If a Next Hop Gateway is not specified, the probe assumes that the targets are directly connected to the Outbound Interface's network.
Ping (ICMP) - Explicit Route - This probe bypasses the route table and uses the source IP address of the interface specified in the Outbound Interface pull down menu to send a Ping to the targets. If a RST is received, no response is returned. When a SYN/ACK is received, a RST is sent to close the connection. A successful response will be counted independently for each probe target when the target responds with either a SYN/ACK or RST via thesame interface within the Response Timeout time window. A TCP SYN packet is sent to the probe target with the source IP address of the egress interface. TCP - This probe uses the route table to find the egress interface and next-hop for the defined probe targets. An echo response must return on the same interface within the specified Response Timeout time limit for the ping to be counted as successful. A Ping echo-request is sent out the egress interface with the source IP address of the egress interface. Ping (ICMP) - This probe uses the route table to find the egress interface and next-hop for the defined probe targets. Probe Type - Select the appropriate type of probe for the network monitor policy. You can dynamically create a new address object by selecting Create New Address Object. Objects within a Group object may be Host, Range, or FQDN Address Objects. Address Objects may be Hosts, Groups, Ranges, or FQDNs object. Probe Target - Select the Address Object or Address Group to be the target of the policy. Name - Enter a description of the Network Monitor policy. Enter the following information to define the network monitor policy. The Add Network Monitor Policy window is displayed. Click Network | System | Network Monitor. Click Network in the top navigation menu. To add a network monitor policy on the SonicWall security appliance, perform these steps. A list of resolved probe targets, and their status. The total number of successful probe responses received. The following information is displayed in the probe status. You can view details of the probe status by hovering your mouse over the green, red, or yellow light for a policy. Yellow indicates that the policy status is UNKNOWN. Red indicates that the policy status is DOWN. Green indicates that the policy status is UP. The Status column elements displays the status of the network connection to the target. Click Add button to configure network probes policy. Under Network | System | Network Monitor. Click Network in the top navigation menu. When the destination Address Object is a Group, Range or FQDN with multiple resolved addresses, Network Monitor probes each probe target and derives the NM Policy state based on the results. This Address Object may be a Host, Group, Range, or FQDN. The results and status of this monitoring are displayed dynamically on the Network Monitor page, and are also provided to affected client components and logged in the system log.Įach custom NM (Network Probe) policy defines a destination Address Object to be probed. The Network in the top navigation menu consists of Network Monitor services which provides a flexible mechanism for monitoring network path viability. The below resolution is for customers using SonicOS 7.X firmware. This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware.
