21 Configuring VRRP Remote Tracking
21.1 Configuring IP SLA
This chapter describes how to configure ip sla.
21.1.1 Understanding IP SLA
IP SLA(Service Level Agreement) is a network performance measurement and
diagnostics tool that uses active monitoring. Active monitoring is the generation of
traffic in a reliable and predictable manner to measure network performance. Every
IP SLA operation maintains an operation return-code value. This return code is
interpreted by the tracking process. The return code can return OK, OverThreshold,
and several other return codes. Different operations can have different return-code
values, so only values common to all operation types are used. In IP SLA, use icmp
echo to check state or reachability of a route.
21.1.2 Configuring IP SLA
Configuring the ICMP echo
Beginning in privileged EXEC mode, follow these steps to configure the ICMP
echo:
Command Description
DUT#configure terminal Enter the Configure mode.
DUT(config)# ip sla monitor
1 Create an IP SLA entry or enters IP
SLA monitor configuration mode.
DUT(config-ipsla)# type echo
protocol ipIcmpEcho
192.168.0.1 Defines an Echo operation with icmp
packet and enters destination ip
address or hostname.
DUT(config-ipsla)#frequency
10 (Optional)Configure the IP SLA entry
parameters:
Sets the rate at which a specified IP
SLA operation repeats.
DUT(config-ipsla)#timeout 5 (Optional)Configure the IP SLA entry
parameters:
Sets the amount of time an IP SLA
operation waits for a response from its
request packet.
DUT(config-ipsla)#threshold
1 (Optional)Configure the IP SLA entry
parameters:
Sets the upper threshold value for
calculating network monitoring
statistics created by an IP SLA
