Example
This example configures one permit rule for the specific address 2009:DB9:2229::79
and another rule for the addresses with the network prefix 2009:DB9:2229:5::/64.
Console(config-std-ipv6-acl)#permit host 2009:DB9:2229::79
Console(config-std-ipv6-acl)#permit 2009:DB9:2229:5::/64
Console(config-std-ipv6-acl)#

(Extended IPv6 ACL)
This command adds a rule to an Extended IPv6 ACL. The rule sets a filter condition
for packets with specific source or destination IP addresses, or next header type.
Use the no form to remove a rule.
Syntax
{permit | deny} {any | host source-ipv6-address |
source-ipv6-address[/prefix-length]}
{any | destination-ipv6-address[/prefix-length]}
[dscp dscp] [next-header next-header]
[time-range time-range-name]

[dscp dscp] [next-header next-header]
any – Any IP address (an abbreviation for the IPv6 prefix ::/0).
host – Keyword followed by a specific source IP address.
source-ipv6-address - An IPv6 source address or network class. The address
must be formatted according to RFC 2373 “IPv6 Addressing Architecture,”
using 8 colon-separated 16-bit hexadecimal values. One double colon may
be used in the address to indicate the appropriate number of zeros
required to fill the undefined fields.
destination-ipv6-address - An IPv6 destination address or network class. The
address must be formatted according to RFC 2373 “IPv6 Addressing
Architecture,” using 8 colon-separated 16-bit hexadecimal values. One
double colon may be used in the address to indicate the appropriate
number of zeros required to fill the undefined fields. (The switch only
checks the first 128 bits of the destination address.)
prefix-length - A decimal value indicating how many contiguous bits (from
the left) of the address comprise the prefix; i.e., the network portion of the
address. (Range: 0-128 for source prefix, 0-8 for destination prefix)
dscp – DSCP traffic class. (Range: 0-63)
