| Entry 2 identifies the type of error: |
1ªConfig'd gateway addr bad; can't talk off local netº
Configured default gateway address does not have same network ID as the Interface's IP address. During initialization, the netid part of the ªGateway Addressº (configured for this station) was found to be different from the netid part of the ªIP Addressº (configured for this station). Since the gateway must be on the same local network as this station, there is an error in configuration; this error must be corrected using the Logicmaster 90 Configurator or (if LM90 Config Mode is
How to determine the netid: When a Subnet Mask is configured, the station's netid is found by ANDing the Subnet Mask with the IP Address. Likewise, the gateway's netid is found by ANDing the Subnet Mask with the Gateway Address. When a Subnet Mask has not been configured (equals 0.0.0.0), the netid of the station and netid of the gateway are determined by the address class. For further information on IP addressing, see Appendix G of
2ªConfig'd gateway addr bad; can't talk off local netº
An outgoing IP datagram was addressed to a host that is not on the local network, and a default gateway is not defined. Entries 5 & 6 contain the IP address bytes of the unreachable destination displayed as two hexadecimal words. For example, 3.0.0.1 would be shown as 0300H 0001H.
The user should verify that the IP address of the remote host is correct. If correct, then the Gateway Address must be configured using the Logicmaster 90 Configurator or (if LM90 Config Mode is
3
Internal error: An IP request to send an ICMP Destination Unreachable message failed. Entry 4 indicates 3, the code for a Destination Unreachable ICMP message. Entries 5 & 6 contain the IP address bytes of the node to which the ICMP message would have been sent displayed as two hexadecimal words. For example, 3.0.0.1 would be shown as 0300H 0001H.
4
Internal error: An attempt to set a timer with STIMreq failed. Entry 4 contains the time intervalrequested.
5ªLocal request to send was rejected; discarded requestº
An attempt to send an Ethernet frame with EDATreq failed. PossibleEthernet cable problems. Check that the LAN LED is ON or Blinking. Entry 4 contains the value used for the Ethernet protocol type field.
