native VLAN set to management VLAN

[tedauction]

Hello, in our organisation we use the management VLAN as the native VLAN.

I have been told the reason is:

"The reason of choose management VLAN as Native VLAN is for control manner which allow to run STP on native VLAN rather than default VLAN which might be various by vendor (Cisco is VLAN1, Juniper is VLAN default…etc)".

Does anyone understand this ? Is he saying that if you have different vendor switches, then STP might fail if you have different native VLANs on each switch ?

Thanks for any clarification.

the native VLAN discussion continues. I have difficulties interpreting your quote into context.

So my opinion is to not use the native VLAN at all if there is no need for it. I can see why you would not want to use the default VLAN 1 for security purposes, but to be honest, I would configure a dedicated VLAN for management. which is NOR the Native vlan, NOR the default VLAN, so make it any VLAN you want. 

So using different native VLans on different switches and addiing them to the same IP subnet could break communications, it depends on the design.  Have you got a design picture of the layout of your network?
