Power over Ethernet

This section contains the following subsections:

Configuring Power over Ethernet (GUI)

Procedure

Step 1

Choose Wireless > Access Points > All APs and then the name of the desired access point.

Step 2

Choose the Advanced tab to open the All APs > Details for (Advanced) page.

The PoE Status text box shows the power level at which the access point is operating: High (20 W), Medium (16.8 W), or Medium (15.4 W). This text box is not configurable. The controller auto-detects the access point’s power source and displays the power level here.

Note

 

This text box applies only to 1250 series access points that are powered using PoE. There are two other ways to determine if the access point is operating at a lower power level. First, the “Due to low PoE, radio is transmitting at degraded power” message appears under the Tx Power Level Assignment section on the 802.11a/n/ac (or 802.11b/g/n) Cisco APs > Configure page. Second, the “PoE Status: degraded operation” message appears in the controller’s trap log on the Trap Logs page.

Step 3

Perform one of the following:

  • Check the Pre-standard 802.3af switches check box if the access point is being powered by a high-power 802.3af Cisco switch. This switch provides more than the traditional 6 Watts of power but do not support the intelligent power management (IPM) feature.
  • Uncheck the Pre-standard 802.3af switches check box if power is being provided by a power injector. This is the default value.

Step 4

Check the Power Injector State check box if the attached switch does not support IPM and a power injector is being used. If the attached switch supports IPM, you do not need to select this check box.

Step 5

If you selected the Power Injector State check box in the previous step, the Power Injector Selection and Injector Switch MAC Address parameters appear. The Power Injector Selection parameter enables you to protect your switch port from an accidental overload if the power injector is inadvertently bypassed. Choose one of these options from the drop-down list to specify the desired level of protection:

  • Installed—This option examines and remembers the MAC address of the currently connected switch port and assumes that a power injector is connected. Choose this option if your network contains older Cisco 6-Watt switches and you want to avoid possible overloads by forcing a double-check of any relocated access points.

    If you want to configure the switch MAC address, enter the MAC address in the Injector Switch MAC Address text box. If you want the access point to find the switch MAC address, leave the Injector Switch MAC Address text box blank.

    Note

     

    Each time an access point is relocated, the MAC address of the new switch port fails to match the remembered MAC address, and the access point remains in low-power mode. You must then physically verify the existence of a power injector and reselect this option to cause the new MAC address to be remembered.

  • Override—This option allows the access point to operate in high-power mode without first verifying a matching MAC address. You can use this option if your network does not contain any older Cisco 6-W switches that could be overloaded if connected directly to a 12-W access point. The advantage of this option is that if you relocate the access point, it continues to operate in high-power mode without any further configuration. The disadvantage of this option is that if the access point is connected directly to a 6-W switch, an overload occurs.

Step 6

Click Apply.

Step 7

If you have a dual-radio 1250 series access point and want to disable one of its radios in order to enable the other radio to receive full power, follow these steps:

  1. Choose Wireless > Access Points > Radios > 802.11a/n//ac or 802.11b/g/n to open the 802.11a/n/ac (or 802.11b/g/n) Radios page.

  2. Hover your cursor over the blue drop-down arrow for the radio that you want to disable and choose Configure.

  3. On the 802.11a/n/ac (or 802.11b/g/n) Cisco APs > Configure page, choose Disable from the Admin Status drop-down list.

  4. Click Apply.

  5. Manually reset the access point in order for the change to take effect.

Step 8

Click Save Configuration.

Configuring Power over Ethernet (CLI)

Use these commands to configure and See PoE settings using the controller CLI:

  • If your network contains any older Cisco 6-W switches that could be accidentally overloaded if connected directly to a 12-W access point, enter this command:

    config ap power injector enable {Cisco_AP | all} installed

    The access point remembers that a power injector is connected to this particular switch port. If you relocate the access point, you must reissue this command after the presence of a new power injector is verified.


    Note
    Ensure CDP is enabled before entering this command. Otherwise, this command will fail.

