Table 4-10.Loop Protection Configuration Global Fields
Field Description
Interface The port or ports that are being configured.
Loop Protection Select Enabled or Disabled to administratively enable or disable this feature on the selected
interfaces. By default, this feature is disabled on all interfaces.
Note that loop protection can be enabled on static trunks, but cannot be enabled on trunks that
are dynamically formed through LACP.
Action Select the action to occur when a loop is detected on a port with loop protection enabled:
• Shutdown Port—The port will be shut down for the configured period. This is the default
selection.
• Shutdown Port and Log—The event will be logged and the port it shut down for the
configured period.
• Log Only—The event will be logged and the port remains operational.
Tx Mode When set to Enabled (the default), the port actively sends out loop protection PDUs to other
ports on which the loop protection feature is enabled. When set to Disabled, the port does not
send loop protection PDUs but can receive them from other ports. Tx Mode is enabled by default.
Click Apply to update the switch configuration. Your changes take effect immediately.
