Troubleshooting the Uplink Cards Installation
Investigate why the short path request was
not received.
Check other problems on the short span as
indicated on the neighbor node.
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.
Solution
None.
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.
