Configuring the device IP address
2.
Use the ip address command to set the Ethernet IP address.
If you are going to use an IPv4 IP address, enter the IP address in dotted decimal notation. You should also disable DHCP and
enter a gateway address as well.
device(config)# interface Management 1/0
device(config-Management-1/0)# no ip address dhcp
device(config-Management-1/0)# ip address 10.24.85.81/20
To set up a default gateway, add an IP route in RBridge mode.
device(config-rbridge-id-10)# vrf mgmt-vrf
device (config-vrf-mgmt-vrf)# address-family ipv4 unicast
device (vrf-ipv4-unicast)# ip route 0.0.0.0/0 10.24.80.1
device (vrf-ipv4-unicast)# exit
device (config-vrf-mgmt-vrf)# exit
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
interface Management 1/0
no ip address dhcp
ip address 10.24.85.81/20
ipv6 address fd00;60;69bc;832;e61f;13ff;fe67;4b94/64
no ipv6 address autoconfig

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.
