210 RUGGEDCOM Discovery Protocol (RCDP)
NOTE
LLDP is implemented to keep a record of only one device per Ethernet port. Therefore, if there are
multiple devices sending LLDP information to a switch port on which LLDP is enabled, information
about the neighbor on that port will change constantly.

RUGGEDCOM Discovery Protocol (RCDP)
RUGGEDCOM Discovery Protocol (RCDP) supports the deployment of RUGGEDCOM ROS-based devices that have
not been configured since leaving the factory. RUGGEDCOM ROS devices that have not been configured all have
the default IP (Layer 3) address. Connecting more than one of them on a Layer 2 network means that one cannot
use standard IP-based configuration tools to configure them. The behavior of IP-based mechanisms such as the
web interface, SSH, telnet, or SNMP will all be undefined.
Since RCDP operates at Layer 2, it can be used to reliably and unambiguously address multiple devices even
though they may share the same IP configuration.
Siemens's RUGGEDCOM Explorer is a lightweight, standalone Windows application that supports RCDP. It is
capable of discovering, identifying and performing basic configuration of RUGGEDCOM ROS-based devices via
RCDP. The features supported by RCDP include:
• Discovery of RUGGEDCOM ROS-based devices over a Layer 2 network.
• Retrieval of basic network configuration, RUGGEDCOM ROS version, order code, and serial number.
• Control of device LEDs for easy physical identification.
• Configuration of basic identification, networking, and authentication parameters.
For security reasons, RUGGEDCOM Explorer will attempt to disable RCDP on all devices when Explorer is shut
down. If RUGGEDCOM Explorer is unable to disable RCDP on a device, RUGGEDCOM ROS will automatically disable
RCDP after approximately one hour of inactivity.
NOTE
RCDP is not compatible with VLAN-based network configurations. For correct operation of RUGGEDCOM
Explorer, no VLANs (tagged or untagged) must be configured. All VLAN configuration items must be at
their default settings.
NOTE
RUGGEDCOM ROS responds to RCDP requests only. It does not under any circumstances initiate any
RCDP-based communication.
