The IP Telephony Manager default value for SNMP community string is public for read only and private for read-write. To change the default values, you must first change the community string on the devices and then on IP Telephony Manager.

For security reasons, you cannot view the community strings through IP

Telephony Manager.

For information about changing the community strings, refer to Changing the

SNMP Community Strings, in Chapter 4.

Authorized Stations The Authorized Stations submenu lets you maintain the management and Submenu security functions for the specified station.

The chassis Network Management Card (NMC) contains an authorized access list that lets you limit management capability to certain management stations on your network. After you create entries in the authorized access list, only those management stations can send SNMP requests to that device.

For information about setting the authorizations for a station, refer to Setting

Authorized Stations, in Chapter 2.

To set up an authorized access list:

1Open a console window for the device whose authorized access list you want to change.

2From the Security menu, select Authorized Stations. The Authorized Stations window appears.
