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.
