JNCIP-ENT IP Telephony Features Practice Question
You are configuring Power over Ethernet (PoE) on an EX4300 switch to power an IP phone requiring 15.4W (802.3af). By default, the switch allocates power based on dynamic classification. However, the IP phone frequently reboots under heavy traffic load. Which command should you configure on the switch interface to ensure the phone receives a guaranteed dedicated power budget?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set poe interface ge-0/0/14 consumption 15400
Configuring the power consumption limit manually via CLI ensures the switch reserves the exact required wattage rather than relying on dynamic classification which can sometimes underestimate bursts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set protocols lldp-med interface ge-0/0/14 power-over-ethernet budget 15400
Why it's wrong here
LLDP-MED negotiates power dynamically, but the static override command belongs to the system poe hierarchy.
- ✗
set interfaces ge-0/0/14 poe priority high
Why it's wrong here
Priority only determines which ports shed power first during a budget deficit, not the allocated power budget of a specific port.
- ✓
set poe interface ge-0/0/14 consumption 15400
Why this is correct
The consumption command manually overrides dynamic classification by setting a specific power limit in milliwatts.
- ✗
set poe interface ge-0/0/14 max-power 15.4w
Why it's wrong here
The max-power parameter syntax is incorrect for Junos PoE configuration.
