Cisco IOS IP SLAs is a feature that allows network administrators to monitor and measure key network metrics such as packet loss, jitter, latency and response times to help verify Quality of Service. It collects performance data in real-time from network devices and helps determine if traffic is meeting the required SLAs. Some examples of metrics that can be monitored include VoIP calls, DNS queries, DHCP response times, FTP transfers and HTTP downloads.

2.  What Is IP SLAs
Why we use IP SLAs
IP SLA Advantages
Example
IP Service Level Agreements (SLAs)

3. What Is IP SLAs?
• Is a feature of the Cisco Internetwork
Operating System (Cisco IOS).
• collect information about network
performance in real time.
• helps the administrator to verify Quality
of Service (QoS) levels.
• Ip sla with NMS.
• Previous name rtr(Response Time
Reporter).
• Release 12.4

4. IP SLA Operations
• dhcp
• dns
• echo
• frameRelay
• ftp
• http
• jitter
• pathEcho
• pathJitter
• slm atm interface
• slm atm pvc
• slm controller
• slm frame-relay interface
• slm frame-relay pvc
• slm interface
• tcpConnect
• udpEcho
• voip

 To see sla operations on cisco device:
#Show ip sla application
 Note:
Switch dose not support voip

5. Why we use IP SLAs

6. •Testing &monitoring:
VOIP,DNS,DHCP,jitter,FTP,HTTP….etc
•Routing :
Static route , PBR.

7. How its work?
• Responder not necessary for all
operations
• Use NMS with GUI

8. Cisco IOS IP SLAs can send SNMP
traps that are triggered by events
such as the following:
• Connection loss
• Timeout
• Round-trip time threshold
• Average jitter threshold
• One-way packet loss
• One-way jitter
• One-way mean opinion score (MOS)
• One-way latency

9. implement IP SLAs network performance
measurement
• Enable the IP SLAs responder, if
required.
• Configure the required IP SLAs
operation type.
• Configure any options available for the
specified operation type.
• Configure threshold conditions, if
required.
• Schedule the operation to run.
• Display and interpret the results of the
operation using the Cisco IOS CLI or a
network management system (NMS)
system with SNMP.

Configure ip sla operation:
• ip sla monitor 1
• type echo protocol ipIcmpEcho 172.16.0.1
• timeout 1000
• threshold 2
• frequency 3
• ip sla monitor schedule 1 life forever start-time
