MSTP ELS Switch vs NON-ELS

Hi,

just two short questions:

1)

On an EX4300 with ELS-Firmeware, when I configure MSTP, I only can select the "whole" interface

set protocols mstp interface ge-0/0/27

When I configure MSTP on a non-ELS-Switch the subinterface is included

set protocols mstp interface ge-0/0/27.0

Is this normal behavior ?

2)

I think I found a incorrect statement in junipers documetation:

https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/show-spanning-tree-interface-spanning-trees-ex-series.html

It says:

Description

Display the configured or calculated interface-level spanning-tree protocol (can be either STP, RSTP, or MSTP) parameters. In brief mode, will not display interfaces that are administratively disabled or do not have a physical link.

But when I do a "show spanning-tree interface brief" also the Disabled und Disconneted Interfaces are listed.

Can someone else confirm that ?

Thanks to you all,

Christoph.
