8.5.7 Route Filters
The Route Filters setting restricts routing or processing of some PakBus message
types so that a "state changing" message can only be processed or forwarded by
this CR1000 if the source address of that message is in one of the source ranges
and the destination address of that message is in the corresponding destination
range. If no ranges are specified (the default), the CR1000 will not apply any
routing restrictions. "State changing" message types include set variable, table
reset, file control send file, set settings, and revert settings.
For example, if this setting was set to a value of (4094, 4094, 1, 10), the CR1000
would only process or forward "state changing" messages that originated from
address 4094 and were destined to an address in the range between one and ten.
This is displayed and parsed using the following formal syntax:
route-filters := { "(" source-begin "," source-end ","
dest-begin "," dest-end ")" }.
source-begin := uint2. ; 1 < source-begin <= 4094
source-end := uint2. ; source-begin <= source-end <= 4094
dest-begin := uint2. ; 1 < dest-begin <= 4094
dest-end := uint2. ; dest-begin <= dest-end <= 4094
8.5.8 PakBusRoutes
PakBusRoutes() lists the routes (in the case of a router), or the router neighbors
(in the case of a leaf node), that were known to the CR1000 at the time the setting
was read. Each route is represented by four components separated by commas
and enclosed in parentheses:
PakBusRoutes(port, via neighbor adr, pakbus adr, response time)
Descriptions of PakBusRoutes() parameters:
port
Specifies a numeric code for the port the router will use:
