You can display information about the Replication Server network-based security using the admin security_property and admin security_setting commands.
admin security_property[, security_mechanism]
Replication Server displays the name of supported security mechanisms, the security services available for that mechanism, and whether or not those services are supported at your site.
Use admin security_setting to determine the status of supported security services.
