Q.    What is the difference between the Cisco IOS Software feature sets?
A.     The differences between the three Cisco IOS Software feature sets are:

   LAN Lite feature set has entry-level Layer 2 features and is targeted at midmarket deployments.

   LAN Base feature set comes with advanced Layer 2 features and is typically targeted at enterprise customers.

   IP Lite feature set comes with enterprise access Layer 3 features and is typically targeted at enterprise customers.

Q.    How can I tell the difference between IP Lite, LAN Base, and LAN Lite switches for the Cisco Catalyst 2960-X Series?
A.     Cisco Catalyst 2960-X Series front panel sticker has the feature set name. From the rear of the Cisco Catalyst 2960-X Series Switch, the LAN Lite models do not support stacking. The left side will not have a location for the FlexStack-Plus module to be inserted.
From the Cisco IOS Software command line, there are two ways to tell which software image the switch has.

   The last letter in the product ID. If the last letter is “-L,” it’s LAN Base. If it’s “-LL,” it’s LAN Lite. If it’s “-I,” it’s IP Lite.

For example:

WS-C2960XR-48FPS-I is IP Lite.

WS-C2960X-48LPS-L is LAN Base.

WS-C2960X-48TS-LL is LAN Lite.

   The output from the “show license” Cisco IOS Software command-line interface (CLI) command. If LAN Base is being used, that will be the active license. If it’s LAN Lite, that will be the active license. In the following example output, LAN Base is the active license.

Q.    What are the stackable models of the Cisco Catalyst 2960-X Series?
A.     The LAN Base and IP Lite feature set models are stackable models in the Cisco Catalyst 2960-X Series. The LAN Lite feature set model is a standalone model. Note: The fanless SKU (WS-C2960S-PSQ-L with Lan Base) does not support stacking
Q.    Can LAN Base and IP Lite feature set models stack together in the Cisco Catalyst 2960-X Series?
A.     No, LAN Base and IP Lite feature set models cannot be stacked together. LAN Base feature set models can stack with LAN Base feature set models only. Similarly, IP Lite feature set models can stack with IP Lite feature set models only.
Q.    Can Cisco Catalyst 2960-X switches stack with Cisco Catalyst 2960-XR switches?
A.     No. Cisco Catalyst 2960-X and 2960-XR switches can’t stack together since they don’t share common feature set model.
Q.    What are the FlexStack-Plus high-availability features?
A.     The following features enhance high availability and manageability across a stack:

   Cross-stack EtherChannel

   SPAN

   FlexLink technology

   Hitless voice calls

Investment Protection

Q.    Is FlexStack-Plus stacking backward compatible with FlexStack?
A.     Yes. Unlike competing products, the FlexStack-Plus stacking is backward compatible with FlexStack to preserve customer investment. This allows mixed stacking of Cisco Catalyst 2960-S and Cisco Catalyst 2960-SF LAN Base series with 2960-X LAN Base series for investment protection.
Q.    What is a mixed stack?
A.     The stack is called a mixed stack if it has both the Cisco Catalyst 2960-S Series Switch and Cisco Catalyst 2960-X Series Switches. The mixed stack features are limited to Cisco Catalyst 2960-S Series features. (See Table 4.)

Q.    Does mix stack require any configuration on Cisco Catalyst 2960-X switches?
A.     Yes. The switch stack speed should be changed using configure mode command “switch stack port-speed 10” on Cisco Catalyst 2960-X switches to stack with Cisco Catalyst 2960-S switches. While forming a homogenous stack of Cisco Catalyst 2960-X revert back the stack speed using “no switch stack port-speed”.
Q.    Can Cisco Catalyst 2960-X switches and 2960-XR switches stack together?
A.     No. Cisco Catalyst 2960-X and 2960-XR switches can’t be stacked together, even though they belong to the same 2960-X series they do not share same IOS License models.
Q.    What are the possible mixed-stack combinations?
A.     The LAN Base models can only form mixed stacks. The possible mixed-stack combinations are listed in Table 5.

