IPv6 host address on a Layer 2 switch 5

NOTE

When confi guring an Ipv6 host address o n a Layer 2 s witch tha t has mult iple VLAN s, make su re the

configuration includes a designated management VLAN that identifies the VLAN to which the global

IP address belongs. Refer to the Brocade ICX 6650 Switch Security Configuration Guide.

Configuring a global or site-local IPv6 addresswith a manually configured interface ID

To configure a global or site-local IPv6 address with a manually-configured interface ID, such as a

system-wide address for a switch, enter a command similar to the following at the Global CONFIG

level.

Brocade(config)#ipv6 address 2001:DB8:12D:1300:240:D0FF:FE48:4000:1/64

Syntax: ipv6 address <ipv6-prefix>/<prefix-length>

You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons

as documented in RFC 2373.

You must specify the <prefix-length> parameter in decimal value. A slash mark (/) must follow the

<ipv6-prefix> parameter and precede the <prefix-length> parameter.

Configuring a link-local IPv6 address as a system-wideaddress for a switch

To enable IPv6 and automatically configure a global interface enter commands such as the

following.

Brocade(config)#ipv6 enable

This command enables IPv6 on the switch and specifies that the interface is assigned an

automatically computed link-local address.

Syntax: [no] ipv6 enable

To override a link-local address that is automatically computed for the global interface with a

manually configured address, enter a command such as the following.

Brocade(config)#ipv6 address 2001:DB8::240:D0FF:FE48:4672 link-local

This command explicitly configures the link-local address 2001:DB8::240:D0FF:FE48:4672 for the

global interface.

Syntax: ipv6 address <ipv6-address> link-local

You must specify the <ipv6-address> parameter in hexadecimal using 16-bit values between

colons as documented in RFC 2373.

The link-local keyword indicates that the router interface should use the manually configured

link-local address instead of the automatically computed link-local address.
