To configure LLDP

Before you begin

LLDP is a not a routing protocol, but instead, a neighbor-discovery protocol that allows an NE to advertise its identity and capabilities to other NEs attached to the same physical IEEE 802.1 LAN. As such, it is configured in a different manner than standard routing protocols.

Wavence supports Nearest Bridge LLDP. LLDP timers are not configurable.

LLDP is supported in the SM configuration only. An LLDP link with an SA or Connected node will appear as a link to an unmanaged NE. To avoid this, LLDP Administrative Status should be set to Disabled on SA and Connected NEs.

LLDP is supported on physical Ethernet ports and Ethernet LAG ports.

Note: The prerequisite for LLDP link to be discovered when ports are synchronous, is that the auto negotiation should be true on both end points of LLDP link and speed should be set to 1 Gb/s on both ports.

For more information about LLDP, see the NSP NFM-P Classic Management User Guide.

Steps
 
1 

Physically connect the NEs to each other using Ethernet cable.

2 

Perform the following on each NE:

  1. On the equipment tree, expand Network→Wavence→Card Slot.

  2. Right-click on the Ethernet port object and choose Properties. The Physical Port (Edit) form opens.

  3. Choose the LLDP tab, then the Nearest Bridge sub-tab, then the General sub-tab. Set the Administrative Status parameter to Tx and Rx to discover the remote peer and link.

    Note: If the Administrative Status is set to Disabled, LLDP will be disabled on the port.

  4. Choose the Ethernet tab, then the General sub-tab. Set the Auto-Negotiate parameter to True.

Results:

  • The NFM-P discovers the remote peer and adds it to the Remote Peers sub-tab in the LLDP tab.

  • The LLDP physical link is discovered and appears in green on the topology map.
