We've used mode=1 (active-passive) bonding under DRBD for years across 
numerous installs and countless test and prod failures without issue. We 
still run through switches (link1 to switch 1, link2 to switch 2, 
hitless failover config on the stack). We can and have failed NICs, 
cables and switches without interruption.

We've documented this setup here;
