tion
vpn-instance
vpn-instance-name
Applies the rule to a VPN
instance.
The vpn-instance-name argument is a case-sensitive string
of 1 to 31 characters.
If you do not specify a VPN instance, the rule applies only
to non-VPN packets.
If the protocol argument is tcp (6) or udp (17), set the parameters shown in Table 13.
Table 13 TCP/UDP-specific parameters for IPv6 advanced ACL rules
Parameters Function Descri
p
tion
source-port
operator port1
[ port2 ]
Specifies one or more
UDP or TCP source
ports.
The operator argument can be lt (lower than), gt (greater than), eq
(equal to), neq (not equal to), or range (inclusive range).
The port1 and port2 arguments are TCP or UDP port numbers in the
range of 0 to 65535. port2 is needed only when the operator
argument is range.
TCP port numbers can be represented as: chargen (19), bgp (179),
cmd (514), daytime (13), discard (9), domain (53), echo (7), exec
(512), finger (79), ftp (21), ftp-data (20), gopher (70), hostname
(101), irc (194), klogin (543), kshell (544), login (513), lpd (515),
nntp (119), pop2 (109), pop3 (110), smtp (25), sunrpc (111),
tacacs (49), talk (517), telnet (23), time (37), uucp (540), whois
(43), and www (80).
UDP port numbers can be represented as: biff (512), bootpc
(68),
bootps (67), discard (9), dns (53), dnsix (90), echo (7), mobilip-ag
(434), mobilip-mn (435), nameserver (42), netbios-dgm (138),
netbios-ns (137), netbios-ssn (139), ntp (123), rip (520), snmp
(161), snmptrap (162), sunrpc (111), syslog (514), tacacs-ds (65),
talk (517), tftp (69), time (37), who (513), and xdmcp (177).
destination-port
operator port1
[ port2 ]
Specifies one or more
UDP or TCP
destination ports.

| fin fin-value |
psh psh-value |
rst rst-value |
syn syn-value |
urg urg-value }
*
Specifies one or more
TCP flags, including
ACK, FIN, PSH, RST,
SYN, and URG.
Parameters specific to TCP.
The value for each argument can be 0 (flag bit not set) or 1 (flag bit
set).
The TCP flags in a rule are ANDed. For example, a rule configured
with ack 0 psh 1 matches packets that have the ACK flag bit not set
and the PSH flag bit set.
established
Specifies the flags for
indicating the
established status of a
TCP connection.
Parameter specific to TCP.
The rule matches TCP connection packets with the ACK or RST flag
bit set.
If the protocol argument is icmpv6 (58), set the parameters shown in Table 14.
Table 14 ICMPv6-specific parameters for IPv6 advanced ACL rules
Parameters Function Descri
p
tion
icmp6-type { icmp6-type
icmp6-code |
icmp6-message }
Specifies the ICMPv6
message type and
code.
The icmp6-type argument is in the range of 0 to 255.
The icmp6-code argument is in the range of 0 to 255.
The icmp6-message argument specifies a message name.
Supported ICMP message names and their corresponding
type and code values are listed in Table 15.
