SNMP configuration overview
After the SP Switch Router is powered on and booted, the network administrator logs on to
configure the router as a system. The following is a description of the steps that can be taken
during router configuration. The actual procedure is described in Chapter 2.
The configuration for the snmpd daemon must be updated to identify the SP SNMP
Manager(s) that will configure and maintain status of the SP Switch Router Adapter card. The
community name to be used for communications with the SP SNMP Manager must be the
same community name that is specified in the Extension Node configuration data on the SP
control workstation where the SP SNMP Manager resides.
If no community name is specified on the SP control workstation, specify spenmgmt as the
community name for the SP SNMP Manager. The community name must allow read, write,
and trap capabilities. All community names used to communicate with managers other than the
SP SNMP Manager(s) should be restricted to read-only and trap capabilities. Traps should be
sent to the same UDP port on which the SP SNMP Manager is listening. This port will most
often be port number 162.
Using a UNIX editor, the administrator edits the configuration files required for each type of
media card. Configuration parameters for the SP Switch Router Adapter card could also be
entered in the
/etc/grdev1.conf file at this time if the card is not going to be configured via
SNMP. Save this file using the grwrite command.
The administrator now resets the SP Switch Router system to actually install the configuration
parameters. During a reset, system daemons restart and reread their files. The media cards also
boot, loading their software, configuration information, and the current route table.
Each time the SP Switch Router software boots, mib2d starts up. Unless the administrator has
already entered SP Switch Router Adapter configuration values in
/etc/grdev1.conf , file
parameters for SP Switch Router Adapter cards will all contain null values.
mib2d generates and sends a coldStart/warmStart trap message to all SNMP Managers
configured. It creates and initializes its MIB object instances. To support SET commands for
any instances of the SP Switch Router Adapter configuration objects, mib2d creates an
ibmSPDepNodeTable . The table contains an ibmSPDepNodeEntry MIB entry (there are 16
of these) for each available media card slot in various SP Switch Router models.
