There are two ETHERNET protocols z/OS Communications Server
supports, 802.3 and standard
ethernet. An LCS device can be configured to
support one or both of these. Verify the ethernet type on the
LINK statement in the
TCPIP Profile matches the ethernet protocol in use for this
network.
Do the device types match?
- YES, the
device types match. Gather a CTRACE with options ARP, INTERNET,
and ICMP as well as a concurrent sniffer trace. Contact IBM
Software Support.
- NO, the
device types do not match. Change the LINK statement so that the
Ethernet type corresponds to that being used in the network.
