aaa accounting identity

To enable accounting and to create an accounting method list for Session Aware Networking subscriber services, use the aaa accounting identity command in global configuration mode. To disable accounting for Session Aware Networking, use the no form of this command.

aaa accounting identity { method-list-name | default } start-stop [broadcast] group { server-group-name | radius | tacacs+ } [ group { server-group-name | radius | tacacs+ } ]

no aaa accounting identity { method-list-name | default }

Syntax Description

method-list-name

Name of the method list for which to create accounting services by specifying the accounting methods that follow this name.

default

Creates a default method list for accounting services using the accounting methods that follow this keyword.

start-stop

Sends a “start” accounting notice at the beginning of a process and a “stop” accounting notice at the end of a process. The “start” accounting record is sent in the background. The requested user process begins regardless of whether the “start” accounting notice was received by the accounting server.

broadcast

(Optional) Sends accounting records to multiple authentication, authorization, and accounting (AAA) servers. Simultaneously sends accounting records to the first server in each group. If the first server is unavailable, the device uses the backup servers defined within that group.

group

Specifies one or more server groups to use for accounting services. Server groups are applied in the specified order.

server-group-name

Named subset of RADIUS or TACACS+ servers as defined by the aaa group server radius command or aaa group server tacacs+ command.

radius

Uses the list of all RADIUS servers configured with the radius-server host command.

tacacs+

Uses the list of all TACACS+ servers configured with the tacacs-server host command.

Command Default

Accounting is disabled.

Command Modes

Global configuration (config)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The aaa accounting identity command enables accounting services and creates method lists that define specific accounting methods for Session Aware Networking subscriber services. A method list identifies the list of security servers to which the network access server sends accounting records.

Cisco IOS software supports the following two methods of accounting for Session Aware Networking:

  • RADIUS—The network access server reports user activity to the RADIUS security server in the form of accounting records. Each accounting record contains accounting attribute-value (AV) pairs and is stored on the security server.
  • TACACS+—The network access server reports user activity to the TACACS+ security server in the form of accounting records. Each accounting record contains accounting AV pairs and is stored on the security server.

The default method list is automatically applied to all subscriber sessions except those that have a named method list explicitly defined. A named method list overrides the default method list.

When AAA accounting is activated, the network access server monitors either RADIUS accounting attributes or TACACS+ AV pairs pertinent to the connection, depending on the security method you have implemented. The network access server reports these attributes as accounting records, which are then stored in an accounting log on the security server.

You must enable AAA with the aaa new-model command before you can enter the aaa accounting identity command.

Examples

The following example shows how to configure a default accounting method list where accounting services are provided by a TACACS+ server.

aaa new-model
aaa accounting identity default start-stop group tacacs+

The following example shows how to configure a named accounting method list, where accounting services are provided by a RADIUS server.

aaa new model
aaa accounting identity LIST_1 start-stop group radius

Command History

Release Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The access-session closed command closes access to a port, preventing clients or devices from gaining network access before authentication is performed.

Examples

The following example shows how to set port 1/0/2 to closed access.

interface GigabitEthernet 1/0/2
 access-session host-mode single-host
 access-session closed
 access-session port-control auto
 access-session control-direction in

Related Commands

access-session control-direction

Sets the direction of authentication control on a port.

access-session host-mode

Allows hosts to gain access to a controlled port.

access-session port-control

Sets the authorization state of a port.

access-session control-direction

To set the direction of authentication control on a port, use the access-session control-direction command in interface configuration mode. To return to the default value, use the no form of this command.

access-session control-direction { both | in }

no access-session control-direction

Syntax Description

both

Enables bidirectional control on the port. This is the default value.

in

Enables unidirectional control on the port.

Command Default

The port is set to bidirectional mode.

Command Modes

Interface configuration (config-if)

Command History

Release Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the access-session control-direction command to set the port control to either unidirectional or bidirectional.

The in keyword configures a port as unidirectional, allowing a device on the network to “wake up” the client and force it to reauthenticate. The port can send packets to the host but cannot receive packets from the host.

The both keyword configures a port as bidirectional so that access to the port is controlled in both directions. The port cannot send or receive packets.

You can use the show access-session interface command to verify the port setting.

