DHCPv6 Address

Displays the DHCP IPv6 address.

Static IP (IPv4/IPv6)

Check box to enable configuration of the AP using static IP address. From Release 8.0, IPv4 and IPv6 are supported.

Static IP (IPv4/IPv6)

Static IP address of the access point.

When an access point boots up, it tries to determine if its static IP address is configured or not. If the access point has been configured with a static IP address that is not valid on the network, the access point cannot join the controller and cannot communicate with the rest of the network. In such a scenario, the only way to recover that access point is to manually open the access point door and connect a serial console for configuration purpose.

The access point can be configured in such a way that, even if its static IP address is not valid on the network, it initiates a DHCP process to get a new IP address and use it for communication. This configuration enables the access point to join the controllers on the network.

Note An access point cannot discover the controller using domain name system (DNS) resolution if a static IP address is configured for the access point, unless you specify a DNS server and the domain to which the access point belongs.

Options for this parameter are as follows:

• Unselected—When this check box is not selected, the static IP address is disabled and the access point initiates a DHCP process when it boots up to procure the IP address.
• Checked—When this check box is selected, you can set the following:

– The static IPv4/IPv6 address of the access point.

– The subnet mask/ prefix length assigned to the access point IPv4/IPv6 address.

– The IPv4/IPv6 gateway of the access point.

Click Apply to commit your changes. The access point reboots and rejoins the controller, and the static IP address that you specified in is sent to the access point. You can now configure the DNS server IP address and domain name. To do so, follow these steps:

– In the DNS IP Address text box, enter the IPv4/IPv6address of the DNS server.

– In the Domain Name text box, enter the name of the domain to which the access point belongs.

Click Apply to commit your changes.

FlexConnect Mode Supported

Whether the access point can be configured as a remote edge lightweight access point. The values are Yes or No.

FlexConnect Mode is supported on the 1130AG, 1240AG, and 1250 access points.

Note By default, a VLAN is not enabled on the FlexConnect. After it is enabled, FlexConnect inherits the VLAN name (interface name) and VLAN ID associated to WLANs. This configuration is saved in the access point and received after the successful join response. By default, no VLAN is set as a native VLAN. There must be one native VLAN configured per REAP in a VLAN-enabled domain. Otherwise, REAP cannot send packets to or receive packets from the controller. When the client gets assigned a VLAN from the RADIUS server for the client, that VLAN is associated to the local switched WLAN.

Note Black list—FlexConnect supports the first 128 entries in the list in the standalone mode.

AP Role

Root AP or Mesh AP.

Root APs have a wired CAPWAP (Control and Provisioning of Wireless Access Points) protocol connection back to a controller. This connection uses the backhaul wireless interface to communicate to neighboring Mesh APs. Root APs are parent nodes to any bridging or mesh network and connect a bridge or mesh network to the wired network. You can have only one Root AP for any bridged or mesh network.

Mesh APs have no wired connection to a controller. They can be completely wireless supporting clients, communicating to other Mesh APs and a Root AP to get access to the network, or they can be wired and serve as a bridge to a remote wired network.

Bridge Type

(Display Only Field) Whether the access point is an indoor or outdoor access point.

Bridge Group Name

Bridge group name.

Use bridge group names to logically group the access points and to avoid two networks on the same channel from communicating with each other.

Note For the access points to communicate with each other, they must have the same bridge group name.

Ethernet Bridging

Ethernet bridging on the access point.

If the AP Mode is Root AP, Ethernet bridging is enabled by default.

If the AP Mode is Mesh AP, Ethernet bridging is disabled by default.

Enable Ethernet bridging on a Mesh AP if you want to do one of the following:

• Use the mesh nodes as bridges.
• Connect an Ethernet device on the Mesh AP using its Ethernet port.

Note When you enable Ethernet Bridging and click Apply, the Ethernet Bridging Parameters area appears and lists the four Ethernet ports of the mesh access point.

Backhaul Interface

(Display Only Field) Backhaul interface (802.11a, 802.11b, 802.11g, or 802.11n).

