System Configuration

Information About New Configuration Model

The configuration of Cisco Embedded Wireless Controller on Catalyst Access Points is simplified using different tags, namely rf-tag, policy-tag, and site-tag. The access points would derive their configuration from the profiles that are contained within the tags.

Profiles are a collection of feature-specific attributes and parameters applied to tags. The rf-tag contains the radio profiles, the policy-tag contains the WLAN profile and policy profile, and the site-tag contains the flex profile and ap-join profile.

Policy Tag

The policy tag constitutes mapping of the WLAN profile to the policy profile. The WLAN profile defines the wireless characteristics of the WLAN. The policy profile defines the network policies and the switching policies for the client (Quality of Service [QoS] is an exception which constitutes AP policies as well).

The policy tag contains the map of WLAN policy profile. There can be a maximum of 16 such entries per policy tag. Changes to the map entries are effected based on the status of the WLAN profile and policy profile. For example, if a map (WLAN1 and Policy1) is added to the policy tag, and both the WLAN profile and the policy profile are enabled, the definitions are pushed to the APs using the policy tag. However, if one of them is in disabled state, the definition is not pushed to the AP. Similarly, if a WLAN profile is already being broadcast by an AP, it can be deleted using the no form of the command in the policy tag.

Site Tag

The site tag defines the properties of a site and contains the flex profile and the AP join profile. The attributes that are specific to the corresponding flex or remote site are part of the flex profile. Apart from the flex profile, the site tag also comprises attributes that are specific to the physical site (and hence cannot be a part of the profile that is a reusable entity). For example, the list of primary APs for efficient upgrade is a part of a site tag rather than that of a flex profile.

If a flex profile name or an AP profile name is changed in the site tag, the AP is forced to rejoin the controller by disconnecting the Datagram Transport Layer Security (DTLS) session. When a site tag is created, the AP and flex profiles are set to default values (default-ap-profile and default-flex-profile).

RF Tag

The RF tag contains the 2.4 GHz and 5 GHz RF profiles. The default RF tag contains the global configuration. Both these profiles contain the same default values for global RF profiles for the respective radios.

Profiles

Profiles are a collection of feature-specific attributes and parameters applied to tags. Profiles are reusable entities that can be used across tags. Profiles (used by tags) define the properties of the APs or its associated clients.

WLAN Profile

WLAN profiles are configured with same or different service set identifiers (SSIDs). An SSID identifies the specific wireless network for the controller to access. Creating WLANs with the same SSID allows to assign different Layer 2 security policies within the same wireless LAN.

To distinguish WLANs having the same SSID, create a unique profile name for each WLAN. WLANs with the same SSID must have unique Layer 2 security policies so that clients can select a WLAN based on the information advertised in the beacon and probe responses. The switching and network policies are not part of the WLAN definition.

Policy Profile

Policy profile broadly consists of network and switching policies. Policy profile is a reusable entity across tags. Anything that is a policy for a client that is applied on an AP or controller is moved to the policy profile, for example, VLAN, ACL, QoS, session timeout, idle timeout, AVC profile, bonjour profile, local profiling, device classification, BSSID QoS, and so on. However, all the wireless-related security attributes and features on the WLAN are grouped under the WLAN profile.

Flex Profile

Flex profile contains policy attributes and remote site-specific parameters. For example, the EAP profiles that can be used when the AP acts as an authentication server for local RADIUS server information, VLAN-ACL mapping, VLAN name-to-ID mapping, and so on.

AP Join Profile

The default AP join profile values will have the global AP parameters and the AP group parameters. The AP join profile contains attributes that are specific to AP, such as CAPWAP, IPv4 and IPv6, UDP Lite, High Availability, Retransmit config parameters, Global AP failover, Hyperlocation config parameters, Telnet and SSH, 11u parameters, and so on.


Note


Telnet is not supported for the following Cisco AP models: 1542D, 1542I, 1562D, 1562E, 1562I, 1562PS, 1800S, 1800T, 1810T, 1810W,1815M, 1815STAR, 1815TSN, 1815T, 1815W, 1832I, 1840I, 1852E, 1852I, 2802E, 2802I, 2802H, 3700C, 3800, 3802E, 3802I, 3802P, 4800, IW6300, ESW6300, 9105AXI, 9105AXW, 9115AXI, 9115AXE, 9117I, APVIRTUAL, 9120AXI, 9120AXE, 9124AXI, 9124AXD, 9130AXI, 9130AXE, 9136AXI, 9162I, 9164I, and 9166I.


RF Profile

RF profile contains the common radio configuration for the APs. RF profiles are applied to all the APs that belong to an AP group, where all the APs in that group have the same profile settings.

Association of APs

APs can be associated using different ways. The default option is by using Ethernet MAC address, where the MAC is associated with policy-tag, site tag, and RF tag.

In filter-based association, APs are mapped using regular expressions. A regular expression (regex) is a pattern to match against an input string. Any number of APs matching that regex will have policy-tag, site tag, and RF tag mapped to them, which is created as part of the AP filter.

In AP-based association, tag names are configured at the PnP server and the AP stores them and sends the tag name as part of discovery process.

In location-based association, tags are mapped as per location and are pushed to any AP Ethernet MAC address mapped to that location.

Modifying AP Tags

Modifying an AP tag results in DTLS connection reset, forcing the AP to rejoin the controller. If only one tag is specified in the configuration, default tags are used for other types, for example, if only policy tag is specified, the default-site-tag and default-rf-tag will be used for site tag and RF tag.

Configuring a Wireless Profile Policy (GUI)

Procedure


Step 1

Choose Configuration > Tags & Profiles > Policy.

Step 2

On the Policy Profile page, click Add.

Step 3

In the Add Policy Profile window, in General tab, enter a name and description for the policy profile. The name can be ASCII characters from 32 to 126, without leading and trailing spaces. Do not use spaces as it causes system instability.

Step 4

To enable the policy profile, set Status as Enabled.

Step 5

In the WLAN Switching Policy section, choose the following, as required:

  • No Central Switching: Tunnels both the wireless user traffic and all control traffic via CAPWAP to the centralized controller where the user traffic is mapped to a dynamic interface/VLAN on the controller. This is the normal CAPWAP mode of operation.

  • Central Authentication: Tunnels client data to the controller, as the controller handles client authentication.

  • No Central DHCP: The DHCP packets received from AP are centrally switched to the controller and then forwarded to the corresponding VLAN based on the AP and the SSID.

  • Central Association Enable: When central association is enabled, all switching is done on the controller.

  • Flex NAT/PAT: Enables Network Address Translation(NAT) and Port Address Translation (PAT) mode.

Step 6

Time Management

The date and time of the system on EWC is configured when you run the initial wireless express setup wizard. You can change or configure the time from the GUI menu by choosing Administration > Time.

You can configure a Network Time Protocol (NTP) server to synchronize date and time, if it was not configured during the wireless express setup. Greenwich Mean Time (GMT) is used as the standard for setting the time zone on the controller. You can also update or add the specific NTP server to EWC.


Note


EWC APs do not track time when powered off. Therefore, we recommned you to configure NTP to keep a proper time across reboots on the EWC.

AP Filter

Introduction to AP Filter

The introduction of tags in the new configuration model in the Cisco Embedded Wireless Controller on Catalyst Access Points has created multiple sources for tags to be associated with access points (APs). Tag sources can be static configuration, AP filter engine, per-AP PNP, or default tag sources. In addition to this, the precedence of the tags also plays an important role. The AP filter feature addresses these challenges in a seamless and intuitive manner.

AP filters are similar to the access control lists (ACLs) used in the controller and are applied at the global level. You can add AP names as filters, and other attributes can be added as required. Add the filter criteria as part of the discovery requests.

The AP Filter feature organizes tag sources with the right priority, based on the configuration.

You cannot disable the AP filter feature. However, the relative priority of a tag source can be configured using ap filter-priority priority filter-name command.


