The broadcast, multicast, and all protocol qualifiers cannot modify variables.
Table 32 Variable types for capture filters
Variable type Description
Represented in binary, octal,
Integer
decimal, or hexadecimal notation.
Represented by hyphenated
Integer range
integers.
Represented in dotted decimal
IPv4 address
notation.
Represented in colon hexadecimal
IPv6 address
notation.
Represented by an IPv4 network ID
IPv4 subnet
or an IPv4 address with a mask.
IPv6 network Represented by an IPv6 address
segment with a prefix length.
Description
Matches packets based on its
source or destination location (an
IP address or port number).
If you do not specify a direction
qualifier, the src or dst qualifier
applies.
Specifies the direction type.
Any other qualifiers than the
previously described qualifiers.

Examples
•
src—Matches the source IP address
field.
•
dst—Matches the destination IP address
field.
•
src or dst—Matches the source or
destination IP address field.
NOTE:
The src or dst qualifier applies if you do not
specify a direction qualifier. For example,
port 23 is equivalent to src or dst port 23.
•
host—Matches the IP address of a host.
•
net—Matches an IP subnet.
•
port—Matches a service port number.
•
portrange—Matches a service port
range.
NOTE:
The host qualifier applies if you do not
specify any type qualifier. For example, src
2.2.2.2 is equivalent to src host 2.2.2.2.
To specify an IPv6 subnet, you must specify
the net qualifier.
•
broadcast—Matches broadcast packets.
•
multicast—Matches multicast and
broadcast packets.
•
less—Matches packets that are less than
or equal to a specific size.
•
greater—Matches packets that are
greater than or equal to a specific size.
•
len—Matches the packet length.
•
vlan—Matches VLAN packets.
Examples
The port 23 expression matches traffic sent to or
from port number 23.
The portrange 100-200 expression matches traffic
sent to or from any ports in the range of 100 to 200.
The src 1.1.1.1 expression matches traffic sent
from the IPv4 host at 1.1.1.1.
The dst host 1::1 expression matches traffic sent
to the IPv6 host at 1::1.
Both of the following expressions match traffic sent
to or from the IPv4 subnet 1.1.1.0/24:
•
src 1.1.1.
•
src net 1.1.1.0/24.
The dst net 1::/64 expression matches traffic sent
to the IPv6 network 1::/64.
