SLP 
Printers use Service Location Protocol (SLP) to announce and look up services on a local network without 
prior configuration. When SLP is enabled, the printer becomes a Service Agent (SA) and announces its 
services to User Agents (UA) on the network using SLP. 
Directory Agents (DA) are components that cache services. They are used in larger networks to reduce 
the amount of traffic. DAs are optional. If a DA is present, then User Agents (UAs) and System Agents 
(SAs) are required to use it instead of communicating directly with the printer. 
 
Configuring SLP 
1.  In CentreWare Internet Services, click Properties>Connectivity>Setup. 
2.  Under Protocol, next to SLP, click Edit. 
3.  Under Protocol, select Enabled. 
4.  Under Directory Agent, type the IP address for the Directory Agent (DA) as needed. 
5.  To group services, under Scope 1, 2, and 3, type a name as needed. Printers cannot recognize 
services that are in different scopes. 
6.  Under Message Type, select an option: 
−  Multicast routes multicast packets between subnets. 
−  Broadcast does not route packets between subnets. 
7.  Under Multicast Radius, type a value from 0 through 255. 
Multicast Radius defines how many routers the multicast packet can cross. 
8.  Under Maximum Transmission Unit (MTU), type a value from 484 through 32768. 
 
Note: The maximum MTU for IP over Ethernet is 1500 bytes. 
 
9.  Click Save.
