If you are going to use an IPv6 address, enter the network information in semicolon-separated
notation as prompted after the 

ipv6 address

 operand.

device(config)# interface Management 1/0

device(config-Management-1/0)# no ip address dhcp

device(config-Management-1/0)# ipv6 address \

fd00;60;69bc;832;e61f;13ff;fe67;4b94/64

3. To display the configuration, use the 

show running-config interface Management 

command.

device# show running-config interface Management 1/0

Stateless IPv6 autoconfiguration

IPv6 allows assignment of multiple IP addresses to each network interface. Each interface is
configured with a link local address in almost all cases, but this address is only accessible from other
hosts on the same network. To provide for wider accessibility, interfaces are typically configured with
at least one additional global scope IPv6 address. IPv6 autoconfiguration allows more IPv6 addresses,
the number of which is dependent on the number of routers serving the local network and the number
of prefixes they advertise.

When IPv6 autoconfiguration is enabled, the platform will engage in stateless IPv6 autoconfiguration.
When IPv6 autoconfiguration is disabled, the platform will relinquish usage of any autoconfigured IPv6
addresses that it may have acquired while IPv6 autoconfiguration was enabled. This same enabled or
disabled state also enables or disables the usage of a link local address for each managed entity
(though a link local address will continue to be generated for each device) because those link local
addresses are required for router discovery.

The enabled or disabled state of autoconfiguration does not affect any static IPv6 addresses that may
have been configured. Stateless IPv6 autoconfiguration and static IPv6 addresses can coexist.

Setting stateless IPv6 autoconfiguration

To configure stateless IPv6 autoconfiguration, complete the following steps.

1. Enter the 

configure terminal

 command to enter global configuration mode.

2. Take the appropriate action based on whether you want to enable or disable IPv6 autoconfiguration:

• Enter the 

ipv6 address autoconfig

 command to enable IPv6 autoconfiguration for all managed

entities on the target platform.

• Enter the 

no ipv6 address autoconfig

 command to disable IPv6 autoconfiguration for all

managed entities on the target platform.

Changing the RBridge ID

If you are planning to have more than one device in a fabric, each device must have a unique RBridge
ID. The default RBridge ID for the device is 1. Use the 

vcs rbridge-id

 

rbridge-id

 command while in

privileged executive mode (device# prompt) to change the default RBridge ID. Observe the following
notes and recommendations when using this command:
