Port Loop Detection
Configuration
Port Loop Detection Overview
With port loop detection function, the switch can detect whether
there is a loop on the port. If there is a loop, the switch will take
measures. This can avoid broadcast storm.
On ZXR10 8900 series switch, port loop detection function can
be configured to detect loop on a port or all ports. By default,
the detection function is disabled. The switch supports detection
function based on
VLAN
, that is, the switch can detect loop in the
VLAN that owns the same
PVID
with that on the port, as well as in
the VLAN that users designate. On a port, it is up to detect loops
in 8 VLANs at the same time.
A port sends a Layer 2 multicast message every 15 seconds. If
there is a loop on a port, the multicast message will go back to the
port through which the message is sent.
Configuring Port Loop Detection
To configure port loop detection function, perform the following
steps.
Step Command
Function
1
ZXR10(config)#
loop-detect interface
<
port_name
>{
e
nable
|
disable
}
This configures port loop
detection function on one port
or multiple ports
2
ZXR10(config)#
loop-detect interface
<
port_name
>
vlan
<
vlan_id
>{
enable
|
disable
}
This configures port loop
detection function in a VLAN
or multiple VLANs that a port
belongs to
3
ZXR10(config)#
loop-detect portstate
{
block
|
normal
|
protect
}<
port_name
>
This configures the state of
loop port
