After Changing Default VLAN ID, Can't Delete VLAN 1

On my SG200-26 switch (firmware version 1.4.2.4), I have changed the default VLAN from 1 to 20. I have removed every trace I can find of VLAN 1 in the switch's configuration, yet when I try to delete VLAN 1, I get this error:

"VLAN 1: VLAN can not be deleted because IP Interface or DHCP relay is defined on the VLAN.."

What else do I need to do to be able to delete VLAN 1?

VLAN 1 can never be deleted.

I had the pleasure (sarcasm) of working on a S500 (similar to S200) switch Friday.  It relies on VLAN1 for all of its "magic" and Smartport crap.  It only has L3 functionality for VLAN1.

I ended up removing it a replacing it with a 3650 and I was done in 10 minutes.

Me tooo like to join my best friend Leo on this.

VLAN 1 is by default and this cannot be deleted on any catalyst switch.

As you can see from the other answers, you can't delete Vlan1.  Having said that, I was wondering what you are trying to achieve?  Or what is your concern?
