Q. How do I get the Cisco Catalyst 2960-X Series out of switch hibernation mode?
A. The Cisco Catalyst 2960-X Series provides the following wake-up triggers from switch hibernation mode:
●
Wake on scheduled real-time clock alarm/trigger
●
Wake on mode button trigger
Q. Can Cisco Catalyst 2960-X Series Switches be scheduled to switch hibernation mode using the Cisco
EnergyWise management tool?
A. Yes, the switch hibernation mode is integrated with Cisco EnergyWise. Cisco Catalyst 2960-X Series
Switches can be put to switch hibernation mode using a Cisco EnergyWise management tool like any other IP
devices.
Q. Is it possible to wakeup a Cisco Catalyst 2960-X Series Switch in switch hibernation mode before the
scheduled wake-up time?
A. Yes, the mode button trigger will get the Cisco Catalyst 2960-X Series Switch out of switch hibernation mode.
Q. Can we schedule switch hibernation mode for some members only in a stack of Cisco Catalyst 2960-X Series
Switches?
A. No. The whole stack of Cisco Catalyst 2960-X Series Switches can only be scheduled to switch hibernation
mode.
Q. How long does it take for a Cisco Catalyst 2960-X Series Switch to be operational when it wakes up from
switch hibernation mode?
A. A Cisco Catalyst 2960-X Series Switch coming out of switch hibernation mode is similar to a switch booting
from reload. If the switches are stacked, master reelection is triggered after wake-up.
Q. Is Energy-Efficient Ethernet (EEE) 802.3az supported on the Cisco Catalyst 2960-X Series?
A. Yes, Energy-Efficient Ethernet (EEE) is supported on all downlink ports of the Cisco Catalyst 2960-X Series.
Q. Do we need to enable EEE on the Cisco Catalyst 2960-X Series?
A. EEE is enabled by default on all the downlink ports of the Cisco Catalyst 2960-X Series. If needed, EEE can
be disabled.
Q. How is power saved with EEE on the Cisco Catalyst 2960-X Series?
A. Cisco Catalyst 2960-X downlink ports switch to low-power idle (LPI) mode during gaps in the data stream,
saving power.
Q. Do both sides of the Ethernet interface have to support EEE for it to work?
A. Yes. Both endpoints of the Ethernet link must support EEE to get the power-saving advantages.
Q. How do I check if EEE is working?
A. The “show eee status interface Gigabit Ethernet xxx” command can be used to check if EEE is agreed
between both the endpoints.

Q. What management ports are available?
A. The Cisco Catalyst 2960-X Series provides two types of console ports and one out-of-band Ethernet port:
●
USB Type B console port
●
Standard RJ-45 serial port
