Description
Filter IPv6 packets by IP address.
You may give either a single specification, to find packets where either the source or the destination
address matches, or separate specifications for source and/or destination address. The following formats
are recognized in each case:
2000:abcd:0:0:0:0:77:88 – A single address
2000:abcd::77:88 – A single address (eliding a single run of zero segments)
2000:abcd::77:88-99 – A range address (inclusive)
2000::* – A wildcard (here: 2000::0-ffff )
::ffff:0:0/96 – Prefix (any address starting 0:0:0:0:0:ffff )
2000::1, 2000::3 – Multiple addresses
Ranges and wildcards may be used in any segment(s).
Multiple addresses may each use either ranges and wildcards or prefix notation.
Filter IP traffic by its internet protocol, for example whether it uses a transport protocol such as TCP,
UDP or ICMPv4.
If you specify TCP, UDP or both, you may further filter by the corresponding layer 4 ports.
Filter traffic by the DSCP specified in the packet header. Separate multiple DSCP numbers with commas.
Filter TCP or UDP packets by port number.
You may give either a single specification, to find packets where either the source or the destination port
matches, or separate specifications for source and/or destination port.
The following formats are recognized in each case:
10 – A single port
10-20 – A range (inclusive)
0/1 – A value/mask pair (here: all even ports)
10,15 – Multiple ports
Multiple ports may each use a range.
Common examples for TCP include:
80, 8080, 443 – HTTP/HTTPS
25 – SMTP
20-21, 989-990 – FTP/FTPS
22 – SSH
23 – Telnet