Examples

The following example shows how to enable unidirectional control on port 1/0/2:

interface GigabitEthernet 1/0/2
 access-session host-mode single-host
 access-session closed
 access-session port-control auto
 access-session control-direction in

Related Commands

access-session closed

Prevents preauthentication access on a port.

access-session host-mode

access-session host-mode

To allow hosts to gain access to a controlled port, use the access-session host-mode command in interface configuration mode. To return to the default value, use the no form of this command.

access-session host-mode { multi-auth | multi-domain | multi-host | single-host }

no access-session host-mode

Syntax Description

multi-auth

Specifies that multiple clients can be authenticated on the port at any given time. This is the default value.

multi-domain

Specifies that only one client per domain (DATA or VOICE) can be authenticated at a time.

multi-host

Specifies that after the first client is authenticated all subsequent clients are allowed access.

single-host

Specifies that only one client can be authenticated on a port at any given time. A security violation occurs if more than one client is detected.

Command Default

Access to a port is multi-auth.

Command Modes

Interface configuration (config-if)

Command History

Release Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Before you use this command, you must enable the access-session port-control auto command.

In multi-host mode, only one of the attached hosts has to be successfully authorized for all hosts to be granted network access. If the port becomes unauthorized (reauthentication fails or an Extensible Authentication Protocol over LAN (EAPOL) logoff message is received), all attached clients are denied access to the network.

You can use the show access-session interface command to verify the port setting.

Examples

The following example shows how to authenticate a single client at a time on port 1/0/2:

interface GigabitEthernet 1/0/2
 access-session host-mode single-host
 access-session closed
 access-session port-control auto
 access-session control-direction in

Related Commands

access-session port-control { auto | force-authorized | force-unauthorized }

no access-session port-control

Syntax Description

auto

Enables port-based authentication and causes the port to begin in the unauthorized state, allowing only Extensible Authentication Protocol over LAN (EAPOL) frames to be sent and received through the port.

force-authorized

Disables IEEE 802.1X on the interface and causes the port to change to the authorized state without requiring any authentication exchange. The port transmits and receives normal traffic without 802.1X-based authentication of the client. This is the default value.

force-unauthorized

Denies all access through this interface by forcing the port to change to the unauthorized state, ignoring all attempts by the client to authenticate.

Command Default

The port is set to the force-authorized state.

Command Modes

Interface configuration (config-if)

Command History

Release Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The authentication process begins when the link state of the port transitions from down to up or when an EAPOL-start frame is received. The system requests the identity of the client and begins relaying authentication messages between the client and the authentication server.

Examples

The following example shows how to set the authorization state on port 1/0/2 to automatic:

interface GigabitEthernet 1/0/2
 access-session host-mode single-host
 access-session closed
 access-session port-control auto
 access-session control-direction in

15.2(1)E

This command was integrated into Cisco IOS Release 15.2(1)E.

Usage Guidelines

The activate command defines an action in a control policy.

Control policies determine the actions taken in response to specified events and conditions. The control class defines the conditions that must be met before actions are executed. Actions are numbered and executed sequentially within a policy rule.

The class command creates a policy rule by associating a control class with one or more actions.

Examples

The following example shows how to configure a control policy named SEQ-AUTH-WITH-AUTH-FAIL-VLAN. If authentication fails, and all conditions in the control class DOT1X_FAILED evaluate true, the system activates the service template named VLAN4.

class-map type control subscriber DOT1X-FAILED match-any
  match result-type method dot1x authoritative
  match result-type method dot1x agent-not-found
!
class-map type control subscriber MAB-FAILED match-all

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The authenticate using command defines an action in a control policy.

Control policies determine the actions taken in response to specified events and conditions. The control class defines the conditions that must be met before the actions are executed. The actions are numbered and executed sequentially within the policy rule.

The class command creates a policy rule by associating a control class with one or more actions.

When an AAA method list is configured, the RADIUS or TACACS+ AAA server checks for a valid account by looking at the username and password. The authentication list and the authorization list usually share the same AAA method list; the lists can use different databases but it is not recommended.

Examples

The following example shows the partial configuration of a control policy named CONC_AUTH. When a session starts, the default control class specifies that 802.1X and MAB authentication run concurrently. 802.1X has a higher priority (10) than MAB (20) so 802.1X is used to authenticate the session, unless it fails, and then MAB authentication is used.

policy-map type control subscriber CONC_AUTH
 event session-started match-all
  10 class always do-until-failure
   10 authenticate using dot1x priority 10
   20 authenticate using mab priority 20

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

15.2(1)E

This command was integrated into Cisco IOS Release 15.2(1)E.

