When you ping to check MTU you have to use the right packet size and set the do not fragment flag. For example: ping -s 8972 -d 192.168.42.91
Without -d, it will work, except the packets are being broken up to get there.
Not sure if that's really what you're trying to do, but it is probably the most common mistake in setting up and testing jumbo frames configs.
Share and enjoy!

Thanks. It was an MTU mismatch. Ping was working which is what threw me off.

Check for mismatches in MTU with your data LIFs. (are they using 9000 MTU?)
Also, is the user being used to add the CIFS server account a member of the domain you're adding the account to?

Has anyone seen the error listed below while setting up CIFS in cDOT? The filer is running 8.2P3. This has been a very straightforward process in the past for me, but with the newness of cDOT, I'm not finding a lot of information when I search. Thanks!

In order to create an Active Directory machine account for the CIFS server, you must supply the name and password of a Windows account with sufficient privileges to add computers to the "CN=Computers" container within the " XXXXXX.local" domain.
Enter the user name: XXXXXX
Enter the password:
