Adding option keys using the web interface
To add an option key:
1.
In the Add option key field, enter the key that has been provided to you for the option you want to add.
2.
Click Add option.
The following option keys require that you restart the VCS before the option key takes effect:
■
Traversal Server
■
Starter Pack
■
Expressway Series
■
Advanced Account Security (if moved into FIPS mode)
When a restart is required, you receive an alarm on the web interface, which remains in place as a notification until
you restart the system. However, you can continue to use and configure the VCS in the meantime.

Adding option keys using the CLI
To return the indexes of all the option keys that are already installed on your system:
xStatus Options
To add a new option key to your system:
xConfiguration Option [1..64] Key
Note:
when using the CLI to add an extra option key, you can use any unused option index. If you chose an existing
option index, that option will be overwritten and the extra functionality provided by that option key will no longer exist.

About Security Certificates
For extra security, you may want to have the VCS communicate with other systems (such as LDAP servers, neighbor
VCSs, or clients such as SIP endpoints and web browsers) using TLS encryption.
VCSs, or clients such as SIP endpoints and web browsers) using TLS encryption.
For this to work successfully in a connection between a client and server:
■
The server must have a certificate installed that verifies its identity. This certificate must be signed by a
Certificate Authority (CA).
Certificate Authority (CA).
■
The client must trust the CA that signed the certificate used by the server.
The VCS allows you to install a certificate that can represent the VCS as either a client or a server in connections
using TLS. The VCS can also authenticate client connections (typically from a web browser) over HTTPS. You can
also upload certificate revocation lists (CRLs) for the CAs used to verify LDAP server and HTTPS client certificates.
