Hi All,
I have enabled 'ip nbar protocol-discovery' in our router and when I checked the traffic generated I can see much of it came from unknown protocol as shown in the attachment. The router is using NBAR software version 13 and no PDLM installed, details is on the attachment. The router is Cisco 2901 and the IOS is :c2900-universalk9-mz.SPA.152-4.M6.bin. Can you help me what else I need to install to see the details of the unknown protocols?
John
