SNMP 539
Displaying Community Strings
You can display the current SNMP community strings that are assigned.
Configuring Community Strings
A community string is an octet string, included in each SNMP message,
that controls access to system information. The system SNMP agents
internally maintain two community strings that you can configure:
■
Read-only community strings with the default public
■
Read-write community strings with the default private
When an SNMP agent receives an SNMP request, the agent compares the
community string in the request with the community strings that are
configured for the agent:
■
SNMP get , get-next , and set requests are valid if the community string
in the request matches the agent’s read-write community.
■
SNMP get and get-next requests are valid if the community string in
the request matches the agent’s read-only community string or
read-write community string.
Community string
length
When you set a community string, you can specify any value up to
48 characters long.
Administering SNMP Trap Reporting
For network management applications, you can use the Administration
Console to manually administer the trap reporting address information.
■
Displaying Trap Reporting Information — When you display the
trap reporting information, the system displays the various SNMP traps
and their currently configured destinations
.
■
Configuring Trap Reporting — You can add new trap reporting
destination configurations and modify existing configurations. You
can define up to 10 destination addresses and the set of traps that are
sent to each destination address.
The trap numbers that you enter tell the system to send the
corresponding traps to the destination address when the events occur. No
unlisted traps are transmitted.
