Boot Error Report - Cabletron Systems CSMIM2-16 Installation Manual

Boot Error Report

If an error occurs, a boot error report is generated only if the CSMIM2 has
opened the boot file. The report uses 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
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
0 Msgs of wrong type
TFTP error reporting complies with the standard, pre-defined
NOTE
TFTP error codes.
The CSMIM2 generates a boot error report for the Internet address from
which it tried, and failed, to boot. Table 4-5 describes the Errors from
Last Open Request; Table 4-6 describes the Errors from Last Read
Request; and Table 4-7 describes 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 Procedure Call (ERPC) layer errors, the Errors from
Last ERPC Layer Invocation lists only errors that occurred during the
failed Read Request. The report does not list errors that occurred during
any other Read Request or during the Open Request.
The Open Request and the Read Request layers communicate with the
block file server (BFS) on the host. The ERPC layer resides below the
Open Request and the Read Request layers. It is responsible for sending a
given message to a specific host UDP port, and for receiving the correct
response to that message from the port.
