CCNP TSHOOT Chapter 3 Lab 3-1, Assembling Maintenance and Troubleshooting Tools (Version 7)

Topology

Objectives

• Assign responsibility for a device or set of devices to team members (optional).
• Load the baseline configuration for each device in the topology.
• Use available tools to document key device configuration parameters, such as the interfaces in use, IP addressing, routing protocols, VLANs, logging mechanisms, and security measures.
• Document the physical topology to support future troubleshooting tasks.
• Document the logical topology to support future troubleshooting tasks.

Background

You have been employed as a network engineering consultant by a company that has made a recent acquisition. The documentation for the acquired company’s network is incomplete and outdated, so you need to inventory their network architecture both logically and physically, per company documentation standards. This will help you learn about the design and implementation of their network and ensure that you have access to up-to-date and accurate network documentation to reference during future troubleshooting procedures. One directive to your predecessor was to transition access layer switches to multilayer switches, so static routing is implemented on the access layer switches until new multilayer switches are procured.

In this lab, you survey the baseline TSHOOT network. No problems are introduced in this lab. The TSHOOT network will evolve over time as changes and enhancements are made. You will analyze and document the current topology and device configuration parameters to develop familiarity with the baseline configurations and network connections. You will review and fill out the provided documentation as you analyze the network. You will assess and assemble tools that can be used for future maintenance and troubleshooting tasks.

Note: 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 switches have Fast Ethernet interfaces, so the routing metrics for all Ethernet links in the labs are calculated based on 100 Mb/s, although the routers have Gigabit Ethernet interfaces. The 3560 and 2960 switches are configured with the SDM templates dual-ipv4-and-ipv6 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. Catalyst 3650 switches (running any Cisco IOS XE release) and Catalyst 2960-Plus switches (running any supported Cisco IOS image) can be used in place of the Catalyst 3560 switches and the Catalyst 2960 switches.

Required Resources

• 3 routers (Cisco IOS Release 15.4 or comparable)
• 2 multilayer switches and 1 access layer switch (Cisco IOS Release 15.0(2) or comparable with Fast Ethernet interfaces)
• SRV1 (PC with static IP address): Windows 7 with RADIUS, TFTP, and syslog servers, plus an SSH client, SNMP monitor, and WireShark.
• PC-B (DHCP client): Windows 7 with SSH client and WireShark software
• PC-C (DHCP client): Windows 7 with SSH client and WireShark software
• Serial and Ethernet cables, as shown in the topology
• Rollover cables to configure the routers and switches via the console

Task 1: Assign Responsibility for Each Device (optional)

Step 1: Review the lab topology together with your team members.

Step 2: Assign responsibility for each device to a team member.

a. The team member who has primary responsibility for a device is in control of the console of that device and changes to that device. No other team member should access the console, make changes to the device, or execute disruptive actions, such as reloading or debugging, without permission from the responsible team member.

b. All team members can access all devices via Telnet or SSH for non-disruptive diagnostic action without permission of the responsible team member. Responsibilities can be reassigned during later labs if necessary.

c. If working in teams, document responsibilities in the Device Responsibilities table.

Device Responsibilities Table

Task 2: Load the Baseline Device Configuration Files

Use the following procedure on each device in the network to load the baseline configuration. The procedure shown here is for a switch, but it is very similar to that of a router.

Note: The configuration files for this lab include ip host name ip-addr entries for all devices. This can be helpful in accessing devices using Telnet with this lab. The ip host entries are only provided in this BASE lab, as the device IP addresses will change in subsequent labs.

Step 1: Verify the existence and location of the lab configuration files.

The course lab configuration files for a particular device should be in flash under the tshoot directory. 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 instructor.

Note: When the show flash command is used on a switch, it lists the directories and files at the root directory but not the files within the directories. The following example uses the cd and dir commands on switch ALS1.

ALS1# show flash

Directory of flash:/

    9  -rwx         916  Feb 28 1993 16:04:03 -08:00  vlan.dat

    9  -rwx        7979  Sep 22 2014 11:26:14 -07:00  BASE-ALS1-Cfg.txt

Alternatively, you can see the contents of the directory by specifying its name using the dir command. For example:

ALS1# cd
ALS1# pwd
flash:
ALS1# dir flash:/tshoot
Directory of flash:/tshoot/

      9 -rwx 7979 Sep 22 2014 11:26:14 -07:00 BASE-ALS1-Cfg.txt
<output omitted>

Note: When the show flash command is used on a router, it lists the directories and the files within them. The following example uses only the show flash command on router R1. The tshoot directory and its contents are listed.

