There are about 3 basic configuration files on the 3550 switch:
mac-S-Ra~G#dir flash:
Directory of flash:/
2 -rwx 0 Jan 01 1970 00:01:24 env_vars
3 -rwx 342 Jan 01 1970 00:01:24 system_env_vars
4 -rwx 47 Jun 23 1993 07:54:48 private-config.text
5 -rwx 3928 Jun 23 1993 07:54:48 config.text
6 -rwx 1036 Mar 10 1993 23:22:21 vlan.dat
7 drwx 192 Mar 01 1993 00:03:12 c3550-i9q3l2-mz.121-11.EA1
15998976 bytes total (11616768 bytes free)
mac-S-Ra~G#
write erase will only take care of 'config.text'. The file will still exit
but its size will be zero, however the other two major files especially the
vlan.dat file containing all your vlan and vtp information.
To care care of all configurations:
#delete flash:config.text
#delete flash:vlan.dat
#delete flash:private-config.text
#reload
or you can do:
#delete flash:vlan.dat
#write erase
#reload
