Terminate STP Domain

Hi all,

anyone knows the difference between the commands "undo stp enable" and "bpdu-drop any" on an L2 Interface which connects two switches? Platform is 5950. We want to separate STP Domains - and yes, we know about the drawbacks...

Thanks...

Hi,

Use undo stp enable to disable the spanning tree feature.

Default
The spanning tree feature is enabled on all ports.


Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view

Usage guidelines
When you enable the spanning tree feature, the device operates in STP, RSTP, PVST, 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.
If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
If this command is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
If this command is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.

Examples #

In MSTP mode, disable the spanning tree feature on Ten-GigabitEthernet 1/0/1.

 system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] undo stp enable

-----------------------------------------------------------------------------------------------------

Use bpdu-drop any to enable BPDU drop on a port.

Use undo bpdu-drop any to disable BPDU drop on a port.

Syntax

bpdu-drop any

undo bpdu-drop any

Default - BPDU drop is disabled on a port.

Views

Layer 2 Ethernet interface view

Examples

# Enable BPDU drop on port GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] bpdu-drop any