Q.    Which SDM template should be selected on the Cisco Catalyst 2960-X Series with LAN Base to form a mixed stack with Cisco Catalyst 2960-S?
A.     If Cisco Catalyst 2960-S is running the “default” SDM template, then Cisco Catalyst 2960-X must use the “default” template. If Cisco Catalyst 2960-S is running the “lanbase-routing” template, then Cisco Catalyst 2960-X must use the same.
Q.    Can Cisco Catalyst 2960-S be the stack master in a mixed stack of 2960-S and 2960-X switches?
A.     Yes. Cisco Catalyst 2960-S can be stack master in a mixed stack.
Q.    In a mixed stack of Cisco Catalyst 2960-S and 2960-X, must all the switches be on the same Cisco IOS Software release?
A.     Yes. All the switches in the stack, regardless of model, must be on the same Cisco IOS Software release. This includes the rebuild number. The minimum Cisco IOS Software release that will support both 2960-S and 2960-X is 15.0(2)EX.
Q.    Can we use FlexStack stacking modules with Cisco Catalyst 2960-X Series?
A.     No. The form factors of FlexStack-Plus and FlexStack modules are different. The FlexStack stacking module cannot be used with the Cisco Catalyst 2960-X Series. Similarly, the FlexStack-Plus module cannot be used with the Cisco Catalyst 2960-S Series.

Energy Efficiency

Q.    How much power can be saved with energy efficiency features in the Cisco Catalyst 2960-X Series?
A.     Catalyst 2960-X Series introduced new innovative energy saving modes for the switch.

   The Switch Hibernation Mode puts the switch to sleep when the switch is not in use. This feature enables the switch to save up to 90% of power during non-business hours.

   Downlink Hibernation Mode powers down the PHY and the optics of the downlink port when not in use.

   Energy Efficient Ethernet (EEE) enables dynamic power savings on all switch ports; saves about 15W for a 48port-switch and 8W for a 24 port-switch.

   EnergyWise Puts IP End Points in Energy Saver mode, saving 60%+ power with non-active IP devices.

The collective power savings with different energy efficient technologies will reduce the power consumption by up to 80%.
Q.    What is Downlink Hibernation Mode in the Cisco Catalyst 2960-X Series?
A.     Downlink Hibernation Mode (DHM) feature enables all 2960-X switches to save power on the downlink ports. The switch supports static downlink port power-down where only the PHY and Optics are powered down when not in use.
Q.    What is switch hibernation mode in the Cisco Catalyst 2960-X Series?
A.     When the switch is not in use, switch hibernation mode can be scheduled to save power. When the switch is in hibernation mode, it powers off application-specific integrated circuits (ASICs), and connected PoE devices. Power to most of the components is off. The DRAM is in refresh mode, keeping data intact. The switch hibernation mode is integrated with EnergyWise.
Q.    Is a Cisco Catalyst 2960-X Series Switch usable while in hibernation mode?
A.     No. All hardware components on the data path are switched off on Cisco Catalyst 2960-X Series Switches during hibernation mode.
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.

