PoE Powered and PoE Pass-Through

Q. What is the difference between Power over Ethernet (PoE) powered and PoE pass-through?
A. PoE powered is the capability of the switch to power using PoE, PoE+, or UPoE from its uplinks. PoE pass-through is the capability of the switch to supply PoE on the downlink ports. PoE available for PoE pass-through is the PoE drawn from the uplink port’s (switch consumption) internal losses.
Q. Which switches support PoE/PoE+ powered and PoE pass-through?
A. The 2960CPD-8PT-L can be PoE powered and supply PoE pass-through on downlinks. The 3560CPD-8PT-L is PoE+ powered and provides PoE pass-through on downlinks.
Q. Are there any switches that are PoE powered but are not PoE pass-through?
A. 2960CPD-8TT-L is PoE powered, but does not support PoE pass-through on downlinks.
Q. What are the various ways of powering the 2960-C and 3560-C models of compact switches?
A. Some models of the Cisco Catalyst 2960-C and 3560-C Series Switches can be powered using the built-in AC power supply. Others can be powered using the PoE uplinks or the auxiliary input using a power adapter. Switches support either the AC power or the PoE-powered capability with auxiliary. The same switch cannot be powered using AC power and PoE power/auxiliary power. (See Table 5.)

Q. What is PoE pass-through?
A. PoE pass-through is the capability of the PoE/PoE+-powered switch to supply PoE on the downlink ports. PoE available for PoE pass-through is the PoE drawn from the uplink port’s (switch consumption) internal losses. 2960CPD-8PT-L supports PoE pass-through.
Q. Can the compact switches provide PoE on the downlink ports or PoE pass-through?
A. Yes. Both 2960-C and 3560-C Series Switches have models that are PoE capable and that support PoE pass-through.
Q. How much PoE power is available on the downlink ports in 2960-C and 3560-C Series Switches?
A. Available PoE power for downlink ports depends on the powering mode. If the switches are powered using a built-in AC power supply such as the 3560CG-8PC-S, then the available PoE budget is 124 watts. If the switch is PoE powered on the uplinks or uses the auxiliary power supply, the values are as shown in Tables 6, 7, and8.

Q. Are the 2960-C and 3560-C switches capable of providing PoE+ on the downlinks?
A. The 3560-C Series Switch is capable of providing PoE+ on the downlink ports.
Q. Can I power the switch using both the uplink PoE/PoE+ and aux power input to get a higher PoE budget?
A. No. When both auxiliary and PoE uplinks are connected, the aux power input takes precedence for redundancy purposes.
Q. Can I power the switch using any combination of PoE and PoE+ on the uplink ports? For example, can one uplink be powered using PoE and the other being powered using PoE+?
A. Yes. A PoE-powered switch can accept any combination of PoE and PoE+.
Q. To what uplink switches can the compact switch connect to get PoE/PoE+ power?
A. The compact switches can connect to any of the IEEE-compliant PoE/PoE+ switches such as the Cisco Catalyst 3750-X Series or 2960-S Series Switches. PoE+ capable switches will provide more PoE budget on the downlinks as compared to the PoE-capable switches.
Q. What happens to the PoE-powered devices on the downlink ports on the 2960CPD-8PT- L and 3560CPD-8PT-S when one of the uplinks gets disconnected?
A. If one of the uplink ports gets disconnected, the available PoE budget for the downlink ports is reduced. Under such circumstances the switch performs intelligent load shedding. Devices that need less PoE than the available PoE budget are serviced, starting from the lowest numbered port to the highest numbered port. Devices that need more PoE than the available PoE budget may/will lose power. In case of the 3560CPD-8PT-S, when one of the PoE+ uplinks is lost, the PoE budget reduces to 0. As a result any PoE devices connected on the downlink ports will stop receiving PoE from the switch.
Q. When powering a switch using uplink PoE/PoE+, what is the maximum length of the CAT5/CAT6 cable that I can use on the uplinks to help make sure that the documented PoE budget is available?
A. To make sure that the compact switch gets the desired PoE, the cable connecting the compact switch and the uplink switch should not exceed 100 meters in length as per the IEEE specification for PoE cabling.

