    Statistics If a station receives an AMP or SMP MAC frame with the ARI and FCI bits set to 0 without first receiving an intervening AMP frame it recognizes that its upstream station failed to set the ARI/FCI bits. The receiving station will increment an ARI/FCI set error counter, and end the ring poll process by not transmitting an SMP MAC frame.
  • Page 101 Statistics Lost frames are usually caused by a station entering or leaving the ring as the frame is circulating. Lost frames will cause the active monitor to initiate the ring purge process and issue a new token. Congest A congestion error occurs when a station recognizes a frame addressed to it, but is unable to copy the frame because it has no available buffer space.

    Ring Security Configuration Selecting a ring for which to set security; configuring the Allowed and Disallowed Station Lists; selecting ring security levels About Ring Security The Ring Security application allows you to control access to the Token Ring networks being managed by the TRMMIM by specifying an “Allowed List” of stations permitted to enter the ring, a “Disallowed List”...

    Ring Security Configuration manually (by entering the address of a disallowed station), or by moving an entry from the Allowed List. You can also restore a station from the Disallowed List to the Allowed List, if desired. Once Security has been configured and enabled, the TRMMIM acts as the Ring Security Monitor and provides security for the entire ring.

Note that if you are in the Warn mode, removing a station from the Allowed List will have little effect, because the station will remain on the ring and...

  • Page 109: Configuring Security

    Configuring Security Before configuring security, be sure that your network meets the requirements and conditions specified in your TRMMIM’s hardware Installation and User’s Guide. Your TRMMIM must also be properly configured to send traps to the appropriate network management station; this will ensure that traps generated by ring security arrive at the appropriate destination.

(Again, note that the TRMMIM’s Network components always have unique community names.) For devices which support the new global community names, you must make note of the automatic modifications that are made for network components, and use those specific community names when trying to access information stored in those components.
