Agent Support

•Community: Sets the community strings for the ATM SmartSwitch

•TrapCommunity: Specifies the NMS to which traps are sent

•MyNMAddr: Specifies the IP address through which the switch is managed

•TrustedNMS:Specifies the IP address of the NMS allowed to perform the following commands:

reboot

A.2.2 Default Community Strings

The following is a list of the default community strings used by the ATM SmartSwitch:

•public — Used for all standard SNMP communication

•ILMI — Used by ILMI channels between switches

•zeitnet — Used by the SmartSwitch ATM Administrator program

Caution If the community string zeitnet is changed on the ATM SmartSwitch it must also be changed at the SmartSwitch ATM Administrator. Failure to do so, makes the ATM SmartSwitch unreachable by the SmartSwitch ATM Administrator program.