  • Remove the safety checks and allow the access point to be connected to any switch port by entering this command:

    config ap power injector enable {Cisco_AP | all} override

    You can use this command if your network does not contain any older Cisco 6-W switches that could be overloaded if connected directly to a 12-W access point. The access point assumes that a power injector is always connected. If you relocate the access point, it continues to assume that a power injector is present.

  • If you know the MAC address of the connected switch port and do not want to automatically detect it using the installed option, enter this command:

    config ap power injector enable {Cisco_AP | all} switch_port_mac_address

  • If you have a dual-radio 1250 series access point and want to disable one of its radios in order to enable the other radio to receive full power, enter this command:

    config {802.11a | 802.11b} disable Cisco_AP


    Note
    You must manually reset the access point in order for the change to take effect.

  • See the PoE settings for a specific access point by entering this command:

    show ap config general Cisco_AP

    Information similar to the following appears:

    
Cisco AP Identifier.............................. 1
Cisco AP Name.................................... AP1
...
PoE Pre-Standard Switch.......................... Enabled
PoE Power Injector MAC Addr...................... Disabled
Power Type/Mode.................................. PoE/Low Power (degraded mode)
...


    The Power Type/Mode text box shows “degraded mode” if the access point is not operating at full power.

  • See the controller’s trap log by entering this command:

    show traplog

    If the access point is not operating at full power, the trap contains “PoE Status: degraded operation.”

  • You can power an access point by a Cisco prestandard 15-W switch with Power over Ethernet (PoE) by entering this command:

    config ap power pre-standard {enable | disable} {all | Cisco_AP}

    A Cisco prestandard 15-W switch does not support intelligent power management (IPM) but does have sufficient power for a standard access point. The following Cisco prestandard 15-W switches are available:

    • WS-C3550, WS-C3560, WS-C3750

    • C1880

    • 2600, 2610, 2611, 2621, 2650, 2651

    • 2610XM, 2611XM, 2621XM, 2650XM, 2651XM, 2691

    • 2811, 2821, 2851

    • 3631-telco, 3620, 3640, 3660

    • 3725, 3745

    • 3825, 3845

    The enable version of this command is required for full functionality when the access point is powered by a Cisco prestandard 15-W switch. It is safe to use if the access point is powered by either an IPM switch or a power injector or if the access point is not using one of the 15-W switches listed above.

    You might need this command if your radio operational status is "Down" when you expect it to be "Up." Enter the show msglog command to look for this error message, which indicates a PoE problem:
    

Apr 13 09:08:24.986 spam_lrad.c:2262 LWAPP-3-MSGTAG041: AP 00:14:f1:af:f3:40 is unable to 
verify sufficient in-line power. Radio slot 0 disabled.

Cisco Discovery Protocol

The Cisco Discovery Protocol (CDP) is a device discovery protocol that runs on all Cisco-manufactured equipment. A device enabled with CDP sends out periodic interface updates to a multicast address in order to make itself known to neighboring devices.

The default value for the frequency of periodic transmissions is 60 seconds, and the default advertised time-to-live value is 180 seconds. The second and latest version of the protocol, CDPv2, introduces new time-length-values (TLVs) and provides a reporting mechanism that allows for more rapid error tracking, which reduces downtime.


Note
We recommend that you disable Cisco Discovery Protocol on the controller and access point when connected to non-Cisco switches as CDP is unsupported on non-Cisco switches and network elements.

Restrictions for Cisco Discovery Protocol

  • CDPv1 and CDPv2 are supported on the following devices:

    • Cisco 3504 Wireless Controller

    • Cisco 5520 Wireless Controller

    • Cisco 8540 Wireless Controller

    • CAPWAP-enabled access points

  • The support of CDPv1 and CDPv2 enables network management applications to discover Cisco devices.

  • The following TLVs are supported by both the controller and the access point:

    • Device-ID TLV: 0x0001—The hostname of the controller, the access point, or the CDP neighbor.

    • Address TLV: 0x0002—The IP address of the controller, the access point, or the CDP neighbor.

