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.
