Failover Misconfiguration
Misconfiguration of failover groups might result in multiple master appliances or other failover 
problems. Diagnose failover problems using the 
testfailovergroup
 subcommand of the CLI 
failoverconfig
 command.
For example:
wsa.wga> failoverconfig
Currently configured failover profiles:
1.      Failover Group ID: 61
        Hostname: failoverV4P1.wga, Virtual IP: 10.4.28.93/28
        Priority: 100, Interval: 3 seconds
        Status: MASTER
Choose the operation you want to perform:
- NEW - Create new failover group.
- EDIT - Modify a failover group.
- DELETE - Remove a failover group.
- PREEMPTIVE - Configure whether failover is preemptive.
- TESTFAILOVERGROUP - Test configured failover profile(s)

Failover Issues on Virtual Appliances 
For deployments on virtual appliances, ensure that you have configured the interface/ virtual switch on 
the hypervisor to use promiscuous mode. 
FTP Problems

URL Categories Do Not Block Some FTP Sites
When a native FTP request is transparently redirected to the FTP Proxy, it contains no hostname 
information for the FTP server, only its IP address. Because of this, some predefined URL categories 
and Web Reputation Filters that have only hostname information will not match native FTP requests, 
even if the requests are destined for those servers. If you wish to block access to these sites, you must 
create custom URL categories for them using their IP addresses.
