Configuring subzones
The
Subzones
page lists all the existing
manually configurable subzones and lets you
add, edit or 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.
To go to the
Subzones
page:
•
VCS configuration > Local Zone > Subzones
.
Click on the subzone you want to configure (or
click
New
to create a new subzone, or click
Delete
to remove a subzone).
Up to 1000 subzones can be configured.
The configurable options are:
Name
Enter the name you want to assign to the
subzone. This name is used when creating links.
Registration policy
Controls whether registrations assigned to the
subzone are accepted. See
Subzone registration
policy
for more details.
Bandwidth
See the
Applying bandwidth limitations to
subzones
section for a description of these
fields.
To add a new subzone using the CLI:
•
xCommand SubZoneAdd
To configure an existing subzone using the CLI:
•
xConfiguration Zones LocalZone
SubZones
Configuring subzone membership rules
The
Subzone membership rules
page lists all
the existing subzone membership rules and lets
you add, edit, delete, enable or disable rules.
Each rule specifies the criteria used to match
an endpoint registering with the VCS into an
appropriate subzone.
To go to the
Subzone membership rules
page:
•
VCS configuration > Local Zone > Subzone
membership rules
.
You can click on a column heading to
sort the list, for example by
Priority
or
Subzone
. If you hover your mouse pointer
over a rule, the rule description (if one has been
defined) appears as a tooltip.
Click on the rule you want to configure (or click
New
to create a new rule, or click
Delete
to
remove a rule).
Up to 3000 subzone membership rules can be
configured.
Enabling and disabling membership rules
When you are making or testing configuration
changes to your membership rules, you may
want to temporarily enable or disable certain
rules. You can do this by selecting the rule's
check box and clicking
Enable
or
Disable
as
appropriate. Any disabled rules still appear in
the rules list but are ignored by the VCS when
processing registration requests.
The configurable options are:
Rule name
A descriptive name for the membership rule.
Description
An optional free-form description of the rule.
Priority
The order in which the rules are applied (and
thus to which subzone the endpoint is assigned)
if an endpoint's address satisfies multiple rules.
The rules with the highest priority (1, then 2,
then 3 and so on) are applied first. If multiple
Subnet
rules have the same priority the rule
with the largest prefix length is applied first.
Alias Pattern Match
rules at the same priority
are searched in configuration order.
Type
The type of address that applies to this rule:
Subnet
: assigns the device if its IP address falls
within the configured IP address subnet.
Alias Pattern Match
: assigns the device if its
alias matches the configured pattern.
Pattern matching is useful, for example,
for home workers on dynamic IP
addresses; rather than having to
continually update the subnet to match
what has been allocated, you can match against
their alias instead.
Subnet address and prefix length
These two fields together determine the range
of IP addresses that will belong to this subzone.
(Applies only if the
Type
is
Subnet
.)
The
Address range
field shows the range of
IP addresses to be allocated to this subzone,
based on the combination of the
Subnet
address
and
Prefix length
.
Pattern type
How the pattern string must match the alias for
the rule to be applied. (Applies only if the
Type
is
Alias Pattern Match
.)
Exact
: the entire string must exactly match the
alias character for character.
Prefix
: the string must appear at the beginning
of the alias.
Suffix
: the string must appear at the end of the
alias.
Regex
: the string is treated as a regular
expression.
Pattern string
The pattern against which the alias is compared.
(Applies only if the
Type
is
Alias Pattern Match
.)
Target subzone
The subzone to which an endpoint is assigned if
its address satisfies this rule.
State
Indicates if the rule is enabled or not.
To add a new membership rule using the CLI:
•
xConfiguration
SubZoneMembershipRuleAdd
To configure membership rules using the CLI:
•
xConfiguration Zones LocalZone
SubZones MembershipRules
If an endpoint’s IP address or alias does
not match any of the membership rules,
it is assigned to the Default Subzone.