Switch Architecture

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

   10/100 Ethernet management port

Q.    Can both USB Type B console and RJ-45 console ports be used simultaneously?
A.     No. Only one can be used for input, but both can receive output. When the USB console is connected, “it is used for input (by default)”. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.
Q.    Does the switch support auto-baud on the console port?
A.     No. This was a tradeoff between console speed sensing and the ability to use the USB console.
Q.    Which management port has priority?
A.     The RJ-45 console port is always the default management port, but when a PC is connected to the USB console port, the USB console takes over. The RJ-45 port continues to receive the output (a copy) of everything that gets displayed on the USB console port. This capability allows remote administrators to continue monitoring or logging the output showing what is happening at the switch location, sending it to a storage device.
Q.    When a PC is left unattended on the USB console port, would remote administrators get locked out from the RJ-45 management port?
A.     The USB console port has a default activity timer that can also be programmed by the user. This activity timer will expire and return control to the RJ-45 management port to avoid locking the remote administrator out.
Q.    What can I do with the USB Type A port of the Cisco Catalyst 2960-X Series?
A.     It is used to connect to an external USB memory drive for additional storage. This USB port can be used to perform software upgrades, store configurations, and even write memory core dumps for troubleshooting purposes. All Cisco USB memory drives can be used. Currently up to 8-GB USB drives are supported.
Q.    Can a third-party USB Flash drive be used with the Cisco Catalyst 2960-X Series?
A.     Yes, a third-party USB Flash drive can be used with the Cisco Catalyst 2960-X Series. They will work, but are not officially supported.
Q.    What is the performance of the Cisco Catalyst 2960-X Series Switches?
A.     The Cisco Catalyst 2960-X Series have a nonblocking switching architecture capable of forwarding traffic for all 48 1 Gigabit ports plus 2 10 Gigabit ports at line rate. See the datasheet for the MPPS information for each model.
Q.    Do the Cisco Catalyst 2960-X Series Switches consume less power than the Cisco Catalyst 2960-S Series Switches?
A.     The Cisco Catalyst 2960-X Series are based on the same building blocks as the 2960-S-Series Switches for most components. However, these switches have a new thermal design, new highly efficient power supplies, and new efficient fans, which use less power.
Q.    Do the Cisco Catalyst 2960-X Series Switches support front-to-back airflow?
A.     The airflow on the Cisco Catalyst 2960-X Series is “front and sides” to back airflow.
Q.    Is the airflow reversible in the Cisco Catalyst 2960-X Series Switches?
A.     No. The airflow is not reversible.
Q.    Do Cisco Catalyst 2960-X Series Switches support field-replaceable power supplies?
A.     Cisco Catalyst 2960-XR switch models have field replaceable power supplies, whereas the 2960-X switch models have fixed power supplies.
Q.    Are Cisco Catalyst 2960-XR field-replaceable power supplies hot swappable?
A.     Yes. Cisco Catalyst 2960-XR power supplies are hot swappable.
Q.    Can a non-PoE Cisco Catalyst 2960-X Series Switch support PoE by replacing its power supply with a PoE-capable power supply?
A.     No. A non-PoE Cisco Catalyst 2960-X Series Switch will not support PoE by using a PoE-capable power supply.
Q.    Can we increase the PoE budget of Cisco Catalyst 2960-X Series Switch by replacing its power supply with a high-capacity power supply?
A.     The available PoE budget is fixed for a given model of Cisco Catalyst 2960-X Series Switch. Replacing the switch power supply will not increase the PoE budget.
Q.    Do I need two power supplies to run a Cisco Catalyst 2960-XR Series Switch?
A.     No. The Cisco Catalyst 2960-XR Series Switches support two field-replaceable power supplies to provide redundancy. The power supplies are in shared mode. Three power supply options are available for use in the Cisco Catalyst 2960-XR Series, as shown in Table 6.

Intelligent Services

Q.    What is NetFlow-Lite?
A.     The Cisco Catalyst 2960-X Series supports hardware-driven NetFlow-Lite. NetFlow-Lite uses sampled flows to provide statistics for network traffic accounting, network monitoring, and network planning. A flow is created using a flow record, which defines the unique keys of the flow. NetFlow-Lite provides valuable information about network users and applications, peak usage times, and traffic routing.
Q.    Is NetFlow-Lite supported on all Cisco Catalyst 2960-X Series models?
A.     NetFlow-Lite is not supported on LAN Lite models. It is supported on LAN Base and IP Lite models of the Cisco Catalyst 2960-X Series.
Q.    Is NetFlow-Lite supported on all ports of the Cisco Catalyst 2960-X Series?
A.     NetFlow-Lite is natively supported on all downlink and uplink ports of the Cisco Catalyst 2960-X Series. No service module is required to support NetFlow-Lite on the Cisco Catalyst 2960-X Series.
Q.    Is NetFlow-Lite supported on mixed stacks?
A.     Yes, NetFlow-Lite is supported on mixed stacks (stacks of Cisco Catalyst 2960-S and 2960-X Series Switches). But NetFlow-Lite monitor can be attached only on Cisco Catalyst 2960-X Series ports.
Q.    Which version of NetFlow exporters is supported?
A.     Only NetFlow Version 9 is supported for NetFlow exporter using the export-protocol command option.
Q.    How many NetFlow-Lite flows are supported on the Cisco Catalyst 2960-X Series?
A.     16K NetFlow-Lite flows are supported on a stack of Cisco Catalyst 2960-X Series Switches.
Q.    Is egress flow monitor supported on the Cisco Catalyst 2960-X Series?
A.     No, only ingress flow monitors are supported on the Cisco Catalyst 2960-X Series.
Q.    Can the flow monitors be attached to logical interfaces on the Cisco Catalyst 2960-X Series?
A.     The flow monitors can be attached to physical interfaces and VLAN interfaces (SVI) on the Cisco Catalyst 2960-X Series. The flow monitor can’t be attached to logical interfaces such as EtherChannel or Layer 2 VLANs.
Q.    If flow monitors are attached on both the physical port and VLAN interface, which one will take precedence in the Cisco Catalyst 2960-X Series?
A.     The interface VLAN monitor will overwrite the port monitor for the traffic coming on the port in the Cisco Catalyst 2960-X Series.
Q.    Can we have NetFlow-Lite monitor attached without sampling?
A.     No, only sampled NetFlow-Lite monitors can be attached on the Cisco Catalyst 2960-X Series.
Q.    What sampling modes are supported on the Cisco Catalyst 2960-X Series?
A.     Two sampling modes are supported on the Cisco Catalyst 2960-X Series:

