About The Default Subzone; Configuring Subzones - Cisco TelePresence Administrator's Manual

for 5 traversal calls you must ensure that the range of ports configured for traversal media is at least 200. If
you add extra traversal calls to your system, you must also ensure that the range of ports available is
sufficient.

About the Default Subzone

The Default Subzone page
bandwidth restrictions on calls involving endpoints in the Default Subzone, and to specify the Default
Subzone's registration, authentication and media encryption policies.
When an endpoint registers with the VCS, its IP address and alias is checked against the subzone
membership rules and it is assigned to the appropriate subzone. If no subzones have been created, or the
endpoint's IP address or alias does not match any of the subzone membership rules, it is assigned to the
Default Subzone (subject to the Default Subzone's Registration policy and Authentication policy).
The use of a Default Subzone on its own (without any other manually created subzones) is suitable only if
you have uniform bandwidth available between all your endpoints. Note that if your Local Zone contains two
or more different networks with different bandwidth limitations, you should configure separate subzones for
each different part of the network.

Configuring subzones

The Subzones page (VCS configuration > Local Zone >
configured on the VCS, and allows you to create, edit and delete subzones. For each subzone, it shows how
many membership rules it has, how many devices are currently registered to it, and the current number of
calls and bandwidth in use. Up to 1000 subzones can be configured.
After configuring a subzone you should set up the
an endpoint device is assigned to when it registers with the VCS as opposed to defaulting to the
Subzone.
The configurable options are:
Field / section Description
Registration When an endpoint registers with the VCS, its IP address and alias is checked against the
policy subzone membership rules and it is assigned to the appropriate subzone. If no subzones have
been created, or the endpoint's IP address or alias does not match any of the subzone
membership rules, it is assigned to the Default Subzone.
In addition to using a
with the VCS, you can also configure a subzone's Registration policy as to whether it will
accept registrations assigned to it via the subzone membership rules.
This provides additional flexibility when defining your registration policy. For example you can:
Deny registrations based on IP address subnet. You can do this by creating a subzone with
n
associated membership rules based on an IP address subnet range, and then setting that
subzone to deny registrations.
Configure the Default Subzone to deny registrations. This would cause any registration
n
requests that do not match any of the subzone membership rules, and hence fall into the
Default Subzone, to be denied.
Note that registration requests have to fulfill any registration restriction policy rules before any
subzone membership and subzone registration policy rules are applied.
