VX640 Router Manual, Rev. D
36
August, 2013
The user must provide a table defining the partitions. This table is in the form of a comma separated
value (CSV) file located in /var/local/router/partition on the VX Router. This file contains the port
number and the partitions to which it belongs. The configuration file for the above scenario looks like this:
All ports not listed will default to partition 1. Ports can be manually added to partition 1.
Note: When using a Back-up Controller Card configuration, both controllers must have the
same Partition table.
The VX Router will interpret the Partition Table (csv file) during boot up. Any errors that occur during the
Partition Table interpretation process will be logged into the messages file at the following location:
var/log/messages
Note:
It is recommended that the messages File be reviewed and any errors in the Partition
Table be corrected before implementing partitions on the VX Router. It is also recommended that
the Partitioning function be fully tested before implementing on the VX Router.
The Partitioning Tables files for the Router are stored on the Controller Card at the following location:
var/local/router/partition/upstream.csv
var/local/router/partition/downstream.csv
(Note that the downstream.csv file is required for the VX160 and VX320.)
Partitioning function is disabled when Partitioning Table files are removed. By default, when there are no
partitioning files, all input and output ports will be partition 1. All VX Routers are shipped without
Partitioning Table files stored on the Controller card and therefore do not restrict any connection.
Note: When using a redundant Controller Card configuration, the Primary and Back-up
Controllers must have the same Partition Table files stored on each card.
To assure that both controllers are configured with the same files, run the following command(s) on the
Primary Controller:
F=/var/local/router/partition/upstream.csv ; ssh secondary cat $F | diff –bq $F - && echo ‘Files Match’
F=/var/local/router/partition/downstream.csv ; ssh secondary cat $F | diff –bq $F - && echo ‘Files Match’
(Note that the downstream.csv file is only required for the VX160 and VX320.)
If the files match, the command returns: Files Match
Note that the above commands should be re-run after any changes to the table files or when the SD card
has been changed.
