SSH to a Catalyst 6506?

Is it possible to do SSH to a Catalyst 6506 switch with dual supervisor modules with Routing on them? The current software rev on the ios side is

12.1(3r)E2, I know the required rev is at least

12.1(1)T, but it doesnt say the sup modules are supported. Any idea if its supported?

The focus of this board is AAA (Authentication, Authorization & Accounting) however, there are a number of professionals online who may be able to assist you.

If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center ( or speak with a TAC engineer. You can open a TAC case online at

If anyone in the forum has some advice for Reil, please reply to this thread.

Thank you for posting.

You need a 3DES license and Cat crypto software to have ssh functionality. You could also implement, or buy, a console server with SSH feature set which would give you added security and availabilty to access your systems.

Yes, I have just set it up not too long ago. Call the TAC and they can tell you the link to fill out the 3DES form and then from there you can download the 3DES IOS.
