identified, all ports which were previously turned off are turned back on. The failing port will be retried once at a pre-determined interval; if beaconing continues, the port will remain disabled.

Once ABRP is completed, the MicroMMAC-T generates traps to the remote management workstation which will pinpoint the problem’s cause, including:

•the beaconing adapter’s address

•its NAUN address

•beacon type

•port(s) and/or module(s) bypassed

•duration that the ring beaconed

You must then enable the faulty module or port before it can be used again. This prevents a user from rebooting a problem station which may bring the ring down.

To configure the beacon recovery and active monitor settings:

1.In the Network list in the upper right corner of the window, double-click on the Network 1 selection.

2.Click the mouse on the checkbox associated with the desired function. An X in the checkbox means that the selected function is activated.

3.If you are activating beacon recovery, be sure to configure the # of Ring Port Retries and the Retry Interval (in seconds) by clicking on the appropriate I-bar cursor and entering the desired value in the resulting window. Allowable values for # of Ring Port Retries are 0 - 100 and 999, where 0 will disable retries, 1-100 will set the number of retries, and 999 will retry the port indefinitely.

4.Click on OK.

To change the host error report timer delay:

1.In the Network list in the upper right corner of the window, double-click on the Network 1 selection.

2.Click on the I-bar cursor in the Host Error Report Timer Delay text box.

3.In the resulting window, type in the desired delay time between the recording and the reporting of an error.

4.Click on OK.

Enable Ring Poll Recovery

The Ring Poll Recovery option allows you to control the way each of the MicroMMAC-T management stations will respond when one or more stations stop participating in the ring polling process, which can prevent certain stations from inserting into the ring. When this option is enabled, the MicroMMAC-T will detect ring poll failures and remove the offending stations from the ring. Ring poll failure detection is based on the Neighbor Notification MAC frame (NNI) transmitted by the Active Monitor. Upon receipt of four consecutive NNI frames, the MicroMMAC-T will compare the information in the NNI frame with the ring’s