R1# show flash:
-#- --length-- -----date/time------ path
1    103727964 Sep 18 2014 05:20:10 -07:00 c2900-universalk9-mz.SPA.154-3.M.bin
2         2857 Feb 22 2014 01:01:52 -08:00 pre_autosec.cfg
3            0 Sep 22 2014 11:39:18 -07:00 tshoot
4         3887 Sep 22 2014 11:42:20 -07:00 tshoot/BASE-R1-Cfg.txt

Step 2: Erase startup-config from NVRAM, and then reset the SDM template.

ALS1# erase startup-config 
Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
[OK]
Erase of nvram: complete
ALS1#
Sep 26 22:00:26.222: %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
ALS1# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
ALS1(config)# sdm prefer lanbase-routing
ALS1(config)#
Sep 26 22:00:45.155: %PARSER-5-CFGLOG_LOGGEDCMD: User:console  logged command:sdm prefer lanbase-routing 
ALS1(config)# exit
ALS1#
Sep 26 22:00:48.393: %SYS-5-CONFIG_I: Configured from console by console
ALS1# show sdm prefer
 The current template is "lanbase-routing" template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 0 routed interfaces and 255 VLANs. 

  number of unicast mac addresses:                  4K
  number of IPv4 IGMP groups + multicast routes:    0.25K
  number of IPv4 unicast routes:                    4.25K
    number of directly-connected IPv4 hosts:        4K
    number of indirect IPv4 routes:                 256
  number of IPv6 multicast groups:                  0.375k
  number of IPv6 unicast routes:                    1.25K
    number of directly-connected IPv6 addresses:    0.75K
    number of indirect IPv6 unicast routes:         448
  number of IPv4 policy based routing aces:         0
  number of IPv4/MAC qos aces:                      0.125k
  number of IPv4/MAC security aces:                 0.375k
  number of IPv6 policy based routing aces:         0
  number of IPv6 qos aces:                          0.375k
  number of IPv6 security aces:                     127

Note: For a 3560 switch, use the “dual-ipv4-and-ipv6 routing” template. If using another type of Cisco switch, choose an SDM template that supports IPv4/IPv6 routing and IPv4/IPv6 ACEs. The SDM setting reverts to the “default” template on a 2960 and the “desktop default” template on the 3560 after deleting startup-config, so it is important to change the SDM template setting after deleting startup-config. Most time-stamped logging messages, as seen in the output above, will be removed from the lab outputs going forward.

Step 3: Delete the VLAN database from flash (switches only).

ALS1# delete vlan.dat 
Delete flash:/vlan.dat? [confirm]

Step 4: Reload the device, but do not save the system configuration if prompted.

ALS1# reload

System configuration has been modified. Save? [yes/no]: no
Proceed with reload? [confirm]

Step 5: When the device restarts, do not enter the initial configuration dialog.

Press RETURN to get started!

           --- System Configuration Dialog ---

Enable secret warning
----------------------------------
In order to access the device manager, an enable secret is required
If you enter the initial configuration dialog, you will be prompted for the enable secret
If you choose not to enter the intial configuration dialog, or if you exit setup without setting the enable secret,
please set an enable secret using the following CLI in configuration mode-
enable secret 0 <cleartext password>
----------------------------------
Would you like to enter the initial configuration dialog? [yes/no]: no

Note: On some platform/IOS combinations, a message appears after choosing not to enter the initial configuration dialog, asking whether or not to “terminate autoinstall”. If this message appears, enter yes to terminate autoinstall.

Step 6: Copy the specified lab device configuration file from flash to running-config.

Switch> enable
Switch# copy flash:/tshoot/BASE-ALS1-Cfg.txt running-config
Destination filename [running-config]?

Note: Although it is possible to copy the file to startup-config and reload the device, the RSA keys for SSH cannot be generated from the startup-config file. The device configuration files loaded from flash contain commands that remove any existing keys and create new keys.

