    Posted Dec 09, 2021 08:16 PM
    hi

    we have access switches and APS & Access control, etc... authenticated from Cppm ...  after the authentication switch appears some IPs and not appear others.

    tried many things to check this issue ((upgrade firmware, change configuration & authentication commands)) but still the same issue while the core switch can reach them all but access switches not.

    Kindly check the attachments

    That is a switch feature, not ClearPass. Could it be that those devices have a static IP?

    What type of switch and firmware do you use?

    yes, all of those devices have static IP but as you see most of them not appeared that have IP and the same issue on all switches but we can see their IPs on Core Switch (6410).

    we use access switches (2930M) version wc16.11.0001

    Hi, like HErman said this is a switch feature and no a Clearpass thing but in order to see statically assigned ip address you  may try the command " ip client-tracker "trusted/untrusted". You can read about it here: https://www.manualslib.com/manual/1650280/Hewlett-Packard-Enterprise-Aruba-2920.html?page=355.

    Hope this helps.

    Hi, you could see the reason, maybe, in 2 places:
    1.- Debug the radius authentication packets in the switch to know why the switch is blocking the port.
    2.- Check in Clearpass in Access tracker to see the reason of the reject, if any.

    Hope this helps

    Hi ulises 

    They got right authentication on switch and no reject logs on clearpass.

    Just blocked AAA on switch log and I don't now why

    Please enable and share the radius authentication debug, not only the show log...

    The commands to debug the radius messages should be similar to this.
    debug security port-access authenticator
    debug security radius-server

    Regards

    Hi, you can see there there is only one reject so your  issue shouldn,t be authentication but in order to be sure ypu need a debug output No a show output to see waht is happening between the switch and Clearpass.

    If you share the debug output when a client is trying to authenticate we may be able to figure out what's happenning.
    Share the log you get in clearpass for the authentication attempt and the switch config

    look here we have a number of ports up but not all of the ports authenticated some authenticated on CPPM and others blocked by Switch ! and no logs on Cppm for those Macs. I don't know why this happened and tried many configurations

    Please share the switch's config and the IP of the CPPM. Also, share the images form the accesss tracker from one of the macs that appeared there: the sumary, the input, output and alerts (if any) tabs

    Hey, you didn't share the switch's config. If the issue is with some ports on the same switch please share all the config.

    Please check the following document and make sure you are not missing any commands and for now remove the radius server with the IP ending in 33 that is jus timing out and test again

    Have you tried to connect a laptop or a phone in thos ports that are blocked by AAA?  Can you see the authentication attemps in clearpass?

    If the test with the laptop and/or phoen work you should open a ticket with TAC and just remember the following:

    * If the authentication request doesn't reach Clearpass is not a Clearpass issue since it works for other ports in the same switch
    * Have at hand the types and models of the devices conencted to the ports that are not sending the authentication requests and remain int he blocking state.

    I think the general config in the switch is fine and is something related to the devices connected in those ports.

    Hope this helps.

    hu ulises,

    thank you, yes I tried to connect my laptop on the blocked port and it worked and I can see the authentication in Cppm but I don't know why I faced this issue in many Access Switch not only one

    Hi, If it works with another device, I think is something realted with the type of device conencted. What is the device or devices connected to the ports that remaing in AAA blocked(remember what Herman said, that is part of the processs: start in blocking state). Have you tried to force traffic from the connected device to the network or to restart the devices and see if there is any difference?

    Please work with your Aruba partner, or Aruba Support (TAC). The Blocked by AAA messages are part of the normal process, but the port should go 'online' quickly after that message.

    With interactive troubleshooting, this probably is easy to solve. It's much harder to solve in this forum by asking back and forth.

    If it takes so long to get a response from Aruba TAC, there probably is something wrong. Please try to phone them or escalate the support case if it was opened.
