zreg
NAME
zreg - Read and write registers and tables on the OpenArchitect switch switching hardware.
SYNOPSIS
zreg [-p <ppa>] [-w] [-i <index>] [-t <index>] [-k] [-h
<hostname>] [-d <level>] [-r 10] <reg>
DESCRIPTION
zreg allows a user to read and write direct and indirect registers and tables on the resident
switch chip. zreg is commonly used for debug, or for prototyping when creating applications
that control the OpenArchitect switch. It is also useful when put into shell scripts for displaying
hardware status or statistics. Although the -t option allows tables to be displayed, one might find
the formatted output of the table functions more useful. See zal.
OPTIONS
-p <ppa>
Each OpenArchitect switch that is controlled by the CPU on
which zreg is running is a unique PPA. If there is only one
OpenArchitect switch, as would be the case when zreg is
running on the embedded processor the PPA would be 0. The
default PPA is 0.
-w
written is read from standard input.
-i <index> Causes zreg to access at the indexed register
specified by <reg>. See OPERANDS for usage of <reg> with
indexed registers. The <index> parameter is used to determine
which entry i
-t <index> Causes zreg to access the memory specified by
<reg>. The <index> parameter is used as the index into the
specified table. Only content addressable memories are
accessed using the –t option. All other tables and memories
are accessed with the –i option.
-k
entry accessed is determined using the data from standard
input as the search key.