    • Port-ID TLV: 0x0003—The name of the interface on which CDP packets are sent out.

    • Capabilities TLV: 0x0004—The capabilities of the device. The controller sends out this TLV with a value of Host: 0x10, and the access point sends out this TLV with a value of Transparent Bridge: 0x02.

    • Version TLV: 0x0005—The software version of the controller, the access point, or the CDP neighbor.

    • Platform TLV: 0x0006—The hardware platform of the controller, the access point, or the CDP neighbor.

    • Power Available TLV: 0x001a— The amount of power available to be transmitted by power sourcing equipment to permit a device to negotiate and select an appropriate power setting.

    • Full/Half Duplex TLV: 0x000b—The full- or half-duplex mode of the Ethernet link on which CDP packets are sent out.

  • These TLVs are supported only by the access point:

    • Power Consumption TLV: 0x0010—The maximum amount of power consumed by the access point.

    • Power Request TLV:0x0019—The amount of power to be transmitted by a powerable device in order to negotiate a suitable power level with the supplier of the network power.

  • If the switch has provided power through CDP, it continues to provide only with CDP, and vice-versa with LLDP. (CSCvg86156)

  • Changing the CDP configuration on the controller does not change the CDP configuration on the access points that are connected to the controller. You must enable and disable CDP separately for each access point.

  • You can enable or disable the CDP state on all or specific interfaces and radios. This configuration can be applied to all access points or a specific access point.

  • The following is the behavior assumed for various interfaces and access points:

    • CDP is disabled on radio interfaces on indoor (nonindoor mesh) access points.

    • Nonmesh access points have CDPs disabled on radio interfaces when they join the controller. The persistent CDP configuration is used for the APs that had CDP support in its previous image.

    • CDP is enabled on radio interfaces on indoor-mesh and mesh access points.

    • Mesh access points will have CDP enabled on their radio interfaces when they join the controller. The persistent CDP configuration is used for the access points that had CDP support in a previous image. The CDP configuration for radio interfaces is applicable only for mesh APs.

  • CDP over radio backhaul link is not supported in Wave 2 (COS) APs.

  • CDP is not supported in radio interfaces of Wave 2 (COS) APs. The GUI configuration of this has no effect.

  • LLDP is enabled on the APs by default and cannot be disabled.

Cisco 700 Series Access Points

The Cisco Aironet 700 Series is a compact access point that delivers secure and reliable wireless connections. The main features are:

  • Simultaneous dual band, dual radio with support for 2.4GHz and 5GHz.

  • Optimized antenna and radio designs: Consistent network transmit and receive for optimized rate versus range.

  • Radio resource management (RRM): Automated self-healing optimizes the unpredictability of RF to reduce dead spots and help ensure high-availability client connections.

  • Cisco BandSelect improves 5-GHz client connections in mixed-client environments.

  • Advanced security features including Rogue Detection, wIPS and Context-Aware.

Configuring Cisco 700 Series Access Points

The Cisco 700 series access points has four LAN ports. The configuration of these ports is stored in a file on flash. The AP retrieves the configuration when restarted. The AP then shares the information with Controller after joining so that Controller can display the updated information.


Note

The AP deletes the saved port information and applies the default configuration when the controller clears all the existing configuration on the AP. All LAN ports are disabled by default.

Enabling the LAN Ports (CLI)

Procedure

  • Enable or disable a LAN port on the access point by entering this command:

    config ap lan port-id port-id {enable | disable} ap-name

  • See the port information by entering this command:

    showap lan port-id port-id ap-name

  • See the port summary information by entering this command:

    showap lan port-summary ap-name
Enabling 702W LAN Ports

All ports are mapped to the same access VLAN that the AP's switch port is configured to. Alternatively, the ports are mapped to the native VLAN if port is a trunk. It is possible to enable or disable the ports and map them to specific VLANs if needed. This allows traffic to be separated not only between wireless and wired networks, but also among the four Ethernet ports.

