I was wondering what options there are for enterasys b-series port security: 1 - I want to use port security to limit 1 mac address per port (like the "sticky" command in Cisco) to avoid users bringing in personal switches 2- I'm also (separately) ...

I want to put a 3705i AP in a remote office but the switch is an Enterasys A series and does not have PoE - does anyone know of a compatible PoE injector? Or a few to choose from?

I'm looking for the command to set the speed and duplex on an Enterasys port (100mbps full and 1gbps full) does anyone know the syntax and/or able to give me an example or point me to a good resource? Thanks in advance

How to set the admin status of a port from the CLI - I can set them from the Web interface easily enough but I wanted to know the corresponding command to edit the "Admin Status" field in the show port status command
