IPv6 Interfaces

© Copyright Lenovo 2015
Each IPv6 interface supports multiple IPv6 addresses. You can manually configure
up to two IPv6 addresses for each interface, or you can allow the switch to use
stateless autoconfiguration. By default, the switch automatically configures the
IPv6 address of its management interface.
You can manually configure two IPv6 addresses for each interface, as follows:
Initial IPv6 address is a global unicast or anycast address .

CN 4093(config)# interface ip <interface number>
CN 4093(config-ip-if)# ipv6 address <IPv6 address>
Note that you cannot configure both addresses as anycast. If you configure an
anycast address on the interface you must also configure a global unicast
address on that interface.
 Second IPv6 address can be a unicast or anycast address .
CN 4093(config-ip-if)# ipv6 secaddr6 <IPv6 address>
CN 4093(config-ip-if)# exit
You cannot configure an IPv4 address on an IPv6 management interface. Each
interface can be configured with only one address type: either IPv4 or IPv6, but not
both. When changing between IPv4 and IPv6 address formats, the prior address
settings for the interface are discarded.
Each IPv6 interface can belong to only one VLAN. Each VLAN can support only
one IPv6 interface. Each VLAN can support multiple IPv4 interfaces.
Interface 125/126 is reserved for IPv6 host support. This interface is included in
management VLAN 4095. Use the following commands to configure the IPv6
gateway:
CN 4093(config)# ip gateway6 1 address <IPv6 address>
CN 4093(config)# ip gateway6 1 enable
IPv6 gateway 1 is reserved for IPv6 data interfaces. IPv6 gateway 3 and 4 are the
default IPv6 management gateways.
