description
Note that:
You will fail to create or modify a rule if its permit/deny statement is exactly the
same as another rule. In addition, if the ACL match order is set to auto rather than
config, you cannot modify ACL rules.
You may use the display acl command to verify rules configured in an ACL. If the
match order for this ACL is auto, rules are displayed in the depth-first match order
rather than by rule number.
Use the command...

Chapter 2 IPv4 ACL Configuration
Remarks
––
Required
The default match order is
config.
If you specify a name for an
IPv4 ACL when creating the
ACL, you can use the acl
name acl-name command to
enter the view of the ACL later.
Required
To create multiple rules,
repeat this step.
Note that if the ACL is to be
referenced by a QoS policy for
traffic classification, the
logging and reflective
keywords are not supported
and the operator argument
cannot be:
neq, if the policy is for the
inbound traffic,
gt, lt, neq or range, if the
policy is for the outbound
traffic.
Optional
The default step is 5.
