Remove VLAN by CLI

[ColombianoTV]

good afternoon everyone
I have a WS-12-250-DC somehow configuring a VLAN on port 5 I lost web access through port 1 which is where the link enters, the strange thing about all this is that I have ping through port 1 and I have ssh access, I've tried looking at the help of the commands but I can't remove the vlan from port 5 and leave it as it comes... can someone help me with the commands to be able to delete that vlan

Thank you so much
Postada ... I have the link in the snow-covered hill of Santa Marta at 3100 meters high, access is difficult ... and if I can't do this I will have to go there to be able to fix it.
