Configure RTR/SLA Ping in IOS

Download Template

This configures and schedules the pinging of a destination ip address. I tend to define "site codes" which is generally the third octet of a given site's /24 address space.

For example: Beijing, China = 192.168.56.0/24 , site code is "56"

rtr 56 type echo protocol ipIcmpEcho 192.168.56.1 frequency 300 rtr schedule 56 life forever start-time now

Once this is configured you can then use snmp to graph response times using the following oid: 1.3.6.1.4.1.9.9.42.1.2.10.1.1.%[destination_code]%

Example: snmpget -v 2c -c your_snmp_community source_router_ip 1.3.6.1.4.1.9.9.42.1.2.10.1.1.56

rtr %{destination_code}% type echo protocol ipIcmpEcho %{destination_ip}% frequency 300 rtr schedule %{destination_code}% life forever start-time now\ ----Version 12.2(55)SE---- conf t ip sla %{destination_code}% icmp-echo %{destination_ip}% frequency 300 ip sla schedule %{destination_code}% life forever start-time now end