Usage Guidelines

The class command associates the conditions in a control class with one or more actions in a control policy. A control class defines the conditions that must be met before a set of actions are executed. The association of a control class and a set of actions is called a control policy rule.

Use the control-class-name argument to specify a named control class that was created using the class-map type control subscriber command.

Use the always keyword to create a default control class that always evaluates true for the given event.

Examples

The following example shows how to configure a control class named DOT1X-NO-AGENT. The class command associates DOT1X-NO-AGENT with the control policy named POLICY-1. If DOT1X-NO-AGENT evaluates true, the actions associated with the class are executed.

class-map type control subscriber match-first DOT1X-NO-AGENT
 match result-type method dot1x agent-not-found
!
policy-map type control subscriber POLICY-1
 event session-started match-all
  10 class always do-all
   10 authenticate using dot1x priority 10

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

15.2(1)E

This command was integrated into Cisco IOS Release 15.2(1)E.

Usage Guidelines

A control class defines the conditions that must be met for the actions in a control policy to be executed. A control class can contain multiple conditions. Use the match-any, match-all, or match-none keywords to specify which, if any, of the conditions the subscriber session must match for the actions to be executed.

A control policy, which is configured with the policy-map type control subscriber command, contains one or more control classes that are evaluated based on the event specified with the event command. Use the class command to create a policy rule by associating a control class with one or more actions.

Examples

The following example shows the partial configuration for a control class named DOT1X-AUTHORITATIVE, which is associated with the control policy named DOT1X-MAB-WEBAUTH. If an authentication-failure event occurs, and the session matches all of the conditions in DOT1X-AUTHORITATIVE, the policy executes the authenticate action and attempts to authenticate the session using MAC authentication bypass (MAB).

class-map type control subscriber match-all DOT1X-AUTHORITATIVE
  match method dot1x
  match result-type authoritative

consent email

To request a user’s e-mail address on the consent login web page, use the consent email command in parameter map webauth configuration mode. To remove the consent parameter file from the map, use the no form of this command.

consent email

no consent email

Syntax Description

This command has no arguments or keywords.

Command Default

The e-mail address is not requested on the consent login page.

Command Modes

Parameter map webauth configuration (config-params-parameter-map)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the consent email command to display a text box on the consent login page prompting the user to enter his or her e-mail address for identification. The device sends this e-mail address to the authentication, authorization, and accounting (AAA) server instead of sending the client’s MAC address.

The consent feature allows you to provide temporary Internet and corporate access to end users through their wired and wireless networks by presenting a consent web page. This web page lists the terms and conditions under which the organization is willing to grant access to end users. Users can connect to the network only after they accept the terms on the consent web page.

If you create a parameter map with the type command set to consent, the device does not prompt the user for his or her username and password credentials. Users instead get a choice of two radio buttons: accept or do not accept. For accounting purposes, the device sends the client’s MAC address to the AAA server if no username is available (because consent is enabled).

This command is supported in named parameter maps only.

Examples

The following example shows how to enable the consent e-mail feature in a parameter map:

parameter-map type webauth PMAP_1
 type consent
 consent email
 banner file flash:consent_page.htm

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the custom-page command to display custom web pages during web authentication login. To enable custom web pages:
  • You must specify all four custom HTML files. If fewer than four files are specified, the internal default HTML pages are used.
  • The four custom HTML files and any images in the custom pages must be stored in the disk or flash of the switch. The maximum size of each HTML file is 256 KB.
  • Filenames must start with web_auth.
  • To serve custom pages and images from an external server, you must configure a redirect portal IP address by using the redirect (parameter-map webauth) command instead of using local custom pages.
  • Any external link from a custom page requires an intercept ACL configuration.
  • Any name resolution required for external links or images requires an intercept ACL configuration.
  • If the custom web pages feature is enabled, the redirection URL for successful login feature will not be available.
  • Because the custom login page is a public web form, consider the following guidelines for this page:
    • The login form must accept user input for the username and password and must POST the data as uname and pwd.
    • The custom login page should follow best practices for a web form, such as page timeout, hidden password, and prevention of redundant submissions.

