Session Problem 9
An excessive number of circuit errors occur.
Solutions:
Do not ignore circuit errors. Use the following SNANCP command to check the
rate of circuit errors.
SNANCP> SHOW KNOWN CIRCUIT COUNTERS
Refer to the DECnet SNA Gateway-CT and ST Management book for a
description of each circuit counter.
Circuit errors are usually caused by an incorrectly configured system. Use the
appropriate SNANCP commands to show line, circuit, and PU characteristics.
Some errors that can occur because your system is incorrectly configured
follow:
•
A FRMR sent, I-frame too long error message is often caused by an
insufficient line buffer size.
•
A Reject received error message is often caused by setting the PU
segment size larger than the IBM MAXDATA parameter size.
•
Transmit and receive errors can be caused by incorrectly setting the circuit
duplex parameter to FULL when the IBM parameter is set to HALF
In addition, Frame retransmits error messages can occur because of problems
in the communications equipment or because of a noisy line. See Section 1.1,
Hardware Problem 5 for a description of how to solve these problems.
