NAME

isisd — the Intermediate System to Intermediate System (IS-IS) routing daemon

SYNOPSIS

/usr/sbin/isisd [-C | -c] [-f config_file] [-N] [-n] [-q] [-t trace_options] [trace_file]

DESCRIPTION

isisd is a routing component that works with Route Administration Manager (RAMD) for IPv6. This routing daemon is an implementation of Intermediate System to Intermediate System (IS-IS) Protocol for IPv6. IS-IS conforms to ISO standard 10589, RFC 1195, and draft-ietf-isis-ipv6-03.txt.

isisd is invoked automatically if it is enabled in the /etc/ramd.conf configuration file.

Options

isisd supports the following command-line options:

-C | -c

Parses the configuration file for syntax errors and terminates isisd. isisd exits with a status 0 if the configuration file contains no error. In case of any error, isisd exits with a non-zero value. isisd prints the configuration file errors, if any, to the standard output.

-C and -c performs the same function.

-f config_file

Specifies an alternate configuration file to be used by isisd. By default, isisd uses the /etc/ramd.conf configuration file.

-N

Specifies that isisd runs as a normal process and not as a daemon process.

-n

Specifies that isisd does not modify the kernel forwarding table. That is, isisd will not send route updates to ramd.

-q

Suppresses stderr messages of isisd. Using this option, you can suppress informational messages, which are normally printed to the standard output and log error messages via syslogd(1M). By default, syslog errors are logged to /var/adm/syslog/syslog.log.

-t trace_options

Specifies a comma-separated list of trace options to be enabled at the time of startup. No space is allowed between this option and its arguments. See ramd.conf(4) for information on valid trace options and tracing.

trace_file

Name of the file used by daemon to log tracing information. If trace options are specified without specifying a trace file, isisd uses the default trace file /var/tmp/isisd/isisd.log.

Signal Processing

The following signals may be used to control isisd:

SIGHUP

A SIGHUP causes isisd to reread the configuration file. isisd reads the configuration file and reconfigures its policies.

SIGINT

The current state of isisd is written to /var/tmp/isisd/isisd.dump.

SIGTERM

Graceful shutdown. On receipt of SIGTERM, isisd attempts a graceful shutdown. All isisd routes are removed from the kernel's routing table on receipt of SIGTERM.

SIGUSR1

Toggle tracing. If the tracing is currently enabled, this signal suspends tracing and closes trace file. If tracing is currently disabled, the trace file will be reopened and tracing initiated. This is useful for moving trace files.

It is not possible to use SIGUSR1 if tracing is not enabled in the configuration file.
