DGS-3610 Series Configuration Guide Chapter 48 TPP Configuration
48-3
Note
The topology protection function is suitable for the point-to-point link
network, and adjacent network devices must enable the topology
protection function. Besides, during the TPP configuration, you often need
to use CPU topology-limit to configure the threshold for CPU utilization
detection. When the CPU utilization exceeds the threshold, the system
generates the topology protection advertisement. We suggest a middle to
high value, such as 50–70, so that the TPP can judge the network
conditions more accurately. If the value is too small, the network topology
may not switch when it needs to switch due to TPP alarm. If the value is
too large, the system may be too busy to generate a TPP alarm, causing
the TPP invalid.
48.3.1 Configuring Global Topology
Protection
The global topology protection function is enabled by default. The no option of the command
disables the global topology protection.
The configuration commands are as follows:
Command
Function
DGS-3610> enable
Enter the privileged mode.
DGS-3610# config terminal
Enter the global configuration mode.
DGS-3610(config)# topology guard
Enable the global topology protection
DGS-3610(config)# end
Exit to the privileged mode.
DGS-3610# copy running-config
startup-config
Save the configuration.
The no topology guard command diables the global topology protection function on the
device.
48.3.2 Configuring the Topology Protection
on Port
The configuration commands are as follows:
Command
Function
DGS-3610> enable
Enter the privileged mode.
DGS-3610# config terminal
Enter the global configuration mode.
DGS-3610(config)# interface gi 0/1
Enter the interface configuration mode.
DGS-3610(config-if)# tp-guard port enable
Enable the port topology protection function.
