Media Flow Controller Troubleshooting
•
Check the network path to a destination with traceroute:
a. At the command prompt, type traceroute <IP_address_of_remote_network_host>,
and then press ENTER.
b. Examine the results to determine the length of time that the packet took to reach each
network segment and the point at which the connection may stop working.

Testing Media Flow Controller Delivery Functions
This test, using
is using a configured namespace to fetch and deliver content via HTTP or NFS, and Media
Flow Controller caching mechanisms.
To perform this test you need a client machine with Wget installed that can also serve as the
origin server, and a Media Flow Controller, and connectivity between the two of them. The
setup for this example procedure includes creating data files (test.txt) and placing them in a
directory (testresults/joe) on a Unix machine with Wget installed, serving as client and origin
(172.16.254.1 / sv05).
The actions for this example procedure are configuring a namespace (testHttp), requesting
files via the Media Flow Controller (172.16.254.2 / test-vos), and observing results using
show counters and the accesslog on the Media Flow Controller Web interface.
