How to Setup EtherChannel

14 Feb

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

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:

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

Next add your interfaces to the port-channel. This would be done on both switches.

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

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!
