set spantree lp
8-42 Spanning Tree Configuration
set spantree lp
Use this command to enable or disable the Loop Protect feature per port and optionally, per SID.
The Loop Protect feature is disabled by default. See “Loop Protect” on page 2. for more
information.
Syntax
set spantree lp port-string {enable | disable} [sid sid]
Parameters
Defaults
If no SID is specified, SID 0 is assumed.
Mode
Switch command, read‐write.
Usage
Loop Protect takes precedence over per port STP enable/disable (portAdmin). Normally
portAdmin disabled would cause a port to go immediately to forwarding. If Loop Protect is
enabled, that port should go to listening and remain there.
Example
This example shows how to enable Loop Protect on fe.2.3:
D2(su)->set spantree lp fe .1.11 enable
show spantree lp
Use this command to display the Loop Protect status per port and/or per SID.
Syntax
show spantree lp [port port-string] [sid sid]
Parameters
port‐string Specifies port(s) on which to enable or disable the Loop Protect feature.
enable | disable Enables or disables the feature on the specified port.
sid sid (Optional) Enables or disables the feature for specific Spanning Tree(s).
Valid values are 0 ‐ 4094. If not specified, SID 0 is assumed.
Note: The Loop Protect enable/disable settings for an MSTI port should match those for the CIST
port.
port‐string (Optional) Specifies port(s) for which to display the Loop Protect
feature status.
sid sid (Optional) Specifies the specific Spanning Tree(s) for which to display
the Loop Protect feature status. Valid values are 0 ‐ 4094. If not
specified, SID 0 is assumed.
