Configure Service Location Protocol (SLP)

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. Access the Embedded Web Server and login as a System Administrator.

2. In the Embedded Web Server, click Properties→Connectivity→Setup.

3. In the Protocol area, for SLP, click Edit.

4. For Protocol, select Enabled.

5. For Directory Agent, type the IP address for the Directory Agent (DA), as needed.

6. To group services, for Scope 1, 2, and 3, type a name as needed. Printers cannot recognize services that are in different scopes.

7. For Message Type, select an option.

   • Multicast: This option routes multicast packets between subnets.

   • Broadcast: This option does not route packets between subnets.

8. Under Multicast Radius, type a value from 0 through 255. Multicast Radius defines how many routers the multicast packet can cross.

9. For Maximum Transmission Unit (MTU), type a value from 484 through 32768.
   
   Note: The maximum MTU for IP over Ethernet is 1500 bytes.
   
   

10. Click Save.

11. Log out as the administrator when finished.
