Description
The amount of total A0
bandwidth on Ringlet1
reserved by all nodes on
the ring exceeds the
line rate
The amount of total A0
bandwidth on Ringlet0
reserved by all nodes on
the ring exceeds the
line rate
Too many stations have
been discovered in the
topology (maximum
number of ring stations
is 255)
All stations on the ring
now support jumbo
frame preference, MTU
for the ring has been
changed to JUMBO
MTU (9100 bytes).
Solution
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.
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.
Description
Protection cleared; Wait to Restore timer expired.
Solution
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.
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.
Execute the show rpr-ieee topology commandto
verify stations. Reduce the numer of stations in
the ring.
None. Remove jumbo preference on stations to
revert to REGULAR MTU (1500 bytes)
