Troubleshooting ISO CLNS
This section presents protocol-related troubleshooting information for ISO CLNS protocol
connectivity and performance problems. It describes specific ISO CLNS symptoms, the problems
that are likely to cause each symptom, and the solutions to those problems.
Note Discussions of host configuration problems in this chapter assume that the host is a UNIX
system. Equivalent actions might also be applicable to non-UNIX hosts, but the discussions do not
specifically address non-UNIX end-station problems.
The following sections cover the most common network issues in ISO CLNS networks:
• ISO CLNS: Host Cannot Access Hosts on Local or Remote Network
• ISO CLNS: Host Cannot Access Hosts in Same Area
• ISO CLNS: Host Cannot Access Hosts in Different Area
• ISO CLNS: Connections Fail Using Certain Protocols
• ISO CLNS: Users Cannot Make Connections over Parallel Path
• ISO CLNS: Redistribution Causes Routing Problems
• ISO CLNS: Poor Performance
ISO CLNS: Host Cannot Access Hosts on Local or Remote Network
Symptom: Hosts cannot communicate with other hosts. Hosts might be located on the local or a
remote network. Connections to some hosts on a network might be possible, whereas connections to
other hosts on the same network fail.
