Drag and drop the appropriate characteristics of Local VLANs and End-to-end VLANs
+ easy to maintain
+ users are based on geographic boundaries or their physical location
+ users are grouped into VLANs independent of a physical location
+ each VLAN has a common set of security and resource
+ users are assigned to the vlan regardless of their physical location within the campus n/w
+ Based on port security
End-to-end VLAN: VLAN members reside on different switches throughout the network. They are used when hosts are assigned to VLANs for policy reasons, rather than physical location.
Local VLAN: Hosts are assigned to VLANs based on their location, such as a floor in a building. This design is more scalable and easier to troubleshoot because the traffic flow is more deterministic. It enables more redundancy and minimizes failure domains.
(Reference: CCNP SWITCH 642-813 Quick Reference Guide)
Drag the steps on the left that should be part of a VLAN-based verification plan to the spaces on the right. Not all choices will be used.
+ Verify that there is inter-switch connectivity
+ Verify that switchports are properly pruned
+ Verify that creation of the virtual interface
+ Verify that the VLAN is assigned to the proper port
Wireless LWAPP Association and Discovery Process Drag & Drop. Note not all options are used
+ The IP Address is statically configured on the Lightweight AP
+ The Lightweight AP requests an IP address via DHCP
+ The Lightweight AP searches for a wireless LAN controller using LWAPP in Layer 2 Mode
+ The Lightweight AP sends a LWAPP Discovery request to the management IP address of the Wireless LAN Controller via Broadcast
+ The Wireless LAN Controller responds with a Discovery Response from the Manager IP address
+ The Lightweight AP chooses the AP Manager with the least number of associated access points and sends the join request
This sequence of events must occur in order for an LAP to register to a WLC:
1. The LAPs issue a DHCP discovery request to get an IP address, unless it has previously had a static IP address configured.
2. The LAP sends LWAPP discovery request messages to the WLCs.
3. Any WLC that receives the LWAPP discovery request responds with an LWAPP discovery response message.
4. From the LWAPP discovery responses that the LAP receives, the LAP selects a WLC to join.
5. The LAP then sends an LWAPP join request to the WLC and expects an LWAPP join response.
6. The WLC validates the LAP and then sends an LWAPP join response to the LAP.
7. The LAP validates the WLC, which completes the discovery and join process. The LWAPP join process includes mutual authentication and encryption key derivation, which is used to secure the join process and future LWAPP control messages.
8. The LAP registers with the controller.
