R21xx-HP FlexFabric 11900 Layer 2 LAN Switching Command Reference

122
Typically, configuration BPDUs from other devices cannot reach an edge port, because the edge port
does not connect to any other device. If a port receives a configuration BPDU when the BPDU guard
function is disabled, the port functions as a non-edge port, even if you configure it as an edge port.
On a port, the loop guard function, the root guard function, and the edge port setting are mutually
exclusive, and the one that is configured first takes effect.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate
interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.
Examples
# Configure Ten-GigabitEthernet 1/0/1 as an edge port.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] stp edged-port

Usage guidelines
When you enable the spanning tree feature, the device operates in STP, RSTP, or MSTP mode, depending
on the spanning tree mode setting.
When you enable the spanning tree feature, the device dynamically maintains the spanning tree status
of VLANs, based on received configuration BPDUs.
When you disable the spanning tree feature, the device stops maintaining the spanning tree status.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
