Table 5-5. SNMP Menu Options (1 of 2)
Security (SNMP Security) A-F-A
Gives the user the ability to configure allowable NMS IP addresses and to configure
SNMP agent.
Although SNMP community strings (if they are changed from the defaults) provide a
measure of security for unauthorized managers, enabling IP address security and
entering the IP address of up to five authorized SNMP managers provides a much
higher level of security. When IP address security is enabled, the source address of any
SNMP message addressed to any of the card’s IP addresses (in either the management
or service domain) will be checked against the authorized list and will be dropped if
there is no match.
IP Address Security – Enable/Disable (Default = Disable).
H Enabling allows DSLAM to accept SNMP messages from SNMP managers whose
IP source addresses have been entered in the IP Address field.
NOTE: If enabled with no IP address specified or with all addresses set to No
Access (NA) permission, then there is no SNMP connectivity to the MCC
card.
H Disabling stops IP address checking and allows the card to respond to a SNMP
query from any source with a proper community string.
IP Address –
nnn.nnn.nnn.nnn
format. Enter up to five IP source addresses of NMS
managers.
Access – ReadOnly(ro)/ReadWrite(rw)/NoAccess(na). Permission to be granted to
each NMS manager.
Logical Entities (SNMP Logical Entities) A-F-B
This screen displays default system information contained in the logical table of the
Entity MIB. Only the Community Name fields can be edited; others are read only.
H I (Index) column shows the index number of DSL cards 1 through 18.
