ICMP measurement profiles specify a parameter set used by measurements that are based on ICMP pings. Interface metrics are derived from measurements to quantify the connection quality. These metrics are: Average round trip time (RTT, latency), jitter and packet loss rate.
To configure the ICMP measurement profiles, navigate to the view .
- Measurement-Profile
- The name of the profile. This name is used to reference the profile in DPS policies.
- DSCP value
- Sets the DSCP value in the IP header of measurement packets. DSCP (Differentiated Services Code Point) is used for QoS (Quality of Service).
- Source address (optional)
- References a named loopback address that is used as the sender in the measurement packets. If the field is left empty, the router automatically selects an address that matches the sending interface.
- IPv4 destination 1-4
- Up to 4 measurement targets as valid IPv4 unicast addresses or DNS host names. With 0.0.0.0 entered, the measurement target is determined dynamically by the VPN. If the field is left empty, no measurements are made for this family of addresses.
- IPv6 destination 1-4
- Up to 4 measurement targets as valid IPv6 unicast addresses or DNS host names. With :: entered, the measurement target is determined dynamically by the VPN. If the field is left empty, no measurements are made for this family of addresses.
- Payload size
- Specifies the size of the data payload that follows the ICMP header (payload size) of the pings being sent.
- Interval
- The interval in seconds between 2 measurements. The maximum round trip time is also specified. Packets not answered within a measurement interval are counted as packet loss.
- Unit
- Specifies whether the ICMP measurements for the value should be in seconds or milliseconds. Possible values: Seconds (default), milliseconds.
- Sliding-Window
- Maximum number of measurement values that are used to determine the interface metrics. If a measurement value is received after the number specified here has been reached, the oldest measurement is discarded.
