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 operation.
DUT(config-ipsla)#vrf vpn1 (Optional)Configure the IP SLA entry
parameters:
To use IP SLA operations in VPNs.
DUT(config-ipsla)#exit Exit the IP SLA mode.
DUT(config)# ip sla monitor schedule 1 Enable an IP SLA entry
