Event “16”
ARP events
This event is logged by the Address Resolution Protocol (ARP) layer.
Entry 1 will always be zero.
Entry 3 of any ARP exception is a code uniquely identifying the software compo-
nent of ARP which reported the exception.
Entry 2 identifies the type of error.
2 “Local request to send was rejected; discarded request”
Internal error: An attempt by ARP to send an Ethernet frame with EDATreq()
failed. Possible Ethernet cable problems. Check that the LAN LED is ON or
Blinking.
3 “LAN system-software fault; resuming”
Internal error: An attempt by ARP to register itself with LLC as an Ethernet
user with EREGreq() failed.
4 “LAN system-software fault; resuming”
Internal error: An attempt by ARP to set a timer with STIMreq() failed.
5 “LAN data memor y exhausted- check parms; resuming”
Internal error: An attempt by ARP to allocate a buffer with BuffAlloc() failed.
6 ”Can’t locate remote node; discarded request”
This error is reported when ARP is unable to resolve an IP address to a MAC
address. Entry 4 is the number of attempts to resolve the IP address. Entries
5 & 6 are the unresolved IP address bytes displayed as two hexadecimal
words. For example, 3.0.0.1 would be shown as 0300H 0001H. This error may
indicate that the remote host is not operational on the network. Verify that
the local and remote nodes are both connected and that both applications are
specifying proper IP addresses.
7 “Bad remote application request, discarded request”
Received a response from more than one remote node when resolving an IP
address to a MAC address. This means two remote nodes have the same IP
address. Reconfigure the remote nodes to use unique IP addresses. Entries 5
& 6 are the offending IP address displayed as hexadecimal values.
9 “Bad remote application request, discarded request”
Received an ARP message from a remote node with this local node’s IP
address. This means there is an IP address conflict. Reconfigure the nodes to
use unique IP addresses.
