◆
When you create a new ACL or enter configuration mode for an existing ACL,
use the
permit or deny command to add new rules to the bottom of the list. To
create an ACL, you must add at least one rule to the list.

To remove a rule, use the no permit or no deny command followed by the
exact text of a previously configured rule.

An ACL can contain up to 96 rules.

any – Any source IP address.
host – Keyword followed by a specific 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.
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)
time-range-name - Name of the time range. (Range: 1-32 characters)
