To add or delete SNMP management entity addresses:

1.To add an SNMP management entity address, issue a Server SNMP Manager command with the Add parameter and the management entity’s IP address. You may deﬁne up to four SNMP management entity addresses, using separate commands.

SERVER SNMP MANAGER ADD <ip_address>

When you deﬁne at least one SNMP manager, SNMP requests are processed if they are from one of the deﬁned SNMP managers. If a request is not from one of the deﬁned SNMP managers, the SNMP request is discarded.

2.To delete an SNMP management entity address, issue a Server SNMP Manager command with the Delete parameter and the management entity’s IP address.

SERVER SNMP MANAGER DELETE <ip_address>

If no management entities are defined, any SNMP manager may access the MIB. For more information, see Server SNMP Manager command in Chapter 5.

To enable or disable SNMP traps:

1.To enable SNMP traps, issue a Server SNMP Trap command with the Enable parameter.

SERVER SNMP TRAP ENABLE

The CCM will display a numbered list of traps that are currently disabled with a prompt requesting you to select trap(s) to enable. Indicate the traps to be enabled by entering a trap’s list number, several numbers separated by commas, a range of numbers separated by a dash or a combination

of numbers with commas and dashes. To enable all traps, type ALL. To cancel the command, press Enter.

- or -

To enable all SNMP traps, issue a Server SNMP Trap command with the Enable and All parameters. In this case, the numbered list is not displayed.

SERVER SNMP TRAP ENABLE ALL

2.To disable SNMP traps, issue a Server SNMP Trap command with the Disable parameter.

SERVER SNMP TRAP DISABLE

The CCM will display a numbered list of traps that are currently enabled with a prompt requesting you to select trap(s) to disable. Indicate the traps to be disabled by entering a trap’s list number, several numbers separated by commas, a range of numbers separated by a dash or a combination

of numbers with commas and dashes. To disable all traps, type ALL. To cancel the command, press Enter.
