SNMP activity during media card start up
After the SP Switch Router software boots, the media cards boot and load their boot
diagnostics. The SP Switch Router Adapter media card runs its diagnostics as a check for
hardware defects. If no failure is detected, the card’s run-time software is loaded. The screen
displays diagnostic and boot reports from all the media cards, interleaved as received.
If a hardware problem is found, the diagnostic forwards a
diagnostics. The SP Switch Router Adapter media card runs its diagnostics as a check for
hardware defects. If no failure is detected, the card’s run-time software is loaded. The screen
displays diagnostic and boot reports from all the media cards, interleaved as received.
If a hardware problem is found, the diagnostic forwards a
ConfigState
trap request to
mib2d. In turn, mib2d sends a
switchConfigState
trap message
(with
ConfigState=diagnosticFailed
) to the SP SNMP Manager. The SP Switch Router
Adapter card continues to execute its self-test software until the card is powered off (removed
from the chassis).
from the chassis).
Note:
The execution of diagnostics at boot time is an option. The default is for diagnostics to
run each time the SP Switch Router Adapter card boots.
After an SP Switch Router Adapter card successfully loads its run-time software, the card
requests its configuration parameters. After the run-time software verifies the parameters are
valid (not null), the card is ready to begin normal operation.
requests its configuration parameters. After the run-time software verifies the parameters are
valid (not null), the card is ready to begin normal operation.
If the configuration parameters contain null values, the card informs mib2d that the
configuration parameters have not been sent via a trap request message. mib2d sends the SP
SNMP Manager a
configuration parameters have not been sent via a trap request message. mib2d sends the SP
SNMP Manager a
switchConfigState
trap message
(
ConfigState=microcodeLoadFailed
) and also a
switchInfoNeeded
trap message.
The card remains in this state (5,
microcodeLoadFailed
) until it receives valid configuration
parameters, or until the card is reset. The card periodically requests configuration parameters
and sends trap request messages to mib2d.
and sends trap request messages to mib2d.
If the SP SNMP Manager is configured and operational, it responds to the mib2d trap
messages by sending SET commands to put the parameters in place. If the SP SNMP Manager
does not respond, there may be a configuration error that can be detected using the procedures
for diagnosing dependent node configuration problems in the PSSP Diagnosis Guide.

As a last resort, the network administrator can perform the following operations to install the
updated parameters on the SP Switch Router Adapter card:
updated parameters on the SP Switch Router Adapter card:
–
run the dev1config command
–
edit
/etc/grdev1.conf
as required
–
use grreset slot to reset the SP Switch Router Adapter media card
The SP Switch Router Adapter card can receive valid parameters either way. It does not begin
normal operation until it is brought on line with the SP system as the IP router interface.
