Chapter 2 Alarm Troubleshooting
The IEEE 802.17b-based RPR RI Fail condition is raised by an ML card in primary or secondary mode.
If a card is in primary mode, a Gigabit Ethernet interface can cause an interconnect interface (IC) failure.
(The IC includes the Gigabit Ethernet interface and possibly a port channel interface.) In primary mode,
RPR-RI-FAIL can also be raised in response to a downed ring interface. In secondary mode, the only
possible cause of this condition is IC failure.
The alarm clears when the IEEE 802.17b-based RPR interface returns to Init modes and faults, if present,
are cleared. RPR-RI-FAIL is suppressed by the
Clear the RPR-RI-FAIL Condition
If the card is in primary mode, enter the following command at the CLI in privileged executive mode:
Step 1
router# show interface rpr-ieee 0
The RI information line displays the name of the monitored interfaces and says either "monitoring ring
Step 2
interface," or "monitoring interconnect interface."
Determine why the monitored interface is down. It can occur because the ring interface has been shut
Step 3
down using the "shutdown" CLI command, or because both SONET circuits are down or OOS.
If correcting the previous problem on a primary interface does not clear the condition, or if the condition
Step 4
is raised on a card is secondary mode, the IC failure root cause must be corrected. This can be due to a
fiber pull, having link protocol down, or shut down interfaces.

2.7.351 RPR-SD
The IEEE 802.17b-based RPR Signal Degrade condition indicates that a minor signal degradation has
occurred on an IEEE- RPR ring that, if not overridden, can deactivate the link.The RPR-SD condition is
reported if the SONET
RPR-SD condition clears when the SONET signal degrade clears.

It is suppressed by the following alarms:

SONET Logical Object: RPRIF
Link state is indicated in the "show interface rpr-ieee 0" output on the following line:
RPR-IEEE0 is up, line protocol is up
A shutdown is indicated if a node is in pass-through mode. The same command output indicates
whether or not this is the case:
MAC passthrough not set
