Multiple lter parameters can be specied in a single lteraddcommand. Packets must satisfy all of the lter
parameters to be selected; in other words, the lter parameters have a logical AND connection.

dened to select all IPv4 TCP packets from Network Port 5 with a source IP address of 192.186.10.0; packets
matching the lter are copied to Monitor Port 1.
Enter 2. ltercommit. The lter is activated.

Logical AND lter connectionFigure 28:
A logical OR connection can be made between lters by specifying multiple lters with the same Network and Monitor
port lists.
To select all packets which are either TCP or UDP protocol:
Enter 1. lteraddin_ports=n1.5ip_proto=6action=redirredir_ports=m.1. A lter has been dened to select all IPv4
TCP packets from Network Port 5 and copy them to Monitor Port 1.
Enter 2. lteraddin_ports=n1.5ip_proto=17action=redirredir_ports=m.1. Another lter has been dened to
select all IPv4 UDP packets from Network Port 5 and copy them to Monitor Port 1.
Enter 3. ltercommit. The lters are activated.
