Boot Error Report

If an error occurs,a Rem ote Access Concentratorboot error report is

generated only if the Remote Access Concentrator has opened the boot

file. The report is displayed using the following format:

BOOT ERROR REPORT (for BFS files only)

Boot attempt from host nn.nn.nn.nn:

Errors from Last Open Request:

0 ARP errors 0 ERPC layer errors 0 Aborts rx’d

Errors from Last Read Request:

0 Msgs w/ wrong size 0 ERPC layer errors 0 Aborts rxd

Errors from Last ERPC Layer Invocation:

0 H/W errors 1 Msgs from wrong host 0 Rsp T/O’s 0 Msgs of wrong type

TFTP error reportingcomplies with the standard, predefined

TFTP error codes.

The Remote Access Concentrator generatesa boot error report for the

Internetaddress fromwhich ittried, andfailed, toboot. Tab le 4 -4 contains

a description of the Errorsfrom the Last Read Request; and Ta ble 4- 3

contains a description of the Errors from Last ERPC Layer Invocation.

The error count pinpoints the error that caused the boot failure. For

example,if the boot failed during a Read Request due to excessive

Expedited Remote ProcedureCall (ERPC) layer errors, the Errors from

Last ERPC Layer Invocation lists only errors that occurred during the

failedRead Request (see Tabl e 4-3). The report does not list errors that

occurred during any other Read Request (see Tabl e 4-4) or during the

OpenRequest (see Tab le 4-5 ).

The Open Request and the Read Request layers communicatewith the

block fileserver (BFS) on the host. The ERPC layer resides below the

Open Requestand the Read Request layers. It is responsible for sending

agiven message to a specific host UDP port, andf orreceiving the correct

response to that message from the port.
