Managing LLDP

The IEEE 802.1AB defined standard, Link Layer Discovery Protocol (LLDP), allows stations residing on an 802
LAN to advertise major capabilities and physical descriptions. This information is viewed by a network manager
to identify system topology and detect bad configurations on the LAN.
LLDP is a one-way protocol; there are no request/response sequences. Information is advertised by stations
implementing the transmit function, and is received and processed by stations implementing the receive
function. The transmit and receive functions can be enabled/disabled separately per port. By default, both
transmit and receive are disabled on all ports. The application is responsible for starting each transmit and
receive state machine appropriately, based on the configured status and operational state of the port.
D-Link DWS-4000 Series allows LLDP to have multiple LLDP neighbors per interface. The number of such
neighbors is limited by the memory constraints. A product-specific constant defines the maximum number of
neighbors supported by the switch. There is no restriction on the number of neighbors supported on a per
LLDP port. If all the remote entries on the switch are filled up, then the new neighbors are ignored. In case of
multiple VOIP devices on a single interface, the 802.1ab component sends the Voice VLAN configuration to all
the VoIP devices.

Table 140: DHCP Snooping Interface Configuration
Description
Specifies the rate limit value for DHCP snooping purposes. If the incoming rate
of DHCP packets exceeds the value of this object for consecutively burst
interval seconds, the port will be shutdown. If this value is None, there is no
limit. The default is 15 packets per second (pps). The Rate Limit range is 0 to
300.
Specifies the burst interval value for rate limiting purposes on this interface. If
the rate limit is None, the burst interval has no meaning and displays it as "N/
A". The default is 1 second. The Burst Interval range is 1 to 15.
