Hello Dennis. I was just browsing Thwack to find some other Brocade polling help and found your request. We ran 6910s and I finally got this working. We just replaced them, but if I remember correctly we had to add a Connection Profile for the 6910. On my system, I go to Settings/All Settings/ then in Product Specific Settings I go to NCM Settings. In Global Device Defaults area I go to Connection Profiles. Create a new profile and provide the profile name, username/password for the switch, No Enable Login and I used Telnet for all other fields. I hope this helps. We aren't running 6910s anymore, but I do still have one I can fire up if you need more help.
