Device Discovery Configuration

C.

If a third-party device does not support Cisco Discovery Protocol (CDP), the network administrator can use Link Layer Discovery Protocol (LLDP) to allow the device to be discovered on the network.

LLDP is a vendor-neutral protocol that allows network devices to advertise information about themselves to their directly connected neighbors. LLDP works by sending LLDP frames, which contain information such as the device's name, management IP address, and supported capabilities.

To enable LLDP on a Cisco switch, use the following commands:

cCopy code
switch# configure terminal switch(config)# lldp run 

This will enable LLDP on the switch, and the switch will begin sending LLDP frames to its directly connected neighbors. If the third-party device also supports LLDP, it will send its own LLDP frames back to the switch, and the switch will be able to discover the device.

If the third-party device does not support LLDP, other protocols such as SNMP (Simple Network Management Protocol) or TFTP (Trivial File Transfer Protocol) can be used to discover the device.

SNMP is a protocol used for managing and monitoring network devices. It allows network administrators to query devices for information such as their configuration, performance, and status. SNMP can be used to discover devices on the network by querying them for information about their network interfaces or other characteristics.

TFTP is a simple file transfer protocol that can be used to transfer files between network devices. It can also be used to discover devices on the network by transferring a configuration file to the device and examining the device's response.

LACP (Link Aggregation Control Protocol) is not used for device discovery, but rather for link aggregation, which allows multiple physical links to be combined into a single logical link for increased bandwidth and redundancy.
