Command Line Reference Guide

Standard IP ACL Commands
When you create an ACL without any rule and then apply it to an interface, the ACL behavior reflects an
implicit permit.
The Z9500 supports both Ingress and Egress IP ACLs.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands
sections.
deny
Configure a filter that drops IP packets meeting the filter criteria.
Z9500
Syntax
deny {source mask | any | host ip-address} [count [byte] |
[dscp value] [order] [fragments] [log [interval minutes]
[threshold-in-msgs [count]] [monitor]
To remove this filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’s
sequence number.
• Use the no deny {source [mask] | any | host ip-address}
command.
Parameters
source Enter the IP address of the network or host from which the
packets were sent.
mask Enter a network mask in /prefix format (/x) or A.B.C.D. The
mask, when specified in A.B.C.D format, may be either
contiguous or noncontiguous.
any Enter the keyword any to specify that all routes are subject
to the filter.
host ip-address Enter the keyword host then the IP address to specify a host
IP address.
count (OPTIONAL) Enter the keyword count to count packets that
the filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes that the
filter processes.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP
DSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS
priority for the ACL entry. The range is from 0 to 254 (where
0 is the highest priority and 254 is the lowest; lower-order
numbers have a higher priority). If you do not use the
keyword order, the ACLs have the lowest order by default
(255).
