length. Enter the prefix length for an IPv6 SA/DA
in CIDR format by using the number of significant
bits; for example:
2001:db8:2620:212::01b4/64.
An IPv6 prefix-length is applied to an SA/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, 2001:db8:2620:212::01b4/64 means
that the leftmost 64 bits in a 128-bit IPv6 source
or destination address in a packet header must
match the same bit set in the specified IPv6 address
(in this case, 2001:db8:2620:212::01b4).
An IPv6 prefix-length is applied from left to right,
starting from the leftmost bits. For example,
2001:db8::0001: 2620:a03:e102:127/64 and
2001:db8::1: 244:17ff:feb6:d37d/64 both match
IPv6 addresses with a network prefix of
2001:db8:0000:0001.
ip-dscp codepoint (Optional) Matches the six-bit DSCP codepoint DSCP
codepoint in IPv4 or IPv6 packets to further define
match criteria. Valid values for codepoint are one
of the following:
• Numeric equivalent of a binary DSCP bit set from
0 (low priority) to 63 (high priority)
• ASCII standard name for a binary DSCP bit set:
af11 (001010) af42 (100100)
af12 (001100) af43 (100110)
af13 (001110) ef
(101110) af21 (010010) cs1 (001000)=
precedence 1
af22 (010100) cs2 (010000)=
precedence 2
af23 (010110) cs3 (011000)=
precedence 3
af31 (011010) cs4 (100000)=
precedence 4
af32 (011100) cs5 (101000)=
precedence 5
af33 (011110) cs6 (110000)=
precedence 6
af41 (100010) cs7 (111000) =
precedence 7
default (000000)
To display a list of valid codepoint entries when
you enter ip-dscp in a match/ignore statement,
enter ?.
The DSCP codepoints are the leftmost six bits of
the ToS/Traffic Class byte.
precedence precedence-value (Optional) Matches the three-bit IP precedence value
in IPv4 or IPv6 packets to further define match criteria.
