User Guidelines Start configuring an IP SLA operation by using the ip sla command. This command specifies an identification number for the operation. Once this command is entered, the router enters IP SLA configuration mode. At a minimum, an SLA consists of an operation, a tracking object and one or more routes. Routes are associated with a tracking object which is mapped to an operation. Operations may be scheduled. The tracking object maintains the state of the operation, and the associated routes are withdrawn or added to the routing table based upon the state of the tracking object. See the track ip sla command for information on tracking objects. This command is supported for both IPv4 and IPv6 networks. The maximum number of IP SLAs supported is 128 (IPv4 and IPv6 combined). Once an operation is configured it needs to be scheduled to be started. Refer to the ip sla schedule global configuration command for more details on scheduling of an operation. NOTE: The configuration of an operation cannot be modified after an operation has been scheduled to start. For modifying the configuration after the operation is scheduled, the schedule must be stopped (using the no ip sla schedule command) or the operation must be deleted (using the no ip sla command). To display the current operational state of an IP SLA operation, use the show ip sla configuration command. Command History Command introduced in version 6.6 firmware. Example In the following example, operation 55 is configured as a ICMP Echo operation in an IPv4 network and is scheduled to start. The example shows the ip sla schedule command being used in an IPv4 network. console(config)# ip sla 55 console(config-ip-sla)# icmp-echo 172.16.1.175 console(config-ip-sla-echo)# exit console(config-ip-sla)# exit console(config)# ip sla schedule 55 Layer 3 Routing Commands 1655
