NOTE

If you run the stp mcheck command in the system view, the MCheck operation is performed on all the

interfaces.

Step 5 Run:

stp transmit-limit packet-number

The maximum number of BPDUs sent by a port within each Hello time is set.

By default, the maximum number of BPDUs that a port sends within each Hello time is 147.

Step 6 (Optional) Run:

stp edged-port enable

The port is configured as an edge port.

If a device port is connected to a terminal, you can run this command to configure the port as

an edge port.

By default, a port is a non-edge port.

If the current port has been configured as an edge port, the port can still send BPDUs. This may

cause BPDUs to be sent to other networks, leading to network flapping. To prevent this problem,

run the stp bpdu-filter enable command to configure the edge port as a BPDU filter port and

disable the port from processing or sending BPDUs.

WARNING

After the stp bpdu-filter enable command is run on a port, the port no longer processes or sends

BPDUs. The port will not negotiate with the directly-connected port to establish an STP

connection.

Step 7 Run:

quit

Return to the system view.

Step 8 (Optional) Run:

error-down auto-recovery cause cause-item interval interval-value

The auto recovery function on an edge port is configured. This function enables a port in the

error-down state to automatically go Up after the specified delay.

There is no default value for the recovery time. Therefore, you must specify a delay when using

this command.

----End

Follow-up Procedure

When the topology of a spanning tree changes, the forwarding paths to associated VLANs are

changed. The ARP entries corresponding to those VLANs on the switching device need to be

updated. STP/RSTP processes ARP entries in either fast or normal mode.

l In fast mode, ARP entries to be updated are directly deleted.
