
Gi0/1

For Each Port I do:
Switch#conf t
Switch(config)#int Gi0/1
Switch(config-if)#switchpo rt
Switch(config-if)#Configur e the port as an access port and assign the appropriate VLAN.
Switch(config-if)#switchpo rt mode access
Switch(config-if)#switchpo rt access vlan 1
Switch(config-if)#spanning -tree portfast
Switch(config-if)#channel- group 1 mode active
Then I do this once:
Switch(config)#port-channe l load-balance src-mac

What I wanted was, "what commands do you use to set the vlan for the etherchannel?"
That said, the commands to change the vlan membership of an EXISTING etherchannel to vlan 1 would be:
conf t
int po 1
switchport access vlan 1

Interesting.
Try:
int range po1 , g0/1 - 2
switchport access vlan 1
and do you get any messages when you enter the commands?

I will as soon as I get it back the way it was. I wanted to start over so I ran:
conf t
interface range gigabitethernet0/1 -2
no channel-group
I am trying to get the two ports back to regular switch ports on Vlan 1 and remove the channel group / port-channel1. The two ports show up as VLan 1 but how do I delete the port-channel and start fresh.

You can't enter a "no" command? Where is the "^" pointing?

It is pointing at the 1,
It almost looks like it may have been deleted but still shows up in the show config. NOt sure what is going on.

Everything went ok but when I tried to delete with no int po1 I get the same error pointing at the 1
ASKER
OK, I just went into the Web Interface for the switch and noticed the two ports were not active. I activated them via the web interface then went back into telnet and ran show config again and everything looks back to were it was. I will try to start again after lunch.
Thank you so much for your help so far. Hopfully this new etherchannel on VLAN 1 will do the trick. I'll let you know.

That worked! It must have been stuck the whole time. One last question before I close this. How can I verify that the throuput of this etherchannel is better than the throuput if I just had one nic to a regular port on the switch?

Can you post the config of the cisco switch?
