Neighbor Discovery; Configuring Lldp; Enabling Lldp Globally - Cisco NCS1004 Manual

Configuring Controllers
The LLDP is also a device discovery protocol that runs over Layer 2. This protocol allows the network
management applications to automatically discover and learn about other non-Cisco devices that connect to
the network.
Interoperability between non-Cisco devices using LLDP
LLDP is also a neighbor discovery protocol that is used by network devices to advertise information about
themselves to other devices on the network. This protocol runs over the data link layer, which allows two
systems running different network layer protocols to learn about each other.
With LLDP, the user can also access the information about a particular physical network connection. If the
user uses a non-Cisco monitoring tool (through SNMP), LLDP helps you identify the Object Identifiers (OIDs)
that the system supports. The following OIDs are supported:
• 1.0.8802.1.1.2.1.4.1.1.4
• 1.0.8802.1.1.2.1.4.1.1.5
• 1.0.8802.1.1.2.1.4.1.1.6
• 1.0.8802.1.1.2.1.4.1.1.7
• 1.0.8802.1.1.2.1.4.1.1.8
• 1.0.8802.1.1.2.1.4.1.1.9
• 1.0.8802.1.1.2.1.4.1.1.10
• 1.0.8802.1.1.2.1.4.1.1.11
• 1.0.8802.1.1.2.1.4.1.1.12

Neighbor Discovery

System advertises the LLDP TLV (Type Length Value) details over the management network using which
other devices in the management network can learn about this device.

Configuring LLDP

• LLDP full stack functionality is supported on all three management interfaces supported in NCS 1004.
• You can selectively enable or disable LLDP on any of the management interfaces on demand.
• You can selectively enable or disable LLDP transmit or receive functionality at the management interface
level.
• Information gathered using LLDP can be stored in the device Management Information Database (MIB)
and queried with the Simple Network Management protocol (SNMP).
• LLDP operational data are available in both Command Line Interface and netconf-yang interface.

Enabling LLDP Globally

When you enable LLDP globally, all interfaces that support LLDP are automatically enabled for both transmit
and receive operations.
Note
You can override this default operation at the interface to disable receive or transmit operations.
