Example Filters For Capturing Data Traffic - Digi IX40 User Manual

Diagnostics
(config network analyzer name)> save_interval 600s
(config network analyzer name)>
d. Set the frequency with which captured events will be saved:
(config network analyzer name )> save_interval value
(config network analyzer name )>
where value is any number of weeks, days, hours, minutes, or seconds, and takes the
format number{w|d|h|m|s}.
For example, to set save_interval to ten minutes, enter either 10m or 600s:
(config network analyzer name)> save_interval 600s
(config network analyzer name)>
7. Save the configuration and apply the change
(config)> save
Configuration saved.

8. Type exit to exit the Admin CLI.
Depending on your device configuration, you may be presented with an Access selection
menu. Type quit to disconnect from the device.

Example filters for capturing data traffic

The following are examples of filters using Berkeley Packet Filter (BPF) syntax for capturing several
types of network data. See
syntax.
Example IPv4 capture filters
n Capture traffic to and from IP host 192.168.1.1:
ip host 192.168.1.1
n Capture traffic from IP host 192.168.1.1:
ip src host 192.168.1.1
n Capture traffic to IP host 192.168.1.1:
ip dst host 192.168.1.1
n Capture traffic for a particular IP protocol:
ip proto protocol
where protocol is a number in the range of 1 to 255 or one of the following keywords: icmp,
icmp6, igmp, pim, ah, esp, vrrp, udp, or tcp.
