Perform a Traffic Capture

STEP 1 From the LSM, select Network > Tools. On the Tools page, click the Traffic Capture tab.

STEP 2 On the Traffic Capture page, click Create Capture File.

STEP 3 On the Create Traffic Capture page, specify the Capture File Details:

STEP A If required, change the settings for the Max File Size (upper limit is 10000000) and the Max Packets (upper limit is 10000).

STEP B Select the security Zone Pair on which you want to capture traffic.

STEP 4 Optionally, to further specify which packets to include in the capture, enter IP protocol and source/destination addresses parameters in the Capture Filter table.

STEP 5 Click Start Capture.

Ping

Use the Ping feature to send Ping requests to test whether devices on an IP network are accessible and functioning correctly.

Ping can help diagnose connectivity problems such as a failed network device between the device and the web server being accessed, or to help diagnose DNS setup problems. For example, if the device cannot access www.mycompany.com, enter www.mycompany.com in the Host IP field and click Start Ping. If the IP address for the Host appears in the Output table, the DNS server can be contacted and is working correctly. The problem is therefore a connectivity issue between the device and the original web server.

Note Ensure that the policies configured on the device allow the security zone to send Ping (ICMP) requests. A firewall rule allowing Ping requests between zones allows the request to be sent to the destination zone and the response to be allowed back to the source zone.
