1.10 STP Maintenance Configuration

1.10.1 Introduction
In a large-scale network with MSTP enabled, there may be many MSTP instances, and
so the status of a port may change frequently. In this case, maintenance personnel may
expect that log/trap information is output to the log host when particular ports fail, so
that they can check the status changes of those ports through alarm information.

1.10.2 Enabling Log/Trap Output for Ports of MSTP Instance

Follow these steps to enable log/trap output for ports of MSTP instance:
To do...
Enter system view
Enable log/trap
output for the
ports of a
specified instance
Enable log/trap
output for the
ports of all
instances
1.10.3 Configuration Example
# Enable log/trap output for the ports of instance 1.
<Sysname> system-view
[Sysname] stp instance 1 portlog
# Enable log/trap output for the ports of all instances.
<Sysname> system-view
[Sysname] stp portlog all
1.11 Enabling Trap Messages Conforming to 802.1d
Standard
A switch sends trap messages conforming to 802.1d standard to the network
management device in the following two cases:
The switch becomes the root bridge of an instance.
Network topology changes are detected.
I. Configuration procedure
Follow these steps to enable trap messages conforming to 802.1d standard:
Use the command...
system-view
stp [ instance
instance-id ] portlog
stp portlog all
