I am experiencing an issue with end host being discovered on a cisco 4510. Anything connected to modules 9 or 10 are not discovered in User Tracking. The switch is running: Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.02.01.SG RELEASE SOFTWARE (fc4). Has anyone seen this behavior or know why this is happening? TIA
