FEP-CPF Communication

4.6.1 CPF Cannot Communicate with FEP

Error Description

Channels are constantly opened by FEP toward CPF, but CPF rejects them.

Causes

The FEP’s configuration for minimum channels toward CPF is greater than the corresponding

configuration of CPF for maximum channels. This causes the FEP to connect to CPF more

channels than CPF allows, so CPF rejects them.

Symptoms

The following WARN message appears in the CPF log:

“Channel {0} was rejected (for peer {1}) because the maximum allowed number of channels

({2}) was reached”

Instead of the following message:

{1} you should see a Diameter peer with the FEP’s name.

Resolution

Make sure that the following configuration parameters have the same values for all FEPs and

CPFs in the same site (default is 6 for all):

 Inside entry “ClientConnectionMaxSizes”: the value for

“ClientConnectionMaxSize” of protocol Diameter.

 Inside entry "ConnectionPoolSizeLowLimits": the value for

"ConnectionPoolSizeLowLimit" of protocol Diameter.

 Inside entry "ConnectionPoolSizes": the value for "ConnectionPoolSize" of

protocol Diameter.
