The Loop Protection Configuration page allows the user to inspect the current Loop Protection configurations, and possibly change them.

Figure 4-60. Loop Protection Configuration

The Loop Protection Configuration page has the following parameters:

  • General Settings
    • Enable Loop Protection: Controls whether loop protections are enabled (as a whole).
    • Transmission Time: The interval between each loop protection PDU sent on each port. Valid values are 1s–10s. The default value is 5s.
    • Shutdown Time: The period (in seconds) for which a port is kept disabled if a loop is detected (and the port action shuts down the port). Valid values are 0 to 604800 seconds (7 days). A value of zero keeps a port disabled (until the next device restart). The default value is 180s.
  • Port Configuration
    • Port: The switch port number of the port
    • Enable: Controls whether loop protection is enabled on this switch port or not
    • Action: Configures the action performed when a loop is detected on a port. Following are the valid values:
      • Shutdown Port
      • Shutdown Port and Log
      • Log Only
    • Tx Mode: Controls whether the port is actively generating loop protection PDU's, or whether it is just passively looking for looped PDUs.
