    Introduction

    This document describes how to configure and troubleshoot downloadable ACLs (dACLs) on Catalyst 9800 Wireless LAN Controller (WLC).

     

    Background Information

    dACLs have been supported for many years in Cisco IOS® and IOS XE® switches. A dACL refers to the fact that the network device dynamically downloads the ACL entries from the RADIUS server when authentication occurs, rather than having a local copy of the ACL and just being assigned the ACL name. A more complete Cisco ISE configuration example is available. This document focuses on the Cisco Catalyst 9800 which supports dACLs for central switching since the 17.10 release.

    Prerequisites

    The idea behind this document is to demonstrate dACLs usage on Catalyst 9800 through a basic SSID configuration example, showing how these can be fully customizable.

    On Catalyst 9800 wireless controller, downloadable ACLs are

    • Supported starting from Cisco IOS XE Dublin 17.10.1 release.

    • Supported for centralized controller with Local mode Access Points only (or Flexconnect central switching). FlexConnect Local Switching does not support dACL.

    Requirements

    Cisco recommends that you have knowledge of these topics:

    • Catalyst Wireless 9800 configuration model. 
    • Cisco IP Access Control Lists (ACLs).

    Components Used

    The information in this document is based on these software and hardware versions:

    • Catalyst 9800-CL (v. Dublin 17.12.03).
    • ISE (v. 3.2).

    The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

    Configure

    Throughout this configuration guide, even if methods are different (for example WLAN authentication, policy configuration, and so on), the end result is the same. In the scenario exposed here, two user identities are defined being USER1 and USER2. Both are granted access to the wireless network. To each of them is assigned, respectively, ACL_USER1 and ACL_USER2 being dACLs downloaded by the Catalyst 9800 from ISE.

    WLC Configuration

    For details about 802.1x SSIDs configuration and troubleshooting on the Catalyst 9800, please refer to the Configure 802.1X Authentication on Catalyst 9800 Wireless Controller Series configuration guide.

    Step 1. Configure the SSID.

    Configure a 802.1x authenticated SSID, using ISE as RADIUS server. In this document, the SSID has been named "DACL_DOT1X_SSID".

    From the GUI:

    Navigate to Configuration > Tags & Profiles > WLAN and create a WLAN similar to the one showed here:

    WLC_SSID

    From the CLI:

    WLC#configure terminal
WLC(config)#wlan DACL_DOT1X_SSID 2 DACL_DOT1X_SSID
WLC(config-wlan)#security dot1x authentication-list DOT1X
WLC(config-wlan)#no shutdown

    Step 2. Configure the policy profile.

    Configure the policy profile that is used along with the SSID defined above. On this policy profile, make sure AAA Override is configured from the "Advanced" tab, as showed in the screenshot. In this document, the policy profile used is "DACL-8021X".

    As stated in the prerequisites section, dACLs are only supported for central switching/authentication deployments. Make sure the policy profile is configured that way. 

    From the GUI:

    Navigate to Configuration > Tags & Profiles > Policy, select the policy profile used and configure it as showed.

    WLC_DOT1X_PP_dACL_1

    WLC_DOT1X_PP_dACL_2

    From the CLI:

    WLC#configure terminal
WLC(config)#wireless profile policy DACL-8021X
WLC(config-wireless-policy)#aaa-override
WLC(config-wireless-policy)#vlan VLAN_1413
WLC(config-wireless-policy)#no shutdown

    Step 3. Assign the policy profile and SSID to the policy tag used.

    From the GUI:

    Navigate to Configuration > Tags & Profiles > Tags. From the Policy tags tab, create (or select) the tag used and assign to it the WLAN and policy profile defined during steps 1-2.

    Configure policy tags on the WLC

    From the CLI:

    WLC#configure terminal
WLC(config)#wireless tag policy default-policy-tag
WLC(config-policy-tag)#description "default policy-tag"
WLC(config-policy-tag)#wlan DACL_DOT1X_SSID policy DACL-8021X

    Step 4. Allow Vendor Specific Attribute.

