ACE Name, Marking Rule, Policing, and Filtering Syntax
The ACE command syntax is organized as follows:
ACL_command
ACL_type_and_name
marking_rule
policing_rule
filtering
For example, in an IP ACE, the command syntax is as follows:
set qos acl ip
acl_name
{
dscp
dscp_value
|
trust-cos
|
trust-ipprec
|
trust-dscp
} [
microflow
microflow_name
] [
aggregate
aggregate_name
]
src_ip_spec
[
precedence
precedence
|
dscp-field
dscp
]
[
before
editbuffer_index
|
modify
editbuffer_index
]
•
set qos acl ip
acl_name
—Creates a named ACL of the specified type or adds the ACE to the ACL
if it already exists. See the
“ACL Names” section on page 52-45
.
•
{
dscp
dscp_value
|
trust-cos
|
trust-ipprec
|
trust-dscp
}—Selects a marking rule. See the
“Marking Rules” section on page 52-23
.
•
[
microflow
microflow_name
] [
aggregate
aggregate_name
]—Optionally configures policing in the
ACE. See the
“Policers” section on page 52-24
.
•
src_ip_spec
[
precedence
precedence
|
dscp-field
dscp
]—The rest of the parameters, except the
editbuffer
keywords, configure filtering.

Source and Destination IP Addresses and Masks
In the IP ACEs, specify the source and destination IP addresses and masks (represented by the
src_ip_spec
and
dest_ip_spec
parameters in the following sections) in the form
ip_address
mask
. The
mask is mandatory. Use one bits, which need not be contiguous, where you want the wildcards.
Use any of the following formats for the address and mask:
•
Four-part dotted-decimal 32-bit values
•
The keyword
any
as an abbreviation for a wildcard address and wildcard mask of 0.0.0.0
255.255.255.255
•
The abbreviation
host
ip_address
for an address and wildcard mask of
ip_address
0.0.0.0
