Thanks Adam,
It was always nice from the stand point of "explaining things to security" to have a "management port" Now that there is no more port like what many called "old 100M port", I understand that vlan is the good option. RLM and Console for sure are great but not for scripting via rsh/ssh. The other option is to manage over data IP and bother with VLAN, sure is not the most elegant way of doing it but very simple. I sure do miss the "old mgmt port" though. I would not mind having 5 gigE ports so I can work with even number of data ports for VIF creation.

There never was any requirement or designation of a "management" port in ONTAP.  Most filers pre-3000 series
had a single on-board 100Mb port that many decided would be a management port, but it possesed no special
privledges or function other than it was the port that the filer would obtain its first address via DHCP if the filer booted
and was not configured.  For filers with multiple on-board ports, that port is the "e0a" port (same as the FAS 250/270).
But that's really the only thing special about the on-board port.  If you CHOOSE to make one of the ports a management
port, you can, but you don't have to.  You could use vlan tagging as specified below so you don't chew up a port.  Or if
by "management" port you just want a separate port to login to the port, consider using the RLM port (if your filer has
one, I think you have to order a 3020 with one, but the 3050 and above have them standard) as the management port.
 
Just a thought.

Subject: Re: 3020 Cluster: which one is management interface

Blake,
Thanks! So which one is managment then?
I see dedicated managemnet iterface on all filers but 3020.
Or do you manage over the data IP?
Thanks

You can use vlan tagging on it that final multi mode trunk vlan.
There should be 3 slots available for expansion cards if you need a
dedicated interface for managment.  Depending on how much storage is
attached to this config, you should be able to use one of those slots
for a network card.