Security and MACSec

Q. How can I keep unauthorized users from accessing my network?
A. The Cisco Catalyst 2960-C and 3560-C Series Switches support the IEEE 802.1X standard, which works in conjunction with a RADIUS server to authenticate users as they access a network. Additionally, portions of the network can be restricted by using access control lists (ACLs). Access can be denied based on MAC addresses, IP addresses, or TCP/User Datagram Protocol (UDP) ports. ACL lookups are done in hardware and do not compromise forwarding and routing performance. An additional protection method is to use port security, which helps ensure that the appropriate user is on the network by limiting access to the port based on MAC addresses.
In addition to this, the authenticated users on a 3560-C switch can also establish an encrypted session with the switch using MACSec (IEEE 802.1ae) if the user device is MACSec capable.
Q. How can I monitor or track activities in my network?
A. The Cisco Catalyst 2960-C and the 3560-C Series Switches can complement an intrusion detection system (IDS) or firewall with features such as MAC address notification, which sends an alert to a management station, so that network administrators know when and where users come onto the network and can take appropriate action. The Dynamic Host Configuration Protocol (DHCP) Interface Tracker (option 82) feature tracks where a user is physically connected on a network by providing both switch and port ID to a DHCP server. DHCP snooping enables the administrator to keep track of both dynamic and static IP/MAC mapping tables.
Q. How can I protect administration passwords and traffic going to the switch during configuration or troubleshooting?
A. To protect administration traffic during the configuration or troubleshooting of a switch (such as passwords or device configuration settings), the best approach is to encrypt the data using both Secure Shell Protocol (SSH) and Simple Network Management Protocol (SNMP) v3 to provide encryption of data during Telnet sessions and SNMP sessions.
Q. Is MACSec supported on the 2960-C and the 3560-C switch models?
A. Yes. MACSec (IEEE 802.1ae) is supported on the 3560-C Series Switches on the downlinks to MACSec-capable clients. MACSec is not supported on the 2960-C Series.
Q. What infrastructure do I need to set up MACSec with the compact switches?
A. A MACSec-capable Cisco Catalyst switches (Cisco Catalyst 3560-C Series, ACS server) version 5.1 and AnyConnect version 3.0 supplicant on end-user workstations (laptops, desktops) are needed.

Network Management

Q. What network management applications support Cisco Catalyst 2960-C and 3560-C Series Switches?
A. The following Cisco network management applications can be used to manage the Cisco Catalyst 2960-C and 3560-C Series Switches.

CiscoWorks LAN Management Solution bundle (LMS) 4.1: More information on LMS can be found on Cisco.com at http://www.cisco.com/go/lms.

Q. Can you describe how CiscoWorks LAN Management System (LMS) manages Cisco Catalyst 2960-C and 3560-C Series Switches?
A. CiscoWorks LAN Management Solution (LMS) is an integrated suite of management functions that simplify the configuration, administration, monitoring, and troubleshooting of Cisco networks. CiscoWorks LMS allows network operators to manage the network through a browser-based interface that can be accessed any time from anywhere within the network.
Once installed, “out-of-the-box” monitoring and troubleshooting dashboards provide actionable information to quickly isolate and fix network problems before they affect services. Configuring and deploying updates to the network can be accomplished using the Template Center, which incorporates Cisco Validated Designs and links to download the latest configuration templates from Cisco.com, simplifying platform and technology deployment and reducing the chance for errors. “Work Centers” provide a single area where guided workflows give step-by-step instructions to help operators quickly provision, monitor, and manage new Cisco value-added technologies and solutions, such as EnergyWise, TrustSec/Identity, Auto Smartports, and Smart Install.

Features

Q. Does the Cisco Catalyst 2960-C or 3560-C have a front panel out-of-band (OOB) Ethernet management interface?
A. No. The Cisco Catalyst 2960-C and 3560-C Series do not support the OOB Ethernet management interface.
Q. What is the function of the reset button on the rear of the compact switch?
A. Pressing the reset button power cycles the switch, saving the startup configuration.
Q. What are the enhancements to the light-emitting diodes (LEDs) on the front panel?
A. There is a new LED called PD. This LED applies to 3560CPD-8PT-S, 2960CPD-8PT-L, and 2960CPD-8TT-L. Solid green on the PD LED indicates that uplink PoE is applied and is sufficient to power the system. Solid amber indicates that the uplink PoE is applied and is insufficient to power the system. Unlike other LEDs, the PD LED is not under the control of the mode button. It is controlled by the PoE subsystem in the switch and is always representative of the current power sources.
Q. Is a USB miniconsole available for switch CLI access on the 2960-C and 3560-C Series Switches?
A. Yes.
Q. Because the compact switches do not have a fan for cooling, what are the best practices for mounting the switch in a closet/under the table/other closed environments?
A. Airflow around the switch should be unrestricted. Best practices allow for at least 3 inches (7.6 cm) of clearance on all sides and ventilation openings. Allow at least 1.75 inches (4 cm) of clearance above each switch if placed in a rack. Clearance to the front and rear panels should allow you to easily read the front-panel indicators. Access to ports should be sufficient for unrestricted cabling. The rear-panel power connector should be within reach of an AC power receptacle. The 2960-C is rated to 113°F (45°C), and therefore it is important to make sure that the temperature around the unit does not exceed 113°F (45°C).
It is recommended that when wall-mounting the switch, it be oriented with the ports facing either left, right, or down.
Q. What types of Small Form-Factor Pluggable (SFP) modules are supported by the Cisco Catalyst 2960-C and 3560-C Series Switches?
A. Cisco Catalyst 3560-C and 2960-C Series Switches support the same set of SFPs. There are limitations to the SFP types supported. (See Table 10.)
