1.1 Troubleshoot the network at Headquarters

so that for the connections between the 3650s and the 4500s, corporate wireless user traffic for VLANs 101 and 102 only, use G1/0/20 on the 3650s as the primary forwarding link. G1/0/21 on 3650-1 and 3650-2 must be used exclusively as a backup connection. Notes:

  • Use an STP method that prioritizes how the local switches (that is, the 3650s) elect the root port.
  • Configuration should be applied to the G1/0/21 interfaces only.

Solution:

3650-1 & 3650-2

3650-1 & 3650-2

2.1 Bridging

The bridge link between A3700-BR1 and A3700-BR2 does not come up as planned. Troubleshoot and fix the issues to enable the bridge link to be established while maintaining these requirements:

  •   The link must use the SSID BridgeYY, broadcast by A3700-BR1 and using the first available channel in UNII-3.
  •   This is an infrastructure SSID bridge link between A3700-BR1 (which is acting as the Root AP), and potential WGBs (only A3700-BR2 for now). Use RSN for Layer 2 security.
  •   A3700-BR1 must allow A3700-BR2 to authenticate against its internal RADIUS server using EAP-FAST only. Create a “BR2-user” user that belongs to the group EFAST-GROUP in order to achieve this, and set its password to “cisco”.
  •   Make sure that multicast/broadcast packets to the WGB are acknowledged.
  •   WGBs must handle multicast/broadcast packets in the most efficient possible way.
 

Solution:

Yellow is config. Other is preconfig.

1.1 Layer2 troubleshooting - HQ VLANs & VTP Server/Client

At HQ-Alpha, any unnecessary broadcast VLAN traffic must be stopped from reaching 3650-1.

The setup of HQ-Beta replicates that of HQ-Alpha, that is the 4500 is the VTP server and the 3650 is the VTP client. Your colleague reports that although he has created a new VLAN "Test-VLAN" on 4500-2, this new VLAN broadcast traffic is not reaching 3650-2. You must ensure that the new VLAN traffic always reaches 3650-2.

4500-1 (server) and 3650-1 (client) is one server/client relationship domain name is HQA

4500-2 (server) and 3650-2 (client) is another server/client relationship

ensure that no unwanted broadcast is not forwarded to 3650-1 (enable vtp pruning on 4500-1)

HQ B replicates HQ A in that 4500s are servers and 3650s are clients, Test vlan (997) is not propagated to 3650-2 from 4500-2

For this VTP domain on 4500-2 is HQB but on 3650-2 is HQA.  Also 3650-2 is a server. Configure 3650-2 as client and correct the domain on 3650-2 to HQB. Also VTP password

on 4500-1, 3650-1 and 4500-2 is CCIEW but on 3650-2 it is something else. Correct the VTP password on 3650-2 to CCIW.

In the exam even after doing this the VLANs weren't propogating to 3650-2 as the config revision number was 0. Switch the VTP mode to transparent and then back to client.


On 4500-2:

vtp domain HQB

vtp pruning

vtp mode server

vtp password CCIEW


On 3650-2:

MAC flapping on the core switch Concept ?

Your customer reports high CPU utilization on its core switch. ?The log messages on the switch show a lot of MAC flapping messages, which indicate the root cause for this high CPU utilization. ?The MAC addresses in the logs all belong to wireless clients. ?The clients are moving between APs that belong to different WLCs and that are part of one mobility group. Symptoms During their investigation of the high CPU utilization on the core switch, the LAN/switch team confirmed that the high CPU is being caused by MAC flapping, and that all of the MAC addresses that appear to be flapping on the logs are MAC addresses of wireless clients.

Your expertise is needed to diagnose a problem where MAC flapping messages are causing high CPU utilization on the core switch. It has been determined that all of these MAC addresses belong to wireless clients. You have been provided with these documents and resources: ?email thread between the customer and first-line support ?topology diagram ?device configurations/show commands ?debugs

Q1. Which two actions resolve this problem permanently? (Choose two.)

A. Configure the two WLCs for high availability active/active without changing the WLC registration of the AP.
B. Change the WLAN settings to local switching/central authentication.
C. Configure both WLANs to use different subnets on each WLC.
D. Configure the WLCs for EtherChannel (LAG) to ensure that the correct load-balancing mehod is being used on the core switches.
E. MAC flapping is normal behaviour for this type of setup/topology. The MAC flapping messages cannot be avoided.
F. Disable the MAC flapping notification messages on the core switch.
G. Join all the APs to the same WLC.
H. This behavior is related to a bug. You must upgrade the switch to a newer code to avoid this kind of cosmetic error.
A--
C. Configure both WLANs to use different subnets on each WLC.
G. Join all the APs to the same WLC.

Q2: For this scenario, how does the CAM table of the core switch learn the wireless clients MAC addresses?
Q3: Both WLCs are running code 8.3. Assume that all WLANs are indentically configured on both WLCs. Based on the WLAN security type, which WLAN configured in the Cisco 5508-1 WLC does not support mobility roaming?

Wireless guest user is unable to gain access to the guest network. Concept ?
Q2. Which root cause of the problem is true?
Q3. What two options do you suggest to stop this problem from happening?

Q4. Which packet # in the sniffer trace shows that there is a problem?

Ticket#3:Download Now

The WLC cannot be managed via Cisco Prime Infrastructure Concept ?

We are trying to integrate MSE, PI, and a WLC so that we can track the wireless clients. ?We are at the early stages of the implementation, and we cannot get Cisco Prime to manage the WLC. ?This very same WLC had been implementation, and we cannot get Cisco Prime to manage the WLC. ?This very same WLC had been added before, but now, for some reason, it is no longer manageable by Cisco Prime. ?A CPU ACL is blocking SNMP communication between the two devices.

Q1. Which root cause of this problem is true?

Q2. Based on the outputs, which two statements are true? (Choose two.)

 

Q3. Which output helps the most to understand the problems?
