Hi,
I was trying to configure a FAS2040 as per the best practices outlined in http://media.netapp.com/documents/tr-3749.pdf. It mentions the use of a VIF with all 4 available NICs using LACP, VLAN tagging, enabling jumo frames and setting flow control to Send.
All seemed fine until I set flowcontrol to Send, after which I completely lost communications with the filer. The switch was configured correctly and listed the interfaces as up but I couldn't connect to or ping any of the IPs.
Here's the jist of the config (names and IPs are different, just keeping it simple)
vif create lacp vif0a -b ip e0a e0b e0c e0d
vlan create vif0a 101 102 103
ifconfig vif0a-101 10.0.1.1 netmask 255.255.255.0
ifconfig vif0a-102 10.0.2.1 netmask 255.255.255.0
ifconfig vif0a-103 10.0.3.1 netmask 255.255.255.0
ifconfig vif0a-102 mtusize 9000
ifconfig e0a flowcontrol send
ifconfig e0b flowcontrol send
ifconfig e0c flowcontrol send
ifconfig e0d flowcontrol send
reboot
After the restart, the filer was completely unreachable. When I removed the flowcontrol send from each interface connectivity was restored.
Am I trying to do something that is not supported or are the problems likely to be elsewhere?
Thanks
