provides instructions to access the latest Cisco Starent MIB files using a MIB
Browser. An updated MIB file accompanies every StarOS release. For assistance
to set up an account and access files, please contact your Cisco sales or
service representative for additional information.
A MIB Browser
allows the user to pull out data from SNMP enabled devices. You can load
standard and propriety MIBs. The tool allows the user to see the MIB data in a
readable format and also offers the ability to search for a specific OID. The
Browser displays all of the MIBs in a MIB tree which makes it easy to find and
identify all Objects, Traps or Conformances.
Use the following
procedure to view the SNMP MIBs for a specific StarOS build :

The system uses the SNMP to send traps or events to alarm servers on the network. You must configure SNMP settings to communicate with those devices.
Commands used in the configuration samples in this section provide base functionality. The most common commands and keyword options are presented. In many cases, other optional commands and keyword options are available. Refer to the Command Line Interface Reference for complete information.
The SNMP MIB Reference describes the supported MIBs and SNMP traps.
To configure the system to communicate with an alarm server:
The system contact is
the name of the person to contact when traps are generated that
indicate an error condition.
An snmp community string
is a password that allows access to system management information
bases (MIBs). The system can send SNMPv1, SNMPv2c, or
SNMPv3 traps to numerous target devices.
The snmp notif-threshold command
configures the number of SNMP notifications that need to be generated
for a given event and the number of seconds in the monitoring window
size (default = 300), before
the notification is propagated to the SNMP users (default = 100).
The snmp engine-id
local command is optional. It is only required if your network
requires SNMP v3 support. The engine ID uniquely identifies
the SNMP engine and associated SNMP entities, thus providing
a security association between the two for the sending and receiving
The snmp user name is
for SNMP v3 and is optional. There are numerous keyword
options associated with this command.
Use the snmp mib command
to enable other industry standard and Cisco MIBs. To see
a list of supported MIBs, use the Exec mode show snmp server command.
By default SNMP runtime debugging always runs
and consumes CPU cycles for event logging. To control CPU
usage you can set no snmp runtime-debug to disable runtime
debugging. An option to this command allows you to specify
SNMP token values that will locate and parse specified MIBs.
Verifying SNMP Parameters
Run the show snmp server command to verify that the SNMP server information is correctly configured. The following displays a sample output of this command.
The system uses SNMP traps (notifications) to indicate that certain events have occurred. By default, the system enables the generation of all traps. However, you can disable individual traps to allow only traps of a certain type or alarm level to be generated. This section provides instructions for disabling/enabling SNMP traps.
Commands used in the configuration samples in this section provide base functionality. The most common commands and keyword options are presented. In many cases, other optional commands and keyword options are available. Refer to the Command Line Interface Reference for complete information regarding all commands.
To configure SNMP trap generation:
Set parameters by applying the following example configuration:
