TCP/IP problems with a Token-Ring network interface

Use these guidelines to resolve communication problems with your network interface.

If you cannot communicate with some of the machines on your network although the network interface has been initialized, the addresses correctly specified, and you have verified that the adapter card is good:

  • Check to see if the hosts with whom you cannot communicate are on a different ring. If they are, use the SMIT fast path smit chinet to check the Confine BROADCAST to Local Token-Ring field. Do not set to No in SMIT.
  • Check to see whether the token-ring adapter is configured to run at the correct ring speed. If it is configured incorrectly, use the SMIT to change the adapter ring speed attribute (see Adapter management and configuration). When TCP/IP is restarted, the token-ring adapter has the same ring speed as the rest of the network.
