The Search rules page lists all the existing search rules. It is used to add, edit, delete, enable and
disable rules.
Each rule specifies the criteria used to match an alias in the source query before sending the query
on to a target zone. The rule also specifies any zone transforms to apply to the alias.
To go to the Search rules page:

•

VCS configuration > Search rules > Rules.

To configure search rules using the CLI:

•

xConfiguration Zones Policy SearchRules

Note that you can click on a column heading to sort the list, for example by Target zone or
Priority. If you hover your mouse pointer over a search 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).

Enabling and disabling search rules

When you are making or testing configuration changes to your search 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 search rules list but
are ignored by the VCS when processing search requests.

Configuration options

The configurable options are:

Rule name

A descriptive name for the search rule.

Description

An optional free-form description of the search rule.

Priority

The order in the search process that this rule is applied, when compared to the priority of the other
search rules. All Priority 1 search rules are applied first, followed by all Priority 2 search rules, and
so on. More than one rule can be assigned the same priority, in which case any matching target
zones are queried simultaneously.
Different default priorities are assigned depending on the type of the Target zone:

•

Local Zone: 50

•

Neighbor, traversal client or traversal server zone: 100

•

ENUM or DNS zone: 150

This default configuration means that the Local Zone is searched first for all aliases. If the alias is
not found locally, all neighbor, traversal client and traversal server zones are searched, and if they
cannot locate the alias the request is sent to any DNS and ENUM zones.

Source

Specifies the sources of the requests for which this rule applies.
Any: locally registered devices, neighbor or traversal zones, and any non-registered devices.
All zones: locally registered devices plus neighbor or traversal zones.
Local Zone: locally registered devices only.

Mode

Determines whether a query is sent to the Target zone, based on the given alias.
Alias Pattern Match: queries the zone only if the alias matches the corresponding Pattern type and
Pattern string.
Any Alias: queries the zone for any alias (but not IP address).
Any IP Address: queries the zone for any given IP address (but not alias).
