Configuring SLP Properties
SLP configuration properties control network interactions, SLP agent characteristics, status, and logging. In
most situations, the default configuration of these properties requires no modification. However, you
can use the procedures in this chapter when the network medium or topology
changes and to achieve the following goals:
Compensate for network latencies
Reduce congestion on the network
Add agents or reassign IP addresses
Activate SLP logging
You can edit the SLP configuration file, /etc/inet/slp.conf, to perform operations
such as those shown in the following table.
Table 9-1 SLP Configuration Operations
Specify whether slpd should act
as a DA server. SA server is the default.
Set the net.slpisDA property to
Set timing for DA multicast messages.
Set the net.slp.DAHeartBeat property to control how often
a DA multicasts an unsolicited DA advertisement.
Enable DA logging to monitor network
Set the net.slp.traceDATraffic property to True.
SLP Configuration File: Basic Elements
The /etc/inet/slp.conf file defines and activates all SLP activity each time you restart
the SLP daemon. The configuration file consists of the following elements:
All of the basic SLP properties, such as net.slp.isDA and net.slp.DAHeartBeat, are
named in the following format.
SLP behavior is defined by the value of a property or a
combination of properties in the slp.conf file. Properties are structured as key-value pairs in
the SLP configuration file. As shown in the following example, a key-value pair
consists of a property name and an associated setting.
The key for each property is the property name. The value sets
the numeric (distance or time), true/false state, or string value parameters for the
property. Property values consist of one of the following data types:
If the value defined is not allowed, the default value for that
property name is used. In addition, an error message is logged using syslog.
Comment Lines and Notations
You can add comments to the slp.conf file that describe the nature and
function of the line. Comment lines are optional in the file, but can
be useful for administration.
Note - Settings in the configuration file are case insensitive. For more information, refer to:
Guttman, Erik, James Kempf, and Charles Perkins, “Service Templates and service: scheme,” RFC
2609 from the Internet Engineering Task Force (IETF). [https://www.ietf.org/rfc/rfc2609.txt]
How to Change Your SLP Configuration
Use this procedure to change the property settings in your SLP configuration file.
SLP– enabled client or service software also can alter the SLP configuration by
using the SLP API. This API is documented in “An API for Service
Location,” RFC 2614 from the Internet Engineering Task Force (IETF). [https://www.ietf.org/rfc/rfc2614.txt]
- Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
To configure a role with the Primary Administrator profile, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
- Stop slpd and all SLP activity on the host.
# svcadm disable network/slp
- Back up the default /etc/inet/slp.conf file before you change the configuration settings.
- Edit the property settings in the /etc/inet/slp.conf file as necessary.
Refer to Configuration Properties for general information about the SLP property settings. See the
sections that follow this procedure for examples of different scenarios in which you
might change the slp.conf properties. See slp.conf(4).
- Save your changes and close the file.
- Restart slpd to activate your changes.
# svcadm enable network/slp
Note - The SLP daemon obtains information from the configuration file when you stop or
Example 9-1 Setting up slpd
to Operate as a DA Server
You can change the SA server default to enable slpd to operate as
a DA server by setting the net.slp.isDA property to True in the slpd.conf
In each area, various properties control different aspects of the configuration. The following
sections describe different scenarios in which you might change the default property settings
that are used in SLP configuration.
