Objectives
Part 1: Build the Network and Configure Basic Device Settings
Part 2: Configure and Observe IP SLA Operations
Part 3: Configure and Observe HSRP IP SLA Tracking
Background / Scenario
Cisco IP service level agreements (SLAs) allow users to monitor network performance between Cisco devices (switches or routers), or from a Cisco device toa remote IP device. Cisco IP SLAs can be applied to VoIP and video applications as well as monitoring end-to-end IP network performance.
Note: This lab is an exercise in deploying and verifying IP SLAs and does not necessarily reflect networking best practices. The IP SLA itself is an additional task that must be performed by the switch CPU. A large number of intensive SLAs could create a significant burden on the CPU, possibly interfering with other switch functions and having detrimental impact on the overall device performance. Therefore, you should carefully evaluate the benefits of running IP SLAs. The CPU load should be monitored after the SLAs are deployed to verify that they do not stress the device’s CPU above safe limits.
Note: The routers used with CCNP hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 3650s with Cisco IOS XE Release 16.9.4 (universalk9 image) and Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.
Note: Make sure that the switches have been erased and have no startup configurations. If you are unsure, contact your instructor.
Note: The default Switch Database Manager (SDM) template on a Catalyst 2960 does not support IPv6. You must change the default SDM template to the dual-ipv4-and-ipv6 default template using the sdm prefer dual-ipv4-and-ipv6 default global configuration command. Changing the template will require a reboot.
Answers Note: Refer to the Answers Lab Manual for the procedures to initialize and reload devices
Required Resources

- Set the clock on each switch to UTC time.
- Save the running configuration to startup-config.
Step 3:Configure the PCs for network connectivity.
Configure PC1 and PC2 for DHCP and SLAAC.
Part 2:Configure and Observe IP SLA Operations
In Part 2 you will configure and observe IP SLA operations. The SLA itself is simply a testing mechanism. Our example will test for simple reachability with an ICMP echo, but SLAs can do a lot more with many other protocols.
For now, all you will do is configure and schedule the IP SLAs and then query their status. This way you see the SLA operation separate from any application it might be used for.
Step 1:Create IP SLAs on switch D1.
- Create IP SLA 4 using the command ip sla 4. The number 4 is locally significant and could be any number between 1 and 2147483647.
Open configuration window
D1(config)# ip sla 4
- Configure IP SLA 4 to send an icmp-echo to the IPv4 address 192.168.1.1 and set the frequency for the ping to be every 15 seconds.
D1(config-ip–sla)# icmp-echo 192.168.1.1
D1(config-ip–sla–echo)# frequency 15
D1(config-ip–sla–echo)# exit
- Create IP SLA 6.
D1(config)# ip sla 6
- Configure IP SLA 6 to send an icmp-echo to the IPv4 address 2001:db8:acad:1000::1 and set the frequency for the ping to be every 15 seconds.
D1(config-ip–sla)# icmp-echo 2001:db8:acad:1000::1
D1(config-ip–sla–echo)# frequency 15
D1(config-ip–sla–echo)# exit
- Use the ip sla schedule command to configure both SLA 4 and SLA 6 with a life of forever and to start immediately.
D1(config)# ip sla schedule 4 life forever start-time now
D1(config)# ip sla schedule 6 life forever start-time now
Step 2:Observe IP SLA operation.
- Issue the command show ip sla summary to see a summarized status of the SLAs now that you have scheduled them.
D1# show ip sla summary

- To test and see what response the SLAs give in a failure, issue the shutdown command on R1 interface G0/0/0, then issue the show ip sla summary command again.

Close configuration window
- Issue the no shutdown command on R1 interface G0/0/0.
- Configure the same IP SLAs on Switch D2. Verify them in the same manner, issuing the shutdown command on R3 interface G0/0/0. When you have verified that SLA is tracking reachability to R2 interface Loopback 0, issue the no shutdown command on R3 interface G0/0/0.
Part 3:Configure and Observe HSRP IP SLA Tracking
In this part, we will put the IP SLAs that you created into use, and you can see how they work. In this case, our network is operational and HSRP is providing first-hop redundancy. HSRP will react to a directly connected interface that is failing or coming online, as you saw in the tracking section of the HSRP lab. But what if there is an indirect link failure that makes the active HSRP router less desirable? The IP SLA will allow us to handle this scenario. For this example, we will treat R2 interface Loopback 0 as a critical entity on the internet, like a DNS server. The organizational policy is that if that DNS server is not reachable from the gateway, the gateway should not be used.
Step 1:Verify HSRPv2 is operational.
- Verify that HSRP is active and operating on Switch D1 with the show standby brief command.
Open configuration window

P indicates configured to preempt.

