Table 5-16. SNMP NMS Security Options (1 of 2)
NMS IP Validation
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether security checks are performed on the IP address of SNMP
management systems attempting to access the node. Allows access only if IP address
of the sending manager is listed on the SNMP NMS Security Options screen.
Enable – Performs security checks.
Disable – Does not perform security checks.
Number of Managers
Possible Settings: 1 – 10
Default Setting: 1
Specifies the number of SNMP management systems that are authorized to send
SNMP messages to the T1 access unit. An IP address must be configured for each
management system allowed to send messages. Configure the IP addresses in the
NMS
n IP Address configuration option.
1 – 10 – Specifies the number of managers allowed to send SNMP messages.
NMS n IP Address
Possible Settings: 000.000.000.000 – 223.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the IP address that identifies the SNMP manager(s) authorized to send SNMP
messages. If an SNMP message is received from the NMS whose IP address does not
match an address contained in this field, access is denied and an authenticationFailure
trap is generated. If a match is found, the type of access (read-only or read/write) is
determined by the corresponding access level.
000.000.000.000 – 223.255.255.255 – Adds or changes the NMS IP address. The first
digit (i.e.,
xxx.255.255.255) cannot be 127; 127 is a reserved number.
Clear – Clears the NMS IP address and fills the address with zeros
(i.e., 000.000.000.000).
