Reinitializing The Protocol For Mst; Verifying The Mst Configuration - Cisco Nexus 7000 Series Configuration Manual

Configuring MST Using Cisco NX-OS
This example shows how to configure the link type as a point-to-point link:
switch# config t
switch (config)# interface ethernet 1/4
switch(config-if)# spanning-tree link-type point-to-point
switch(config-if)# exit
switch(config)#

Reinitializing the Protocol for MST

An MST bridge can detect that a port is at the boundary of a region when it receives a legacy BPDU or an
MST BPDU that is associated with a different region. However, the STP protocol migration cannot determine
whether the legacy device, which is a device that runs only IEEE 802.1D, has been removed from the link
unless the legacy device is the designated switch. Enter this command to reinitialize the protocol negotiation
(force the renegotiation with neighboring devices) on the entire device or on specified interfaces.
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
SUMMARY STEPS
1. clear spanning-tree detected-protocol [interface interface [interface-num | port-channel]]
DETAILED STEPS
Command or Action
Step 1 clear spanning-tree detected-protocol [interface interface
[interface-num | port-channel]]
Example:
switch# clear spanning-tree detected-protocol
This example shows how to reinitialize MST on the Ethernet interface on slot 2, port 8:
switch# clear spanning-tree detected-protocol interface ethernet 2/8

Verifying the MST Configuration

To display MST configuration information, perform one of the following tasks:
Command
show running-config spanning-tree [all]
show spanning-tree mst configuration
show spanning-tree mst [detail]
