Parameter xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Description Interface Name This is the IPv6 tunnel interface name. Interface Admin Enable or disable IP tunneling. State Mode Select from Manual, 6to4, or ISATAP. Manual is used to configure an existing IPv6 tunnel as an IPv6 manual tunnel on the Switch. If this tunnel has previously been configured in another mode, the tunnel's information will still exist in the database. However, whether the tunnel's former information is invalid or not, will depend on the current mode. IPv6 Manual tunnels are simple point-to-point tunnels that can be used within a site or between sites 6to4 is used to configure an existing IPv6 tunnel as an IPv6 6to4 tunnel on the Switch. If this tunnel has previously been configured in another mode, the tunnel's information will still exist in the database. However, whether the tunnel's former information is invalid or not will depend on the current mode. A maximum of one IPv6 6to4 tunnel can exist on the system. IPv6 6to4 tunnels are point-to-multipoint tunnels that can be used to connect isolated IPv6 sites. Each IPv6 site has at least one connection to a shared IPv4 network and this IPv4 network could be the global Internet or a corporate backbone. The key requirement is that each site has a globally unique IPv4 address, which is used to construct a 48-bit globally unique 6to4 IPv6 prefix (It starts with the prefix 2002::/16). ISATAP is used to configure an existing IPv6 tunnel as an IPv6 ISATAP tunnel on the Switch. If this tunnel has previously been configured in another mode, the tunnel's information will still exist in the database. However, whether the tunnel's former information is invalid or not will depend on the current mode. IPv6 ISATAP tunnels are point-to-multipoint tunnels that can be used to connect systems within a site. An IPv6 ISATAP address is a well-defined unicast address that includes a 64-bit unicast IPv6 prefix (it can be link local or global prefixes), a 32-bit value 0000:5EFE and a 32-bit tunnel source IPv4 address. IPv6 Address/Prefix Length Enter the IPv6 address assigned to this IPv6 tunnel interface. IPv6 processing would be enabled on this IPv6 tunnel interface when an IPv6 address is configured. This IPv6 address is not connected with tunnel source or destination IPv4 address. Source IP Address Enter the source IPv4 address of this IPv6 tunnel interface. It is used as the source address for packets in this IPv6 tunnel. Destination IP Address Enter the destination IPv4 address of this IPv6 tunnel interface. It is used as the destination address for packets in this IPv6 tunnel. It is not required for 6to4 and ISATAP tunnels. Click Apply to implement changes made. 193
