zreg - Read and write registers and tables on the OpenArchitect switch switching hardware.

zreg [-p <ppa>] [-w] [-i <index>] [-t <index>] [-k] [-h 

<hostname>] [-d <level>] [-r 10] <reg>

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.

-p <ppa>

Specify the Physical Point of Attachment (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

Causes zreg to write to the register or table. Data to be 

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

Causes zreg to access the memory specified by <reg>. The 

entry accessed is determined using the data from standard 
input as the search key.  Enter 0 for fields that are not part 

of the search key. 

-h <hostname>

Specify the <hostname> to configure. By
