• IPv6 Gateway
Input the gateway IPv6 address of the target port.
The following IPv6 addresses can be used; "link local address", "global address", "unique local
address", and "6to4 address". Refer to "Available IPv6 Address" (page 757)
for details. Note that the
current setting is displayed by an abbreviation.
"IPv6 Gateway" can be directly input or created automatically.
Click the [Discovery] button to display the [Select IPv6 Gateway] screen. Up to three "IPv6 Gateway"
can be obtained. Select "IPv6 Gateway" and click the [OK] button. The selected IPv6 address is
specified in the entry field.
The following input condition applies:
- xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
xxxx: 0 - ffff (FFFF) (hexadecimal, alphanumeric characters)
Refer to "IPv6 Address Notation" (page 378)
for details.
• TCP Port No.
Input the TCP port number of the target port between 0 and 28671.
Click the [Default] button to set the default TCP port number.
• TCP Window Scale
Select the TCP Window scale of the target port between 0 and 14.
"TCP Window Scale" is a parameter that is used to specify the TCP window size. When the I/O load is
high, the expected performance may not be achieved even if "0" or "1" is specified for TCP Window
Scale. Even if "8" or higher is specified, the ETERNUS DX Disk storage system performs as though "7"
is specified for TCP Window Scale.
Specify the "TCP Window Scale" in powers of two (when the value is n-th to the power of two, "n"
indicates the "TCP Window Scale"). The relationship between the setting value and the TCP Window
size is as follows:
Do not change the TCP port number from 3260 (default value). REC can only be performed when
"TCP Port No." is "3260".