Examples

The following example shows how to configure a named parameter map for web authentication with custom pages enabled:

parameter-map type webauth PMAP_WEBAUTH
 type webauth
 custom-page login device flash:webauth_login.html
 custom-page success device flash:webauth_success.html
 custom-page failure device flash:webauth_fail.html

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The err-disable command defines an action in a control policy.

Control policies determine the actions taken in response to specified events and conditions. The control class defines the conditions that must be met before the policy can execute the actions. The actions are numbered and executed sequentially within the policy rule.

The class command creates a policy rule by associating a control class with one or more actions. The actions that you can define in a policy rule depend on the type of event that you specify with the event command.

After the policy executes this action, the port remains disabled until the interval set with the error recovery interval command expires (default is 300 seconds). If you have not enabled error recovery with the errdisable recovery cause security-violation command, the port remains disabled indefinitely.

Examples

The following example shows how to configure a control policy with the err-disable action configured:

  • authentication-failure—Session authentication has failed.
  • authentication-success—Session is successfully authenticated.
  • authorization-failure—Port authorization has failed.
  • inactivity-timeout—Inactivity timer has expired for the session. This timer is configured with the inactivity-timer command.
  • remote-authentication-failure—Remote session authentication failed.
  • remote-authentication-success—Remote session successfully authenticated.
 
  • session-started—Port-up event resulted in creating a session. This event is triggered when a new MAC address is detected on the relevant interface.
  • tag-added—A service template tag was added. This tag is specified with the tag (service-template) command.
  • tag-removed—A service template tag was removed.
  • template-activated—A service template is activated on the session.
  • template-activation-failed—Activating a service template on the session failed.
  • template-deactivated—A service template is deactivated on the session.

Cisco IOS XE Release 3.3SE

This command was modified. The remote-authentication-failure and remote-authentication-success keywords were added.

Usage Guidelines

The event command configures an event condition in a control policy. After the specified event occurs, the system evaluates the control classes. Control classes specify the conditions that must be met to execute the actions in the control policy. The class command creates a policy rule by associating a control class with one or more actions.

The event command determines the actions that can be defined in a policy rule. For example, the action defined with the err-disable command can only be configured for a violation event.

The table below lists the events that have default actions.

Table 1 Events with Default Actions

Event

Default Action

authentication-failure

Session manager checks for a violation and unauthorizes the session if no other method is still running, unless the control policy explicitly specifies authorization.

authentication-success

Session manager authorizes the session, unless the control policy explicitly specifies unauthorization.

authorization-failure

Session manager unauthorizes the session, unless the control policy explicitly specifies authorization.

violation

Session manager generates a restrict violation on the port, unless the control policy explicitly specifies a different action.


Note


The remote-authentication-failure and remote-authentication-success keywords are generated when web authentication success or failure occurs at the Guest Controller (GC) when a user configures CGA and provisions web authentication at the GC. This information is propagated from GC to the access switch.

Examples

The following example shows how to configure a control policy named POLICY-3. This control policy has two events associated with it; one for session creation and the other for authentication failures. The authentication-failure event has two control classes associated with it.

class-map type control subscriber match-all MAB-FAILED
 match method mab

Command Default

Disabled (the inactivity timeout is 0).

Command Modes

Service template configuration (config-service-template)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the inactivity-timer command to set the maximum amount of time that a subscriber session can exist with no activity or data from the end client. If this timer expires before there is any activity or data, the session is cleared.

The probe keyword enables ARP probes. The IP device tracking table maintains a list of known host devices and periodically probes those devices to verify that they are still active. If all probes go unanswered, the session is cleared. Because the host is removed from the IP device tracking table after the inactivity timeout, no further probes are sent, and the inactive end host must send ARP traffic to reinitiate the session.

To set the number and time interval of ARP probes, use the ip device tracking probe command.

Examples

The following example shows how to configure a service template with the activity timer set to 15 minutes:

service-template SVC_2
 description label for SVC_2
 access-group ACL_2
 redirect url http://www.cisco.com
 inactivity-timer 15

A control class can contain multiple conditions, each of which will evaluate as either true or false. The control class defines whether all, any, or none of the conditions must evaluate true to execute the actions of the control policy.

The no-match form of this command specifies a value that results in an unsuccessful match. All other values of the specified match criterion result in a successful match. For example, if you configure the no-match result-type method dot1x method-timeout command, the control class accepts any result value except dot1x method-timeout as a successful match.

The class command associates a control class with a control policy.

