Port Loop Detection Example

As shown in Figure
telnet into the switch A. Port gei_1/1 is in Vlan1 and Vlan2. Enable
loopback detection in port gei_1/1. Loopback detection is done in
Vlan1 and Vlan2 at the same time. Switch A is connected to Switch
B with gei_1/1 port. Switch B shuts spanning-tree protocol and
loop two ports with one network line. The two ports in loop and
the port which connect to switch are in the same Vlans as gei_1/1.

Function
This configures the loopback
detection of Vlan in one port.
This configures the loopback
detection port interface.
When a switch detects
a loopback of one port,
switch deal with it
according to parameter
protect-interface. When
parameter protect-interface
is enable, switch sets a
alarm it has detected a
loopback but there will be
no operation. When the
parameter protect-interface
is disable, the switch will
shutdown the port. After
enabling loopback detection,
the default parameter
protect-interface is disable.
This configures the
reopen-time when the port
was shut down as a result of
loopback detection.
This enables the loopback
detection function.
This displays detail of port
which enables loopback
detection.
This displays the port which
enables loopback detection
protection.
This displays the reopen-time
when one port has been
shutdown in result of loopback
detection.
