RPR-IEEE1/1 protected on
span EAST (span WEST
Long Request Manual
Switch)
Neighbor node Manual
Switch initiated by user;
Node wrap to protect
failed span; Secondary
problem on the short path
Investigate why the short path request was
not received.
Check other problems on the short span as
indicated on the neighbor node.
RPR-IEEE1/1 protected on
span EAST (span WEST
Long Request Signal Fail)
Neighbor node protected
due to signal fail
Investigate signal fail on neighbor node.
Investigate why the short path request was
not received.
Check other problems on the short span as
indicated on the neighbor node.
RPR-IEEE1/1 protected on
span EAST (span WEST
Long Request Signal
Degrade)
Neighbor node protected
due to signal degrade
Investigate signal degrade on neighbor
node. Investigate why short path request
was not received.
Check other problems on the short span as
indicated on the neighbor node.

Table 5-11 Other IEEE 802.17 RPR Alarm Messages
Alarm Description Solution
RPR-IEEE1/1 Ringlet1
reserved A0 bandwidth
has exceeded line rate
The amount of total A0
bandwidth on Ringlet1
reserved by all nodes on the
ring exceeds the line rate
Check current A0 allocations on each
station using the show rpr-ieee rate-limit
command.
Change the A0 allocation on the ring by
using the rpr-ieee tx-traffic reserved CLI
command.
RPR-IEEE1/1 Ringtlet0
reserved A0 bandwidth
has exceeded line rate
The amount of total A0
bandwidth on Ringlet0
reserved by all nodes on the
ring exceeds the line rate
Check current A0 allocation on each station
using the show rpr-ieee rate-limit
command.
Change the A0 allocation on the ring by
using the rpr-ieee tx-traffic reserved CLI
command.
RPR-IEEE1/1 MAX
Stations Exceeded
Too many stations have
been discovered in the
topology (maximum
number of ring stations is
255)
Execute the show rpr-ieee topology
commandto verify stations. Reduce the
numer of stations in the ring.