As you can see from the output, switch D1 is the active virtual router for VLAN 2 and the standby for VLAN 3 for both IPv4 and IPv6.
- From PC1, start a continuous ping to 192.168.1.1.
- On D1, issue the shutdown command on interface VLAN 2. You should see that HSRP fails over to D2 as the Active Virtual Router for VLAN 2, and the pings continue to succeed. When verified, issue the no shutdown command on switch D1 interface VLAN 2.
- From PC2, start a continuous ping to 192.168.1.1.
- On D2, issue the shutdown command on interface VLAN 3. You should see that HSRP fails over to D1 as the Active Virtual Router for VLAN 3, and the pings continue to succeed. When verified, issue the no shutdown command on switch D2 interface VLAN 3.
- Now issue the shutdown command on R1 interface G0/0/0 and R3 interface G0/0/0. Note that there is no impact on either D1 or D2 regarding HSRP, and the pings start failing. Stop the continuous pings on PC1 and PC2 and issue the no shutdown command on R1 interface G0/0/0 and R3 interface G0/0/0.
Step 2:Reconfigure HSRP to use the IP SLA.
- Create a track object using the command track [number] ip sla [sla number].
D1(config)# track 4 ip sla 4
- Set the delay timers. These are used to help manage changes on flapping links. In this case, R2 interface Loopback 0 is known to D1 and D2 via OSPF, so the delay needs to take OSPF timers into account. The command is setting the SLA up so that it will wait a period of time after the first failed SLA to make sure it is actually down, and it will wait a period of time after it appears to be returned to operation to be sure it is actually operating.
D1(config-track)# delay down 45 up 20
D1(config-track)# exit
- Configure track 6 to pay attention to IP SLA 6 with the same delay values.
D1(config)# track 6 ip sla 6
D1(config-track)# delay down 45 up 20
D1(config-track)# exit
- Now that the IP SLAs are being tracked, we must associate the status of the track with the HSRP group. This is done on the VLAN interface using the standby [group] track [track number] command. As a part of that command, add a decrement value, which will drop the interface’s HSRP priority should the IP SLA fail.
D1(config)# interface vlan 2
D1(config-if)# standby 2 track 4 decrement 60
D1(config-if)# standby 26 track 4 decrement 60
D1(config-if)# exit
D1(config)# interface vlan 3
D1(config-if)# standby 3 track 4 decrement 60
D1(config-if)# standby 36 track 4 decrement 60
D1(config-if)# exit
Close configuration window
- Repeat the same commands on D2 so that HSRP is tracking IP SLAs there as well.
Open configuration window
D2(config)# track 4 ip sla 4
D2(config-track)# delay down 45 up 20
D2(config-track)# exit
D2(config)# track 6 ip sla 6
D2(config-track)# delay down 45 up 20
D2(config-track)# exit
D2(config)# interface vlan 2
D2(config-if)# standby 2 track 4 decrement 60
D2(config-if)# standby 26 track 4 decrement 60
D2(config-if)# exit
D2(config)# interface vlan 3
D2(config-if)# standby 3 track 4 decrement 60
D2(config-if)# standby 36 track 4 decrement 60
D2(config-if)# exit
Close configuration window
Step 3:Observe and validate HSRPv2 operation with IP SLAs.
- On PC1, start a continuous ping to 192.168.1.1.
- On R1, shutdown interface G0/0/0.
- After about 45 seconds, you should see that HSRP fails over for VLAN 2 from switch D1 to switch D2, and pings from PC1 work again.
- Issue the no shutdown command on R1 interface G0/0/0.
- Switch D1 takes over again as the Active Virtual Router for VLAN 2, and the host is still able to ping 192.168.1.1.
- Stop the continuous ping running on PC1.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
