Re: Strange network situation

If you want both links up at once to double your throughput, or for failover (to avoid a SPOF in the NIC), you want what's called "trunking" or "bonding". It's slightly tedious and flaky; mostly I wouldn't bother.
I did this in the past... I just used Google to search for "Linux bonding" to see that not much has changed it seems(?). You find "generic" Linux commands and configuration examples for Red Hat/CentOS and Ubuntu etc. I use it under FreeBSD just now, it's called a "lagg" interface there (link aggregation and link failover interface) but the result is the same. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-aggregatio... The only "flakiness" I experienced had to do with confused switches. The Ciscos I have at the moment are okay. The handbook above touches the Cisco part too, as well as "how it works" (also useful for penguins). Regards Peter

IIRC (it was a while ago) it worked fine in our lab, but once we started actually shoving >1Gbps down a bonded 4×1gbps NIC, we got weirdness. (Like, one quarter of the frames would just disappear.) So we just said "fuck it" and bought 10gbps NICs thereafter, because that was cheaper than trying to finesse it.
