N o t e
Enter no lldp send without any options to prevent the interface from trans-
mitting any messages.
You can restrict the interface from sending only certain messages by entering
the no form of the lldp send command followed by the specific option. For
example, if a WAN interface transmits the management address into an
untrusted environment, hackers could attempt to access your router. On the
other hand, sending this address to authorized management processes allows
network administrators at hub sites to access and manage routers at
remote sites.
Preventing interfaces from sending messages that you consider less important
can minimize the protocol's chattiness.
Refer to Table 12-1 for the commands for suppressing or enabling specific
types of LLDP messages.
Table 12-1. Suppressing and Enabling LLDP Messages
Message
IP address for the interface's
management agent
interface's port ID
system capabilities (for example, router
or bridge)
router model and software version
router's hostname
LLDP messages must include a MAC address (chassis ID). If you do not want
the interface to send its MAC address, you must prevent it from transmitting
any LLDP messages.
Even after you prevent an interface from transmitting LLDP messages, it can
still listen for them.
