n
the subnet or alias pattern matching configuration
n
the subzone to which endpoints whose addresses satisfy this rule are assigned
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
Usage tips
Rule name
A descriptive name for the membership rule.
Description
An optional free-form description of the rule.
The description appears as a tooltip if you
hover your mouse pointer over a rule in the
list.
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
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.
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.
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
.
Applies only if the
Type
is
Subnet
.
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
regular expression
.
Applies only if the
Type
is
Alias pattern
match
.
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.
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.
