Configuring Traversal Client Zones - Cisco TelePresence Video Communication Server Administrator's Manual

Field Description
Zone profile Determines how the zone's advanced
settings are configured.
Default: uses the factory defaults.
Custom: allows you to configure each
setting individually.
Preconfigured profiles: choose one of the
preconfigured profiles to automatically use
the appropriate settings required for
connections to that type of system.
The default is Default.

Configuring traversal client zones

To traverse a firewall, the VCS must be connected with a traversal server (for example a VCS
Expressway or a TANDBERG Border Controller).
In this situation your local VCS is a traversal client, so you create a connection with the traversal
server by creating a traversal client zone on your local VCS. You then configure the client zone with
details of the corresponding zone on the traversal server. (The traversal server must also be
configured with details of the VCS client zone.)
After you have neighbored with the traversal server you can:
use the neighbor as a traversal server
n
query the traversal server about its endpoints
n
apply transforms to any queries before they are sent to the traversal server
n
control the bandwidth used for calls between your local VCS and the traversal server
n
For full details on how traversal client zones and traversal server zones work together to achieve
firewall traversal, see About firewall
An NTP server must be configured for traversal zones to work.
The configurable options for a traversal client zone are:
Field Description
Configuration section:
Name The name acts as a unique identifier, allowing
you to distinguish between zones of the same
type.
Type The nature of the specified zone, in relation to
the local VCS. Select Traversal client.
Hop count The hop count is the number of times a
request will be forwarded to a neighbor
gatekeeper or proxy (see the
section for more information). This field
specifies the hop count to use when sending
a search request to this particular zone.

Usage tips
See Zone configuration:
advanced settings for details on
the Advanced settings.
Do not use the Custom option or
configure the individual Advanced
settings except on the advice of
Cisco customer support.
Usage tips
After a zone has been created, the
Type cannot be changed.
If the search request was received
from another zone and already has
a hop count assigned, the lower of
the two values is used.
