/caps-man aaa
Settings to configure CAPsMAN AAA functionality are found in /caps-man aaa menu:
| Property | Description |
|---|---|
| mac-format (string; Default: XX:XX:XX:XX:XX:XX) | Controls how MAC address of the client is encoded by Access Point in the User-Name attribute of the MAC authentication and MAC accounting RADIUS requests. |
| mac-mode (as-username | as-username-and-password; Default: as username) | By default Access Point uses an empty password, when sending Access-Request during MAC authentication. When this property is set to as-username-and-password, Access Point will use the same value for User-Password attribute as for the User-Name attribute. |
| mac-caching (disabled | time-interval; Default: disabled) | If this value is set to time interval, the Access Point will cache RADIUS MAC authentication responses for specified time, and will not contact RADIUS server if matching cache entry already exists. Value disabled will disable cache, Access Point will always contact RADIUS server. |
| interim-update (disabled | time-interval; Default: disabled) | When RADIUS accounting is used, Access Point periodically sends accounting information updates to the RADIUS server. This property specifies default update interval that can be overridden by the RADIUS server using the Acct-Interim-Interval attribute. |
| called-format (mac | mac:ssid | ssid; Default: mac:ssid) | Format of how the "called-id" identifier will be passed to RADIUS. When configuring radius server clients, you can specify "called-id" in order to separate multiple entires. |
Example
Assuming that rest of the settings are already configured and only the "Security" part have been left.
Radius authentication with one server
1. Create CAPsMAN security configuration
2. Configure Radius server client
3. Assign the configuration to your master profile (or directly to CAP itself)
/caps-man security add authentication-types=wpa2-eap eap-methods=passthrough encryption=aes-ccm group-encryption=aes-ccm name=radius /radius add address=x.x.x.x secret=SecretUserPass service=wireless /caps-man configuration set security=radius
Radius authentication with different radius servers for each SSID
1. Create CAPsMAN security configuration
2. Configure AAA settings
3. Configure Radius server clients
4. Assign the configuration to your master profile (or directly to CAP itself)
/caps-man security add authentication-types=wpa2-eap eap-methods=passthrough encryption=aes-ccm group-encryption=aes-ccm name=radius /caps-man aaa set called-format=ssid /radius add address=x.x.x.x secret=SecretUserPass service=wireless called-id=SSID1 /radius add address=y.y.y.y secret=SecretUserPass service=wireless called-id=SSID2 /caps-man configuration set security=radius
Now everyone connecting to CAP's with ssid=SSID1 will have their radius authentication requests sent to x.x.x.x and everyone connecting to CAP's with ssid=SSID2 will have their radius authentication requests sent to y.y.y.y
/caps-man access-list
Access list on CAPsMAN is an ordered list of rules that is used to allow/deny clients to connect to any CAP under CAPsMAN control. When client attempts to connect to a CAP that is controlled by CAPsMAN, CAP forwards that request to CAPsMAN. As a part of registration process, CAPsMAN consults access list to determine if client should be allowed to connect. The default behaviour of the access list is to allow connection.
Access list rules are processed one by one until matching rule is found. Then the action in the matching rule is executed. If action specifies that client should be accepted, client is accepted, potentially overriding it's default connection parameters with ones specified in access list rule.
Access list is configured in /caps-man access-list menu. There are the following parameters for access list rules:
- client matching parameters:
- address - MAC address of client
- mask - MAC address mask to apply when comparing client address
- interface - optional interface to compare with interface to which client actually connects to
- time - time of day and days when rule matches
- signal-range - range in which client signal must fit for rule to match
- allow-signal-out-of-range - option which permits client's signal to be out of the range always or for some time interval
- action parameter - specifies action to take when client matches:
- accept - accept client
- reject - reject client
- query-radius - query RADIUS server if particular client is allowed to connect
- connection parameters:
- ap-tx-limit - tx speed limit in direction to client
- client-tx-limit - tx speed limit in direction to AP (applies to RouterOS clients only)
- client-to-client-forwarding - specifies whether to allow forwarding data received from this client to other clients connected to the same interface
- private-passphrase - PSK passphrase to use for this client if some PSK authentication algorithm is used
- radius-accounting - specifies if RADIUS traffic accounting should be used if RADIUS authentication gets done for this client
- vlan-mode - VLAN tagging mode specifies if traffic coming from client should get tagged (and untagged when going to client).
- vlan-id - VLAN ID to use if doing VLAN tagging.

/caps-man datapath
Datapath settings control data forwarding related aspects. On CAPsMAN datapath settings are configured in datapath profile menu /caps-man datapath or directly in a configuration profile or interface menu as settings with datapath. prefix.
There are 2 major forwarding modes:
- local forwarding mode, where CAP is locally forwarding data to and from wireless interface
- manager forwarding mode, where CAP sends to CAPsMAN all data received over wireless and only sends out the wireless data received from CAPsMAN. In this mode even client-to-client forwarding is controlled and performed by CAPsMAN.
Forwarding mode is configured on a per-interface basis - so if one CAP provides 2 radio interfaces, one can be configured to operate in local forwarding mode and the other in manager forwarding mode. The same applies to Virtual-AP interfaces - each can have different forwarding mode from master interface or other Virtual-AP interfaces.
Most of the datapath settings are used only when in manager forwarding mode, because in local forwarding mode CAPsMAN does not have control over data forwarding.
There are the following datapath settings:
- bridge -- bridge interface to add interface to, as a bridge port, when enabled
- bridge-cost -- bridge port cost to use when adding as bridge port
- bridge-horizon -- bridge horizon to use when adding as bridge port
- client-to-client-forwarding -- controls if client-to-client forwarding between wireless clients connected to interface should be allowed, in local forwarding mode this function is performed by CAP, otherwise it is performed by CAPsMAN.
