DESCRIPTION
Select the version of the SNMP poll messages the ENC sends in order to communicate
with the device.
Enter the port number the ENC uses to transmit and receive SNMP messages to/from the
device.
Type the read-only community string the ENC uses to view information or settings on the
device.
Type the write community string the ENC uses to change settings on the device.
Enter the user name of the administrator account on the device.
Enter the context name configured on the device. This setting should be the same on
both the ENC and device in order to communicate with each other.
Select which hash algorithm (None, MD5 or SHA1) to use to authenticate SNMP packets
transmitted between the ENC and the device. SHA1 is generally considered stronger
than MD5, but it is also slower.
This field is available if you selected MD5 or SHA1 in the Authentication field.
Enter the authentication key, which depends on the authentication algorithm you
selected.
MD5 - a key 16-20 characters long
SHA1 - a key 20 characters long
You can use any alphanumeric characters or ,;|`~!@#$%^&*()_+\{}':./<>=-". If you
want to enter the key in hexadecimal, type "0x" at the beginning of the key. For example,
"0x0123456789ABCDEF" is in hexadecimal format; in "0123456789ABCDEF" is in ASCII
format.
