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.
