I have a Cisco 6506 that is one of my ciores switches in company. I ran into some UDLD issues when psanning tree detected a loop and disabled all the fiber interfaces in my datacnet. Nevethless, nos that I have disabled udld my management vlan 99 = 10.1.99.x/24 is having issues and I can't the ip address of 10.1.99.1/24 on my 6505 switch. My first step was recreating the vlan (no workie) then assign a different ip (no workie). Any ideas?
