Chapter 48 TPP Configuration DGS-3610 Series Configuration Guide
Exit to the privileged mode.
The no tp-guard port enable command disables the topology protection on the port. This
command is suitable only on layer-2 switching ports and routing ports.It is inapplicable to AP
member ports.
The global topology protection is the global switch for the topology
protection. When it is enabled, the device detects the running parameters
of its own and monitors the running parameters of neighbor devices at the
same time. When exception appears locally, it sends exception
notification messages to the neighbor devices. When the port topology
protection function is enabled, it sends exception notification message to
neighbor devices if exception occurs locally.
48.4 Typical TPP Configuration
Examples
The figure below shows a dual-core networking topology:
Figure 48-2
As shown in the figure, A and B are L3 convergence devices, while C, D and E are L2
access devices.
The MSTP is enabled on A, B, C, D, and E, and VRRP is enabled on A and B. The topology
protection function enables the MSTP and VRRP to operate more reliable, avoiding
unnecessary vibration of the network topology.
