Parameter Description
sequence sequence-number Specifies a sequence number for the ACL rule. Every
rule receives a sequence number. The sequence
number is specified by the user or is generated by the
device.
If a sequence number is not specified for the rule, a
sequence number that is 10 greater than the last
sequence number in ACL is used and this rule is
placed at the end of the list. If this is the first ACL rule
in the given ACL, a sequence number of 10 is assigned.
If the calculated sequence number exceeds the
maximum sequence number value, the ACL rule
creation fails. It is not allowed to create a rule that
duplicates an already existing one. A rule cannot be
configured with a sequence number that is already
used for another rule.
For example, if a user adds new ACL rule to ACL
without specifying a sequence number, it is placed at
the bottom of the list. By changing the sequence
number, user can move the ACL rule to a dierent
position in the ACL
[dscp dscp] Specifies the dscp value to match for the IPv6 rule.
flag [+fin | -fin] [+syn | -syn] [+rst | -rst] [+psh | -psh]
[+ack | -ack] [+urg | -urg] [established]
Specifies that the IPv6 ACL rule matches on the tcp
flags.
When +tcpflagname is specified, a match occurs if
the specified tcpflagname flag is set in the TCP
header.
When -tcpflagname is specified, a match occurs if
the specified tcpflagname flag is NOT set in the
TCP header.
When established is specified, a match occurs if the
specified either RST or ACK bits are set in the TCP
header.
Two rules are installed in hardware to when
“established” option is specified.
This option is visible only if protocol is “tcp”.
