FDDI TCP/IP Attachment Information
Table 21 lists all con®guration items, what each item is used for, and the allowable value options for each item. The
Table 21. FDDI TCP/IP Attachment Items
Con®guration Item | Description | Value Options |
|
|
|
FDDI TCP/IP | Speci®es if the FDDI adapter is installed. | Yes or No |
Installed |
|
|
|
|
|
TCP Port | Speci®es the TCP socket address of the attachment. | 5001 to 65536. |
| Notes: |
|
| 1. Only one address is required for operating a simplex |
|
| system. |
|
| 2. If your installation runs in dual simplex and duplex |
|
| mode, specify the same TCP Port value for duplex |
|
| mode as you do for Printer 1 in dual simplex mode. |
|
| (IBM recommends using the default value of 5001.) |
|
| Also, make sure you specify a unique value for |
|
| Printer 2 in simplex mode; Printer 1 and Printer 2 |
|
| cannot use the same value. (If you use the default |
|
| value of 5001, for Printer 1, IBM recommends using |
|
| 5002 as the value for Printer 2.) |
|
| 3. The TCP Port numbers speci®ed in the printer |
|
| con®guration must match the PORT numbers |
|
| assigned in the host PSF system. |
|
| 4. Because Printer 1 in a dual simplex system and the |
|
| complete system in duplex system share a common |
|
| port number, operational procedures must be de®ned |
|
| to distinguish between duplex and dual simplex |
|
| printing. The easiest way to manage this is to assign |
|
| separate queues for duplex versus dual simplex |
|
| output (for PSF/2 and PSF/6000), and to assign at |
|
| least a unique job class for duplex jobs (for S/390 host |
|
| PSF systems). |
|
IP Address | Speci®es the Internet protocol (IP) address of the printer | X.X.X.X where X ≤ 255. |
| in dotted decimal format. Get this value from your LAN |
|
| administrator. This value must match the IP address |
|
| value in the host PSF con®guration. |
|
| This value is unique to a duplex system, and is the same |
|
| regardless of whether the printer is in duplex or |
|
|
| |
Subnet Mask | Speci®es the mask that identi®es the local subnet in | X.X.X.X where X ≤ 255 |
| dotted decimal format. Get this value from your LAN |
|
| administrator. If you do not have a local subnet, leave |
|
| this ®eld blank. |
|
Default Gateway | Speci®es the IP address of the default gateway in dotted | X.X.X.X where X ≤ 255 |
Address | decimal format. Get this value from your LAN |
|
| administrator. |
|
|
|
|
MTU Size | Speci®es the Maximum Transmission Unit (MTU) ± | 256 to 4352 |
| maximum allowable length of IP packets. |
|
|
|
|
Hardware address | Speci®es the FDDI adapter ROM address. | This address cannot be changed. |
