Default Settings
By default the Local Zone and all other configured zones have a
Match 1 configured with a Mode of AlwaysMatch . All remaining
matches will be set to Disabled . This means that (unless you
make any changes) the zone will be queried for the original alias,
with no transforms applied.
The difference between the default settings for each type of
zone is the
Priority assigned to Match 1 . The default priorities
are:
Local Zone • : 50
Neighbor • , Traversal Client or Traversal Server zone : 100
ENUM • or DNS zone : 150
This default configuration means that the Local Zone will be
searched first for all aliases. If not found locally, all Neighbor,
Traversal Client and Traversal Server zones will then be
searched, and if they cannot locate the alias the request will be
sent to any DNS and ENUM zones.
You can change the default
Match 1 Mode and Priority and add
additional Matches for all zones, including the Local Zone.
Configuring Zone Searches and Transforms
To configure when a zone will be searched and any transforms
that will be applied before the search request is sent:
Local Zone
VCS Configuration > Local Zone > Matches • .
You will be taken to the Local Zone Matches page.
xConfiguration Zones LocalZone Match [1..5 • ]
External Zones
VCS Configuration > Zones • .
You will be taken to the Zones page.
Click on the zone you wish to configure (or New to create
and configure a new zone). You will be taken to the Edit Zone
page.
Scroll down until you get to the
Match1 section.
xConfiguration Zones Zone [1..200] Match [1..5 • ]
Pattern behavior
(Applies only if the Mode is PatternMatch .)
Determines if and how the matched part of the
alias will be modified. Options are:
Leave : the alias will not be modified.
Strip : the matching prefix or suffix will be
removed from the alias.
Replace : the matching part of the alias will be
substituted with the text in the Replace String .
Pattern type
(Applies only if the Mode is PatternMatch .)
Determines the way in which the string must
match the alias. Options are:
Exact : the string must 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 will be treated as a regular
expression.
Priority
Determines the order in which the zone will be
sent a search request. Zones with priority
1
matches are searched first, followed by priority
2 , and so on. More than one match can be
assigned the same priority; in this case the
matching zones will be queried simultaneously.
Replace string
(Applies only if the Mode is
PatternMatch and Pattern
Behavior is Replace .)
Specifies the string to be
used as a substitution for the
part of the alias that matched
the pattern.
Pattern string
(Applies only if the Mode is PatternMatch .)
Specifies the pattern against which the alias is
compared.
Mode
Determines if and when a query will be sent to
this zone. Options are:
AlwaysMatch : the zone will always be queried.
PatternMatch : the zone will only be queried
if the alias queried for matches the specified
Pattern String .
Disabled : this match is not used. If all 5
matches for a zone are disabled, the zone will
never be queried.
