HPE6-A73 Exam - Question 29

Question

A company has recently upgraded their campus switching infrastructure with AOS-CX switches. They have implemented 802.1X authentication on access ports where laptop and IOT devices typically connect. An administrator has noticed that for POE devices, the AOS-CX switch ports are delivering the maximum wattage to the port instead of what the device actually needs. Upon connecting the IoT devices, the devices request the maximum wattage through information exchange.

Concerned about this waste of electricity, what should the administrator implement to solve this problem?

Examice · Accepted Answer

To address the problem of delivering excess power to PoE devices, the administrator should create device profiles with the correct power definitions. By specifying the appropriate power requirements for each device type, the switch will allocate the power efficiently based on the actual needs of the connected devices rather than providing the maximum wattage. This will help prevent unnecessary power wastage.

Agree C:
When phones receive Power over Ethernet (PoE) from the switch, LLDP- MED can help the switch allocate and deliver exactly the power that the phone needs.
If you are implementing authentication on the port, like 802.1X, MAC authentication, or captive portal, remember to allow LLDP:
switch(config)# interface <interface- ID> switch(config- if)# aaa authentication port- access allow- lldp- bpdu

Answer C
- Disable LLDP on the switch makes no sense.

Answer C
- The negotiation must take place before the authentication. Whether for LLDP or CDP (e.g.: voip phone or camera)

How can C Be correct if it says EXEMPT LLDP / CDP from the interface?
