On a 2300 series switch, how are the interface "vlan participation exclude" and "vlan participation include" statements negated or removed?

[bruce_stahlin]

We've pushed configs, changing interfaces from phone ports to access and 802.1q trunk ports, yet certain statements remain. Here is an example after going from phone to access:

voice vlan X

voice vlan dscp 46

classofservice trust untrusted

description 'VLAN X'

switchport mode access

switchport access vlan X

vlan pvid XX

vlan participation exclude 1

vlan participation include XX,YY

vlan tagging XX

poe detection 4ptdot3af+legacy

We've been able to remove the following with prepending "no" statements:

no voice vlan

no voice vlan dscp

no vlan pvid XX

no vlan tagging

We've not found a way to remove:

vlan participation exclude 1

vlan participation include XX,YY

Any suggestions?

Hi BJ,

You can use something like "vlan participation auto <vlan id>" to revert this setting to default. From example, the following is from my test:

"

(s3-stack) #show running-config interface 1/0/3

!Current Configuration:

!

interface 1/0/3

classofservice trust untrusted

description 'Default settings for the trunk port'

switchport mode trunk

vlan participation include 200,300

poe detection 4ptdot3af+legacy

exit

(s3-stack) #configure 

(s3-stack) (Config)#interface 1/0/3

(s3-stack) (Interface 1/0/3)#vlan participation auto 200,300

(s3-stack) (Interface 1/0/3)#show running-config interface 1/0/3

!Current Configuration:

!

interface 1/0/3

classofservice trust untrusted

description 'Default settings for the trunk port'

switchport mode trunk

poe detection 4ptdot3af+legacy

exit

(s3-stack) (Interface 1/0/3)#

"

I've updated the case for this as well.

Of course, the case has been moved to our Tier 2 team, I've increased the priority on the case given how long it's been open, and I've messaged the Tier 2 manager to make sure the case gets more attention. Please don't hesitate to let me know if the case keeps stalling at this level and we'll get it up to our highest level of technicians for you.

Sam,

Can you help escalate case # 00271031 regarding this issue?

Thanks,

BJ

Thanks for your patience here, sorry for the long wait. The closest I've been able to get is to remove the VLAN from the database with:

(Enable) Vlan database 

No vlan #

However that would remove any other VLAN settings as well. I spoke with our senior engineers and they weren't able to find the command either but they did suggest opening a case on this question so they can dig in to it further, if you're interested. If we do open a case, we'd want a screen shot of the no command failing, tech data from the switch for background info, and we'd want to make sure we were using the latest firmware version available, then we can get the case to our experts for you.
