I want to make sure I have timeout and threshold straight as used in Ip sla. One video series seems to be saying the opposite of what I think. I am thinking that threshold is the time when exceeded turns the sla to down and if timeout is exceeded the sla is considered unreachable. Maybe there is a better way to.

The above configuration defines and starts an IP SLA probe. The ICMP Echo probe sends an ICMP Echo packet to next-hop IP 188.8.131.52 every 3 seconds, as defined by the frequency parameter. Timeout sets the amount of time (in milliseconds) for which the Cisco IOS IP SLAs operation waits for a response from its request packet (config)# ip sla 1 (config-ip-sla)# udp-echo 100.100.100.2 5000 (config)#ip sla sch 1 start-time now.

Anyone able to share ip sla setup on cisco for monitoring gre service availability? i am aware of the best practice published on the public kb, however sla seems to fail often, possibly due to local packet loss. Any proven setup to share? timeout value? threshold? frequency? thanks The IP SLA responder is available only on Cisco IOS software-based devices, including some Layer 2 switches that do not support full IP SLA functionality. Follow these steps to configure the IP SLA responder on the target device (the operational target) The best and simplest way to achieve WAN redundancy on Cisco devices is to use Reliable Static backup routes with IP SLA tracking. IP SLAs is a feature included in the Cisco IOS Software that can allow administrators the ability to Analyze IP Service Levels for IP applications and services.IP SLA's uses active traffic-monitoring technology to monitor continuous traffic on the network

Second, we need to configure a track object to check the status of the IP SLA monitor. track 1000 ip sla 1000 reachability delay down 30 up 30. Finally, we can create a static route and tie it to the tracked object The Dead Gateway Detection (4.3 & 5.0) or Link Health Monitor (5.2) allows the FortiGate unit to ping a gateway at regular intervals to ensure it is online and working. When the gateway is not accessible, that interface is marked as down. This feature is similar to Cisco's IP SLA feature. Policy routing takes precedence over the IP routing table

Hi, There's a complex task to configure static nat with ip sla on cisco router 2951 Description: There're 2 ISPs (2 physical links to providers). Users access Internet through 1st ISP (dynamic NAT) and servers access internet through 2nd ISP (static nat + port forwarding). both servers and users are in the same network, connected via one router interface and have the same default gateway ip addr I think this is not possible and the 2930f switch has limited routing support. Also the 3810 and 5400 doesn't support ip sla I think. However there is OSPF support on the 2930f and the high and series support advanced routing including bgp 2. threshold 2 ip sla monitor schedule 1 life forever start-time now Next we create a tracked object.

IP SLA is the most recent incarnation of a set of remote ping technologies progressively introduced over the last 20 years by Cisco - the initial version RTTMON (Round-trip Time Monitor), introduced in 1995 allowed network administrators to configure routers to ping other network devices and report on their response time Router(config-ip-sla-jitter)#timeout 2000 %Error: timeout is less than threshold 5000 But when using SNMP, certain IOS versions do not check for this condition and allow setting timeout to a value smaller than the threshold.
