You can use the gateway-controller statement to define a connection to a PGC. To configure the information, include the gateway-controller statement at the [edit services pgcp gateway gateway-name] hierarchy level:
- [edit services pgcp gateway gateway-name]
-
gateway-controller gateway-controller-name {
- remote-controller | local-controller;
-
controller-address ip-address;
-
controller-port port-number;
-
-
interim-ah-scheme {
-
algorithm algorithm;
- }
- }
You can configure an IP address as the PGC name. However, the IP address is not used for the connection to the PGC.
To configure your controller as a remote device, include the remote-controller statement.
To configure an IP address for the controller, include the controller-address statement.
To set the authentication algorithm used on connections to the PGC to hashed message authentication code (HMAC), include the interim-ah-scheme statement.
If the underlying network layer does not support IP Security (IPSec), you can use the interim authentication header (AH) scheme to provide security on the PGCP connection. The interim AH scheme defines an authentication header with the H.248.1 protocol header. To use the interim AH scheme, configure the security algorithm that the interim AH scheme uses. Currently, HMAC null is the only algorithm supported.
