Joe Wilson If you’ve ever run out of bandwidth on an up link you know you maybe thinking you need to setup an EtherChannel or PortChannel. But have you ever done it or are you wondering how to setup an etherchannel?
This video does a great job of showing you how setup an etherchannel connection within your environment

I have a 3560 and 2960 and the ip address command is not there. Did cisco change that?
Did enable ip routing? You can do this by typing:
switch(config)#ip routing
I hope this helps
Ip address is not here either. Ip routing did not help. Hmm??
To create L3 etherchannel, you need a L3 switch.
I need the configuration of building of an Ether channel…
Pradeep,
Thanks for your comment. Setting up an etherchannel is fairly straight forward. Connecting between two Cisco switches you first create a port channel interface. Here is the config for that:
<code>
Switch-A>#(config) interface Port-channel1
Switch-A>#(config) description Connected to Switch-B
Switch-A>#(config) ip address 10.1.1.1 255.255.255.254
Switch-A>#(config) no ip redirects
Switch-A>#(config) no ip unreachables
Switch-A>#(config) no ip proxy-arp
Switch-A>#(config) logging event link-status
Switch-A>#(config) logging event bundle-status
!
Switch-B>#(config) interface Port-channel1
Switch-B>#(config) description Connected to Switch-A
Switch-B>#(config) ip address 10.1.1.2 255.255.255.254
Switch-B>#(config) no ip redirects
Switch-B>#(config) no ip unreachables
Switch-B>#(config) no ip proxy-arp
Switch-B>#(config) logging event link-status
Switch-B>#(config) logging event bundle-status
</code>
Next add your interfaces to the port-channel. This would be done on both switches.
<code>
interface GigabitEthernet5/4
description EtherChannel
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
channel-group 1 mode desirable
!
interface GigabitEthernet5/5
description EtherChannel
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
channel-group 1 mode desirable
</code>
In the example above we've put tow gigabit interfaces into one port-channel (EtherChannel)
And thats about it… let me know if you still have questions and thanks again!
