Encryption
Specify the type of air link security to apply to this BHM:
• Encryption Disabled provides no encryption on the air link. This is the default
mode.
• Encryption Enabled provides encryption, using a factory-programmed secret
key that is unique for each module.
NOTE:
In any BH link where encryption is enabled, the BHS briefly drops registration
and re-registers in the BHM every 24 hours to change the encryption key.
BHS Display of BHM Evaluation Data
You can use this field to suppress the display of data (Disable Display) about this BHM
on the BHM Evaluation tab of the Tools page in the BHS.
Web, Telnet, FTP Session Timeout
Enter the expiry in seconds for remote management sessions via HTTP, telnet, or ftp
access to the BHM.
IP Access Control
You can permit access to the BHM from any IP address (IP Access Filtering Disabled)
or limit it to access from only one, two, or three IP addresses that you specify (IP Access
Filtering Enabled). If you select IP Access Filtering Enabled, then you must populate
at least one of the three Allowed Source IP parameters or have no access permitted
from any IP address, including access and management by Prizm.
Allowed Source IP 1 to 3
If you selected IP Access Filtering Enabled for the IP Access Control parameter, then
you must populate at least one of the three Allowed Source IP parameters or have no
access permitted to the BHM from any IP address. You may populate as many as all
three.
If you selected IP Access Filtering Disabled for the IP Access Control parameter, then
no entries in this parameter are read, and access from all IP addresses is permitted.
The Security tab also provides the following buttons.
Save Changes
When you click this button, any changes that you made on the Configuration page are
recorded in flash memory. However, these changes do not apply until the next reboot of
the module.
