Managing the CCM Using SNMP

The CCM provides a set of commands that create and manage SNMP structures for use by third-party network management products. These commands cover the following operations:

•Enabling and disabling SNMP UDP port 161 SNMP processing

•Defining read, write and trap community names

•Defining and deleting up to four SNMP management entity IP addresses

•Enabling and disabling SNMP traps

•Defining and deleting up to four trap destination IP addresses

•Defining, copying and deleting up to ten alert strings for each port

SNMP is disabled by default.

To enable or disable SNMP processing:

1.To enable SNMP processing, issue a Server SNMP command with the Enable parameter. This is the default setting.

SERVER SNMP ENABLE

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

SERVER SNMP DISABLE

For more information, see Server SNMP command in Chapter 5.

To specify SNMP community names:

Issue a Server SNMP Community command, using the Readcomm, Writecomm and Trapcomm parameters to specify community names.

NOTE: The default community names are “public”; if you enable SNMP, you are encouraged to change the community values to prevent access to the MIB.

SERVER SNMP COMMUNITY READCOMM=<name>

WRITECOMM=<name> TRAPCOMM=<name>

Although all three community names default to public, if you specify a trap community name with this command, it must be different from the read and write community names.

For more information, see Server SNMP Community command in Chapter 5.