   Deterministic sampler is dedicated to single attachment. It always makes sure the correct number of flows is sampled on the attached port. Every attachment with same deterministic sampler uses one free sampler available in the hardware.

   Random sampler is shared among all the attached interfaces. Only the first attachment uses a new sampler; subsequent attachments of the same sampler on different interfaces share the same hardware sampler.

Q.    How many different NetFlow-Lite samplers are supported by the hardware in the Cisco Catalyst 2960-X Series?
A.     The Cisco Catalyst 2960-X Series supports four different NetFlow-Lite samplers in the hardware.
Q.    Can we have deterministic sampler attached on more than four interfaces on the Cisco Catalyst 2960-X Series?
A.     No. Because each deterministic sampler attachment uses up one free hardware sampler, a deterministic sampler can’t be attached to more than four interfaces. It is recommended to use random sampler if the flows needs to be monitored on more than four ports.

PoE Support (IEEE 802.3af and 802.3at)

Q.    Do the Cisco Catalyst 2960-X Series PoE switches support the IEEE 802.3af or 802.3.at standards?

Q.    Can the Cisco Catalyst 2960-X Series PoE switches detect Type 1 and Type 2 powered devices?
A.     The Cisco Catalyst 2960-X Series supports both the PoE and PoE+ standards and can classify a powered device as either Type 1 or 2 with a one-event classification. A Type 2 powered device supports Class 4 in order to obtain more power than is supported by the legacy power levels (30W). A Type 1 powered device can support only up to Class 3, or 15.4W.
Q.    Can the Cisco Catalyst 2960-X Series PoE switches support two-event classification?
A.     No. Two-event classification is specific to mid spans that work on power-supplying equipment (PSE). The Cisco Catalyst 2960-X Series supports only one-event classification.
Q.    Do the Cisco Catalyst 2960-X Series PoE switches support power classification?
A.     Yes, the Cisco Catalyst 2960-X Series Switches can optionally detect the powered device power classification signature and budget the appropriate power. This reduces the maximum power that must be budgeted by the switch and provisioned in the wiring closet.
Q.    What is the maximum power per port that the Cisco Catalyst 2960-X Series PoE switches can supply?
A.     The Cisco Catalyst 2960-X Series supports both PoE standards, 802.3af and 802.3at, which define the maximum power that can be supplied to a port. The switches can provide up to 30W per port.
Q.    To how many end devices can the Cisco Catalyst 2960-X Series provide PoE and PoE+?
A.     The Cisco Catalyst 2960X-48FPD-L and C2960X-48FPS-L can support 48 PoE ports with full Class 3 PoE power of 15.4W each, for a total output capacity of 740W. All Cisco Catalyst 2960-X Series Switches with PoE capability support PoE+. A complete list of Cisco Catalyst 2960-X and 2960-XR switches, with their PoE capacities, is given in Table 10.
