Configuring AES encryption in an operational link
Configuring link encryption over an operational link will necessitate a service outage.
Therefore, the configuration process should be scheduled during a period of low link
utilization.
To enable AES encryption over an operational link, proceed as follows:
1
Open two browsers.
2
Log into the web interfaces at each end of the link.
3
Perform Configuring AES encryption on page 6-29 at each unit.
4
Reboot both ends of the link.
5
The software is designed to allow five seconds so that a user can command both
ends of the link to reboot before the wireless link drops.
To enable AES encryption over an operational 1+1 Hot Standby link:
• Configure licence keys on all CMUs, if required to permit use of encryption. See Task
3: Installing license keys on page 6-21.
• Follow the procedure Changing AES encryption keys on page 7-53.
