The information is in a Type Length Value (TLV) format for each data item. TLV information is
transmitted in a LLDP protocol data unit (LLDPDU), enclosed in an Ethernet frame and sent to a
destination MAC address. Certain TLVs are mandatory, and always sent once LLDP is enabled,
while other TLVs are optionally configured. LLDP defines a set of common advertisement
messages, a protocol for transmitting the advertisements and a method for storing information in
received advertisements. A switch can receive and record the TLVs, but not transmit them. The
information distributed using LLDP is stored by its recipients in a standard MIB, making it possible
for the information to be accessed by a NMS using a management protocol such as SNMP.
LLDP transmits periodic advertisements containing device information and media-specific
configuration information to neighbors attached to the same network. LLDP agents cannot solicit
information from other agents by using LLDP.
To configure LLDP support:
1. Select System Configuration - > LLDP from the menu tree.
2. Select the Enable LLDP radio button to enable or disable the transmission of LLDP
advertisements. LLDP is enabled by default.
3. Set a Refresh Interval (in seconds 5-32768) to define the LLDP
refresh-interval/transmit-interval. The Refresh Interval is the interval LLDP frames are
transmitted on behalf of the LLDP agent. The default is 30 seconds.
4. Set a Holdtime Multiplier (2-10) to define the holdtimemultiplier. This parameter is a multiplier
on the Refresh Interval that determines the actual TTL value used in an LLDPDU.The default
setting is 4.
5. Click Apply to save any changes to the LLDP screen. Navigating away from the screen without
clicking the Apply button results in all changes to the screen being lost.
6. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on LLDP screen to the last saved configuration.
Logging configuration
The Mobility 5181 Access Point provides the capability for periodically logging system events that
prove useful in assessing the throughput and performance of the Mobility 5181 Access Point or
troubleshooting problems on the Mobility 5181 Access Point managed Local Area Network (LAN).
Use the Logging Configuration screen to set the desired logging level (standard syslog levels) and
view or save the current Mobility 5181 Access Point system log.
