What is the default range?
On new installations of X8.1 or later, the default media traversal port range is 36000 to 59999, and is set on
the VCS Control (
the VCS Control (
Configuration > Local Zones > Traversal Subzone
). In Large VCS Expressway
systems the first 12 ports in the range – 36000 to 36011 by default – are always reserved for multiplexed
traffic. The VCS Expressway listens on these ports. You cannot configure a distinct range of demultiplex
listening ports on Large systems: they always use the first 6 pairs in the media port range. On Small/Medium
systems you can explicitly specify which 2 ports listen for multiplexed RTP/RTCP traffic, on the VCS

the media traversal port range from the previous version (could be 50000 - 54999 or 36000 - 59999, depending
on source version). The VCS Expressway retains the previously configured demultiplexing pair (either 2776
& 2777 or 50000 & 50001 by default, depending on upgrade path) and the switch Use configured
demultiplexing ports is set to Yes. If you do not want to use a particular pair of ports, switch Use
configured demultiplexing ports to No, then the VCS Expressway will listen on the first pair of ports in the
media traversal port range (36000 and 36001 by default). In this case, we recommend that you close the
previously configured ports after you configure the firewall for the new ports.

Configuring the Default Subzone
The
Default Subzone
page (
Configuration > Local Zone > Default Subzone
) is used to place bandwidth
restrictions on calls involving endpoints in the Default Subzone, and to specify the Default Subzone's
registration, authentication and media encryption policies.
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).
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 (
Configuration > Local Zone > Subzones
) lists all the subzones that have been
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.
