Table 11-8 OSI NSAP–to–DECnet Phase IV Address Conversion
DECnet: Poor Performance
Symptom: Performance in a DECnet network is slow or unreliable. Connections to hosts over one
or more routers are periodically inaccessible or drop unexpectedly.
Table 11-9 outlines the problems that might cause this symptom and describes solutions to those
problems.

Possible Problem Solution
DECnet traffic problem
Step 1 Use the show decnet traffic exec command and check the Received and
Forwarded fields in the output. In most cases, the values in these fields
should match.
Step 2 If the values do not match, check the Returned, Converted, Access Control
Failed, No Route, and Encapsulation Failed fields to see what is causing
the performance problem.
Step 3 If the problem cannot be isolated or solved, contact your technical support
representative for assistance.
