I'm having some trouble configuring my IBM BladeCenter S network modules. The modules are Cisco Catalyst 3012 switches (16 internal ports and 4 external port). I'm having trouble enabling the 4 external ports so I can connect them to my core switch (Cisco Catalyst 4948E-F). I have tried doing the no shutdown command (under the command line and console) but it gives me an error "Shutdown not allowed on this interface". I have tried going through the GUI via the web and when I tick the enable box next to them and click the submit button, it refreshes and they are un-ticked.
Any ideas?
