Limiting SNMP Access through the IP Addresses of the Managers

The unit provides an additional level of security through validation of the IP addresses.

The SNMP Management option must be enabled. To control SNMP access with IP addresses, follow this menu selection sequence:

Main Menu → Configuration → Management → Security Menu

Refer to Table A-9,SNMP NMS Security Options. The SNMP access can be limited by:

HEnabling NMS IP address checking.

HAdd each IP address and access level.

NOTE:

Do not change or delete the IP address or access level of the NMS performing the sets or enable IP address checking prior to adding the NMS to the table.

Resetting the Termination Unit's COM Port or

Factory Defaults

Misconfiguring the termination unit could render the user interface inaccessible, leaving it in a state where a session cannot be started via the COM port or a Telnet session. If this occurs, the termination unit connectivity can be restored via a terminal directly connected to the COM port.

Two methods can be used to restore access to the user interface:

HReset COM Port ± Allows you to reset the configuration options related to COM port usage. This also causes a device reset, where the termination unit performs a Device Self-Test. No security-related configuration options are changed.

HReload Factory Defaults ± Allows you to reload the Default Factory Configuration, resetting all of the configuration and control settings which causes the current configuration to be destroyed and a device reset. This method is also useful when the user's password(s) have been forgotten.

"Procedure

To reset COM port settings:

1.At the terminal that is directly connected to the unit's COM port, configure the terminal to operate at 9.6 kbps, using character length of 8 bits, with one stop-bit, and no parity.

2.Reset the unit, then immediately and repeatedly press Enter at a rate of about 1 press per second until the System Paused screen appears.

3.Tab to the desired method, and enter yes (or y) for the selected prompt.
