SNMP NMS Security Options
NMS IP Validation
Possible Settings: Enable, Disable
Default Setting: Disable
Determines if security checks are performed on the IP address of any SNMP
management system that attempts to access the node.
Enable – Performs security checking. Allows access only if the sending manager’s
IP address has been entered on the NMS IP address list below.
Disable – No security checking of incoming SNMP messages.
Number of Managers
Possible Settings: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Default Setting: 1
Set the number of SNMP managers that are authorized to send SNMP messages. The
IP address of each SNMP management system must be entered in the next option.
1 to 10 – Specifies the number of SNMP managers allowed to send SNMP messages.
NMS
n IP Address
Possible Settings: 001.000.000.000 – 223.255.255.255, Clear
Default Setting: 001.000.000.000
Enter an IP address for each of the managers set in the previous option. “
n” is the
number of the manager (1 to 10). Use the next option to establish the security level for
each SNMP manager.
NOTE:
When an SNMP message is received from an IP address that does not
match the IP address entries in this option, access is denied and an
“authenticationFailure” trap is generated.
001.000.000.000 – 223.255.255.255 – Sets the NMS IP address. The range for the first
byte is 001 to 223, with the exception of 127. The range for the remaining three bytes is
000 to 255.
Clear – Clears the IP address and sets to all zeros.
Access Level
Possible Settings: Read, Read/Write
Default Setting: Read
Set the access level for each IP address created in the previous option.
Read – Allows a read-only access (SNMP Get) to accessible MIB objects.
Read/Write – Allows both an SNMP Get and Set to MIB objects. Write access allowed
to all MIB objects specified as read-write in the MIB RFC. This access level is
overridden by the Community Name’s access level for the SNMP Manager, if the
Community Name access level is Read.
