Description: This exercise demonstrates the commands
required to configure parameters like guard-band and max power on a
PoE enabled interface.
Instructions:
1. Enter into PoE hierarchy mode on SW2 that has PoE enabled ports.
2. Guard-band syntax is “Set guard-band <watts>”. Range
to be set is 0 through 19 where default value is 0
3. Maximum power syntax is “Set interface (all | interface-name)
maximum-power <watts>”. Range to be set is 0.0 through 18.6
for EX3200 and EX4200 switches and 0.0 through 30.0 for EX2200
switches and Default is: 15.4 for EX3200 and EX4200 switches and 30.0
for EX2200 switches
4. Verify using show poe interface command that display status of
all PoE ports on the switch.

Note:
Guard-band: Reserve a specified amount
of power out of the PoE power budget in case of a spike in PoE
consumption.
Maximum-Power: Set the maximum amount of power that the switch
can supply to the PoE port.
