Shutdown VLAN 1 and use some other VLAN interface for Management

Unanswered Question

Can anyone tell me what is the downside to shutting down VLAN 1 and using some other VLAN interface for the switches management? Does it make a difference is the other VLAN is configured as native on the connecting trunk?

I have this problem too.

Shutdown VLAN1 doesn't have disadvantage, this solution is prefered. So if you can please change your native vlan from vlan1 to other. Behind this scenario there are so many Security Attacks. You can read about these in the Web (spofing..)



Please rate me if I helped.

Thanks for your reply. I understand why it might be a good security posture to use something other than VLAN 1 for the management interface for the switch management. I would like to know if this will cause any significant problems it we do this.

This will NOT cause any problems. It is a good idea for security purposes to completely phase out VLAN 1. You can change the native VLAN on all your trunks to what you wish, also you can use a different VLAN for your management addresses. No problems.