Bridge Data Rate (Mbps)

Rate at which data is shared between the access points. The drop-down list displays the data rates depending on the Backhaul Interface set.

The correct range of values depend on the backhaul interfaces used by the access points.

The data rates (Mbps) are as follows:

• 802.11a: auto, 6, 9, 12, 18, 24, 36, 48, 54

Note In previous software releases, the default value for bridge data rate for 802.11a was 24 Mbps. In controller release 6.0, the default value for the bridge data rate is auto. If you configured the default bridge data rate value (24 Mbps) in a previous controller software release, the bridge data rate is configured with the new default value (auto) when you upgrade to controller software release 6.0. However, if you configured a nondefault value (for example, 18 Mbps) in a previous controller software release, that configuration setting is preserved when you upgrade to software release 6.0.

When the bridge data rate is set to auto, the mesh backhaul chooses the highest rate where the next higher rate cannot be used due to unsuitable conditions for that specific rate (and not because of conditions that affect all rates).

• 802.11b: 1, 2, 5.5, 11
• 802.11g: 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54

The setting is also useful if you have more than one RAP in your network in the same sector (area). The BGN can be a string of up to 10 characters.

Ethernet Bridging

Check box that you enable to configure Ethernet bridging. For security reasons, the Ethernet port on all MAPs is disabled by default. It can be enabled only by configuring Ethernet bridging on the root and its respective MAP. You must enable Ethernet bridging in the following scenarios:

• When you want to use the mesh nodes as bridges.
• When you want to connect any Ethernet device such as a video camera on the MAP using its Ethernet port. This is the first step to enable VLAN tagging.

Backhaul Interface

To associate an AP group VLAN with an access point, follow these steps:

1. Select an AP group VLAN from the drop-down list.

2. Click Apply.

For more information on creating a new AP group and mapping it to an interface, see the AP Groups page.

Statistics Timer

Time in seconds that the access point sends its 802.11 statistics to the Cisco WLC.

Data Encryption

Datagram Transport Layer Security (DTLS) data encryption that you can enable or disable. The default is unselected.

Cisco 5500 Series Wireless Controllers enable you to encrypt CAPWAP control packets (and optionally, CAPWAP data packets) that are sent between the access point and the controller using DTLS. DTLS is a standards-track Internet Engineering Task Force (IETF) protocol based on TLS. CAPWAP control packets are management packets exchanged between a controller and an access point while CAPWAP data packets encapsulate forwarded wireless frames. CAPWAP control and data packets are sent over separate UDP ports: 5246 (control) and 5247 (data). If an access point does not support DTLS data encryption, DTLS is enabled only for the control plane, and a DTLS session for the data plane is not established.

Note If an access point with data encryption enabled tries to join any other controller, the access point joins the controller, but data packets are sent unencrypted.

DTLS data encryption is enabled automatically for OfficeExtend access points but disabled by default for all other access points. Most access points are deployed in a secure network within a company building, so data encryption is not necessary. The traffic between an OfficeExtend access point and the controller travels through an unsecure public network, so data encryption is more important for these access points. When data encryption is enabled, traffic is encrypted at the access point before it is sent to the controller and at the controller before it is sent to the client.

Note Encryption limits throughput at both the controller and the access point, and maximum throughput is desired for most enterprise networks.

The availability of data DTLS for the 7.1 release is as follows:

• The Cisco 5500 Series Controller will be available with two licenses options. One that allows data DTLS without any license requirements and another image requiring a license to use data DTLS. The images for the DTLS and licensed DTLS images are as follows:

– Licensed DTLS—AS_5500_LDPE_x_x_x_x.aes

– Non licensed DTLS—AS_5500_x_x_x_x.aes

• Cisco 7500, 2500, WiSM2, WLC2—These platforms by default will not contain DTLS. To turn on data DTLS, a license must be installed. That is, these platforms will have a single image with data DTLS turned off. To use data DTLS you must have a license.

Note If your controller does not have data DTLS license and if the access point associated with the controller has DTLS enabled, the data path will be unencrypted.

