Hello,

Thank you for your question. In regards to the Enterprise License, it really depends on what you want to accomplish with your configuration now and what your longer term plans are. Below are the various features that the Enterprise license provides. It depends on what features you need to use and how you plan to configure the switches as to what licenses you may need. I would recommend contacting your EMC Sales Consultant to see what you may or may not need for your exact configuration. There may be a way to configure your switches to optomize their use and minimize the licenses you require.

Thank you.

License 1 switch in each fabric and you should be good. However, if that switch fails, you loose that feature on that fabric

I know it's a veeeeery late reply, but I was thinking.... do I need a license to use portchannels on 91xx's ?

Hello,

Only the above stated features require the license.

Thank you.

I was only making sure that I understood. On Brocade you do need a license for trunking, so I asked myself why I didn't need this on cisco....

Thanks !
