EncrypTight User Guide
In order to ensure network resiliency, some EncrypTight configurations may have external ETKMSs 
installed in pairs: a primary ETKMS and a backup ETKMS. The ETPM distributes the policies to both 
the primary ETKMS and backup ETKMS. Only the primary ETKMS distributes the keys and policies to 
the PEPs. If a communication failure occurs with the primary ETKMS due to a ETKMS failure or 
network failure, the backup ETKMS assumes the generation and distribution of the keys and policies to 
the PEPs. Once communication with the primary ETKMS is reestablished, the primary resumes the 
distribution of the keys and policies to the PEPs.
CAUTION
Do not add backup ETKMSs as separate appliances in the Appliance Manager in ETEMS. Backup 
ETKMSs should only be specified in the Backup IP Address box in the ETKMS editor. Backup ETKMSs 
are not listed in the Appliance Manager view. If you add a backup ETKMS to the Appliance Manager, you 
can accidentally use it in network sets and policies, which will interfere with the ability of the server to act 
as a backup.
Adding ETKMSs
To add an ETKMS:
1 From the perspective tab, click >> and select Appliance Manager.
2 In the Appliance Manager, select File > New Appliance.
3 Select Product Family > ETKMS and Software Version ETKMS n.n where n.n is the appropriate 
ETKMS version.
If you want to add a local ETKMS, select ETKMS LM and the appropriate software version. Enter 
the ETKMS properties in the ETKMS appliance editor as described in
