How to Delete vlan config on C4948-10g

Unanswered Question
Jul 2nd, 2012

Working on a C4948-10g switch. Trying to reset switch to factory settings. I have ran the Switch#>wr erase, command but the vlan's are still in the config. If you do a show vlan it still shows all the vlan text. I have tried the Switch#>delete vlan.dat, doesn't work. Tried Switch#>delete nvram:vlan.dat, doesn't work. Tried Switch#>erase startup-config, doesn't work. How can I get rid of the vlan's?                 

I have this problem too.

Hi Scott,

Just to confirm, command which you did is:

erase cat4000_flash:vlan.dat ??

If No, please run the above mention command.

That didn't work either. I should be able to do this command under Switch#erase cat4000_flash:vlan.dat

Any other ideas?

Switch#erase cat4000_flash:vlan.dat
             ^

Some how it deleted its self. I power cycled the unit and check the vlans config and they seem to be all gone. Thanks for your help.

Hello Scott,

Vlan.dat file only get removed from the swich when it gets reloaded, all the VLANs that were available on the switch are lost.

I hope that clear ot your query why after deleting the vlan.dat fle it was still showing unless it is rebooted.

Hope to Help !!
