CONFIGURING LOOP PROTECTION
Use the Loop Protection page to detect general loopback conditions caused
by hardware problems or faulty protocol settings. When enabled, a control
frame is transmitted on the participating ports, and the switch monitors
inbound traffic to see if the frame is looped back.
PATH
Advanced Configuration, Loop Protection
USAGE GUIDELINES
◆ The default settings for the control frame transmit interval and recover
time may be adjusted to improve performance for your specific
environment. The response mode may also need to be changed once
you determine what kind of packets are being looped back.
◆ Loopback detection must be enabled both globally and on an interface
for loopback detection to take effect.
PARAMETERS
These parameters are displayed:
Global Configuration
◆ Enable Loop Protection – Enables loopback detection globally on the
switch. (Default: Disabled)
Loopback detection must be enabled globally for the switch and
enabled for a specific port for this function to take effect.
◆ Transmission Time – The transmission interval for loopback detection
control frames. (Range: 1-10 seconds)
◆ Shutdown Time – The interval to wait before the switch automatically
releases an interface from shutdown state. (Range: 1-604,800
seconds, or 0 to disable automatic recovery)
If the recovery time is set to zero, any ports placed in shutdown state
will remain in that state until the switch is reset.
