Setting Up an SNMP Management Station
An SNMP management station is not provided with Equalizer. In order to use SNMP to manage an
Equalizer, a third-party management console must be installed and configured on a machine that can
access the Equalizer system. Configuration procedures are specific to the management console used.
At a minimum, the SNMP management console needs to be configured to:
• Use the Equalizer’s IP address and port 161 for SNMP requests.
•Use the community string specified in the above procedure.
• Use the address and port specified in the above procedure for SNMP traps (usually port 162 is
used for this purpose, but this can be configured as shown in the above procedure).
• Use the Equalizer MIB definitions; these need to be loaded into the management console,
following the instructions for the console. The Equalizer MIB source files are located at:
http://<Equalizer-ip>/eqmanual/cpsreg.my
http://<Equalizer-ip>/eqmanual/cpsequal.my
In the above, <Equalizer-ip> is the IP address of the Equalizer. On the Equalizer, these are
located in the directory /usr/local/www/eqmanual.
MIB Description
Equalizer’s Management Information Base (MIB) contains five major sections. These sections
describe Equalizer’s siblings (failover), configuration and status, clusters, servers, and events. Each
object in the MIB contains a description field that describes the object’s purpose. All of the MIB
objects are read-only; that is, SNMP Set operations are not supported.
The following is a summary description of the Equalizer MIB. The MIB source files contain
detailed comments for each variable; these comments may also be displayed by the MIB browser
when a variable is accessed.
Enable server
up/down events
This checkbox controls two traps, cpsSysEqServerDownEv and
cpsSysEqServerUpEv. Equalizer triggers these traps when it detects
either a server failure or a response from a failed server.
Enable sibling
events
This checkbox controls two traps, cpsSysEqSiblingContactLostEv
and cpsSysEqSiblingContactOkayEv. Equalizer triggers these traps
whenever it is configured as part of a failover pair and it either loses
contact or regains contact (respectively) with its sibling.
Enable failover
events
This checkbox controls one trap, cpsSysEqAssumedPrimaryRoleEv.
Equalizer sends this trap whenever it assumes primary status.
Enable partition
events
This checkbox controls one trap, cpsSysEqPartitionDetectedEv.
Equalizer sends this trap whenever it is in failover mode and detects that
both Equalizers have assumed primary status.