It is also possible to cut-and-paste the

Step 7: Copy the running config to the startup config.

Depending on the platform/IOS combination, AUTOSAVE may automatically save a copy of running-config to NVRAM for startup. AUTOSAVE does not copy the console line and vty line configurations from running-config to startup-config. To ensure that the startup configuration is complete, manually copy:

ALS1# copy running-config startup-config
Building configuration...
[OK]

Note: If the device is rebooted at this point, you can log in with the username cisco and the password cisco. To access privileged EXEC mode, use the enable secret: cisco.

Step 8: Repeat Steps 1 through 7 for the other devices in the network.

Step 9: Configure the PCs.

a. Configure SRV1 with the static IPv4 address 10.1.100.1/24 and default gateway 10.1.100.254 (on DLS1). Configure SRV1 with the static IPv6 address 2001:DB8:CAFE:100::1 and default gateway 2001:DB8:CAFE:100::D1 (on DLS1).

b. Configure PC-B and PC-C as DHCP clients for both IPv4 and IPv6.

Note: Make sure the PC’s learn addresses of the form 2001:DB8:CAFE:x:ABCD:u:v:w where x is the VLAN for the respective PC. Use ipconfig/release6 followed by ipconfig/renew6 to release and renew the stateful IPv6 data. If necessary, reset the NIC. The SVI commands for VLANs 110, 120, and 200,

ipv6 nd prefix 2001:DB8:CAFE:x::/64 no-autoconfig
ipv6 nd managed-config-flag

set the IPv6 RA M, O, and A flags so that the Windows 7 stateful DHCPv6 clients populate a singular GUA and appropriate link-local default routes, as seen in the ipconfig and route print outputs.

Step 10: Test basic network connectivity between devices.

a. Ping from PC-B to SRV1 at 10.1.100.1 and 2001:DB8:CAFE:100::1. Were the pings successful?
_________________________________________________________________

b. Ping from ALS1 to R2 Lo1 at 2.2.2.2 and 2001:DB8:EFAC::2. Were the pings successful?
_________________________________________________________________

Note: If the pings are not successful, contact your instructor.

Task 3: Analyze and Document the Physical Lab Topology

Note: At this time, only examine and document the physical connections. Documenting the logical topology, such as subnets, IP addresses, and routing protocols, is addressed in Task 4 of this lab.

Step 1: Review the physical topology diagram on page 1 of the lab.

Step 2: Use Cisco Discovery Protocol and show commands to verify the Layer 1 and Layer 2 connections of the lab topology.

a. Use the show cdp command to discover the interfaces associated with the physical connections. Fill in the correct device and interface designators in the following Device Links table and label them on the physical topology diagram on the first page of the lab.

b. Review the configurations of the devices for using Layer 1 and Layer 2 features, such as trunks and EtherChannels. Fill in the information in the Device Links table and add it to the diagram. If a link is accounted for from one device to another, it is not necessary to repeat the entry from the other device. The first entry for ALS1, interface F0/1 is filled in as an example.

Which other commands could you use to identify Layer 1 and Layer 2 characteristics?
_________________________________________________________________

Device Links Table

c. Verify that all physical links shown in the diagram are operational. Which commands did you use?
____________________________________________________________________

Step 3: Map the VLANs used in the lab to the devices in the diagram.

Fill in the VLAN Definition table and label the physical topology diagram with the VLANs used for this topology. Identify all host devices that are members of each VLAN. The first entry for VLAN 99 is filled in as an example.

VLAN Definition Table

Step 4: Analyze spanning tree for the Layer 2 switched domain.

a. Analyze the spanning tree characteristics of the Layer 2 switched portion of the network. Which type of spanning-tree mode is implemented?
_________________________________________________________________

b. Which switch is the root switch for each VLAN, and what are the configured spanning-tree priorities?
_________________________________________________________________

c. What is the resulting spanning-tree topology for VLANs that have client devices connected?
_________________________________________________________________

d. Which commands did you use to analyze the spanning-tree characteristics?
_________________________________________________________________

Step 5: Diagram the spanning tree for VLAN 120.

a. Label the STP role and port status for each port channel used in the physical topology diagram below.

b. If working as a team, discuss your findings with your teammates to ensure that all team members understand the physical and data link aspects of the network design.

