Traffic classification using NBAR is configured using which IOS command?
A.
router(config-cmap)# match protocol {protocol-name}
B.
router(config-if)# ip nbar protocol-discovery
C.
router(config)# ip nbar port-map {protocol} [tcp|udp] {port-number} {port-number} ….
D.
router(config)# ip nbar pdlm {pdlm-file}
Explanation:
protocol – Allows for the matching of certain predefined protocols. Network-based application recognition (NBAR) is a new classification engine that can recognize a large number of applications based on both static and dynamically assigned port numbers. On routers that support NBAR, the list of protocols is extensive,
