I have done lots of etherchanneling in data centers. But I have never tried it as a failover topology between two sites. In the LAN it works great for the additional bandwidth and for failover. i.e. if one of the *ethernet in the bundle goes out the other members of the etherchannel just keep chugging along.
So imagine site A with Cat2948 2/49 ethernet over fiber to carrier 1 and 2/50 ethernet over fiber to carrier 2. Site B 25 miles away is setup the same. Ports 2/49 and 2/50 are configured as an etherchannel bundle. On the surface it seems like this should work. But might I be missing something perhaps with the two carriers, timing, the distance or other?
The hand off at each end is fiber to a switch that is provided by the carrier. That switch then connects into the carrier's fabric and terminates at the far side with another switch. The single circuit which is already in place behaves just like any LAN GigE over fiber connection in a data center. So I think adding a second similar circuit (via another carrier) will behave no differently.
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
