Advanced Traffic Management Guide K/KA/KB.15.15

source-address
destination-address
Defines the source IP address (SA) and destination IP
address (DA) that a packet must contain to match a
match/ignore statement in an IPv4 or IPv6 traffic class.
Both the source and destination address parameters
are required entries in a match/ignore statement.
Valid values for source-address and
destination-address are as follows:
• any: Matches IPv4 or IPv6 packets from, or
destined to, any SA or DA.
• host [ SA | DA ]: Matches only packets from
a specified IPv4 or IPv6 host address. Use this
match criterion when you want to match IP packets
from only one SA/DA.
• SAv4 mask | DAv4 mask: Matches packets
received from, or destined to, a subnet or a group
of IP4 addresses defined by the IPv4 mask. Enter
an IPv4 mask in dotted-decimal format for an IPv4
address (for example, 10.28.31.1 0.0.0.255).
NOTE: An IPv6 address and mask are not
supported as SAv6 mask and DAv6 mask match
criteria.
• SAv4/mask-length | DAv4/mask-length:
Matches packets received from, or destined to, an
IPv4 subnet or a group of IPv4 addresses defined
by the mask length. Enter the mask length for an
IPv4 SA or DA mask in CIDR format by using the
number of significant bits. (for example,
10.28.31.3/24).
An IPv4 mask-length is applied to an SA or DA in
a match/ignore statement to define which bits in
a packet's SA/DA must exactly match the specified
SA/DA and which bits need not match. For
example, 10.28.31.3/24 means that the leftmost
24 bits in an IPv4 source or destination address
in a packet header must match the same bit set in
the specified IPv4 address (in this case,
10.28.3.3).
An IPv4 mask-length is applied from right to left,
starting from the rightmost bits. For example,
10.10.10.1/24 and 10.10.10.1 0.0.0.255 both
match IPv4 addresses in the range 10.10.10.(1
to 255).
NOTE: Specifying a group of non-contiguous IP
source addresses may require more than one
match/ignore statement.
• SAv6/prefix-length |
DAv6/prefix-length: Matches packets
received from, or destined to, an IPv6 subnet or a
group of IPv6 addresses defined by the prefix
