Configuring the registration Deny List
The Registration Deny List page (Configuration > Registration > Deny List) shows the endpoint aliases
and alias patterns that are not allowed to register with the VCS. Only one of an endpoint's aliases needs to
match an entry in the Deny List for the registration to be denied.
To use the Deny List, you must select a Restriction policy of Deny List on the Registration configuration
page.
The configurable options are:
Field Description Usage tips
Description An optional free-form description
of the entry.
Pattern
type
The way in which the Pattern
string must match the alias.
Options are:
Exact: the alias must match the
pattern string exactly.
Prefix: the alias must begin with
the pattern string.
Suffix: the alias must end with
the pattern string.
Regex: the pattern string is a
regular expression.
You can test whether a pattern matches a particular alias by
using the Check pattern tool (Maintenance > Tools > Check
pattern).
Pattern
string
The pattern against which an
alias is compared.