The following are some of the guidelines when upgrading to or from a DTLS image:

• You cannot install a regular image (DTLS enabled) once a non-DTLS image is installed.
• You can upgrade from one licensed DTLS image to another licensed DTLS image.
• You can upgrade from a regular image (DTLS) to a licensed DTLS image in a two step process.
• You cannot upgrade from a licensed DTLS image to any regular image.

Rogue Detection

Rogue detection for individual access points that you can enable or disable. Rogue detection is enabled by default for all access points joined to the controller (except for OfficeExtend access points). The default is unselected.

AP Sub Mode

AP submode that displays wIPS if the access point is in Monitor mode (from the AP Mode drop-down list on the General Tab) and the wIPS submode is configured on the access point or None if the access point is in local/FlexConnect modes and wIPS submode is not configured.

Note wIPS ELM is not supported on 1130 and 1240 access points.

Telnet

Telnet or SSH connectivity on this access point. The default is unselected.

These protocols make debugging the access point easier, especially when the access point is unable to connect to the controller.

SSH

TCP Adjust MSS

Enables the configuration of the maximum segment size (MSS) for transient packets that traverse a router on a per AP basis.

From Release 8.0, the controller supports IPv6. Use the following Global TCP Adjust MSS values for:

• IPv4—Specify a value between 536 and 1363.
• IPv6—Specify a value between 1220 and 1331.

Note Any TCP MSS value that is below 1220 and above 1331 will not be effective for CAPWAP v6 AP

UDP Lite

Displays the per AP UDP lite status.

Note The UDP Lite field is displayed only for APs that are associated using CAPWAP v6. This field is not displayed for APs associated using IPv4 address.

Disable LAN Ports

Parameter that makes the AP work only as a wireless AP.

Note This option is applicable only for Cisco 600 Series OfficeExtend Access Points.

Disable Personal SSID

Parameter that disallows users from setting up personal SSIDs.

Note This option is applicable only for Cisco 600 Series OfficeExtend Access Points.

Status that applies only to 1250 series access points that are powered using PoE.

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

Note There are two other ways to tell 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 Configuring 802.11a/n APs page. Second, the “PoE Status: degraded operation” message appears in the controller’s trap log on the Trap Logs page.

Pre-Standard State

Whether the access point is being powered by a high-power Cisco switch.

Unselect the check box if power is being provided by a power injector.

This option is disabled by default.

Power Injector State

Whether the attached switch supports intelligent power management (IPM) and a power injector is being used. If the attached switch supports IPM, you do not need to select this check box.

Power Injector Selection

One of the following options:

• Installed—Select the check box if you want the access point to examine and remember the MAC address of the currently connected switch port (this selection assumes that a power injector is connected).

If you want to configure the switch MAC address, enter the MAC address in the Injector Switch MAC address text box.

• Override—Select the check box to enable the access point to operate in high-power mode without first verifying a matching MAC address.

Injector Switch MAC Address

MAC address of the connected switch port.

Note The File Compression parameter is not displayed for ODM access points.

Antenna

(Displayed if 11n is supported)

Specific antennae for the access point that you can enable or disable:

• A—Right antenna port
• B—Left antenna port
• C—Center antenna port
• D—Dua-band antenna

By default, all are selected. For example, to enable transmissions from antenna ports A and B and receptions from antenna port C, you should select the following check boxes: Tx: A and B and Rx: C.

Valid combinations are A, A+B, A+B+C, or A+B+C+D.

When you select a dual-mode antenna, you can apply only a single spatial 802.11n stream rate. The range is from MCS 0 to 7.

When you select two dual-mode antennae, you can apply only two spatial 802.11n stream rates: The range is from MCS 0 to 15.

You must enable two antennae for dual-band access points such as Cisco Aironet 1600 Series Access Point and Cisco Aironet 3600 Series Access Point.

(Displayed if 11n is not supported)

Select one of the following:

• Enable—Enables diversity on both the connectors.
• Right—Enables diversity for the Right (Connector B) antenna.
• Left—Enables diversity for the Left (Connector A) antenna.

