6.6.1.6 Enabling STP/RSTP

Context
After STP/RSTP is enabled on a ring network, spanning tree calculation starts immediately on
the network. Configurations on a switching device, such as the device priority and port priority,
affect spanning tree calculation. Any change to the configurations may cause network flapping.
To ensure rapid, stable spanning tree calculation, perform basic configuration on the switching
device and its ports before enabling STP/RSTP.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
stp enable
STP/RSTP is enabled on the switching device.
By default, STP/RSTP is enabled on a industrial switch router.
----End
Follow-up Procedure
When the topology of a spanning tree changes, the forwarding paths for associated VLANs are
changed. Switching devices need to update the ARP entries corresponding to those VLANs.
Depending on how switching devices process ARP entries, STP/RSTP convergence mode can
be fast or normal.
l
l
Run the stp converge { fast | normal } command in the system view to configure the STP/RSTP
convergence mode.
By default, the normal STP/RSTP convergence mode is used.

NOTICE
In fast mode, ARP entries to be updated are directly deleted.
In normal mode, ARP entries to be updated are rapidly aged.
The remaining lifetime of ARP entries to be updated is set to 0 to immediately age the ARP
entries out. If the number of ARP aging probes is greater than 0, the switching device
performs aging probe for these ARP entries.
