Removal of "spanning-tree portfast bpduguard default" on Layer 2 switc

[msanghera6]

I believe this was a valid command on the Cisco IOSv Layer 2 switches.

If I run this command on the following version, the option is no longer there.

inserthostname-here#show version
Cisco IOS Software, vios_l2 Software (vios_l2-ADVENTERPRISEK9-M), Experimental Version 15.2(20200924:215240) [sweickge-sep24-2020-l2iol-release 135]

What was the previous image that allowed for this command to be run?
Is there a plan to re-introduce this to DevNet later on?

PortFast and BPDU Guard can be applied 2-ways: globally and per port basis; Try both ways to see if command takes.  Also, try "?" (command context help ) to see what options u have. I don't have access to CML at this moment.

As you see in show version, your image (and all virtual lab images) are "Experimental Version" in nature. Not all "real switch" IOS features are supported in Virtual images; and even if they are, those features may not work as intended (bugs, limitations, etc).  As I recall previous version of IOSv Layer 2 image from CML has some other issues;  I would not use it.

Whoops

Looks like I was wrong
Just because I can see it after using "?" doesn't mean its not an option that can't be used
It actually says "spanning-tree portfast edge bpduguard default" in the running config

inserthostname-here(config)#spanning-tree portfast ?
edge Spanning tree portfast edge options
network Spanning tree portfast network options
normal Spanning tree portfast normal options

inserthostname-here#show run
