Zorluk: OrtaLayer 2 Discovery Protocols (CDP and LLDP)

A network administrator is configuring and verifying Layer 2 discovery protocols across a enterprise topology consisting of Cisco and multi-vendor switches. Match each Cisco IOS command on the left with its corresponding operational scope and function on the right.

  • cdp runGlobal configuration command that enables Cisco Discovery Protocol across all supported device interfaces.
  • no cdp enableInterface configuration command that disables Cisco Discovery Protocol on a specific interface.
  • lldp transmitInterface configuration command that selectively enables sending Link Layer Discovery Protocol packets out of an interface.
  • show lldp neighbors detailPrivileged EXEC mode command that displays expanded neighbor information, including management IP addresses and system capabilities.

Cevap

The correct matches pair 'cdp run' with 'Global configuration command that enables Cisco Discovery Protocol across all supported device interfaces.', 'no cdp enable' with 'Interface configuration command that disables Cisco Discovery Protocol on a specific interface.', 'lldp transmit' with 'Interface configuration command that selectively enables sending Link Layer Discovery Protocol packets out of an interface.', and 'show lldp neighbors detail' with 'Privileged EXEC mode command that displays expanded neighbor information, including management IP addresses and system capabilities.'
Each Cisco IOS command corresponds directly to a specific scope and function: 'cdp run' turns on CDP globally across the chassis, 'no cdp enable' disables CDP on an individual port, 'lldp transmit' enables outbound LLDP packet transmission on a specific port, and 'show lldp neighbors detail' provides detailed neighbor operational information.

Adım Adım Çözüm

1
Identify the configuration scope (global vs. interface vs. EXEC mode) for each command.
'cdp run' is global configuration; 'no cdp enable' and 'lldp transmit' are interface configuration; 'show lldp neighbors detail' is EXEC mode verification.
Understanding mode syntax is critical for proper Layer 2 discovery protocol deployment.
2
Distinguish CDP single-state toggle from LLDP directional interface controls.
CDP uses 'cdp enable' / 'no cdp enable' per interface, whereas LLDP uses separate 'lldp transmit' and 'lldp receive' commands per interface.
LLDP provides granular directional transmission control that CDP does not.
3
Map each command to its precise definition.
Match left_1 to right_1, left_2 to right_2, left_3 to right_3, and left_4 to right_4.
Validates proper CLI syntax and operational scope for Cisco IOS discovery protocols.
