•Q.Can I restore a backup that I made on a WLSE running beta software to a WLSE running released software?

•Q.Can I restore a backup from a WLSE 1105 to a WLSE 1130 series?

•Q.Can I upgrade from beta software to released software?

•Q.Are there any special considerations when performing actions on a redundant cluster?

•Q.Why are the WLSEs in my redundant environment exhibiting problems such as duplicate IPs, etc., and why am I having trouble accessing them with virtual IP addresses?

•Q.Do I have to get a signed certificate from a certificate authority in order to use WLSE security features such as SSL (HTTPS)?

•Q.How do I change the password used by WLSE Redundancy?

•Q.How do I change the user ID used by WLSE redundancy?

•Q.What are the different redundancy states?

Q.How can I verify the status of the database?

A.You can verify that the WLSE database is running by using the show process CLI command. If the command output includes the db2sync process, the database is running.

Q.What are the rules for WLSE user names and passwords?

A.User names can be up to 32 characters long. They cannot begin with a number (unless the user is not using the CLI). You can use the alphanumeric characters (A-Z, a-z, 0-9) and numerous special characters. For a complete list of the characters allowed, see the Naming Guidelines appendix in the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.13. Passwords are unlimited in length and you can use all characters except the single quote, double quote, and dollar sign. Both user names and passwords are case-sensitive.

Q.Can I restore a backup that I made on a WLSE running beta software to a WLSE running released software?

A.No.

Q.Can I restore a backup from a WLSE 1105 to a WLSE 1130 series?

A.Yes.

Q.Can I upgrade from beta software to released software?

A.No.

Q.Are there any special considerations when performing actions on a redundant cluster?

A.Yes, there are special procedures for backup/restore, upgrading the software, and a few other operations. See the online help for the redundancy feature or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.13 on Cisco.com.

Q.Why are the WLSEs in my redundant environment exhibiting problems such as duplicate IPs, etc., and why am I having trouble accessing them with virtual IP addresses?

A.If DNS is enabled, then it is possible the DNS servers specified for use by the WLSE are not operational, not reachable due to a network outage, or not configured correctly. If the DNS server is not set up correctly, proper communication between the Active and Standby WLSEs will not be maintained, and will result in the status for both WLSEs becoming Active-Lost-Standby.