    Downloadable ACLs are passed via vendor specific attributes (VSA) in the RADIUS exchange between ISE and the WLC. The support of these attributes can be enabled on the WLC, using these CLI command.

    From the CLI:

    WLC#configure terminal
WLC(config)#radius-server vsa send authentication

    Step 5. Configure Default Authorization List.

    When working with dACL, network authorization through RADIUS must be enforced for the WLC to authorize any user authenticating to the 802.1x SSID configured. Indeed, not only the authentication but the authorization phase is handled on the RADIUS server side here. Therefore, the authorization list is required in this case.

    Make sure the default network authorization method is part of the 9800 configuration.

    From the GUI:

    Navigate to Configuration > Security > AAA and from the AAA Method List > Authorization tab, create an authorization method similar to the one showed.

    a default network authorization method

     

    From the CLI:

    WLC#configure terminal
WLC(config)#aaa authorization network default group radius

    ISE Configuration

    When implementing dACLs in wireless environment with ISE, two common configurations are possible, to know:

    1. Per-user dACL configuration. With this, each particular identity has a dACL assigned thanks to a custom identity field.
    2. Per-result dACL configuration. While opting for this method, a particular dACL is assigned to a user based on the authorization policy it matched on the policy set used.

    Per-user dACLs

    Step 1. Define a dACL Custom User Attribute

    To be able to assign a dACL to a user identity, first this field must be configurable on the identity created. By default, on ISE, the "ACL" field is not defined for any new identity created. To overcome this, one can use the "Custom User Attribute" and define a new configuration field. To do so, navigate to Administration  > Identity Management  > Settings  > User Custom Attributes. Use the "+"button to add a new attribute similar to the one showed. In this example, the name of the custom attribute is ACL.

    ACL custom attribute in ISE

     

    Once this configured, use the "Save" button to savethe changes.

    Step 2. Configure the dACL

    Navigate to Policy  > Policy Elements  > Results  > Authorization  > Downloadable ACLs to see and define dACL on ISE. Use the “Add” button to create a new one.

    Add a downloadable ACL

    This opens the “New Downloadable ACL” configuration form. On this one, configure these fields:

    • Name: the name of the dACL defined.
    • Description (optional): a brief description about the usage of the created dACL.
    • IP version: the IP protocol version used in the defined dACL (version 4, 6 or both).
    • DACL Content: the content of the dACL, as per Cisco IOS XE ACL syntax.

    In this document, the dACL used is "ACL_USER1" and this dACL allows any traffic except the one destinated to 10.48.39.186 and 10.48.39.13.

    Once the fields configured, use the “Submit” button to create the dACL.

    Repeat the step to define the dACL for the second user, ACL_USER2, as showed in the figure.

    Downloadable ACLs USer1 and 2

    Step 3. Assign the dACL to a Created Identity

    Once the dACL created, one can assign it to any ISE identity using the User Custom Attributes created in Step 1. To do so, navigate to Administration  > Identity Management  > Identities  > Users. As usual, use the “Add” button to create a user.

    Add a network user

    On the “New Network Access User” configuration form, define the username and password for the created user. Use the custom attribute “ACL” to assign the dACL created in Step 2 to the identity. In the example, the identity USER1 using ACL_USER1 is defined.

    Define the ACL inside the user details

    Once the fields configured properly, use the “Submit” button to create the identity.

    Repeat this step to create USER2 and assign ACL_USER2 to it.

    2 Network users

    Step 4. Configure authorization policy result.

    Once the identity configured and the dACL assigned to it, the authorization policy must still be configured in order to match the custom user attribute “ACL” defined to an existing authorization common task. To do so, navigate to Policy >  Policy Elements  > Results  > Authorization  > Authorization Profiles. Use the “Add” button to define a new authorization policy.

