7.2 Troubleshoot network connectivity issues using ICMP echo-based IP SLA

To enable an SLA use the following commands:
Router(config)#ip sla 1
 Router(config-ip-sla)#icmp-echo source-ip
 Router(config-ip-sla-echo)#frequency 5
 Router(config-ip-sla-echo)#threshold 300
 Router(config-ip-sla-echo)#history filter all
 Router(config-ip-sla-echo)#history buckets-kept 6
 Router(config-ip-sla-echo)#history lives-kept 1

The output of show ip sla summary can be useful in determining connection issues based on number of dropped pings.
