the subnet or alias pattern matching configuration

the subzone to which endpoints whose addresses satisfy this rule are assigned
n
Note that if an endpoint's IP address or registration alias does not match any of the membership rules, it is
assigned to the Default Subzone.
Up to 3000 subzone membership rules can be configured.
The configurable options are:
Field Description
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.
Type Determines how a device's address is checked:
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.
Subnet These two fields together determine the range of
address and IP addresses that will belong to this subzone.
Prefix length
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. Options are:
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: treats the string as a
Pattern string The pattern against which the alias is compared.
Target The subzone to which an endpoint is assigned if
subzone its address satisfies this rule.
State Indicates if the rule is enabled or not.

Usage tips
The description appears as a tooltip if you
hover your mouse pointer over a rule in the
list.
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.
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.
Applies only if the Type is Subnet.
Applies only if the Type is Alias pattern
match.
regular expression.
Applies only if the Type is Alias pattern
match.
Use this setting to test configuration
changes, or to temporarily disable certain
rules. Any disabled rules still appear in the
rules list but are ignored.
