Protocol Discovery

Posted December 19, 2005 by larkspur in Cisco router

You can check and customize what protocols are running through your router with nbar protocol-discovery. This gives you packet count, byte count, 5 min bit rate, and 5 min max bit rate.


First, you need to enable nbar:

routers>en
router#conf t
router(config)#int serial 0
router(conf-if)#ip nbar protocol-discovery

To customize ports:

router(config)#ip nbar custom

To view:

router#sh ip nbar protocol-discovery
