Primary Link Port: This object identifies the port number of the primary link for a given redundant link pair.
Secondary Link Group: This object identifies the hub ID of the secondary link for a given redundant link pair.
Secondary Link Port: This object identifies the port number of the secondary link for a given redundant link pair.
Active Link: This object indicates the current status for a given redundant link pair.
•Primary: The port is currently the active primary link.
•Secondary: The port is currently the secondary port.
•Both fail: Both the primary and the secondary failed.
Link Switch Over Notify: If the link status of the active link is down for more than five seconds then the active link failure is detected and “port switch over” is performed and a trap is sent to the trap receivers.
•Enable: A trap is sent to the trap receivers if a switch over occurs.
•Disable: No trap is sent to the trap receivers if a switch over occurs.
Status: You can enable, disable or suspend the operation of specific redundant link pairs.
•Enable: The redundant link pair is in the normal operation mode.The primary port is active and the secondary port is disabled.
•Disable: If you disable the active port, the status of this link pair is changed to the suspend state and indicates that the active port has been disabled and the redundant link function is temporarily suspended. If you enable the active port later on, the status of this redundant link pair is changed to enabled.
NOTE: Setting the redundant link to disable does not cause the ports to be switched over.
