2. Alter the intervals in the LLDP Setup window to the desired time in hours,
minutes, and seconds:
a. The transmit interval determines how often an interface sends out
LLDP messages during normal operations. Enter a time in the Trans-
mit Interval hours, min., and sec. fields.
b. Interface can send messages more often than the transmit interval.
For example, a flapping interface can send messages out again and
again as it goes up and down. If LLDP messages are causing too much
overhead, you can force the interface to wait a set amount of time
before transmitting a new message by raising the minimum transmit
interval. Enter a time in the Minimum Transmit Interval hours,
min., and sec. fields.
c. The interface sets the TTL field for LLDP messages by multiplying the
transmit interval by the TTL multiplier. By default, this multiplier is
four. You can alter the TTL indirectly by changing the value in the TTL
Multiplier field.
3. Click Apply.
4. Clicking the Reset button returns settings to those established the last time
you clicked Apply. The Reset button does not return settings to the factory
defaults.

Enabling and Disabling LLDP on an Interface

By default, all Ethernet and WAN interfaces send and receive all types of LLDP
messages. These messages include the interface's:
MAC address
port ID
router model and Secure Router OS software version
router's hostname
system capabilities
management agent's network address
You should be careful of the information WAN interfaces transmit, particularly
on routers that connect to an external network. An unauthorized device can
learn a great deal about your system from LLDP messages.
You can prevent individual interfaces from both sending and listening for
LLDP messages. You can also limit the interface to either transmitting or
receiving messages.
