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 informa-
tional messages, which are normally printed to the standard output and log error mes-
sages 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 infor-
mation 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.
