Information About Management Access
You can manage the IPS application using the following methods:
• Sessioning to the module from the ASA—If you have CLI access to the ASA, then you can session
to the module and access the module CLI. See the “Sessioning to the Module from the ASA (May
Be Required)” section on page 31-11.
• Connecting to the IPS management interface using ASDM or SSH—After you launch ASDM from
the ASA, your management station connects to the module management interface to configure the
IPS application. For SSH, you can access the module CLI directly on the module management
interface. (Telnet access requires additional configuration in the module application). The module
management interface can also be used for sending syslog messages or allowing updates for the
module application, such as signature database updates.
