Resolving "show vlan" status


Due to some error which we come across in the pass, we decided to clear all settings and configuration in the 2950 Switch.

We basically used this command "clear config all" followed by

Cat2950# write erase
Erasing the nvram filesystem will remove all files! Continue? [confirm]y[OK]
Erase of nvram: complete
Cat2950#
Cat2950# reload

After which we Delete the VLAN information from Flash or NVRAM, and reload the switch.

Next we key in the command to create the vlan database again.

Cat2950(vlan)# vtp transparent
Setting device to VTP transparent mode
Cat2950(vlan)# vlan 10 name Internet
VLAN 10 added:
Name: Internet
Cat2950(vlan)# vlan 20 name Security
VLAN 20 added:
Name: Security
Cat2950(vlan)#exit
