N umber of frames received should increase by 1 to 10 per
second, depending on traffic.
Number of messages received which contain user
data.
Number of messages with errors detected by the
CRC check. Should be less than 1 % of Frames received.
Normally the same as CRC errors. A difference
shows a serious line problem or a potential MUXserver
100 failure.
Total number of messages transmitted. Should
increase by 1 to 10 per second depending on traffic.
Number of messages transmitted which contain
user data.
Number of errors detected in errors transmitted.
A high count usually indicated a Transmit Clock problem.
No response was received by the MUXserver 100
from a DECmux II unit. Usually indicates a communica-
tions link failure.
NOTE
It is common for a small number of errors to occur. Large numbers
of errors (more than
10
per minute) usually indicate a communica-
tions line problem.
5.29 SHOW COUNTERS
Use this command to display counter information about messages transmitted
and received by the server on the Local Area Network.
The counters represent data accumulated since the counters were last set to
zero. The information under ETHERNET COUNTERS applies to low-level data
link transmissions between the MUXserver 100 and all nodes on the Ethernet.
The information under SERVER COUNTERS applies only to communications
between the server and the other nodes that implement the LAT architecture.
