RUCKUS One enables a port to recover automatically from an error-disabled state by providing error disable recovery options at the switch level. Configuring this option eliminates the need for manual intervention each time a port becomes error-disabled.

1. From the navigation bar, select Wired > Switches > Switch List.
2. Click on a specific switch name.
   By default, the Overview tab and the Panel sub-tab are displayed.
3. Select the Ports sub-tab.

   

4. Click Error Disable Recovery to configure automatic recovery options for one or more error conditions.
   The Error Disable Recovery sidebar is displayed.

   

5. For Timeout, configure the timeout interval for ports in the error-disabled state, after which the ports are re-enabled automatically. Valid values are from 10 through 65535 seconds; the default value is 300 seconds.
6. For Error Disable Recovery, select one or more error disable recovery options from the drop-down list.
   • Select All: Enables auto-recovery from all causes.
   • BPDU Guard: Enables auto-recovery from a Bridge Protocol Data Unit (BPDU) Guard error condition, which protects against BPDU attacks by disabling the port if a BPDU is received.
     Note: If you enable STP BPDU Guard at the port level, the system will automatically enable BPDU Guard in the Error Disable Recovery settings at the switch level.
   • Loop Detect: Enables auto-recovery from a loop detection error condition, which prevents network loops by disabling the port if a loop is detected.
   • Packet InError: Enables auto-recovery from a packet inError error condition, which disables the port if it receives packets with errors.
   • LOAM Remote Critical Event: Enables auto-recovery from a Link OAM (LOAM) Remote Critical Event error condition, which is a critical error (such as a switch fan failure or a switch over-temperature condition) affecting the Ethernet in the First Mile (EFM)-OAM interface, as detected by the remote peer device.
   • PVST Plus Protect: Enables auto-recovery from a Per-VLAN Spanning Tree (PVST) Plus Protect error condition, which protects against misconfigurations in PVST.
   • BPDU Tunnel Threshold: Enables auto-recovery from a BPDU Tunnel Threshold error condition, which protects against excessive BPDU tunneling.
   • LAG Operational Speed Mismatch: Enables auto-recovery from a Link Aggregation Group (LAG) Operational Speed Mismatch error condition, which occurs when there is a speed mismatch in the aggregated links.
7. Click Apply.
