2.1.3 loopback-detection interface-list enable
Syntax
loopback-detection interface-list enable
undo loopback-detection interface-list enable
View
System view
Parameter
interface-list: Ethernet port list, in the form of interface-list = { interface-type
interface-number [ to interface-type interface-number ] } &<1-10>, where
interface-type is the port type, and interface-number is the port number.
Keyword to is used to specify a range of ports. The port number after to must be
equal to or greater than that before to.
&<1-10> means that you can specify up to 10 ports or port ranges.
Description
Use the loopback-detection interface-list enable command to enable the loopback
detection function on a range of ports.
Use the undo loopback-detection interface-list enable command to disable the
loopback detection function on a range of ports.
By default, the loopback detection function is enabled on ports if the device boots with
the default configuration file (config.def); if the device boots with null configuration, this
function is disabled.
At present, you can configure the loopback detection for ports in bulk on the S3100-EI
series (except the S3100-EPON-EI series) switches and the E126A switch only. These
switches are all shipped with a default configuration file (config.def).
Example
# Enable the loopback detection function on ports Ethernet 1/0/1 through Ethernet
1/0/4.
