6.2.3 Inventory Device Details - Interface

Use this screen to view the current port information of the selected device.
ENC User's Guide
DESCRIPTION
This field is available if you selected MD5 or SHA1 in the Authentication field.
Select which encryption algorithm to use for SNMP packets transmitted between the ENC
and the device.
None - no encryption key or algorithm
DES - a 56-bit key with the DES encryption algorithm
AES - a 128-bit key with the AES encryption algorithm
This field is available if you selected DES or AES in the Privacy field.
Enter the encryption key with the length according to the Privacy setting.
Select this to have the ENC poll its managed devices periodically to update their status in
the ENC. Clear this to disable it.
Select which method (SNMP, Ping) the ENC uses to poll the device's status.
Select how often the ENC sends a poll message to the device.
You can use this and the following two Status fields to customize a threshold the ENC
uses to determine whether the device is running normally or not. Type the MIB object ID
of the variable for the criteria. This is an example for the threshold.
"1.3.6.1.4.1.890.1.6.1.1.1.0 (sysCPUUsage) < 98" means the device is running normally
when the CPU usage is less than 98%. If the CPU usage goes to 98% or above, the
device is overloaded.
You can also click the magnifier icon and find the object to have the ENC automatically
display the object ID in this field.
Select the comparison expression for the threshold. The available options are greater
than (>), equal to (=), and less than (<).
Enter the value for the threshold. If the variable's value stays within the set threshold,
the device is online to the ENC. Otherwise, the ENC changes the device's status to offline.
Select this to enable TCP port scan for the device, if you want to track whether a service
is available for access.
Select this to have the ENC detect whether web service is available on the device.
Select this to have the ENC detect whether FTP service is available on the device.
Select this to have the ENC detect whether Telnet service is available on the device.
Select this to have the ENC detect whether mail service (SMTP) is available on the
device.
Select this and configure the service's name and port number to have the ENC detect
whether the service is available on the device.
Click this to save the changes.
Click this to exit this screen and go back to the previous screen.
