Test Tools

Diagnosis > Network Tools > Test Tools

The device provides the following test tools:

• DNS Query: Queries the IP address of the specified domain name.
• Ping: Checks the network connecting status. The testing result contains two parts:
  • The Ping packet response. If there is no response from the target after timeout, it will print Destination Host Not Response, etc. Otherwise, the response contains sequence of packet, TTL and the response time.
  • Overall statistics, including number of packet sent, number of packet received, percentage of no response, the minimum, average and maximum response time.
• Traceroute: Traceroute is used to test and record gateways the packet has traversed from the originating host to the destination. It is mainly used to check whether the network connection is reachable, and analyze the broken point of the network. The common Traceroute function is performed as follows: first, send a packet with TTL 1, so the first hop sends back an ICMP error message to indicate that this packet cannot be sent (because of the TTL timeout); then this packet is re-sent, with TTL 2, TTL timeout is sent back again; repeat this process till the packet reaches the destination. In this way, each ICMP TTL timeout source address is recorded. As the result, the path from the originating host to the destination is identified.

You can perform the following actions in the Test Tools page:

• Type a domain name into the DNS Query textbox, then click Test to check the DNS working status of the device.
• Type an IP address into the Ping textbox, then click Test to check the network connecting status.
• Type an IP address or a domain name in the Traceroute textbox, then click Test to check gateways the packet has traversed.
