Skills Assessment

Objectives Part 1: Build the physical network topology. Part 2: Load the functioning base device config file from flash to the running config for each device and test network connectivity. Part 3: Copy the Skills Assessment error file from the TFTP server into flash for each device. Part 4: Erase the startup config and copy the Skills Assessment error file from flash to the running config for each device. Part 5: Troubleshoot the errors introduced.

Exam Overview This Skills Assessment is the final practical exam for the course CCNPv7 TSHOOT. The exam is divided into five parts, which must be completed sequentially. In Part 1, you build the physical network. In Part 2, you load functioning config files on all devices and verify access to the TFTP server. In Part 3, you copy the error files from the TFTP server to flash for the respective devices and in Part 4 you erase the base configs and load the error configs. You troubleshoot and resolve the errors in Part 5. This exam combines the process of course setup with the actual troubleshooting process. In addition to correcting configurations and restoring basic connectivity, network protocols such as SSH and NTP must also be verified. Note: Refer to the Base Topology and Overlay Topology diagrams and accompanying tables at the beginning of this document when building the network or troubleshooting issues. All necessary data is provided to methodically troubleshoot the network issues.

This lab uses Cisco ISR G2 routers running Cisco IOS 15.4(3) images with IP Base and Security packages enabled, and Cisco Catalyst 3560 and 2960 switches running Cisco IOS 15.0(2) IP Services and LAN Base images, respectively. The 3560 and 2960 switches are configured with the SDM templates dual-ipv4-andipv6 routing and lanbase-routing, respectively. Depending on the router or switch model and Cisco IOS Software version, the commands available and output produced might vary from what is shown in this lab.

Skills Assessment

Part 1: Build the Physical Network Connect all devices as shown in the Base Topology and Overlay Topology. You must use the interfaces specified in the Device Interfaces and Links table at the beginning of the Skills Assessment.

Part 2: Load the Skills Assessment Base Device Configuration Files from Flash Use the following procedure to copy the functional base Skills Assessment configuration (non-error) file from flash to the running config for each device and test network connectivity.

Step 1: Verify the existence and location of the Skills Assessment base configuration files. The base configuration files should be present in flash under the tshoot directory for a given device. Use the show flash command to verify the presence of this directory. You can also verify the contents of the directory using the cd and dir commands. If the directory and files are not present, contact your administrator. ALS1# show flash Directory of flash:/ 9 3 5 6 7 8 10

SA-ALS1-BASE-Cfg.txt

Step 2: Erase the startup config from NVRAM. Step 3: Delete the VLAN database from flash (switches only). Step 4: Reload the device, but do not save the system configuration if prompted. Step 5: When the device restarts, do not enter the initial configuration dialog, but terminate autoinstall if prompted. Step 6: Copy the Skills Assessment device configuration file from flash to the running config. The format of these files is SA-xxx-BASE-Cfg.txt, where xxx is the name of the device. For example: Switch# copy flash:/tshoot/SA-ALS1-BASE-Cfg.txt running-config Destination filename [running-config]? Enter Note: Although it is possible to copy the file to the startup config and reload the device, the RSA keys for SSH cannot be generated from the startup config.

CCNPv7 TSHOOT

Skills Assessment

Step 7: Copy the running config to the startup config. Even if you see an Autosave message indicating that the running configuration has been saved to NVRAM, copy the running config to the startup config manually. Note: If the device is rebooted at this point, you can log in remotely with the username cisco and the password cisco. To access privileged EXEC mode, use the enable password cisco. Note: Although it is not considered security best practice, the exec-timeout for the console line is set to 0 (no time out) to facilitate performance of this Skills Assessment.

Step 8: Repeat steps 2 through 7 for all other devices in the network. Step 9: Set the time on the NTP server R2. Set the correct time on the NTP server R2 using the clock set command.

