• Define the parameter "size" to indicate the size of the ICMP packet

during the PING test using ICMP protocol. A default value of 32 bytes

meets most requirements.

•

Define the parameter "timeout" to indicate the number of milliseconds

to wait for a response. The default value is 1000. This means you

can expect feedback on the PING command within 1 second. For

some environments, 1000 is too small a number, and depending on

your network topology and system resources, a larger value can be

appropriate.

Nortel recommends limiting the definition of system to systems that must

be verified and are expected to respond. Do not define an excessively

long timeout. The larger the number of the system and the larger the

possible timeout, the less responsive the system. This means that the

processing time increases, and the number of verifications decreases.

The following figure shows an example of a definition of a system for

PING.

The message to be sent when a system is no longer responding

to an ICMP check and the destinations informed are defined in the

"NotResponding" section.

The message to be sent when a system resumes responding to an ICMP

check and the destinations informed are defined in the "Responding"

section.
