loop-detection

loop-detection
Sets the port type for the L2 loop detection functionality.
Syntax
To set or change information:
loop-detection {send-inact-port | send-port | uplink-port |
exception-port}
To delete information:
no loop-detection
Input mode
(config-if)
Parameters
{send-inact-port | send-port | uplink-port | exception-port}
send-inact-port
Sets a port as a detecting and blocking port. When an L2 loop detection frame
is sent and an L2 loop detection frame sent from the local switch is received,
log data is output and the port is blocked.
send-port
Sets a port as a detecting and sending port. When an L2 loop detection frame
is sent and an L2 loop detection frame sent from the local switch is received,
log data is output.
uplink-port
Sets a port as an uplink port. No L2 loop detection frames are sent. When an
L2 loop detection frame from the local switch is received, log data is output
from the frame source. If the port type of the frame source is detecting and
blocking port, the frame source is blocked.
exception-port
Sets a port as exempt from L2 loop detection. When an L2 loop detection
frame is received, no operation is performed.
1. Default value when this parameter is omitted:
This parameter cannot be omitted.
2. Range of values:
send-inact-port, send-port, uplink-port, exception-port
Default behavior
The port operates as a detecting port. If an L2 loop detection frame is not sent and an L2
loop detection frame sent from the local switch is detected, log data is output.
Impact on communication
None
When the change is applied
The change is applied immediately after setting values are changed.
