553-3001-225 Standard 1.00 May 2006
Please note that this is a restricted feature. The following conditions must
be met:
• The client firmware must support Secure UNIStim. If not, you must
update the firmware prior to using this feature.
• The client must not already have a primary key (S1 and S2 keys must be
all ‘f’s). If it has, the autoload does not work again. This limitation
minimizes security risks.
• The client must first connect in non-secure mode.
• You must configure the client policy in the Web UI to allow Secure
UNIStim upgrades.
After successful connection, check client primary key configuration to ensure
the primary key is loaded. See “Private key updates” on
page 154 .
Session caching
The SMC supports session caching, which enhances the performance of the
client handshake. When the UNIStim IP phone logs in a second time, the
server reuses the previous master key and session to create a new session key.
This prevents the TPS from generating another master key. Session caching
is enabled as part of the UNIStim policy.
Administrative tools
You can manage the SMC using the following administrative tools:
• Web User Interface (Web UI)
• Command Line Interface (CLI)
Note: The CLI must be used for initial configuration. Most tasks, other
than initial configuration, are supported by the Web UI and the CLI;
however, the ease of use makes the Web UI the preferred administration
tool.
Web User Interface (UI)
SMC 2450 supports Web UI, a web-based graphical user interface (GUI) that
offers an alternative to the command line interface (CLI). Web UI