Task 4: Analyze and Document the Logical Lab Topology

Step 1: Review the logical lab diagram and the subnets.

Review the IP subnets in the Subnet table for the VLANs and WAN links that are used in the lab network. Router interface designations from the physical topology diagram are provided in two copies of the logical topology, one to be used for IPv4 data and one for IPv6 data.

Subnet Table

Step 2: Map the subnet scheme to the logical diagram.

In the previous step, the subnets were documented in the Subnet table. Now document the host portion of the addresses. To document the host part, research the routing tables and interface IP addresses of all the devices. Document the interface IPv4 and IPv6 addresses in the IP Address table and on the associated logical topology diagram. Use only the number of the last octet for IPv4 addresses and the last hextet for IPv6 addresses in the respective diagrams. The device names and interfaces are listed to help identify the IP addresses. The entry for ALS1 VLAN 99 is shown as an example. If an interface is not in use, indicate this in the Additional Information column. Account for all physical and virtual interfaces.

IP Address Table

Step 3: Analyze and document control plane logical configuration features.

Analyze the configurations of the devices for control plane features such as routing protocols, First Hop Redundancy Protocols (FHRPs), dynamic host configuration protocol (DHCP), and network address translation (NAT). Review, document, and discuss the following aspects of the logical network configuration.

a. Is dynamic or static routing being used?
_____________________________________________________________

b. If dynamic, which routing protocol?
_____________________________________________________________

c. Are FHRPs in use, such as the Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), or Gateway Load Balancing Protocol (GLBP)? If yes, which one?
_____________________________________________________________

d. What is the active router for all relevant VLANs?
_____________________________________________________________

e. From the PC-B command prompt, issue the tracert command to router R2 Lo0 at 10.1.202.1 for IPv4 and 2001:DB8:CAFE:202:2 for IPv6. What path did the packets take in each case?
_____________________________________________________________

f. Are any access lists used to filter traffic on the network? If yes, describe their function.
_____________________________________________________________

g. Is DHCP in use? If yes, which DHCP server is used and for which VLANs present in the logical topology diagram?
_____________________________________________________________

h. How does ALS1 send ICMP echo requests to SRV1 in VLAN 100, when ALS1 has no VLAN 100?
_____________________________________________________________

i. If working as a team, discuss your findings with your teammates to ensure that all team members understand the high-level design of the network.

Task 5: Identify Troubleshooting and Maintenance Tools

Step 1: Analyze device configurations for troubleshooting and maintenance features.

Analyze the configurations of the devices for services that support troubleshooting and maintenance, such as syslog, Simple Network Management Protocol (SNMP), and other network management features.

Step 2: Document the troubleshooting and maintenance features.

a. Document the troubleshooting and maintenance applications or tools in use with the network devices in the Troubleshooting and Maintenance Tools table. An entry for system logging is provided as an example.

Troubleshooting and Maintenance Tools Table

b. If working as a team, discuss your findings with your teammates to ensure that all team members know which maintenance and troubleshooting tools are available in the network.

Notes

Use this space to make any additional notes regarding troubleshooting and maintenance applications or tools.
______________________________________________________________

Task 6: Identify the Security Measures Implemented

Step 1: Analyze device configurations for security-related features.

Analyze the configurations of your assigned devices for configuration options that help support a more secure network implementation, such as password security, login authentication, secure remote management, switch trunk and access port security, and VLANs. Record your entries in the Security Features table. An entry for password security is provided as an example.

Security Features Table

Notes

Use this space to make any additional notes regarding security measures.
_________________________________________________________________

Note: Configuration command sequences for all devices are provided at the end of the lab. These are not outputs resulting from entering the show running-config command. Only the non-default commands used to configure the devices are included (along with no shutdown on appropriate interfaces).

Lab Debrief Notes

Use this space to make notes regarding the key concepts learned during the lab debrief discussions with your instructor. This may include alternate solutions, methods, and processes; this may include procedure and communication improvements; and this may include key commands and tools.

Note: This is your primary opportunity to document a baseline of the lab network before starting the troubleshooting exercises. During the debrief session, ask your instructor for clarification of any aspects of the network design and configurations that are unclear.
