Loop Detection Configuration
On this page, make the settings for loop detection that apply to all ports.
Figure 4-112 Configuration for loop detection
Note
Loops can only be detected between devices tha
t forward loop detection frames. Loops via
network components whose ports were blocked are not detected.
Enable or disable loop detection by clicking the check box.
If loop detection is disabled, the loop detection frames of other devices are forwarded.
By clicking the check box, specify for all ports whether or not loop detection frames are sent
out for all VLANs configured at the relevant ports.
If VLAN support is disabled, only loop detection frames without a VLAN tag are sent.
By entering a number, specify the number of received loop detection frames as of which a
loop is assumed.
If a port-specific setting was made, see below, "Variant" is displayed.
Remote Reaction (All Ports)
Specify how the device will react if a remote loop occurs. Select one of the two options from
the drop-down list:
● No reaction:
A loop has no effect on the port at which the loop occurs.
● Disable port:
The port at which the loop occurs is blocked.
If you have made a port-specific setting, see below, "Variant" is displayed.
