When you access VLAN Configuration mode, you specify the VLAN to create and configure initially. Later, you configure the VLAN from Global Configuration mode, or Interface Configuration mode.
SEFOS(config)# vlan VLAN-ID
where VLAN-ID is the number of the VLAN (1 - 4094).
For example, to create a VLAN with ID of 13 for initial configuration, type:
SEFOS(config)# vlan 13 SEFOS(config-vlan)#
You are now in VLAN Configuration mode for VLAN 13.
When you are finished, exit VLAN Configuration mode.
SEFOS(config-vlan)# exit SEFOS(config)#