Step 10: Configure the PCs. a. Configure SRV1 with the static IP address 10.1.100.1/24 and the default gateway 10.1.100.254. b. Start the syslog server and TFTP server on SRV1. c.

Configure PC-B and PC-C as DHCP clients.

d. Release and renew the DHCP leases on PC-B and PC-C. e. Test connectivity from each PC. Troubleshoot if necessary.

Part 3: Copy the Skills Assessment Error Files from the TFTP Server Step 1: Verify connectivity with the TFTP server SRV1. You must be able to access the TFTP server on SRV1 from each network device to copy the error files. From each device (ALS1, DLS1, DLS2, R1, R2, and R3) ping SRV1 at 10.1.100.1. Note: If the pings are not successful, verify physical network cabling and connections and verify that the Skills Assessment base config file is loaded as the running config in each device. You can exit from the user EXEC mode prompt to see the MOTD login banner, which indicates the file currently loaded. For example: *** Switch ALS1 Skills Assessment BASE Config *** If you still cannot access SRV1 from a particular device, contact your administrator.

Step 2: Verify the TFTP server configuration. Verify that the TFTP server on SRV1 is running and that the error files are present in the default TFTP directory. The format of these files is SA-xxx-Error-Cfg.txt, where xxx is the name of the device.

Step 3: Copy the TFTP server Skills Assessment error file to flash. Copy the appropriate Skills Assessment error file from the TFTP server into the flash:/tshoot directory for each device.

Step 4: Release and renew the DHCP leases on PC-B and PC-C. Verify that R2 has received DHCPv4 and SLAAC addresses.

CCNPv7 TSHOOT

Skills Assessment

Part 4: Load the Skills Assessment Error Files from Flash to the Running Config For each device, follow the procedure similar to what is described in Part 2. An abbreviated version is provided below.

Step 1: Erase the startup config. Step 2: Delete vlan.dat (switches only). Step 3: On the switches, configure the SDM template: dual-ipv4-and-ipv6 routing on 3560 switches and lanbase-routing on 2960 switches. Step 4: Issue the reload command and respond as indicated in Part 2. Step 5: Copy the Skills Assessment error file from flash to the running config. Step 6: Copy the running config to the startup config.

Part 5: Troubleshoot the Errors Introduced The Skills Assessment error files introduce various problems, including issues related to MST, VTPv3, NTP, SSH, VLANs, VLAN trunks, EtherChannel, DHCPv4, DHCPv6, SLAAC, HSRP with object tracking, RIPv2, RIPng, Named EIGRP, OSPFv2, OSPFv3 for IPv6 with and without address families, MP-BGP, redistribution, route authentication, route filtering, securing switched networks, and local AAA. Hint: Two configuration errors are introduced in each device for a total of 12 errors.

Step 1: Perform connectivity tests. Use connectivity testing tools such as ping, traceroute, tracert (PC), and CDP to determine the extent of connectivity loss. Use the following table to record the results of the connectivity tests. Be sure to ping from each PC to enough network device interfaces, and from the network devices to enough network device interfaces, to determine an appropriate troubleshooting strategy. Note: You can use the Ping Test table in Step 3 as a starting point. Or you can use your own version of the Tcl scripts below (adding addresses from the IP Address Table above and starting in Privileged EXEC mode), to test reachability from a Cisco device to any destination: tclsh foreach address { 192.168.3.1 192.168.1.1 } { ping $address } tclsh foreach address { 2001:db8:feed:10::2 2001:db8:cafe:203::1 } { ping $address }

Step 2: Document, resolve, and verify the issues discovered. Using the tools available, such as show and debug commands, discover each problem, correct it, and document the corrective action taken. Use the Problem Resolution and Verification table to document the problem discovered, the affected devices, and the solution to the problem, including the commands used. Note: For each device, after issuing corrective commands, copy the running config to the startup config. Tip: If connecting from one device to another via SSH, issue the terminal monitor command so that console and debug messages generated on the remote device can be viewed on the local console.
