An end-to-end VLAN network has several characteristics:

    * VLAN membership for users is based on department or job function, regardless of where the users are located.
    * All users in a VLAN should have the same 80/20 traffic flow patterns.
    * VLAN membership for users should not change when they relocate within the campus.
    * Each VLAN has a common set of security requirements for all members.

Static VLANs:
    * All moves are controlled and managed.
    * There is robust VLAN management software to configure the ports.
    * The additional overhead required to maintain end-station MAC addresses and custom filtering tables is not acceptable.

Dynamic VLANs do not rely on ports assigned to a specific VLAN.

To configure VLANs on Cisco 2900 series switches, specific guidelines must be observed:

    * The maximum number of VLANs is switch dependent.
    * One of the factory-default VLANs is VLAN 1.
    * The default Ethernet VLAN is VLAN 1.
    * Cisco Discovery Protocol (CDP) and VLAN Trunking Protocol (VTP) advertisements are sent on VLAN 1 (VTP will be discussed in Module 9).
    * The IP address of the switch is in the VLAN 1 broadcast domain by default.
    * The switch must be in VTP server mode to create, add, or delete VLANs.
