Cacti Monitoring of Cisco IP SLA

• http://www.cisco.com/en/US/docs/ios/12_4/ip_sla/configuration/guide/hsthresh.html

  •          At times of high
             network activity, an ICMP ping test often shows a long and inaccurate response time, while an Cisco IOS
             IP SLAs test shows an accurate response time due to the time stamping on the responder.
