HP 501 Wireless Client Bridge V1.0.0.0 Configuration and Administration Guide

LLDP configuration 41
LLDP configuration
The HP 501 can use the Link-Layer Discovery Protocol (LLDP) to advertise information about
itself, such as the system name, port name, and system capabilities, to devices on the wired
network (LLDP information is not sent on the wireless network). This information can be useful
for network management and monitoring purposes.
The information contained in LLDP frames includes the device model and configured system
name, the base MAC address and IPv4 address, the Ethernet port speed and duplex, and the
maximum power needed by the device in milliwatts.
To configure LLDP settings, select Network > LLDP in the management tool. You can
configure the following settings:
LLDP mode
Enables or disables LLDP advertisements. By default, LLDP operation is enabled.
Transmit interval
The number of seconds between LLDP message transmissions. The default is 30 seconds.
Loop protection
The HP 501 supports loop protection, which prevents configuring both the wired and wireless
interfaces to use the same subnet.
When enabled, the software periodically sends loop protection packets to a reserved multicast
address on the wireless interface. If the multicast packet comes back to the HP 501 on the
Ethernet interface (with a source MAC addresses that identifies the wireless interface) within a
specified time, the software determines that a loop has occurred. The Ethernet interface is shut
down for a configured period, and a log entry is created.
To configure loop protection settings, select Network > Loop protection in the
management tool.
You can configure the following settings:
Loop protection mode
Enables and disables loop protection. It is enabled by default.