Note


You can configure tag names at the PnP server (similar to the Flex group and AP group) and the AP stores and send the tag name as part of discovery and join requests.


Set Tag Priority (GUI)

Procedure


Step 1

Choose Configuration > Tags & Profiles > Tags > AP > Tag Source.

Step 2

Drag and Drop the Tag Sources to change priorities.


Set Tag Priority

Multiple tag sources might result in ambiguity for network administrators. To address this, you can define priority for tags. When an AP joins the controller, the tags are picked based on priority. If precedence is not set, the defaults are used.

Use the following procedure to set tag priority:

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters the global configuration mode.

Step 2

ap tag-source-priority source-priority source {filter | pnp}

Example:

Device(config)# ap tag-source-priority 2 source pnp

Configures AP tag source priority.

Note

 

It is not mandatory to configure AP filter. It comes with default priorities for Static, Filter, and PnP.

Step 3

end

Example:

Device(config)# end

Exits configuration mode and returns to privileged EXEC mode.

Step 4

ap tag-sources revalidate

Example:

Device# ap tag-sources revalidate

Revalidates AP tag sources. The priorities become active only after this command is run.

Note

 

If you change the priorities for Filter and PnP, and want to evaluate them, run the revalidate command.

Configuring Access Point for Location Configuration

Information About Location Configuration

During location configuration, you can perform the following:

  • Configure a site or location for an AP.

  • Configure a set of tags for this location.

  • Add APs to this location.

Any location comprises of the following components:

  • A set of unique tags, one for each kind, namely: Policy, RF and Site.

  • A set of ethernet MAC addresses that applies to the tags.

This feature works in conjunction with the existing tag resolution scheme. The location is considered as a new tag source to the existing system. Similar, to the static tag source.

Prerequisite for Location Configuration

If you configure an access point in one location, you cannot configure the same access point in another location.

Configuring a Location for an Access Point (GUI)

Before you begin


Note


When you create local and remote sites in the Basic Setup workflow, corresponding policies and tags are created in the backend. These tags and policies that are created in the Basic Setup cannot be modified using the Advanced workflow, and vice versa.


Procedure


Step 1

Choose Configuration > Wireless Setup > Basic.

Step 2

On the Basic Wireless Setup page, click Add.

Step 3

In the General tab, enter a name and description for the location.

Step 4

Set the Location Type as either Local or Flex.

Step 5

Use the slider to set Client Density as Low, Typical or High.

Step 6

Click Apply.


Configuring a Location for an Access Point (CLI)

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ap location name location_name

Example:

Device(config)# ap location name location1

Configures a location for an access point.

Run the no form of this command to remove location for an access point.

Step 3

tag {policy policy_name| rf rf_name | site site_name}

Example:

Device(config-ap-location)# tag policy policy_tag
Device(config-ap-location)# tag rf rf_tag
Device(config-ap-location)# tag site site_tag

Configures tags for the location.

Step 4

location description

Example:

Device(config-ap-location)# location description

Adds description to the location.

Step 5

end

Example:

Device(config-ap-location)# end

Returns to privileged EXEC mode. Alternatively, you can also press Ctrl-Z to exit global configuration mode.

Adding an Access Point to the Location (GUI)


Note


When the tag source is not set to location, the AP count and AP location tagging will not be correctly reflected on the web UI. To change static tag source on the AP, run the no ap ap-mac command on the controller to change AP tag source to default (which is location).


Procedure


Step 1

Choose Configuration > Wireless Setup > Basic.

Step 2

On theBasic Wireless Setup page, click Add to configure the following:

  • General

  • Wireless Networks

  • AP Provisioning

Step 3

In the AP Provisioning tab and Add/Select APs section, enter the AP MAC address and click the right arrow to add the AP to the associated list.

You can also add a CSV file from your system. Ensure that the CSV has the MAC Address column.

Step 4

Use the search option in the Available AP List to select the APs from the Selected AP list and click the right arrow to add the AP to the associated list.

Step 5

Click Apply.


Adding an Access Point to the Location (CLI)
