IPv6 management features
As shown in Figure 33, the IPv6 network prefix is composed of the left-most bits of the address. As
with an IPv4 address, you can specify the IPv6 prefix using the <prefix>/<prefix-length> format,
where the following applies.
The <prefix> parameter is specified as 16-bit hexadecimal values separated by a colon.
The <prefix-length> parameter is specified as a decimal value that indicates the left-most bits of
the IPv6 address.
The following is an example of an IPv6 prefix.
2001:FF08:49EA:D088::/64
Enabling and disabling IPv6
IPv6 is enabled by default for Brocade devices that support it. If desired, you can disable IPv6 on a
global basis on an device by entering the following command at the Global CONFIG level of the CLI.
Brocade(config)#no ipv6 enable
Syntax: no ipv6 enable
To re-enable IPv6 after it has been disabled, enter the ipv6 enable command.
IPv6 management features
This section describes the CLI management commands that are available to FastIron devices that
support IPv6.
IPv6 management ACLs
When you enter the ipv6 access-list command, the Brocade device enters the IPv6 Access List
configuration level, where you can access several commands for configuring IPv6 ACL entries. After
configuring the ACL entries, you can apply them to network management access features such as
Telnet, SSH, Web, and SNMP.
NOTE
Unlike IPv4, there is no distinction between standard and extended ACLs in IPv6.
Example
Brocade(config)#ipv6 access-list netw
Brocade(config-ipv6-access-list-netw)#
Syntax: [no] ipv6 access-list <ACL name>
The <ACL name> variable specifies a name for the IPv6 ACL. An IPv6 ACL name cannot start with a
numeral, for example, 1access. Also, an IPv4 ACL and an IPv6 ACL cannot share the same name.
IPv6 Web management using HTTP and HTTPS
When you have an IPv6 management station connected to a switch with an IPv6 address applied to
the management port, you can manage the switch from a Web browser by entering http://[<ipv6
address>] or
https://[<ipv6 address>] in the browser address field.
