hub Bkp Link Table

1.3.6.1.4.1.11.2.14.2.8

A list of backup link configuration entries. For a given backup link, the hub will periodically send a test packet to the device at the end of the link. If there are no responses (the number is configurable), the hub will enable the backup port and disable the primary port. After the primary link is fixed, the user must turn the primary port on to resume normal operation. At any time, the management station can look at rptrPortAdminStatus for the backup port to determine if it is currently in use. The backup link algorithm enables and disables the backup port by modifying rptrPortAdminStatus for that port. After the backup port has been enabled by the backup link algorithm, if the primary port is subsequently enabled via the hub console port or by a set of rptrPortAdminStatus, the backup port will be turned off and the periodic test packets will begin again. When the backup link objects are set, the backup port will be turned off, the primary port will be turned on, and the periodic test packets will be sent. The time between test packets is configurable by setting hubBackupTestTime. The number of failures needed to switch to the backup link is configured by setting hubBackupConsecutiveFails. The backup link function can be turned off by setting hubBackupPort to 0. All five of the backup link objects must be set together in a single PDU except for the case of setting hubBackupPort to 0, in which case, the hubBackupPort can be set without setting the other objects. Currently, the size of the backup link table is one; future releases may provide the ability to monitor more than one backup link.
