FESX424 Switch-A> enable
No password has been assigned yet...
FESX424 Switch-A# configure terminal
FESX424 Switch-A(config)#
2. Enter the following command:
FESX424 Switch-A(config)# no vlan 5
FESX424 Switch-A(config)#
3. Enter the following commands to exit the CONFIG level and save the configuration to the system-config file on
flash memory:
FESX424 Switch-A(config)#
FESX424 Switch-A(config)# end
FESX424 Switch-A# write memory
FESX424 Switch-A#

FESX424 Switch-A(config-vlan-4)#
4. Enter the following commands to exit the VLAN CONFIG mode and save the configuration to the system-
config file on flash memory:
FESX424 Switch-A(config-vlan-4)#
FESX424 Switch-A(config-vlan-4)# end
FESX424 Switch-A# write memory
