Chapter 6      Security Commands

deny (IPv6)

Command Default

None

Command Modes

IPv6 ACL configuration

Command History

Usage Guidelines

A newly created IPv6 ACL contains no rules.

When the device applies an IPv6 ACL to a packet, it evaluates the packet with every rule in the ACL. 
The device enforces the first rule whose conditions are satisfied by the packet. When the conditions of 
more than one rule are satisfied, the device enforces the rule with the lowest sequence number.

This command does not require a license.

Source and Destination

You can specify the 

source

 and 

destination

 arguments in one of several ways. In each rule, the method 

you use to specify one of these arguments does not affect how you specify the other. When you configure 
a rule, use the following methods to specify the 

source

 and 

destination

 arguments:

•

IPv6 address group object—You can use an IPv6 address group object to specify a 

source

 or 

destination

 argument. Use the 

object-group ipv6 address

 command to create and change IPv6 

address group objects. The syntax is as follows:

addrgroup

 

address-group-name

The following example shows how to use an IPv6 address object group named lab-svrs-1301 to 
specify the 

destination

 argument:

switch(config-acl)# 

deny ipv6 any addrgroup lab-svrs-1301

•

Address and variable-length subnet mask—You can use an IPv6 address followed by a 
variable-length subnet mask (VLSM) to specify a host or a network as a source or destination. The 
syntax is as follows:

established

(TCP only; Optional) Specifies that the rule matches only packets that 
belong to an established TCP connection. The device considers TCP packets 
with the ACK or RST bits set to belong to an established connection.

flags

(TCP only; Optional) Rule matches only packets that have specific TCP 
control bit flags set. The value of the 

flags

 argument must be one or more of 

the following keywords:

•

ack

•

fin

•

psh

•

rst

•

syn

•

urg

Release

Modification

4.0(1a)N1(1)

This command was introduced.
