Hi
On Thursday 10/18/2012, the network group will make a change turning off pr=
oxy-arp on the W91 data center subnets. During an initial run, it was found=
that if the proper subnet mask is not configured, the device would fall of=
f the network. We had identified and worked with the customers that were af=
fected and received confirmation that the network settings on these devices=
were corrected. However I am sending the notification to ensure that all c=
ustomers please double-check the network settings on any hosts using the MI=
TNet.
Please let me know if there are any questions.
Thanks
