Filter Description (Syntax)
Format:
fin <default> {<rule>}*
<default> ::= {+ | -}[{l | h}]
<rule> ::= {+ | -}[{l | h}][r][d]{0-9}* [<idl> [<idh>]]
Definition of filter rules:
+
the message is accepted
-
the message is discarded
h
the message is assigned a high priority, as long as it is
supported by the interface
(LED interface: errors are signaled by CAN LEDs)
l
the message is given a low priority
(LED Interface: errors are signaled by Ethernet LEDs)
Determining the area of application for a filter rule:
<idl>
first CAN identifier (as hexadecimal number) for which
the filter rule applies. If no CAN identifier is given, the
filter rule can apply for any CAN identifier.
<idh>
last CAN identifier (as hexadecimal number) for which
this filter rule applies. If only one CAN identifier is
given, then the filter rule only applies for this CAN
identifier.
r
this rule applies for CAN RTR
4
frames
d
this rule applies for CAN data frames
0-9
this rule applies for messages that come from the
interface with the interface ID "x"
(to determine the
interface ID with the command
ls,
refer to section
4.5.2)
. If no number is given then all interfaces are
accepted.
If individual CAN identifiers are filtered then
<idh>
is not required.
