Hello,
We need to increase the network badnwidth to our 740. It has the
bulitin ethernet port plus a quad card. The switch it's connected to is
a catalyst 5500. My understanding is the vif on the Netapp is compatible
with Etherchannel on the catalysts. We did the vif create on the Netapp
(DOT 5.3.4r3) and combined all 4 quad card ports into one interface, it
has an IP address, ifconfig shows them all as part of a virtual
interface. But what do I need to do on the Cisco side? When testing
this on a 520 in the past, we tried enabling etherchannel AND trunking
on the ports, to no avail -- all data appears to be going through the
4th interface. vif stats <vifname> shows about 3 or 4 packets per
second on e3a through e3c, and thousands through e3d. I figured that
maybe it just counts the entire vif's packets on the e3d interface; is
that correct? Even so, though, with heavy speed testing from multiples
clients, all the data continued to go through the last port, and never
broke 12 megabytes a second. I really suspect this is because we don't
have the Catalyst set up properly. Can someone out there who's done
this before tell me what we need to do on the cat?
Do I need to put the vif commands into the rc file?
Thanks in advance,
Justin Acklin
Oh, another thing is that almost every time we plug or unplug an
ethernet port on the netapp, or even sometimes doing an ifconfig, the
thing core dumps. Very annoying, apparently there is an open bug on
that, which is not fixed yet according the netapp engineer I opened a
case with the last time this happened.
