Last week i did an update to OnTap 8.1.4p3 7-Mode on one of our v-series devices (V3240) and after the reboot it it decided that one of the 2 physical network interfaces would change from a speed of 1Gbps to 100Mbs. This caused a mismatch because it was in an interface group and the interface group decided it was going to go offline.
Essentially the interface group (vif0) should contain e0a and e0b. At the moment it only has e0b in due to this mismatch. If you look at the ifconfig output you can see that e0a is reporting a speed of 100Mbs. The network guys are telling me the network switch ports are reporting a speed of 1Gbps, Full Duplex and look fine. I had them shut down the ports and that made no difference, i disabled/enabled the port on the NetApp and now running out of ideas.
I am working with our network team on this but wonder if anyone has come across this before and/or has any possible ideas for me to try as i am stuck at this moment. I have detailed the output of /etc/rc, /etc/hosts and an ifconfigoutput if that helps?
Output of /etc/rc

To be honest checking the cable was my next move. I was working on the basis that the link was up and working as expected and the cable has not been touched in the slightest. But i will be going to ask if a temporary cable can be put in just to test it for sure and see what happens. Wasn't sure if there could be some 'funky' netapp stuff going on here could look at as well .