Antenna Gain

Antenna gain.

If you have a high-gain antenna, enter a value that is twice the actual dBi value (see the Cisco Aironet Antenna Reference Guide for antenna dBi values). Otherwise, enter 0.

For example, if your antenna has a 4.4 dBi gain, multiply the 4.4 dBi by 2 and round down to enter only the whole number (8). The controller reduces the actual equivalent isotropic radiated power (EIRP) to make sure that the antenna does not violate your country's regulations.

Note This option is available only if the antenna type is set to external.

Sniff

Sniffer operation that you can enable or disable.

When enabled, the access point begins capturing and forwarding all the packets from the client on a specific channel to a remote machine that runs Airopeek or Wireshark (packet analyzers for IEEE 802.11 wireless LANs). The default value is disabled (or unselected).

Channel

Channel on which the access points sniffs for packets. The default value is 1.

Server IP Address

Channel Width¹

Set the RF channel Assignment Method to Custom, and select one of the following channel widths:

• 20 MHz—Enables the radio to communicate using only 20-MHz channels. Choose this option for legacy 802.11a radios, 20-MHz 802.11n radios, or 40-MHz 802.11n radios that you want to operate using only 20-MHz channels. This is the default value.
• 40 MHz—Enables 40-MHz 802.11n radios to communicate using two adjacent 20-MHz channels bonded together. The radio uses the primary channel that you choose from the Assignment Method drop-down list as well as its extension channel for faster throughput. Each channel has only one extension channel (36 and 40 are a pair, 44 and 48 are a pair, and so on). For example, if you choose a primary channel of 44, the controller would use channel 48 as the extension channel. If you choose a primary channel of 48, the controller would use channel 44 as the extension channel.
• 80 MHz—Enables the radio to communicate using 80-MHz channels. This option is supported only for 802.11ac capable radios. 802.11ac channelization uses four adjacent 20-MHz channels. From the drop-down list you can select the primary channel and based on the available channel pairing, appropriate secondary 20-MHz and secondary 40-MHz extension channels can be configured for the radio.

Note To select the channel width as 80-MHz, 802.11ac support must be enabled in WIRELESS > 802.11a/n/ac > High Throughput (802.11n/ac).

Assignment Method

Assignment method that you can choose:

• Global—Use this setting if you set the channel of the access point globally by the Cisco WLC.
• Custom—Use this setting if you set the channel locally. Choose a channel from the drop-down list.

Note The assignment method should be left at the global setting to enable the Cisco WLC to dynamically change the channel number based Radio Resource Management (RRM) directives.

For the Cisco 3600 Access Points with the 802.11ac module, channel and transmit power assignments are not supported in the custom mode. The 802.11ac radio inherits the channel and power assignments applied to the 802.11n radio. When the assignment mode is custom, you can configure only the channel width settings on the 802.11ac radio.

Current Tx Power Level

(Display Only Field) Transmission power level of the access point. Tx Power Level indicates the maximum power.

Note The power levels and available channels are defined by the Country Code setting and are regulated on a country-by-country basis.

Assignment Method

Assignment method that you can choose:

• Global—Use this setting if you set the transmit power of the access point globally by the Cisco WLC.
• Custom—Use this setting if the transmit power of the access point is set locally. Choose an option from the drop-down list.

Note The assignment method should be left at the global setting to enable the Cisco WLC to dynamically change the transmit power level based on the Radio Resource Management (RRM).

Enable Tracking Optimization

• UP—The spectrum sensor for the access point radio is currently operational (error code 0).
• DOWN—The spectrum sensor for the access point radio is currently not operational because an error has occurred. The most likely reason for the error is that the access point radio is disabled (error code 8). To correct this error, enable the radio.
• ERROR—The spectrum sensor for the access point radio has crashed (error code 128), making CleanAir monitoring nonoperational for this radio. If this error occurs, reboot the access point. If the error continues to appear, you might want to disable CleanAir functionality on the radio.
• N/A—This access point radio cannot support CleanAir functionality. Currently, only Cisco Aironet 3500 series access point radios can be configured for Cisco CleanAir.

