It answers most of the questions that you're asking about etherchannel.
I'll leave the second question to someone else ;^)

Greetings.
Has anyone configured a quad 100 ethernet card with EtherChannel trunking? I searched the archives for this lists and didn't find any subject heading with "EtherChannel" or "trunk."
My proposed plan is (I hope it is this simple):
o create a virtual interface with `vif create` o replace the ifconfig line in the rc file: ifconfig e0 mediatype 100tx-fd `hostname`-e0 with ifconfig vif1 mediatype ??? `hostname`-vif0 o reboot the filer
There is probably a more elegant way to do this live and online, by downing e0 and then upping vif0, but I'll be doing this off hours anyway, so a reboot is not a problem.
I've got a brand new F740 running ONTAP 5.2.1, and I'm new to NetApp filers, so please be gentle with a newbie to this technology. What a nice machine, though. Had it running at:
CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 91% 1785 876 0 9346 1783 787 9056 0 0 8 91% 1858 722 0 9796 1100 182 10326 0 0 7 87% 2147 562 0 8924 1369 209 9138 0 0 8 83% 2007 934 0 7491 1330 147 8642 0 0 8 85% 2051 990 0 7703 1596 592 7265 0 0 8
for a while today; at this level, our previous file server (not a NetApp) would have long since fell over and died.
If I've already nearly got it pegged in this peak operation (sustained is about 30-50%...so far), and the theoretical limit of the 100 Mb/s fd link is ~12,200 kB/s in and out, do I really need this quad 100 card? Will spreading the network load reduce the CPU load?
