## KMC Practices

• As your data storage grows, the number of tape keys will also grow over time. This is especially the case when you select the unique key mode. It is a good practice to store only active keys in the Cisco KMC database.

• To ensure redundancy and availability, it is important to back up your Cisco KMC database regularly.

• The Cisco KMC listens for key updates and retrieves requests from switches on a TCP port. The default port is 8800; however, the port number can be modified in the smeserver.properties file.
