Diagnostics Tools for IP
Using Diagnostic Tools for IP (H.323)
Using the Diagnostics Tools for IP will require a PC and setting up a
telnet session towards the PC and the video system.
Q.931
To show Q.931 trace during a call you need to issue the command
‘
syslog on
’. One can get traces for RAS, Q.931 and H.245 with this
command. It is a complex trace and requires an extensive knowledge in
H.323 signaling to be understood.
Ping
Ping is used to see if the system is able to reach a specific IP-address,
using a mechanism in IP called ICMP. If the system is unable to register
to its Gatekeeper, or if it is unable to dial a specific endpoint, one can
use ping to see if there is at least an IP-route to the Gatekeeper or to the
endpoint. In case you have problems, one would first ping the default
gateway, then the Gatekeeper, and then the other endpoint.
Traceroute
Traceroute does exactly that; it traces the route an IP-packet takes to
reach its destination and displays all router hops. Traceroute is very
useful for seeing exactly where there is a routing-problem in the IP-
network, and for checking where transport-delay is introduced.
Layer 4 Ports used in H.323 calls
The layer 4 ports used by the system in a H.323 call can be defined as
follows:
•
Dynamic: The ports are allocated at random from 2048 to 65535.
•
Dynamic H323 ports are allocated at random from 11000 to 65535.
•
Static: Will use the predefined layer 4 ports listed in the tables to the
right.

* While using MultiSite, if a site is disconnected and reconnected without
terminating the entire conference, the next site to be connected will have a H.245
port outside of the specified range. If this functionality is required through a
firewall, the range of TCP ports can be extended past 5564. However, if a site is
disconnected and reconnected, without ending the conference enough times one
can quickly end up outside of this range again.
