The Question is:
What causes this? It happened for a period of about 15 minutes recently.
The Answer is :
DECnet host 1.140 sent a message to LOCAL:.FROD01 with CSMA-CD protocol
type 00-18, and host LOCAL:.FROD01 did not know what to do with it.
If the remote host is running OpenVMS, you can use SDA (ANALYZE/SYSTEM)
to examine the protocols active on the remote network controller, in an
effort to determine which remote application is associated with 00-18
on a remote network controller.
Of 'AA0004008C04AA0004008D040018'H, the key pieces here are the address
field 'AA0004008C04' and the protocol field '0018'. The protocol field
is obvious. To convert the address field (AA-00-04-00-8C-04) here, use
the last two bytes (8C04) -- reversed (048C) -- as the DECnet Phase IV
address. The value can then be converted to the DECnet Phase IV address
using the same scheme as described in the FAQ for converting the system
parameter SCSSYSTEMID.
