Defining IPv6 Addresses
To assign an IPv6 address to an IPv6 Interface:
- Click Administration > Management Interface (Layer 2) > IPv6 Addresses
The IPv6 Addresses page opens.
- Select an interface name, and click Go. The interface is displayed in the IPv6 Address Table.
- Click Add. The Add IPv6 Address page opens.
- Enter values for the fields.
- IPv6 Interface--Displays the interface where the address is automatically completed, based on the filter.
- IPv6 Address Type--Select Link Local or Global as the type of IPv6 address to add.
- Link Local--The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.
- Global--The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other networks.
- IPv6 Address--The switch supports one IPv6 interface. In addition to the default link local and Multicast addresses, the device also automatically adds global addresses to the interface based on the router advertisements it receives. The device supports a maximum of 128 addresses at the interface. Each address must be a valid IPv6 address that is specified in hexadecimal format by using 16-bit values separated by colons.
NOTE You cannot configure an IPv6 addresses directly on a ISATAP tunnel interface.
- Prefix Length--The length of the Global IPv6 prefix is a value from 0-128 indicating the number of the high-order contiguous bits of the address comprise the prefix (the network portion of the address).
- EUI-64--Select to use the EUI-64 parameter to identify the interface ID portion of the Global IPv6 address by using the EUI-64 format based on a device MAC address.
- Click Apply. The Running Configuration file is updated.
