Where “xxx.xxx.xxx.xxx” is the IP address of a computer on the
Ethernet network. Other Metasys Ethernet Routers and TCP/IP-
compatible computer systems send back a response. The “interval”
value is the number of clock cycles between pings and can range
from 1 to 32767. The default interval is 10 cycles. The pinging will
continue until stopped by any keystroke.
Failures are caused by cable problems, device driver configuration
problems, or computers being offline. The display indicates if the
ping was successful and the approximate response time. A normal
response time for Ethernet is 25 to 50 milliseconds.
If there are any Ethernet communications errors, they are noted. If
the Ethernet network is running properly, no errors are reported.
Ipstat Command
The program IPSTAT.EXE reports various useful statistics. To
launch IPSTAT, type the following at the DOS prompt:
IPSTAT
The resultant display reports the routing table, packet count, detected
errors and memory usage. If the Ethernet is operating properly, the
IPSTAT statistics should not report any errors.
Testnet Command
The Testnet command reads the configuration file (ROUTER.CFG)
and attempts to ping each router that is listed. The command format
is:
testnet
Testnet lists the communication status for each router. If Testnet can
talk to some routers but not others, the configuration files may
contain inaccurate information, such as a wrong address. To correct
bad addresses, reboot the system and access the configuration screen
during the boot process.
General Problem Prevention
1. Configure the Metasys Ethernet Router’s IP address, existing
LAN Router IP address, and subnet mask using information
from the customer’s network manager.
2. The Metasys ARCNET subnet addresses need to match the
router configuration file. Each ARCNET segment needs a
