Ipv6 Address Eui-64 - Edge-Core ECS4120-28F Reference Manual

ipv6 address eui-64

(The link-local address is made with an address prefix of FE80 and a host
portion based the switch's MAC address in modified EUI-64 format.
◆
If a duplicate address is detected, a warning message is sent to the console.
◆
When DHCPv6 is restarted, the switch may attempt to acquire an IP address
prefix through stateful address autoconfiguration. If the router advertisements
have the "other stateful configuration" flag set, the switch may also attempt to
acquire other non-address configuration information (such as a default
gateway) from a DHCPv6 server when DHCPv6 is restarted.
Example
This example assigns a dynamic global unicast address to the switch.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address autoconfig
Console(config-if)#end
Console#show ipv6 interface

This command configures an IPv6 address for an interface using an EUI-64 interface
ID in the low order 64 bits and enables IPv6 on the interface. Use the no form
without any arguments to remove all manually configured IPv6 addresses from the
interface. Use the no form with a specific address to remove it from the interface.
