Check the Role Assigned to Client
2.
Check if Client Can Reach the Gateway IP
3.
Check the Firewall Rules of the User Role
Check the Role Assigned to Client
Run the
show clients
command to view clients connected to the AP and verify if the client has inherited
the desired role. For SSIDs with a captive portal, ensure that the client has completed authentication and is
assigned a post auth role.
Check if Client Can Reach the Gateway IP
Routing errors may prevent the client from passing traffic in the network. Ping the default gateway
IP address from the client and check the ping information. If the ping to the default gateway IP address fails,
check the routing profile of the AP.
Check the Firewall Rules of the User Role
Check if the firewall rules of the user role allow the user to pass the desired traffic.
The following procedure describes how to check firewall rules for a user role:
1. Run the
show datapath user
command to view the datapath information of clients connected to
the access point.
2. Identify the ACL number assigned to the client from the
ACLs
column of the
Datapath User Table
Entries
table.
3. Check the access control entries in the ACL using the
show datapath acl <acl number>
command.
4. Verify if the ACL rules are configured to allow the desired traffic.
Wireless Client Fails 802.1X Authentication
The following procedure describes how to troubleshoot issues, if the wireless client fails 802.1X
authentication:
1.
Check Authentication Process Logs on the AP
2.
Check the Status of the RADIUS Server
3.
Debug the RADIUS Packets of the Client
Check Authentication Process Logs on the AP
Check the authentication logs to view and identify errors in the authentication process between the client,
the AP, and the radius server.
Run the
show ap debug auth-trace-buff <MAC address>
command to view the authentication process
logs between the client and the AP. Use the MAC address of the client to filter packets specific to a client.
Any error in the authentication process will be displayed in the output.
Check the Status of the RADIUS Server
Ping the RADIUS server from the AP or run an authentication server test for the RADIUS server.
Run the
aaa test-server
command to the test the authentication server. The following command syntax is
used to test the RADIUS server:
