•{
deny | permit
}–Specifies whether the IP ACL rule
permits or denies the matching traffic.
•{
ipv6-protocol
|
number
|
every
}—Specifies the protocol
to match for the IP ACL rule.
– IPv4 protocols:
icmpv6, ipv6, tcp and udp
–
Every
: Match any protocol (don’t care)
•
source-ipv6-prefix
/prefixlength |
any | host
src-ipv6-
address
—Specifies a source IP address and netmask to
match for the IP ACL rule.
– For IPv6 ACLs, “any” implies a 0::/128 prefix and a
mask of all ones.
– Specifying “host X::X” implies a prefix length as “/128”
and a mask of 0::/128.

} | {eq |
neq | lt | gt} {
portkey
|
0-65535
}]—Specifies the layer 4
destination port match condition for the IP/TCp/UDP
ACL rule. A destination port number, which ranges from
0-65535, can be entered, or a
portkey
, which can be one of
the following keywords: bgp, domain, echo, ftp, ftp-data,
http, ntp, pop2, pop3, rip, smtp, snmp, telnet, tftp,
telnet, time, who and www. Each of these keywords
translates into its equivalent destination port number.
– When “range” is specified, IPv6 ACL rule matches only
if the layer 4 port number falls within the specified
portrange. The
startport
and
endport
parameters
identify the first and last ports that are part of the port
range. They have values from 0 to 65535. The ending
port must have a value equal or greater than the
starting port. The starting port, ending port, and all
ports in between will be part of the layer 4 port range.
– When “eq” is specified, IPv6 ACL rule matches only if
the layer 4 port number is equal to the specified port
number or portkey.
– When “lt” is specified, IPv6 ACL rule matches if the
layer 4 destination port number is less than the
specified port number or portkey. It is equivalent to
specifying the range as 0 to <specified port number –
1>.