Examples

The following example shows how to configure a control class named ALL-FAILED that includes no-match conditions based on the authentication result:

class-map type subscriber control match-all ALL-FAILED
 no-match result-type method dot1x none
 no-match result-type method dot1x success
 no-match result-type method mab none
 no-match result-type method mab success
 no-match result-type method webauth none
 no-match result-type method webauth success

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the parameter-map type webauth command to define a parameter map for web authentication. A parameter map allows you to specify parameters that control the behavior of actions configured under a policy map with the authenticate using webauth command.

A global parameter map contains system-wide parameters. This parameter map is not attached to the web authentication action and has parameters for both web authentication and consent. The global parameter map is automatically applied to the authentication action. If you explicitly apply a named parameter map, and there are parameters that are common to both the global and named parameter map, the global parameter map configuration takes precedence.

The configuration parameters supported for a global parameter map defined with the global keyword are different from the parameters supported for a named parameter map defined with the parameter-map-name argument.

Examples

The following example shows how to configure a parameter map named PMAP_2, which is used by the control policy named POLICY_1 to authenticate users:

parameter-map type webauth PMAP_2
 type webconsent
 max-login-attempts 5
 banner file flash:consent_page.htm

15.2(1)E

This command was integrated into Cisco IOS Release 15.2(1)E.

Usage Guidelines

Control policies define the actions taken in response to specified events and conditions.

A control policy consists of one or more control policy rules. A control policy rule associates a control class with one or more actions. The control class defines the conditions that must be met before the actions are executed. Actions are numbered and executed sequentially.

There are three steps in defining a control policy:

  1. Create one or more control classes by using the class-map type control subscriber command.
  2. Create a control policy by using the policy-map type control subscriber command.
  3. Apply the control policy to a context by using the service-policy type control subscriber command.

Examples

The following example shows how to configure a control policy named DOT1X-MAB-WEBAUTH. If an authentication-failure event occurs, and the session matches all conditions in the control class named DOT1X-AUTHORITATIVE, the policy executes the authenticate action and attempts to authenticate the session using MAC authentication bypass (MAB).

class-map type control subscriber match-all DOT1X-AUTHORITATIVE

Usage Guidelines

You can use multiple radius-server host commands to specify multiple hosts. The software searches for hosts in the order in which you specify them.

If no host-specific timeout, retransmit, or key values are specified, the global values apply to each host.

We recommend the use of a test user who is not defined on the RADIUS server for the automated testing of the RADIUS server. This is to protect against security issues that can arise if the test user is not configured correctly.

If you configure one RADIUS server with a nonstandard option and another RADIUS server without the nonstandard option, the RADIUS server host with the nonstandard option does not accept a predefined host. However, if you configure the same RADIUS server host IP address for different UDP destination ports, where one UDP destination port (for accounting requests) is configured using the acct-port keyword and another UDP destination port (for authentication requests) is configured using the auth-port keyword with and without the nonstandard option, the RADIUS server does not accept the nonstandard option. This results in resetting all the port numbers. You must specify a host and configure accounting and authentication ports on a single line.

To use separate servers for accounting and authentication, use the zero port value as appropriate.

RADIUS Server Automated Testing

When you use the radius-server host command to enable automated testing for RADIUS server load balancing:

  • The authentication port is enabled by default. If the port number is not specified, the default port number (1645) is used. To disable the authentication port, specify the ignore-auth-port keyword.
  • The accounting port is enabled by default. If the port number is not specified, the default port number (1645) is used. To disable the accounting port, specify the ignore-acct-port keyword.

Examples

The following example shows how to specify host1 as the RADIUS server and to use default ports for both accounting and authentication depending on the Cisco release that you are using:

radius-server host host1

The following example shows how to specify port 1612 as the destination port for authentication requests and port 1616 as the destination port for accounting requests on the RADIUS host named host1:

radius-server host host1 auth-port 1612 acct-port 1616

Because entering a line resets all the port numbers, you must specify a host and configure accounting and authentication ports on a single line.

The following example shows how to specify the host with IP address 192.0.2.46 as the RADIUS server, uses ports 1612 and 1616 as the authorization and accounting ports, sets the timeout value to six, sets the retransmit value to five, and sets “rad123” as the encryption key, thereby matching the key on the RADIUS server:

radius-server host 192.0.2.46 auth-port 1612 acct-port 1616 timeout 6 retransmit 5 key rad123

To use separate servers for accounting and authentication, use the zero port value as appropriate.

