Configuring an Interface to Proactively Send Prestandard MSTP
Messages—CLI Version
By default, interfaces on a device running MST send prestandard, rather than standard, MSTP messages after
they receive a prestandard MSTP message from another interface. In Cisco NX-OS Release 4.0(2) and later
releases, you can configure the interface to proactively send prestandard MSTP messages. That is, the specified
interface would not have to wait to receive a prestandard MSTP message; the interface with this configuration
always sends prestandard MSTP messages.
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
