Stp Enable - H3C S5120-SI Series Command Reference Manual

Use the stp edged-port disable command to configure the port(s) as a non-edge port or non-edge
ports.
Use the undo stp edged-port command to restore the default.
All ports are non-edge ports by default.
Note that:
Configured in Layer 2 Ethernet port view, the setting takes effect on the current port only;
configured in port group view, the setting takes effect on all ports in the port group.
Configured in Layer 2 aggregate port view, the setting takes effect only on the aggregate port;
configured on a member port in an aggregation group, the setting can take effect only after the port
leaves the aggregation group.
If a port directly connects to a user terminal rather than another device or a shared LAN segment,
this port is regarded as an edge port. When the network topology changes, an edge port will not
cause a temporary loop. Therefore, configuring a port as an edge port can enable the port to
transition to the forwarding state rapidly. We recommend that you configure a port directly
connecting to a user terminal as an edge port to enable it to transition to the forwarding state
rapidly.
Normally, configuration BPDUs from other devices will not be received by an edge port because it
does not connect to any other device. Before the BPDU guard function is enabled, if a port receives
a configuration BPDU, the port is working actually as a non-edge port even if you have configured
it as an edge port.
Among loop guard, root guard and edge port settings, only one function (whichever is configured
the earliest) can take effect on a port at the same time.
Related commands: stp loop-protection, stp root-protection.
