Enter the following fields:
• Tunnel Name—Select a tunnel number.
• Tunnel Type—Displays the tunnel types: Manual, ISATAP and 6 to 4.
• Tunnel State—Select to enable the tunnel. If this tunnel is later shutdown,
this fact will be indicated in this field.
• Link Status SNMP Traps—Select to enable generating a trap when the link
status of a port is changed. If you are not interested in receiving such traps
on specific ports (for example, ISP only needs traps on ports connected to
its infrastructure, and does not need traps for the ports connected to the
user's equipment), this feature can be disabled.
• Source—Set the local (source) IPv4 address of a tunnel interface. The IPv4
address of the selected IPv4 interface is used to form part of the IPv6
address over the ISATAP tunnel interface. The IPv6 address has a 64-bit
network prefix of fe80::, with the rest of the 64-bit formed by concatenating
0000:5EFE and the IPv4 address.
Auto
- —Automatically selects the lowest IPv4 address from among all of
its configured IPv4 interfaces as the source address for packets sent on
the tunnel interface.
IPv4 Address
-
for packets sent on the tunnel interface. The local address of the tunnel
interface is not changed when the IPv4 address is moved to another
interface.
If the IPv4 address is changed, the local address of the tunnel
NOTE
interface is also changed.
- Interface —Select the interface whose IPv4 address will be used as the
source address of the tunnel.
If this interface has multiple IPv4 addresses on it, the minimum IPv4
address is used as the source address. If the minimum IPv4 address is
removed from the interface (removed at all, moved to another interface)
then the next minimum IPv4 address is chosen as the local IPv4 address
• Destination—(For manual tunnel only) Select one of the following options to
specify the destination address of the tunnel:
- Host Name—DNS name of the remote host.
- IPv4 Address—IPv4 address of the remote host.
—Specifies the IPv4 address to use as the source address
