Enable or disable IPv6 By default: ● IPv6 forwarding is enabled on physical Ethernet interfaces, VLANs, and port groups. IPv6 forwarding is disabled only when you enable IPv6 address autoconfiguration on an interface and set it in host mode using the ipv6 address autoconfig command. ● IPv6 forwarding is permanently disabled on the management Ethernet interface so that it remains in Host mode and does not operate as a router regardless of the ipv6 address autoconfig setting. If necessary, you can manually disable IPv6 processing on an interface so that the configured IPv6 addresses do not take effect. The IPv6 addresses take effect again when you re-enable IPv6. If you disable IPv6 and configure a Layer (L2) interface in Layer (L3) mode, IPv6 is not automatically re-enabled on the interface. You must manually re-enable it. A link-local address automatically generates when you re-enable IPv6 on an interface with the ipv6 enable command.

IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by colons: x:x:x:x:x:x:x:x. 2001:0db8:0000:0000:0000:0000:1428:57a Leading zeros in each field are optional. You can also use two colons (::) to represent successive hexadecimal fields of zeros, but you can use this short version only one time in each address: 2001:db8::1428:57ab 718 Layer 3
