Layer 3 Routing Commands 1661
The type of IP operation (ICMP echo) must be configured before any other
operational parameter. To change the operation values (destination-ip-
address or source-interface-name) of an existing scheduled IP SLAs ICMP
echo operation, stop the IP SLA operation using the no ip sla schedule
operation-number or delete the IP SLA operation (using the no ip sla global
configuration command) and then reconfigure the operation with the desired
values.
The IP SLA ICMP echo operation supports both IPv4 and IPv6 addresses.
Command History
Command introduced in version 6.6 firmware.
Example
In the following example, SLA 55 is created with an ICMP echo to
172.16.1.175 and then scheduled. Tracking object 10 is created using the
default reachability test and is associated with IP SLAs operation 55 and then
an up delay of 5 seconds and a down delay of 3 seconds is configured:
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
console(config)#track 10 ip sla 55
console(config-track)#delay up 5 down 3
In the following example, IP SLA operation 13 is created and configured as an
echo operation using the ICMP protocol and the destination IPv6 address
3001:CD6:200::1 :
console(config)#ip sla 13
console(config-ip-sla)#icmp-echo 3001:CD6:200::1
frequency
Use the frequency command to configure the rate at which a specified IP
Service Level Agreement (SLA) operation repeats. To return to the default
value, use the no form of the command.
