Known Problems and Limitations


This section lists known problems and limitations identified in SBR Carrier 8.5.0. For the most complete and latest information about known defects, use the Juniper Networks online Problem Report Search application.

LDAP Authentication

  • When you have a large number of LDAP connections configured, SBR Carrier may hang or take several minutes to shut down, and the sbrd script may display a shutdown failure message in the terminal. PR847961


  • The User Concurrency table does not display proxy realm names. PR857901

  • In the rfc4679.dct file, the names of the Agent-Circuit-Id and Agent-Remote-Id attributes are not defined as mentioned by RFC 4679. Instead, the names are respectively mentioned as DSL-Agent-Circuit-Id and DSL-Agent-Remote-Id.

  • Enhanced performance counters initialize peak-rate counter to total-requests counter's value when a HUP signal is sent. PR1052592

  • When the Framed-IPv6-Address attribute is configured in both the user and profile return lists, the IPv6 addresses in both the return lists are returned if the FramedIPv6AddressHint parameter is set to no. For a workaround, see the PR record. PR1303671

  • Web GUI allows users to configure Echo feature for Multi-Valued-Pair attributes though the Multi-Valued-Pair attribute has no support for Echo feature. PR1306874

SIM Authentication

  • The authGateway and GWrelay processes must be restarted whenever SBR restarts. This is applicable only on a Linux platform. PR1011144


  • Detailed EAP logging is supported only for TLS protocol version 1.0, and not for versions 1.1 or 1.2. PR1219412

  • Transaction IDs are not logged for accounting packets when a Class attribute is not present in the packet. PR917748


  • Memory leak issues exist when the Geo-redundancy feature is enabled. PR1377772

3GPP AAA Module

  • The 3GPP AAA module does not initiate subscriber de-registration in the HSS. Subscriber de-registration is performed when SBR Carrier receives an HSS Registration-Termination-Request.

  • The Diameter redirection indication is supported only over the SWx reference point. The redirection indication information in an AA-Answer message, received by a proxy server from SBR Carrier over the SWd reference point, is returned to the client without attempting to forward the request to the Redirect-Host. That is, only routing rules configured by a system administrator are enforced.

  • The Redirect-Host-Usage value included in a Multimedia-Authentication-Answer message and received over the SWx reference points is ignored. The value is assumed to be DONT_CACHE.

  • In the SBR Diameter Administrator, the Permanent Failures, Transient Failures, and Protocol Errors statistics are updated based on Result-Code attribute values (not based on Diameter Experimental-Result-Code attribute values).


  • On a Linux platform, WiMAX HA authentication gets rejected as IP addresses set to the WiMAX-hHA-IP-MIP4 attribute are populated in a reverse order. PR1388743
