Re-tagging Server to Client Traffic

  • 1.  Re-tagging Server to Client Traffic

    Posted May 24, 2016 10:36 AM

    ODBC traffic from a SQL server to wi-fi clients is tagged AF23 by the LAN.  When it arrives at controller I need to re-tag the traffic so that it arrives to the client as DSCP '0'.  The user role contains the following firewall policy:

     

    ip access-list session odbc_server
    alias odbc_srvs user tcp 1433 permit tos 0 dot1p-priority 0
    !

     

    The traffic is still arriving to the client as AF23.  I swear I've been able to get this to work for other server-to-client traffic flows, but need a sanity check.

    Type "show datapath session table <ip address of client>" to see how it is being tagged.

    From server to client: DSCP 22

    I just checked the other traffic that I said was being re-tagged properly and the DSCP value is not changing.  I was quite sure I had tested this and was able to successfully retag traffic towards the wi-fi client.
