NAME

hyroute − set the hyperchannel routine tables

SYNOPSIS

hyroute [ −s ] [ −p ] [ −c ] [ −l ] [ −d ] [ file ]

DESCRIPTION

Hyroute manipulates the Hyperchannel routing information. 

With the −s option, it reads file and sets the system’s database according to the information in the file (see below).  If no input file is given, or if the argument ‘−’ is encountered, hyroute reads from standard input. 

The −c option causes hyroute to compare the system’s current information to that contained in file.

The −p option causes a digested version of file to be printed. 

The −d option causes a "dump" of the system’s table (used for debugging routing code). 

FILE FORMAT

The input file is free format.  Comment lines start with a ’*’ in column one.  Statements end with a semicolon. 

direct host dest control access ;

Describes a host that can be directly reached from this adapter.  Host is a host name as listed /usr/lib/hosts, dest, control, and access are hexadecimal numbers.  The data will be send to hyperchannel address dest using a control value of control and an access code of access (see adapter manuals for details). 

The specified remote adapter and the local adapter must both be connected to one or more common trunks or connected to trunks that are connected with with link adapters. 

gateway host gate1 gate2 gate3 ... ;

Describes a host that must be reached indirectly through any one of the hosts indicated by gaten. The hosts listed are not gateways in the formal sense (they don’t run the internet gateway protocols), but are hosts on the hyperchannel can "bridge" between subsections of the hyperchannel network.