    • Name: the name of the authorization policy, here “9800-DOT1X-USERS”.
    • Access Type: the type of access used when this policy is matched, here ACCESS_ACCEPT.
    • Common Task: match “DACL Name” to InternalUser:<name of custom attribute created> for internal user.According to the names used in this document, the profile 9800-DOT1X-USERS is configured with the dACL configured as InternalUser:ACL.

    Create a dot1x authorization profile

    Step 5. Use authorization profile in policy set.

    Once the authorization profile result correctly defined, it still needs to be part of the policy set used to authenticate and authorize wireless users. Navigate to Policy  > Policy Sets and open the policy set used.

    Here, the authentication policy rule "Dot1X" matches any connection made via wired or wireless 802.1x. The authorization policy rule "802.1x Users dACL" implements a condition on the SSID used (that is Radius-Called-Station-ID CONTAINS DACL_DOT1X_SSID). If an authorization is performed on the "DACL_DOT1X_SSID" WLAN, then the profile "9800-DOT1X-USERS" defined in Step 4 is used to authorize the user.

    ISE_Policy_Set

    Per-result dACLs

    To avoid the tremendous task of assigning a particular dACL to each identity created on ISE, one can opt for applying the dACL to a particular policy result. This result is then applied based on any condition matched on the authorization rules from the policy set used.

    Step 1. Configure the dACL

    Execute the same Step 2 from the Per-user dACLs section  in order to define the dACLs needed. Here, these are ACL_USER1 and ACL_USER2.

    Step 2. Create identities

    Navigate to Administration  > Identity Management  > Identities  > Users and use the “Add” button to create a user.

    Add a network user

    On the “New Network Access User” configuration form, define the username and password for the created user.

    Set a login password

    Repeat this step to create USER2.

    Network access user 1 and 2

    Step 4. Configure the authorization policy result.

    Once the identity and the dACL configured, the authorization policy must still be configured in order to assign a particular dACL to user matching the condition to use this policy. To do so, navigate to Policy >  Policy Elements  > Results  > Authorization  > Authorization Profiles. Use the “Add” button to define a new authorization policy and complete these fields.

    • Name: the name of the authorization policy, here “9800-DOT1X-USER1”.
    • Access Type: the type of access used when this policy is matched, here ACCESS_ACCEPT.
    • Common Task: match “DACL Name” to “ACL_USER1” for internal user. According to the names used in this document, the profile 9800-DOT1X-USER1 is configured with the dACL configured as “ACL_USER1”.

    Choose the DACL name

    Repeat this step to create the policy result “9800-DOT1X-USER2” and assign “ACL_USER2” as DACL to it.

    gdefland_4-1710947835593

    Step 5. Use authorization profiles in policy set.

    Once the authorization profile results correctly defined, it still needs to be part of the policy set used to authenticate and authorize wireless users. Navigate to Policy  > Policy Sets and open the policy set used.

    Here, the authentication policy rule "Dot1X" matches any connection made via wired or wireless 802.1X. The authorization policy rule "802.1X User 1 dACL" implements a condition on the username used (that is InternalUser-Name CONTAINS USER1). If an authorization is performed using the username USER1, then the profile "9800-DOT1X-USER1" defined in Step 4 is used to authorize the user and thus, the dACL from this result (ACL_USER1) is applied as well to the user. The same is configure for username USER2, for which "9800-DOT1X-USER1" is used.

    Notes About Using dACLs with CWA SSIDs

    As described in the Configure Central Web Authentication (CWA) on Catalyst 9800 WLC and ISE configuration guide, CWA relies on MAB and particular result to authenticate and authorize users. Downloadables ACLs can be added to the CWA configuration from ISE side identically as what has been described above.

    warning-icon

    Warning: Downloadable ACLs can only be used as network access list and are not supported as pre-authentication ACLs. Therefore, any pre-authentication ACL used in a CWA workflow must be defined in the WLC configuration.

    Verify

    To verify the configuration made, these commands can be used.

