Configuring TC-BPDU transmission restriction
![[CAUTION: ]](images/caution.png) | CAUTION: Enabling TC-BPDU transmission restriction on a port might cause the previous forwarding address table to fail to be updated when the topology changes. | |
The topology change to the user access network might cause the forwarding address changes to the core network. When the user access network topology is unstable, the user access network might affect the core network. To avoid this problem, you can enable TC-BPDU transmission restriction on a port. With this feature enabled, when the port receives a TC-BPDU, it does not forward the TC-BPDU to other ports.
Make this configuration on the port that connects to the user access network.
To configure TC-BPDU transmission restriction:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Layer 2 Ethernet interface or Layer 2 aggregate interface view. | interface interface-type interface-number | N/A |
3. Enable TC-BPDU transmission restriction. | stp tc-restriction | By default, TC-BPDU transmission restriction is disabled. |
