I have a WLC 4402 plugged into a Catalyst 4507R. My problem is I am unable to ping the WLC from a different VLAN. While reading the document about best practices, it mentions that the fiber port should be configured using dot1q encapsulation but when I try to configure that, I do not get encapsulation as an option. The wierd thing is, other ethernet ports on the switch do have encapsulation configured. Please advise!
