Does my router support Etherchannel

[salemmahara]

Hello everyone

As you know, one of the most popular approach to cover Load balancing and also Link Failure is Etherchannel. Again it's a good solution when your upper or downer layer device is a set ( Stack of switches or VSS or .... ).

Cisco routers are produced in different types . 3900 series , 3800 series , 4000 series ( ISR ) and 1001, 1002 and .... ( ASR ) and ........ !

Unfurtunately , it looks not all of them support L3 Etherchannel and I really don't know way. If a router doesn't support it, how it can be connected to Stack or VSS or .... ( redundant devices ).

Could you please help me to make it clear which " How to determine this before purchase? "

Cisco Feature Navigator is not a good tools to determine it . All searches  with keywords of "FEC , GEC , Etherchannel , Layer 3 Etherchannel and .... " with no adequte result.

Hi

You could check the data sheets for each model as another option or check the configuration guides for the platform on the website itself

just google platform model with data sheet , i can see the command is there in my 4331s and asr1001xs so they suport it

Or when your looking at the model on the website there is a live help you can use too and ask them to be sure if the documentation isnt accurate

Hello Mark

Thank you for replying and also thanks a million for testing the scenario on your devices.

As you mentioned, I searched "configuration guilde" section and again couldn't find clear description.

Any other solution please?

Often many routers do support, but perhaps without features like LACP or all the other Etherchannel options you might find on a switch, for example, choice of the load balancing algorithm.

Routers, being routers, also support multi-link routed links, so when working with another L3 device, L2 Etherchannel isn't then often needed.

Unfortunately, I don't know of an easy way to determine, from documentation, whether a router supports some variant of Etherchannel. Cisco whitepapers or tech notes, though, might mention it.
