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.
