Usage Guidelines The WAAS network is a collection of WAAS device and WAAS Central Manager nodes. One primary
WAAS Central Manager retains the WAAS network settings and provides other WAAS network nodes
with updates. Communication between nodes occurs over secure channels using the Secure Shell Layer
(SSL) protocol, where each node on the WAAS network uses a Rivest, Shamir, Adelman (RSA)
certificate-key pair to communicate with other nodes.
Use the cms config-sync command to enable registered WAAS devices and standby WAAS Central
Manager to contact the primary WAAS Central Manager immediately for a getUpdate (get configuration
poll) request before the default polling interval of 5 minutes. For example, when a node is registered with
the primary WAAS Central Manager and activated, it appears as Pending in the WAAS Central Manager
GUI until it sends a getUpdate request. The cms config-sync command causes the registered node to
send a getUpdate request at once, and the status of the node changes as Online.
Use the cms database create command to initialize the CMS database. Before a node can join a WAAS
network, it must first be registered and then activated. The cms enable global configuration command
automatically registers the node in the database management tables and enables the CMS. The node
sends its attribute information to the WAAS Central Manager over the SSL protocol and then stores the
new node information. The WAAS Central Manager accepts these node registration requests without
admission control and replies with registration confirmation and other pertinent security information
required for getting updates. Activate the node using the WAAS Central Manager GUI.
Once the node is activated, it automatically receives configuration updates and the necessary security
RSA certificate-key pair from the WAAS Central Manager. This security key allows the node to
communicate with any other node in the WAAS network. The cms deregister command removes the
node from the WAAS network by deleting registration information and database tables.
To back up the existing management database for the WAAS Central Manager, use the cms database
backup command. For database backups, specify the following items:
• Location, password, and user ID
• Dump format in PostgreSQL plain text syntax
The naming convention for backup files includes the time stamp.
Note For information on the procedure to back up and restore the CMS database on the WAAS Central
Manager, see the Cisco Wide Area Application Services Configuration Guide.
When you use the cms recover identity word command when recovering lost registration information,
or replacing a failed node with a new node that has having the same registration information, you must
specify the device recovery key that you configured in the Modifying Config Property,
System.device.recovery.key window of the WAAS Central Manager GUI.
Use the lcm command to configure local/central management (LCM) on a WAE. The LCM feature
allows settings that are configured using the device CLI or GUI to be stored as part of the WAAS
network-wide configuration data (enable or disable).
When you enter the cms lcm enable command, the CMS process running on WAEs and the standby
WAAS Central Manager detects the configuration changes that you made on these devices using CLIs
and sends the changes to the primary WAAS Central Manager.
