The ME60 Receives the Webpage Redirection Sent by the Radius but the Redirection Is Invalid Because the DNS Is not Configured

Publication Date:  2012-07-27 Views:  60 Downloads:  0
Issue Description
The ME60 receives the redirection attributes 26-27 sent by the Radius. When the user access network, the first webpage cannot be redirected to the specified webpage.
      
Alarm Information
Null
Handling Process
1. Run the debug radius packet command on the ME60. The attributes 26-27 sent by the Radius are as follows:
ID      : 233
  [Session-TimeOut(27)                ] [6 ] [43201]
  [Input-Average-Rate(26-2)           ] [6 ] [524288]
  [Input-Peak-Rate(26-3)              ] [6 ] [524288]
  [Output-Average-Rate(26-5)          ] [6 ] [2097152]
  [Output-Peak-Rate(26-6)             ] [6 ] [2097152]
  [PortalURL(26-27)                   ] [27] [http://gstest.com]
  [Radius-Mp-VT-Number(26-30)         ] [6 ] [0]
  [Service-Type(6)                    ] [6 ] [2]
  [Framed-Protocol(7)                 ] [6 ] [1]
  [Framed-Netmask(9)                  ] [6 ] [255.255.255.0]
  [Unknow-attr                        ] [6 ] [00000000]
  [Unknow-attr                        ] [6 ] [000005dc]
  [Unknow-attr                        ] [6 ] [00000001]
The attributes are distributed correctly. The ME60 cannot resolve the domain name http://gstest.com; thus, the ME60 cannot redirect the user page to the page.
2. Configure dns resolve on the ME60:
 dns server 202.100.64.68     //DNS address
 dns domain com
 dns domain net
 dns domain cn
After the configuration is complete, the user page can be directed to the specified page.
Root Cause
1. The attributes sent by the Radius are incorrect.
2. The ME60 cannot correctly resolve the redirected webpage.
Suggestions
When the ME60 receives the attributes 26-27 sent by the Radius, if the ME60 receives a domain name, the Domain Name System (DNS) should be configured on the ME60. Then the user page can be redirected to the specified page.