- local-forwarding -- controls forwarding mode
- openflow-switch -- OpenFlow switch to add interface to, as port when enabled
- vlan-id -- VLAN ID to assign to interface if vlan-mode enables use of VLAN tagging
- vlan-mode -- VLAN tagging mode specifies if VLAN tag should be assigned to interface (causes all received data to get tagged with VLAN tag and allows interface to only send out data tagged with given tag)
/caps-man interface
CAPsMAN interfaces are managed in /caps-man interface menu:
[admin@CM] > /caps-man interface print Flags: M - master, D - dynamic, B - bound, X - disabled, I - inactive, R - running # NAME RADIO-MAC MASTER-INTERFACE 0 M BR cap2 00:0C:42:1B:4E:F5 none 1 B cap3 00:00:00:00:00:00 cap2
/caps-man manager
| Property | Description |

| enabled (yes | no; Default: no) | Disable or enable CAPsMAN functionality |
| certificate (auto | certificate name | none; Default: none) | Device certificate |
| ca-certificate (auto | certificate name | none; Default: none) | Device CA certificate |
| require-peer-certificate (yes | no; Default: no) | Require all connecting CAPs to have a valid certificate |
| package-path (string |; Default: ) | Folder location for the RouterOS packages. For example, use "/upgrade" to specify the upgrade folder from the files section. If empty string is set, CAPsMAN can use built-in RouterOS packages, note that in this case only CAPs with the same architecture as CAPsMAN will be upgraded. |
| upgrade-policy (none | require-same-version | suggest-same-upgrade; Default: none) | Upgrade policy options
|
/caps-man provisioning
CAPsMAN distinguishes between CAPs based on a common-name identifier. The identifier is generated based on the following rules:
- if CAP provided a certificate, the identifier is set to the Common Name field in the certificate
- otherwise identifier is based on Base-MAC provided by CAP in the form: '[XX:XX:XX:XX:XX:XX]'.
When the DTLS connection with CAP is successfully established (which means that CAP identifier is known and valid), CAPsMAN makes sure there is no stale connection with CAP using the same identifier. Currently connected CAPs are listed in /caps-man remote-cap menu:
[admin@CM] /caps-man> remote-cap print # ADDRESS IDENT STATE RADIOS 0 00:0C:42:00:C0:32/27044 MT-000C4200C032 Run 1
CAPsMAN distinguishes between actual wireless interfaces (radios) based on their builtin MAC address (radio-mac). This implies that it is impossible to manage two radios with the same MAC address on one CAPsMAN. Radios currently managed by CAPsMAN (provided by connected CAPs) are listed in /caps-man radio menu:
[admin@CM] /caps-man> radio print Flags: L - local, P - provisioned # RADIO-MAC INTERFACE REMOTE-AP-IDENT 0 P 00:03:7F:48:CC:07 cap1 MT-000C4200C032
When CAP connects, CAPsMAN at first tries to bind each CAP radio to CAPsMAN master interface based on radio-mac. If an appropriate interface is found, radio gets set up using master interface configuration and configuration of slave interfaces that refer to particular master interface. At this moment interfaces (both master and slaves) are considered bound to radio and radio is considered provisioned.
If no matching master interface for radio is found, CAPsMAN executes 'provisioning rules'. Provisioning rules is an ordered list of rules that contain settings that specify which radio to match and settings that specify what action to take if a radio matches.
Provisioning rules for matching radios are configured in /caps-man provisioning menu:
| Property | Description |
|---|---|
| action (create-disabled | create-enabled | create-dynamic-enabled | none; Default: none) | Action to take if rule matches are specified by the following settings:
|
| comment (string; Default: ) | Short description of the Provisioning rule |
| common-name-regexp (string; Default: ) | Regular expression to match radios by common name. Each CAP's common name identifier can be found under "/caps-man radio" as value "REMOTE-CAP-NAME" |
| hw-supported-modes (a|a-turbo|ac|an|b|g|g-turbo|gn; Default: ) | Match radios by supported wireless modes |
| identity-regexp (string; Default: ) | Regular expression to match radios by router identity |
| ip-address-ranges (IpAddressRange[,IpAddressRanges] max 100x; Default: "") | Match CAPs with IPs within configured address range. |
| master-configuration (string; Default: ) | If action specifies to create interfaces, then a new master interface with its configuration set to this configuration profile will be created |
| name-format (cap | identity | prefix | prefix-identity; Default: cap) | specify the syntax of the CAP interface name creation
|
| name-prefix (string; Default: ) | name prefix which can be used in the name-format for creating the CAP interface names |
| radio-mac (MAC address; Default: 00:00:00:00:00:00) | MAC address of radio to be matched, empty MAC (00:00:00:00:00:00) means match all MAC addresses |
| slave-configurations (string; Default: ) | If action specifies to create interfaces, then a new slave interface for each configuration profile in this list is created. |
Note: If no rule matches radio, then implicit default rule with action create-enabled and no configurations set is executed.
To get the active provisioning matchers:
[admin@CM] /caps-man provisioning> print
Flags: X - disabled
0 radio-mac=00:00:00:00:00:00 action=create-enabled master-configuration=main-cfg
slave-configurations=virtual-ap-cfg name-prefix=""
For user's convenience there are commands that allow the re-execution of the provisioning process for some radio or all radios provided by some AP:
[admin@CM] > caps-man radio provision 0
and
[admin@CM] > caps-man remote-cap provision 0
