Element Description
Name The object name, which can be up to 128 characters. Object names are
not case-sensitive. For more information, see Creating Policy Objects,
page 6-9.
Description An optional description of the object.
SLA Monitor ID The ID number of the SLA operation. Values range from 1 to
2147483647. You can create a maximum of 2000 SLA operations on a
device. Each ID number must be unique to the policy and the device
configuration.
Monitored Address The IP address that is being monitored for availability by the SLA
operation. For recommendations on selecting an address to monitor, see
Monitoring Service Level Agreements (SLAs) To Maintain
Connectivity, page 50-7.
Interface The source interface for all ICMP echo requests sent to the monitored
address to test its availability. Enter the name of an interface or
interface role, or click Select to select an it from a list or to create a new
interface role.
Frequency The frequency of ICMP echo request transmissions, in seconds. Values
range from 1 to 604800 seconds (7 days). The default is 60 seconds.
Note The frequency cannot be less than the timeout value; you must
convert frequency to milliseconds to compare the values.
Threshold The amount of time that must pass after an ICMP echo request before
a rising threshold is declared, in milliseconds. Values range from 0 to
2147483647 milliseconds. The default is 5000 milliseconds.
The threshold value is used only to indicate events that exceed the
defined value. You can use these events to evaluate the proper timeout
value. It is not a direct indicator of the reachability of the monitored
address.
Note The threshold value should not exceed the timeout value.
Time out The amount of time that the SLA operation waits for a response to the
ICMP echo requests, in milliseconds. Values range from 0 to
604800000 milliseconds (7 days). The default is 5000 milliseconds.
If a response is not received from the monitored address within the
amount of time defined in this field, the static route is removed from the
routing table and replaced by the backup route.
Note The timeout value cannot exceed the frequency value (adjust
the frequency value to milliseconds to compare the numbers).
