| Use DLI just like you would on Ethernet.

| 258.2 | DLI -> FDDI Questions | DMEICE::PAGE | | Mon Nov 18 1991 17:01 | 18 |
| Can someone tell me the max packet size for the DLI interface
using the FDDI controller? Is it the 4.5k as specified
by other specs?
If I wanted to send certain packets using synchronous mode,
how would I go about it?
From reading the MAC chip spec, one of the first three bytes
to the chip has a flag bit to determine synchronous mode. Who
sets these bits? Are they done by the driver or by the DLI
layer?
Are there any performance reports using the DLI layer over
FDDI? I want to go class 1, type 1, if this helps.
regards,
Cal

| The size depends on the packet format you are using. All the values
are documented in the FDDI architecure, and the VMS V5.4-3 release
notes, and Chapter 6 of the IO User's Guide Pasrt II.
Assuming you are using VMS of course. However, there is no support for
synchronous frames in the VMS driver,.. so your question is fairly
irrelevant. You are working outside the architecture,.. and wil need
to write your own driver anyway,.. so you'll be specifying your own
packet size limitations and your own DLI. Unless I missed something.

| "DLI" is an Ultrix thing (it does some of the stuff outside the driver
that VMS does inside the driver, such as LLC demuxing.
You might ask Matt Thomas (mipsbx::thomas) or Chran-Ham Chang (abyss::chc).

| ULTRIX only sends async LLC PDUs. Due to a bug in ULTRIX (IP centric that it
is), you are restricted to ~4352 octets instead of 4470. (The number varies
depending on the size of the LLC info).
