Using the Call In-Progress Feature
Use this feature, also referred to as activity check, to configure the switch to wait until a Cisco IP phone
connected to a PoE port is not sending or receiving traffic before powering off the port.
Use the energywise activitycheck interface configuration command on these Cisco devices:
• Catalyst 6500 switches (see the Cisco IOS Release Notes for Cisco EnergyWise, EnergyWise
Phase
2 for the specific devices)
• Catalyst 4500 switches
Note Before powering off a PoE port, Catalyst 6500 and Catalyst 4500 switches use interface statistics
to determine when a Cisco IP phone connected to the PoE port is not sending or receiving traffic.
• Catalyst 3750-X, 3750-E, 3750, 3560-X, 3650-E, 3560, and 2960 switches
• Cisco EtherSwitch service modules (NME-16ES-1G, NME-16ES-1G-P, NME-X-23ES-1G,
NME-X-23ES-1G-P, NME-XD-24ES-1S-P, NME-XD-48ES-2S-P)
• Cisco enhanced EtherSwitch service modules (SM-D-ES2-48, SM-D-ES3-48-P, SM-D-ES3G-48-P,
SM-ES2-16-P, SM-ES2-24, SM-ES2-24-P, SM-ES3-16-P, SM-ES3-24-P, SM-ES3G-16-P,
SM-ES3G-24-P)
Before entering the energywise activitycheck command on devices other than Catalyst 6500 and 4500
switches, you must enable automatic quality of service (auto-QoS) for VoIP on the port with this
configuration:
• All packets from the IP phone have the class of service (CoS) value 5.
To verify this, use the show mls qos maps cos-output-q privileged EXEC command to display the
CoS output queue threshold map.
This example shows that CoS value 5 is mapped to queue 1 and threshold 3 on the Gigabit
Ethernet
0/1:
Cos-outputq-threshold map:
cos: 0 1 2 3 4 5 6 7
------------------------------------
queue-threshold: 4-3 4-2 3-3 2-3 3-3 1-3 2-3 2-3
This is the configuration for the PoE port:

• Auto-QoS for VoIP is enabled on the PoE port.
• Auto-QoS is enabled on the IP phone. The switch does not change the CoS value in the packet from
the IP phone.