The following example shows how to specify the RADIUS server host1 for accounting but not for authentication, and the RADIUS server host2 for authentication but not for accounting:

radius-server host host1.example.com auth-port 0
radius-server host host2.example.com acct-port 0

The following example shows how to specify four aliases on the RADIUS server with IP address 192.0.2.1:

radius-server host 192.0.2.1 auth-port 1646 acct-port 1645
radius-server host 192.0.2.1 alias 192.0.2.2 192.0.2.3 192.0.2.4

The following example shows how to enable exponential backoff retransmits on a per-server basis. In this example, assume that the retransmit is configured for three retries and the timeout is configured for five seconds; that is, the RADIUS request will be transmitted three times with a delay of five seconds. Thereafter, the device will continue to retransmit RADIUS requests with a delayed interval that doubles each time until 32 retries have been achieved. The device will stop doubling the retransmit intervals after the interval surpasses the configured 60 minutes; it will transmit every 60 minutes.

The pac keyword allows the PAC-Opaque, which is a variable length field, to be sent to the server during the Transport Layer Security (TLS) tunnel establishment phase. The PAC-Opaque can be interpreted only by the server to recover the required information for the server to validate the peer’s identity and authentication. For example, the PAC-Opaque may include the PAC-Key and the PAC’s peer identity. The PAC-Opaque format and contents are specific to the issuing PAC server.

The following example shows how to configure automatic PAC provisioning on a device. In seed devices, the PAC-Opaque has to be provisioned so that all RADIUS exchanges can use this PAC-Opaque to enable automatic PAC provisioning for the server being used. All nonseed devices obtain the PAC-Opaque during the authentication phase of a link initialization.

Sends users to this URL for login.

on-failure

Sends users to this URL if the login fails.

on-success

Sends users to this URL if the login is successful.

url

Valid URL.

portal

Sends users to this external web server to access the customized login web pages.

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the redirect command to redirect users to custom web pages stored on an external server during the authentication process.

The device redirects the client to the specified portal IP address after it intercepts the initial HTTP request. The device also intercepts the login form sent by the client so it can extract the username and password and authenticates the user.

To display custom web pages that are stored locally, use the custom-page command.

When you configure the redirect portal command, web authentication creates intercept ACLs that include an entry to deny (not intercept) the redirect portal address. For example, if you configure the command redirect portal ipv4 10.51.3.34, the show ipv4 access-list command would display the following output:

Extended IP access list WA-v4-int-acl-pmap-PA
    10 deny tcp any host 10.51.3.34 eq www
    20 deny tcp any host 10.51.3.34 eq 443
    30 permit tcp any any eq www
    40 permit tcp any any eq 443

Examples

The following example shows how to configure a named parameter map that redirects users to custom web pages:

parameter-map type webauth PMAP_WEBAUTH
 type webauth
 redirect for-login http://10.10.3.34/~sample/login.html
 redirect on-success http://10.10.3.34/~sample/success.html
 redirect on-failure http://10.10.3.34/~sample/failure.html

Table 2 show access-session Field Descriptions

Field

Description

Interface

The type and number of the authentication interface.

MAC Address

The MAC address of the client.

Domain

The name of the domain, either DATA or VOICE.

Status

The status of the authentication session. The possible values are:

  • Authc Failed—An authentication method has run for this session and authentication failed.
  • Authc Success—An authentication method has run for this session and authentication was successful.
  • Authz Failed—A feature has failed and the session has terminated.
  • Authz Success—All features have been applied to the session and the session is active.
  • Idle—This session has been initialized but no authentication methods have run. This is an intermediate state.
  • No methods—No authentication method has provided a result for this session.
  • Running—An authentication method is running for this session.

Fg

These status flags indicate that events are temporarily blocked from being processed on a session, usually because an asynchronous action is in progress. A transient block, from less than a second to a few seconds maximum, is to be expected; a session that remains blocked for more than a few seconds indicates an issue.

All flags are mutually exclusive except P which can display with any other flag.

