IP Packet Filters / Discarded IP Packet Filters
TCP/UDP Ports
This parameter filters out TCP or UDP packets with particular source or destination port
numbers. The format of this parameter is a comma-separated list of port numbers. For example,
suppose you want to exclude the capture of Telnet and HTTP traffic that would otherwise
swamp the data of interest. To do this, enter 23,80 for this parameter. Conversely, to capture
traffic on a specific source or destination port only, use a tilde () symbol before the list of ports.
For example, to only capture Telnet and SSH packets, enter 22,23 for this parameter.
IP Protocols
Filters out IP packets with particular IP protocol numbers. The format of this parameter is a
comma-separated list of protocol numbers. For example, suppose you want to exclude the
capture of TCP traffic that would otherwise swamp the data of interest. To do this, enter 6 for
this parameter. Conversely, to capture traffic with a specific IP protocol number only, use a tilde
() symbol before the list of protocol numbers. For example, to only capture UDP traffic, enter
17 for this parameter.
IP Addresses
Filters out IP packets with particular source or destination IP addresses. The format of this
parameter is a comma-separated list of IP addresses. For example, you may want to exclude the
capture of traffic from IP hosts 10.1.2.3 and 10.2.2.2. To do this, enter 10.1.2.3,10.2.2.2 for this
parameter. Conversely, to capture traffic to and from particular IP hosts only, use a tilde ()
symbol before the list of IP addresses. For example, to only capture packets to and from IP host
192.168.47.1, enter 192.168.47.1 for this parameter.
