Parameters

deny ip
[<source-IP/Mask>|any|ho
st
<IP>][<dest-IP/Mask>|any|
host <IP>] {log}
{rule-precedence
<1-5000>}

Use with a deny command to reject IP packets

deny – Sets the action type on an ACL

ip – Specifies an IP (to match to a protocol)

<source-ip/mask>|any|host <IP> – The keyword
<source-IP> is the source IP address of the network or host
in dotted decimal format. The <Mask> is the network mask.
For example, 10.1.1.10/24 indicates the first 24 bits of the
source IP is used for matching.

any – any is an abbreviation for a source IP of 0.0.0.0 and
source-mask bits equal to 0

hosthost is an abbreviation for the exact source <ip>
(A.B.C.D format) and source-mask bits equal to 32

<dest-IP/Mask>|any|host <IP> – Defines the destination
host IP address or destination network address.

log – Generates log messages when the packet coming from
the interface matches an ACL entry. Log messages are
generated only for router ACLs.

rule-precedence <1-5000> – Defines an integer value
between 1-5000. This value sets the rule precedence in the
ACL.

deny icmp
[<source-IP/Mask>|any|ho
st <IP>]
[<dest-IP/Mask>|any|host
<IP>] {<ICMP-type>
{<ICMP-code>}} {log}
{rule-precedence
<1-5000>}

Use with the deny command to reject ICMP packets

deny – Rejects ICMP packets

icmp – Specifies ICMP as the protocol

[<source-ip/mask>|any|host <IP>] – The source
<source-IP> is the source IP address of the network or host
(in dotted decimal format). The <mask> is the network mask.
For example, 10.1.1.10/24 indicates the first 24 bits of the
source IP is used for matching.

any – any is an abbreviation for a source IP of 0.0.0.0 and
source-mask bits equal to 0

host – host is an abbreviation for exact source (A.B.C.D) and
source-mask bits equal to 32

[<dest-IP/Mask>|any|host <IP>] – Defines the destination
host IP address or destination network address

<ICMP-type> {<ICMP-code>} – Sets the ICMP type value
<ICMP-type> from 0 to 255, and is valid only for ICMP. The
ICMP code value <ICMP-code> is from 0 to 255, and is valid
only for protocol type icmp.

log – Generates log messages when the packet coming from
the interface matches the ACL entry. Log messages are
generated only for router ACLs.

rule-precedence <1-5000> – Optional. Defines an integer
value between 1-5000. This value sets the rule precedence
in the ACL.