Note You can create a filter to make the 802.11a/n Radios page or the 802.11b/g/n Radios page show only access point radios that have a specific CleanAir status (such as UP, DOWN, ERROR, or N/A). This feature is especially useful if your list of access point radios spans multiple pages, preventing you from viewing them all at once. To create a filter, click Change Filter to open the Search AP page, select one or more of the CleanAir Status check boxes, and click Find. Only the access point radios that match your search criteria appear on the 802.11a/n Radios page or the 802.11b/g/n Radios page, and the Current Filter parameter at the top of the page specifies the filter used to generate the list (for example, CleanAir Status: UP).

RTS Threshold

Attribute that indicates the number of octets in an MPDU, below which an RTS/CTS handshake is not performed. An RTS/CTS handshake is performed at the beginning of any frame exchange sequence where the MPDU is of type Data or Management, the MPDU has an individual address in the Address1 field, and the length of the MPDU is greater than this threshold. Setting this attribute to be larger than the maximum MSDU size turns off the RTS/CTS handshake for Data or Management type frames transmitted by this STA. Setting this attribute to zero turns on the RTS/CTS handshake for all frames of Data or Management type transmitted by this STA. The default is 2347.

Short Retry Limit

Maximum number of transmission attempts of a frame, the length of which is less than or equal to dot11RTSThreshold, that is made before a failure condition is indicated. The default is 7.

Long Retry Limit

Maximum number of transmission attempts of a frame, the length of which is greater than dot11RTSThreshold, that is made before a failure condition is indicated. The default is 4.

Fragmentation Threshold

Current maximum size, in octets, of the MPDU that may be delivered to the PHY. An MSDU is broken into fragments if its size exceeds the value of this attribute after adding MAC headers and trailers. An MSDU or MMPDU is fragmented when the resulting frame has an individual address in the Address1 field, and the length of the frame is larger than this threshold. The default value for this attribute is the lesser of 2346 or the aMPDUMaxLength of the attached PHY and will never exceed the lesser of 2346 or the aMPDUMaxLength of the attached PHY. The value of this attribute is never be less than 256.

Max. Tx MSDU Lifetime

Elapsed time in TU, after the initial transmission of an MSDU, after which further attempts to transmit the MSDU is terminated. The default value is 512.

Max Rx Life Time

Elapsed time in TU, after the initial reception of a fragmented MMPDU or MSDU. Further attempts to reassemble the MMPDU or MSDU are terminated. The default is 512.

CleanAir Admin Status

Administration status of the spectrum sensor for the access point.

CleanAir Oper Status

Status of the spectrum sensor for this access point. The CleanAir status is one of the following:

• UP—The spectrum sensor for the access point radio is currently operational (error code 0).
• DOWN—The spectrum sensor for the access point radio is currently not operational because an error has occurred. The most likely reason for the error is that the access point radio is disabled (error code 8). To correct this error, enable the radio.
• ERROR—The spectrum sensor for the access point radio has crashed (error code 128), making CleanAir monitoring nonoperational for this radio. If this error occurs, reboot the access point. If the error continues to appear, you might want to disable CleanAir functionality on the radio.
• N/A—This access point radio cannot support CleanAir functionality. Currently, only Cisco Aironet 3500 series access point radios can be configured for Cisco CleanAir.

Note You can create a filter to make the Dual-Band Radios page show only access point radios that have a specific CleanAir status (such as UP, DOWN, ERROR, or N/A). This feature is especially useful if your list of access point radios spans multiple pages, preventing you from viewing them all at once. To create a filter, click Change Filter to open the Search AP page, select one or more of the CleanAir Status check boxes, and click Find. Only the access point radios that match your search criteria appear on the Dual-Band Radios page, and the Current Filter parameter at the top of the page specifies the filter used to generate the list (for example, CleanAir Status: UP).
