not able to see TACACS packet on the packet capture on the controller

  • 1.  not able to see TACACS packet on the packet capture on the controller

    Posted Jan 23, 2014 03:10 PM

    Hi Everyone,

     

    I am having issues in authenticating management client. I have decided to run the packet capture on the controller to verify the TACACS+ packet exchange between the controller and the TACACS server. 

     

    I have enabled the packet capture on the controller using the command "packet-capture tcp all"

     

    Still i am not able to see the TACACS packets on the packet capture in the logs.tar file. However i can see other TCP packets. 

     

    I do see somewhere that Radius packets and LDAP packets were captured using the above command but it is mentioned anything about TACACS packet. 

     

    Can you help me out on this why i am not able to see the TACACS packet?

     

    Note: TACACS+ works on TCP protocol.

    Radius uses UDP so you should not be seeing it.  Tacacs uses TCP 49 and if you use the controller packet capture for that(http://community.arubanetworks.com/aruba/attachments/aruba/115/160/1/Packet+Capturing+Options+with+Aruba+Wireless+Networks.pdf), you should be able to find the packet capture in the filter.pcap in the logs.tar