Procedure

Step 1

Enable or disable a LAN port on the access point by entering this command:

config ap lan port-id port-id { enable | disable} ap-name

Step 2

Configure the port ID by entering this command:

config ap lan port-id port-id ap-name

Step 3

Configure VLAN for the AP by entering this command:

config ap lan enable access vlan vlan-id port-id ap-name

Remote LAN Support for Wired Ports on Cisco Aironet 702W APs

A remote LAN (RLAN) in Cisco Aironet 702W access points (APs) are used for authenticating wired clients using Cisco Wireless LAN Controller. You can set the various IEEE 802.1X authentication modes for the LAN ports in Cisco 702W APs by configuring them in RLAN.

The IEEE 802.1X authentication message exchange between a client and an authentication server is carried out locally in APs. All IEEE 802.1X configurations are carried out through controller. Both port control and restrictions are considered locally in APs.

Role of Controller

Controller acts as an authenticator, and Extensible Authentication Protocol (EAP) over LAN (EAPOL) messages from the wired client reaches controller through an AP, and controller communicates with the configured authentication, authorization, and accounting (AAA) server.

Role of an AP

An AP acts as a relay in tunneling the authentication packets from a wired client to controller using the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel. After a port is authenticated, the AP is responsible for port control and monitoring.

LAN ports for an AP are configured in controller and then pushed to the corresponding AP.

Initially, the AP configures the IEEE 802.1X port if the client that joins the AP passes the EAPOL packets to the controller.

IEEE 802.1X Authentication Modes

This topic describes the different IEEE 802.1X authentication modes.

Single-Host Mode

If the single-host authentication mode is configured in an AP and the port link state is up, the AP detects the client by sending the EAPoL frame. If the client leaves or is replaced with another client, the AP changes its port link state to down, making the port unauthorized.

The single-host configuration mode is configured using the existing RLAN configurations in the controller.

Multi-Host Mode

If the multi-host authentication mode is configured, only one client can be authenticated for all the clients to gain network access in that port. If the port becomes unauthorized, the switch denies access to all the attached clients.

Violation Mode

When a security violation occurs, a port is protected based on the following configured violation actions:

  • Shutdown—Disables the port.

  • Replace—Removes the current session and initiates authentication for the new host. This is the default behavior.

  • Protect—Drops packets with unexpected MAC addresses without generating a system message.

In the single-host authentication mode, a violation is triggered when more than one device is detected in data VLAN. In a multi-host authentication mode, a violation is triggered when more than one device is detected in data VLAN or voice VLAN.


Note

Security violation cannot be triggered in the multi-host authentication mode.

Configuring Preauthentication Open (CLI)

  • The preauthentication open option allows unrestricted traffic on an AP LAN port initially, and is restricted only by other access restrictions.

  • The preauthentication open feature is not supported in Cisco Aironet 1810 OEAPs.

Procedure

config remote-lan pre-auth {enable | disable} remote-lan-id vlan vlan-id

Example:
config remote-lan pre-auth enable 8 vlan vlan2

Configures preauthentication open on a VLAN.

Configuring IEEE 802.1X Authentication Modes (CLI)

You can configure three different authentications modes:

  • Single-host

  • Multi-host

  • Violation-mode

Procedure

Perform one of the following tasks to configure authentication:

  • config remote-lan host-mode singlehost remote-lan-id

    Example: 

    (Cisco Controller) > config remote-lan host-mode singlehost 7

    Configures a remote LAN single-host mode. In single-host mode, violation is triggered when more than one device is detected in data VLAN.

  • config remote-lan host-mode multihost remote-lan-id

    Example: 

    (Cisco Controller) > config remote-lan host-mode multihost 8

    Configuresa remote LAN multi-host mode. In multi-host mode, a violation is triggered when more than one device is detected in data or voice VLAN. Note that security violation cannot be triggered in multi-host mode.

  • config remote-lan violation-mode {protect | replace | shutdown}remote-lan-id

    Example: 

    (Cisco Controller) > config remote-lan violation-mode protect 7

    Configures violation mode for remote LAN.
