IP sla In Cisco router

Configuring a Basic ICMP Echo Operation 

Router cisco 1800

SUMMARY STEPS

1.    enable 
2.    configure terminal 
3.    ip sla operation-number 
4.    icmp-echo {destination-ip-address | destination-hostname} [source-ip {ip-address | hostname} |source-interface interface-name] 
5.    frequency seconds 
6.    end


Example

ip sla responder

ip sla 10
 icmp-echo 192.168.1.1 source-interface GigabitEthernet0/5
 threshold 100
 timeout 1000
 frequency 3

ip sla schedule 10 life forever start-time now

ip sla 20
 icmp-echo 192.168.2.1 source-interface GigabitEthernet0/4
 threshold 100
 timeout 1000
 frequency 3

ip sla schedule 20 life forever start-time now


track 10 ip sla 10 reachability
 delay down 1 up 1
!
track 20 ip sla 20 reachability
 delay down 1 up 1


ip route 10.0.1.0 255.255.255.0 192.168.1.1 name PRI track 10
ip route 10.0.1.0 255.255.255.0 192.168.2.1 2 name RDN track 20

SUMMARY STEPS

1. enable

2. configure terminal

3. ip sla monitor operation-number

4. type echo protocol ipIcmpEcho {destination-ip-address | destination-hostname} [source-ipaddr {ip-address | hostname} | source-interface interface-name]

5. frequency seconds

6. exit

7. ip sla monitor schedule operation-number [life {forever | seconds}] [start-time {hh:mm[:ss] [month day | day month] | pending | now | after hh:mm:ss] [ageout seconds] [recurring]

8. exit
9. track object-number rtr operation-number { state| reachability }

Example

The following example shows the configuration of the IP SLAs ICMP Echo operation number 6 that will start immediately and run indefinitely.

 ip sla monitor 10
       type echo protocol ipIcmpEcho 172.29.139.134 source-ipaddr 172.29.139.132
       threshold 100
       timeout 1000
       frequency 3
 !
 ip sla monitor schedule 6 life forever start-time now

 track 10 rtr  10 reachability

 delay down 1 up 1

 ip sla monitor 20
       type echo protocol ipIcmpEcho 172.29.139.134 source-ipaddr 172.29.139.1
       threshold 100
       timeout 1000
       frequency 3
 !
 ip sla monitor schedule 6 life forever start-time now

 track 20 rtr  20 reachability

 delay down 1 up 1
