Utilities
BCM450 provides the following utilities:
•BCM Monitor—BCM Monitor is a stand-alone diagnostic application that the system administrator can use to view real-time system and IP telephony information about BCM450 systems.
•Ping—Ping (Packet InterNet Groper) is a utility that you can use to verify that a route exists between the BCM450 and another device.
•Route trace—You can use Trace Route to measure round-trip times to all hops along a route. This helps you to identify bottlenecks in the network.
•Ethernet activity—The Ethernet Activity panel is a utility that you can use to view ethernet activity in the BCM450 system.
For information about utilities, see the “BCM450 Utilities” chapter in the BCM450 Administration and Security Guide (NN40160-601).
