Configure SLP
Configure Service Location Protocol (SLP) if needed to support CUPS, Mac OS, and NetWare.
SLP is used to announce and look up services on a local network. When SLP is enabled, the device
becomes a Service Agent (SA) and announces its services on the network to User Agents (UA), who
search for services, using SLP.
Note: To configure this feature or these settings access the Properties tab as a System
Administrator. For details, refer to Access Internet Services as System Administrator on page 24.
1. From the Properties tab, click on the [Connectivity] link.
2. Click on the [Protocols] link.
3. Select [SLP] in the directory tree.
4. In the General area:
a. For Protocol, check the [Enabled] checkbox to enable Service Location Protocol (SLP).
b. Enter an IP Address for the [Directory Agent], if required. This will specify the address of a
single Directory Agent (DA) to be added to the list of Directory Agents in the device’s DA list.
c. Enter the required name(s) for [Scope 1,2,3], this allows the System Administrator to set one
of the three manually configurable scope names. A scope is a searchable group or container
to which an agent may be associated. The default scope is called “DEFAULT”.
d. For Message Type, select either [Multicast] or [Broadcast] from the drop-down menu. This
setting defines whether SLP will use multicast or broadcast in communications. Multicast
packets are routed between subnets as needed, but broadcast are not.
e. Enter a value for Multicast Radius (0-255), the default is 255. This allows the System
Administrator to reconfigure the Multicast Radius for SLP. This is similar to the Time To Live
(TTL) in the TCP/IP parameter, and defines how many routers the multicast packet may cross.
f. Enter a value for MTU to set the Maximum Transmission Unit (484 - 32768), with 1400 as
the default. This allows the System Administrator to set the maximum packet size for SLP.
g. Version will display the SLP version number supported by the device.
h. Port Number will display the socket (port) that all SLP communications will use. All devices
are required to listen on port 427 for UDP and TCP packets.
i. Character Set will display the character set in use. The default is US-ASCII.
5. Click on the [Apply] button to accept the changes or [Undo] to return the settings to their
previous values.
6. Click on the [OK] button when you see the message “Properties have been successfully
modified”.
