Match each Layer 2 discovery protocol attribute or configuration parameter on the left to its corresponding protocol or timer specification on the right.
- Cisco proprietary protocol enabled globally by default on Cisco switch platformsCisco Discovery Protocol (CDP)
- Vendor-neutral discovery protocol standardized under IEEE 802.1ABLink Layer Discovery Protocol (LLDP)
- Protocol default update frequency of 60 seconds with a holdtime of 180 secondsCDP Default Timers
- Protocol default update frequency of 30 seconds with a holdtime of 120 secondsLLDP Default Timers
Cevap
The Cisco proprietary protocol matches Cisco Discovery Protocol (CDP). The IEEE 802.1AB standard matches Link Layer Discovery Protocol (LLDP). The 60-second update and 180-second holdtime match CDP Default Timers. The 30-second update and 120-second holdtime match LLDP Default Timers.
Each left-side item correctly correlates to its designated discovery protocol origin, governing IEEE specification, or default timer values.
