Link Layer Discovery Protocol

◆ Prevent Inter and Intra VAP client communication — When
enabled, clients cannot establish wireless communications with any
other client, either those associated to the same VAP interface or any
other VAP interface.
LINK LAYER DISCOVERY PROTOCOL
This page allows you to configure the Link Layer Discovery Protocol (LLDP).
LLDP allows devices in the local broadcast domain to share information
about themselves. LLDP-capable devices periodically transmit information
in messages called Type Length Value (TLV) fields to neighbor devices.
Advertised information is represented in Type Length Value (TLV) format
according to the IEEE 802.1ab standard, and can include details such as
device identification, capabilities and configuration settings.
This information can be used by SNMP applications to simplify
troubleshooting, enhance network management, and maintain an accurate
network topology.
Figure 35: LLDP Settings
The following items are displayed on this page:
◆ Disable/Enable — Disables/Enables LLDP on the access point.
◆ Message Transmission Hold Time — Configures the time-to-live
(TTL) value sent in LLDP advertisements as shown in the formula
below. (Range: 2-10; Default: 4)
The time-to-live tells the receiving LLDP agent how long to retain all
information pertaining to the sending LLDP agent if it does not transmit
updates in a timely manner. TTL in seconds is based on the following
rule: (Transmission Interval * Hold time) ≤ 65536. Therefore, the
default TTL is 4*30 = 120 seconds.