    # show run wlan
# show run aaa
# show aaa servers
# show ap config general
# show ap name <ap-name> config general 
# show ap tag summary
# show ap name <AP-name> tag detail
# show wlan { summary | id | nme | all }
# show wireless tag policy detailed <policy-tag-name>
# show wireless profile policy detailed <policy-profile-name>
# show access-lists { acl-name }

    Troubleshoot

    Checklist

    • Ensure clients can connect properly to the 802.1X SSID configured.
    • Ensure the RADIUS access-request/accept contain the proper attribute-value pairs (AVPs).
    • Ensure clients use the proper WLAN/policy profile.

    WLC One Stop-Shop Reflex

    To check if the dACL is properly assigned to a particular wireless client, one can use the show wireless client mac-address <H.H.H> detail command as shown. From there, different useful troubleshooting information can be seen, namely: the client username, state, policy profile, WLAN and, most importantly here, the ACS-ACL.

    WLC Show Commands

    To see all ACLs which are currently part of the Catalyst 9800 WLC configuration, you can use the show access-lists command. This command lists all ACLs defined locally or dACLs downloaded by the WLC. Any dACLs downloaded from ISE by the WLC has the format xACSACLx-IP-<ACL_NAME>-<ACL_HASH>.

    note-icon

    Note: Downloadable ACLs remain in the configuration as long as a client is associated and uses it in the wireless infrastructure. As soon as the last client using the dACL leaves the infrastructure, the dACL is removed from the configuration.

    Conditional Debugging and Radio Active Tracing 

    While troubleshooting configuration, you can collect radioactive traces for a client supposed to be assigned with the dACL defined. Here are highlighted the logs showing the interesting part of the radioactive traces during the client association process for client 08be.ac14.137d.

    Packet capture

    Another interesting reflex is to take and analyze packet captures of the RADIUS flow for a client association. Downloadable ACLs rely on RADIUS, not only to be assigned to a wireless client but also to be downloaded by the WLC. While taking packet capture for troubleshooting dACLs configuration, you must therefore capture on the interface used by the controller to communicate with the RADIUS server. This document shows how to configure easily embedded packet capture on the Catalyst 9800, which have been used to collect the capture analyzed in this article.

    RADIUS client authentication

    You can see the client RADIUS access-request sent from the WLC to the RADIUS server in order to authenticate the user USER1 (AVP User-Name) on the DACL_DOT1X_SSID SSID (AVP NAS-Identifier).

    RADIUS-Access-Request

    When the authentication succeeds, the RADIUS server replies with an access-accept, still for user USER1 (AVP User-Name) and applying the AAA attributes, in particular the vendor specific AVP ACS:CiscoSecure-Defined-ACL being here "#ACSACL#-IP-ACL_USER1-65e89aab".

    RADIUS-Access-Accept

    DACL Download

    If the dACL is already part of the WLC configuration, then it is simply assigned to the user and the RADIUS session ends. Otherwise, the WLC downloads the ACL, still using RADIUS. To do so, the WLC makes a RADIUS access-request, this time using the dACL name ("#ACSACL#-IP-ACL_USER1-65e89aab") for the AVP User-Name. Along with this, the WLC informs the RADIUS server that this access-accept initiates an ACL download using the Cisco AV pair aaa:event=acl-download.

    RADIUS-Access-Accept

    The RADIUS access-accept sent back to the controller contains the dACL requested, as shown. Each ACL rule is contained inside a different Cisco AVP of type "ip:inacl#<X>=<ACL_RULE>", <X> being the rule number. 

    RADIUS-Access-Accept_DACL

    note-icon

    Note: If the content of a download ACL is modified after it has been downloaded on the WLC, the change for this ACL is not reflected until a user using this one re-authenticates ( and the WLC perform a RADIUS authentication for such a user again). Indeed, a change in the ACL is reflected by a change in the hash part of the ACL name. Therefore, the next time this ACL is assigned to a user, its name must be different and thus, the ACL must not be part of the WLC configuration and is supposed to be downloaded. However, clients which authenticate before the change on the ACL continue to use the previous one until they fully re-authenticate.

    ISE Operation Logs
