Recovery:
-
If one or more MPs in a
server
site have failed, the traffic will be distributed among the remaining MPs in
the
server
site. You can monitor MP
server
status from
.
-
The misconfiguration of STP routing may result in
too much traffic being distributed to the MP. You can monitor the ingress
traffic rate of each MP from
. Each
MP in the
server
site should be receiving approximately the same ingress transaction per second.
-
There may be an insufficient number of MPs
configured to handle the network traffic load. You can monitor the ingress
traffic rate of each MP from
. If
all MPs are in a congestion state, then the offered load to the
server
site is exceeding its capacity.
-
A software defect may exist resulting in PDU buffers
not being de-allocated to the pool when a PDU is successfully transmitted into
the network. This alarm should not normally occur when no other congestion
alarms are asserted. Examine the alarm log from
