Partitioning
Partitions allow TLX, VX and MX fiber-optic Matrix Switch sources and destinations to be
segregated.
Therefore, destination work stations will only receive signals that are transmitted from
source computers in the same partition. In addition, it is impossible for a source computer to be
inadvertently routed outside of its designated partition as the signals will not be transmitted.
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
. This file contains the port number and the
partitions to which it belongs.
Example:
VX80 Switch with four distinct partitions:
Four partitions set up for secure routing and extension applications. Signals are only capable of
transmitting and receiving within a single partition and not across partitions
The maximum number of partitions is the number of ports that make up the Switch (12, 24, 80, 160, 320,
640). A VX80 Switch can be configured with up to 80 partitions, a VX160 up to 160, and so forth. There
are also overlapping partition configurations.
EXAMPLE: A VX80 with four partitions
The following example shows a VX80 Switch with an overlapping partition
(Ports 5-10 are accessible to
both partitions 2 and 3):
The Partition Table files for the TLX160 are stored in the on-board Controller at:
var/local/router/partition/upstream.csv
At system power up, upon becoming active after the initial boot-up, the
Primary Control Card
will only
evaluate its Partition Table (upstream.csv file) once. The
Secondary Control Card
will NOT evaluate its
Partition Table (upstream.csv file) at initial boot-up, but rather when a switchover occurs from Primary to
