Troubleshooting Diameter Networks

Troubleshooting Diameter Network Configuration

Problem

Description

A misconfiguration of the network can prevent Diameter from functioning properly. Configuration options for the Diameter base protocol are simplifying the discovery of a misconfiguration.

Symptoms

The output of the show diameter peer command indicates a peer is in the no-activation state. In this case issue the show diameter peer map and show diameter network-element map commands to determine which network elements use the peer. The output of these commands can indicate why the peer is not activated. For example, all the associated network elements might have higher-priority peers in the open state.

The failed-to-forward counters are increasing in the output of the show diameter function statistics detail command. this can indicate that the routes to the peer are incorrectly configured. Check the network connectivity, then use the show diameter routes command to determine whether application traffic is being correctly forwarded.

Cause

Typical misconfigurations appear in the routes, peers, and network element configurations.

Solution

Use the appropriate statements to correct the misconfiguration.

Troubleshooting Diameter Network Connectivity

Problem

Description

In some circumstances, problems can arise with network connectivity to Diameter peers. The problem may originate with the peer or the peer host.

Symptoms

The output of the show diameter peer command indicates a peer is in the suspended, rejected, or bad-peer state.

Cause

The suspended state indicates that the peer is not responding or has some other malfunction, or the network path to the peer does not exist.

The rejected state indicates that the network connection has been rejected by the peer.

The bad-peer state indicates that the network connection has been rejected by the router on which the peer resides.

Solution

Determine how persistent the problem is by issuing the show diameter peer statistics peer-name brief command to check the connectivity statistics.
