# SSDP
Device Management > Configuration > Network > SSDP

Configure settings for Simple Service Discovery Protocol (SSDP).
SSDP enables the device to inform users of its functions and searches for other devices on a UPnP network and others.

Note

- Settings on this page can be changed by the following administrator:
  - Network Administrator

### SSDP

Specify whether SSDP is active or inactive. The default is Active.

### UUID

Displays a UUID (Universally Unique Identifier) for the SSDP. This value is automatically set and cannot be changed. UUID is a universally unique identifier used to identify a device.

Note

- UUID is also used to identify a device with WSD (Web Services on Devices).

### Profile Expires

Enter a profile expiration time in seconds. This specifies the interval at which profile information detected by SSDP is updated. Enter from 1801 to 86400. The default is 10800. The profile includes information such as device location and functions, which is required when searching for devices using SSDP.

### TTL

Enter the number of routers a packet can pass through to transfer SSDP service status. Enter from 1 to 255. The default is 4. TTL (Time To Live) is the life span of a packet on the network. Every time a packet passes through a router, the value entered here decreases. When the value reaches 0, the data transfer is canceled.

Note

- If a router that is incompatible with multicast is connected to the device, SSDP service status can be transferred only within the subnet to which the device is connected.
