information. The receiving LLDP agent discards all information related to the sending LLDP
agent after the time interval indicated in the TTL field is complete.
Note: A TTL value of zero can be used to signal that the sending LLDP port has initiated a port
shutdown procedure.
The End Of LLDPDU TLV indicates the end of the LLDPDU.

LLDP Tunneling for Epipe Service

Customers who subscribe to Epipe service consider the Epipe as a wire, and run LLDP between
their devices which are located at each end of the Epipe. To facilitate this, the 7210 devices
support tunneling of LLDP frames that use the nearest bridge destination MAC address.
If enabled using the command tunnel-nearest-bridge-dest-mac, all frames received with the
matching LLDP destination mac address are forwarded transparently to the remote end of the
Epipe service. To forward these frames transparently, the port on which tunneling is enabled must
be configured with NULL SAP and the NULL SAP must be configured in an Epipe service.
Tunneling is not supported for any other port encapsulation or other services.
Additionally, before enabling tunneling, admin status for LLDP dest-mac nearest-bridge must be
set to disabled or Tx only, using the command admin-status available under configure> port>
ethernet> lldp> destmac-nearest-bridge. If admin-status for dest-mac nearest-bridge is set to
receive and process nearest-bridge LLDPDUs (that is, if either rx or tx-rx is set) then it overrides
the tunnel-nearest-bridge-dest-mac command.
The following table lists the behavior for LLDP with different values set in use for admin-status
and when tunneling is enabled or disabled:

NOTE: Transparent forwarding of LLDP frames can be achieved using the standard defined
mechanism when using the either nearest-non-tmpr or the nearest-customer as the destination
MAC address in the LLDP frames. It is recommended that the customers use these MAC address
