Ether-channel on Cisco router.

I know it is possible to configure Etherchannel on a Cisco switch. A customer is asking if this can be done on a Cisco router (combining 2 ethernet interfaces into 1) for redundancy in case 1 interface go down. Can anyone confirm whether this can be done? Thanks.

Re: Ether-channel on Cisco router.

Are there any other good ways of attaching a router to a switch (or pair of switches) in a fault tolerant manner?

Re: Ether-channel on Cisco router.

IMO, yes, otherwise, it is too costly to use router port for only increase the bandwidth but the WAN side is low bandwidth only. Normally, I could suggest to use L3 switch instead of router to enable Etherchannel.

Hope this helps.

Re: Ether-channel on Cisco router.

I found the following FAQ on the Cisco 2800 page:

Q. Do the LAN interfaces on the platforms support aggregation through EtherChannel or PAGP technologies?

A. No, the onboard LAN interfaces do not support aggregation technologies. Aggregation can be achieved using one of the EtherSwitch network modules, or the EtherSwitch Service Module. No modules support aggregation in the Cisco 2801.

This means it is possible on a router with a Etherswitch module (a switch basically).

The 1800 fixed series router has 8 LAN port built-in. Does any one know if these Lanport can be configured for Ether-channel?

No Support for Etherchannel.

Re: Ether-channel on Cisco router.

Hi,

You can do it only if its ESW not the FE Routed Interfaces on the Router.

Moreover, you can suggest the customer to look into the options of HSRP as otherwise even if the Interfaces are made fault-tolerent, the Router becomes the Single-Point of Failure.
