Determining Whether a Remote TCP/IP Node Is
Reachable
To determine whether a remote node is reachable, run an Echo test by doing
the following:
1 Load PING
2 Specify the remote node address in the Host Name field.
3 Specify the number of seconds between each transmission in the Seconds
to Pause between pings field.
4 Specify the packet size to be transmitted in the IP Packet Size to send in
Bytes field.
5 Press Esc to begin transmitting.
If you receive an echo reply packet, the remote node is reachable.
Monitoring Error Counters
Error counters are monitored to make sure they are not increasing rapidly,
because a rapid increase indicates a problem. For information about
troubleshooting these problems, see “Troubleshooting” on page 93. You can
monitor error counters for TCP/IP interfaces in the following ways:
 Use MONITOR to view counters such as Checksum Errors, Send and
Receive Packet Errors, and interface-specific errors. To view these
counters, load MONITOR and select LAN/WAN information >
interface you want to view.
 Use TCPCON to view the following TCP/IP counters:
 IP Errors
 IP Address Errors
 Unknown Protocol Errors
 Local Errors
 Reassembly Failures Detected
 Fragmentation Failures Detected
To view these counters, load TCPCON and select Statistics > IP > More
IP Statistics.
