Performing Diagnostic Tests

Diagnostic tools allows the administrator to test SRA connectivity by performing a ping, TCP connection test, DNS lookup, or Traceroute for a specific IP address or Web site. You can also perform a bandwidth test between the SRA appliance and your local computer, or do an SNMP query to display information about the appliance.

You can perform standard network diagnostic tests on the SRA appliance in the System > Diagnostics page.

To run a diagnostic test:
1
Navigate to the System > Diagnostics page.

2
In the Diagnostic Tool drop-down list, select Bandwidth Test, TCP Connection Test, DNS Lookup, Ping, Ping6, Traceroute, Traceroute6, SNMP Query, or Botnet Test.

These diagnostic tools perform the following functions:

 

Table 21. Diagnostic tools and their functions

Diagnostic Tool

Function

Bandwidth Test

Measures the upload and download speed of the network connection between your computer and the SRA appliance.

TCP Connection Test

Tests the connectivity of a port, which is specified by appending a colon and port number to the host name or IP address (e.g., 10.9.9.19:83 or www.myhost.com:83. If no port is specified, port 80 is tested.

DNS Lookup

Translates a DNS name to an IP address and vice versa.

Ping

Tests the connection to a host or IP address.

Ping6

Tests the connection to an IPv6 address or domain. Ping6 is meant for use with IPv6 addresses and networks.

Traceroute

Identifies the route and number of hops needed to connect to a host or IP address.

Traceroute6

Identifies the route and number of hops needed to connect to an IPv6 address or domain. Traceroute 6 is meant for use with IPv6 addresses and networks.

SNMP Query

Looks up SNMP information from the selected MIB. SNMP must be enabled (System > Administration page) before a query can be performed. In the SNMP MIB drop-down list, select the MIB for which to display the values. The SNWL-SSLVPN-MIB is the SRA specific MIB that shows device statistics and licensing information. The SNWL-COMMON-MIB is a file common to all Dell SonicWALL products and shows product name, serial, firmware, ROM version, and asset number (user defined). The rest of the MIBs are standard SNMP MIBs including SNMPv2-MIB and All SNMP MIB-2, or you can select ALL MIBs.

Botnet Test

Identifies whether an IP address is a Botnet IP address.