Key to Session Events Blocked Status Flags:

  • A - Applying Policy (multi-line status for details)—A policy action (event) is being carried out and involves asynchronous processing which is in progress. Use the details keyword to see the name of the event being processed.
  • D - Awaiting Deletion—Session deletion has begun. One or more asynchronous actions are currently in progress (either retrieving accounting data from the platform or deleting the IIF ID).
  • F - Final Removal in progress—The D stage is over but the session has not been deleted yet.
  • I - Awaiting IIF ID allocation—The IIF ID is a system-wide identifier for a session or any other object the platform must know about. The platform must have the IIF ID before proceeding.
  • P - Pushed Session—Indicates the session was authenticated earlier and pushed from the wireless controller module (WCM). Session manager only tracks the session rather than performing authentication. This is for wireless sessions only. It is a permanent flag on sessions and can display with other flags.
  • R - Removing User Profile (multi-line status for details)—User profile is being removed asynchronously by the enforcement policy module (EPM).
  • U - Applying User Profile (multi-line status for details)—User profile is being applied asynchronously by the EPM.
  • X - Unknown Blocker—Event is blocked for an unknown reason.

Handle

The context handle.

State

The operating states for the reported authentication sessions. The possible values are:

  • Not run—The method has not run for this session.
  • Running—The method is running for this session.
  • Failed over—The method has failed and the next method is expected to provide a result.
  • Success—The method has provided a successful authentication result for the session.
  • Authc Failed—The method has provided a failed authentication result for the session.

Number of the action. Actions are executed sequentially within the policy rule.

dot1x

Specifies the IEEE 802.1X authentication method.

mab

Specifies the MAC authentication bypass (MAB) method.

webauth

Specifies the web authentication method.

Command Default

An authentication method is not terminated.

Command Modes

Control policy-map action configuration (config-action-control-policymap)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The terminate command defines an action in a control policy.

Control policies determine the actions taken in response to specified events and conditions. The control class defines the conditions that must be met before the actions are executed. The actions are numbered and executed sequentially within the policy rule.

The class command creates a policy rule by associating a control class with one or more actions.

When configuring a control policy, you must explicitly terminate one authentication method before initiating another method. Session aware networking does not automatically terminate one method before attempting the next method. For concurrent authentication, this means you must configure a policy rule that explicitly terminates one method after another method of a higher priority succeeds.

Examples

The following example shows how to configure a control policy that includes the terminate action:

policy-map type control subscriber POLICY_3
 event session-start
  10 class always
   10 authenticate using dot1x
 event agent-not-found
  10 class DOT1X
   10 terminate dot1x
   20 authenticate using mab
 event authentication-success
  10 class DOT1X
   10 terminate mab
   20 terminate web-auth
  20 class MAB
   10 terminate web-auth

Related Commands

timeout init-state min

To set the initialize (Init) state timeout for web authentication sessions, use the timeout init-state min command in parameter-map type webauth configuration mode. To reset the timeout to the default value, use the no form of this command.

timeout init-state min minutes

no timeout init-state min minutes

Syntax Description

minutes

Maximum duration of Init state, in minutes. Range: 1 to 65535. Default: 2.

Command Default

The Init state timeout is two minutes.

Command Modes

Parameter-map type webauth configuration (config-params-parameter-map)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the timeout init-state min command to limit the number of minutes that a web authentication session can stay in the Init state. A session remains in the Init state until the user enters his or her username and password credentials. If the timer expires before the user enters his or her credentials, the session is cleared.

Examples

The following example shows how to set the Init timeout to 15 minutes in the parameter map named MAP_2:

parameter-map type webauth MAP_2
 type webauth
 timeout absolute min 30
 timeout init-state min 15
 max-login-attempts 5

Specifies authentication bypass. Allows access using nonresponsive host (NRH) authentication.

consent

Specifies consent only. Allows default access without prompting users for their username and password credentials. Users instead get a choice of two radio buttons: accept or do not accept. For accounting purposes, the device passes the client’s MAC address to the authentication, authorization, and accounting (AAA) server.

webauth

Specifies web authentication only. Allows access based on the user's privileges. The device sends the username and password to the AAA server for authentication and accounting. This is the default value.

webconsent

Specifies both web authentication and consent.

Command Default

The type is web authentication (webauth).

Command Modes

Parameter-map webauth configuration (config-params-parameter-map)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the type command to specify the authentication method to which the parameters in the map apply. A parameter map defines parameters that control the behavior of actions specified under a policy map.

This command is supported in named parameter maps only.

