LLDP Ethernet Port Commands
lldp
Syntax lldp
Context config>port>ethernet
Description
This command enables the context to configure Link Layer Discovery Protocol (LLDP) parameters on the
specified port.
tunnel-nearest-bridge-dest-mac
Syntax [no] tunnel-nearest-bridge-dest-mac
Context config>port>ethernet>lldp
Description This command allows user to configure tunneling for LLDP frames that use the nearest-bridge-dest-mac as
destination MAC address. If enabled using the command tunnel-nearest-bridge-dest-mac, all frames
received with the appropriate destination mac address are forwarded transparently to the remote end of the
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 when using any other service.
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> dest-
mac 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:
Nearest-bridge mac
Admin status
Rx
Tx
Rx-Tx
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 where possible to conform to
standards. This command allows legacy LLDP implementations that do not support these additional
destinations MAC addresses to tunnel LLDP frames that use the nearest-bridge destination MAC address.