Examples

The following example shows how to configure a parameter map with the type set to the default of webauth:

parameter-map type webauth PMAP_3
 type webauth
 timeout init-state min 15
 banner file flash:webauth_banner.html

unauthorize

To unauthorize a port and remove any access granted on the basis of previous authorization data, use the unauthorize command in control policy-map action configuration mode. To remove this action from the control policy, use the no form of this command.

action-number unauthorize

no action-number

Syntax Description

action-number

Number of the action. Actions are executed sequentially within the policy rule.

Command Default

Authorization data is not removed.

Command Modes

Control policy-map action configuration (config-action-control-policymap)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

The unauthorize command defines an action in a control policy. This command removes any access that was granted based on previous authorization data, including the user profile and any activated service templates.

Control policies determine the actions taken in response to specified events and conditions. The control class defines the conditions that must be met before the actions will be executed. The actions are numbered and executed sequentially within the policy rule.

The class command creates a policy rule by associating a control class with one or more actions.

Examples

The following example shows how to configure a control policy with the unauthorize action configured for the inactivity-timeout event:

policy-map type control subscriber POLICY
 event inactivity-timeout match-all
  10 class always
   10 unauthorize 

Related Commands

Command

Description

authorize

Initiates the authorization of a subscriber session.

class

policy-map type control subscriber

Defines a control policy for subscriber sessions.

virtual-ip

To specify a virtual IP address for web authentication clients, use the virtual-ip command in parameter-map webauth configuration mode. To remove the address, use the no form of this command.

virtual-ip { ipv4 ipv4-address | ipv6 ipv6-address }

no virtual-ip { ipv4 | ipv6 }

Syntax Description

ipv4 ipv4-address

Specifies the IPv4 address to use as the virtual IP address.

ipv6 ipv6-address

Specifies the IPv6 address to use as the virtual IP address.

Command Default

A virtual IP address is not configured.

Command Modes

Parameter-map webauth configuration (config-params-parameter-map)

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the virtual-ip command to specify the virtual IP address to use for web authentication clients.

If you use default or local custom pages, configuring a virtual IP address will cause a logout web page to be presented to clients after they have been successfully authenticated. This allows users to logout by clicking a link in the logout page. The logout request is sent to the virtual IP address, and is intercepted by the device (an ACL is automatically created so that the logout request is intercepted).

To serve custom pages or other files from an external server, you must configure a virtual IP address. When a user enters his or her credentials in the login form, that form is sent to the virtual IP address and is intercepted by the device so that the client can be authenticated.

The virtual IP address must not be an address on the network or an address on the device.

This command is supported in the global parameter map only.

Examples

The following example shows how to set the virtual IP address to FE80::1 in the global parameter map for web authentication:

parameter-map type webauth global
 timeout init-state min 15
 watch-list enabled
 virtual-ip ipv6 FE80::1

Adds an IP address to the watch list.

ipv4 ipv4-address

Specifies the IPv4 address of a client to add to the watch list.

ipv6 ipv6-address

Specifies the IPv6 address of a client to add to the watch list.

dynamic-expiry-timeout minutes

Sets the duration of time, in minutes, that an entry remains in the watch list. Range: 0 to 2147483647. Default: 30. 0 (zero) keeps the entry in the list permanently.

enabled

Command History

Release

Modification

Cisco IOS XE Release 3.2SE

This command was introduced.

Usage Guidelines

Use the watch-list command to monitor the connections of specific web authentication clients. When you enable the watch list, web authentication dynamically adds clients to the watch list after either of the following events occurs:

  • The client exceeds the maximum number of login attempts allowed, as configured with the ip admission max-login-attempts command.
  • The client exceeds the maximum number of open TCP sessions allowed, as configured with the max-http-conns command (default is 30).

After an IP address is added to the watch list, no new connections are accepted from this IP address (to port 80) until the timer that you set with the dynamic-expiry-timeout keyword expires.

You can manually add an IP address to the watch list by using the add-item keyword.

When you disable a watch list, no new entries are added to the watch list and the sessions are put in the SERVICE_DENIED state.

This command is supported in the global parameter map only.

Examples

The following example shows how to configure the global parameter map with the watch list set to enabled and the timeout set to 20 minutes:

parameter-map type webauth global
 watch-list enabled
 watch-list dynamic-expiry-timeout 20

Note


Entries that you add to the watch list using the add-item keyword do not display in the running configuration. To view these entries, use the show ip admission watch-list command.
