[. . . ] [Defect ID 67157] The output of the show atm arp command displays only 4096 entries when the line module is configured with more than 4096 NBMA ARP entries. [Defect ID 68849] 34 Known Problems and Limitations Release 10. 3. 1 When you use the no-authenticate keyword with the subscriber command to prevent subscriber authentication so that the subscriber information can be used for DHCP option 82, suboption 2, the SRP module can reset. This issue does not occur when you use the no-authenticate keyword with the subscriber command as a way to perform a RADIUS configuration. [Defect ID 69865] When you perform an snmpWalk on the juniAtmSubIfVccTable, a response is received for only a few of the total configured ATM subinterfaces when both of the following are true: the router has a line module that has some ATM-related configuration and the line module is in the disabled state. [Defect ID 80020] The baseline interface atm command fails for a VCD assigned by the router to F4 OAM circuits. [Defect ID 174482] Unified ISSU is not supported when ILMI is configured on ATM interfaces. [Defect ID 176007/177297/177122] ATM line modules reset after unified ISSU completes at the LAC when an MLPPP bundle with three links are tunneled to the LNS. [Defect ID 178821] For PPPoE, the AAL5 inPacket Discards counter might increment erroneously during call setup when a packet is passed directly to PPPoE for negotiation rather than being discarded. [Defect ID 51757] Work-around: Incremental InPacketDiscards during call setup do not necessarily indicate a problem. However, we recommend you investigate an excessive count because that might indicate a connection that cannot be successfully brought up for some reason, such as RADIUS denials or improper configuration. The inPacketOctetDiscards counter in the output of the show atm vc atm interface vcd command includes both inBytesDropped and inBytesUnknownProtocol statistics. The inBytesUnknownProtocol statistics should be displayed by a separate counter. At the major interface level, the inPacketDiscards counter includes both inPacketsDropped and inPacketUnknownProtocol statistics. The inPacketUnknownProtocol statistics should be displayed by a separate counter. [Defect ID 44286] When you configure an ATM PVC where PCR = SCR and maximum burst size is zero, the CLI returns an error indicating the burst size is invalid and it does not create the VC. [Defect ID 58357] Work-around: Configure a CBR or a UBR plus PCR to create the circuit with the same parameters, depending on the desired priority for the traffic. CBR has a high priority and UBR plus PCR has a medium priority. BFD After you have shut down the interface to the next hop (for the route that is used to establish the BFD session), output for the show bfd session command erroneously indicates the shutdown interface as Management Interface (FastEthernet 6/0). [Defect ID 174271] Known Problems and Limitations 35 JUNOSe 10. 3. 1 Release Notes Bridged Ethernet The CLI erroneously permits you to configure bridge1483 encapsulation over AAL5MUX IP even though that configuration is not supported. [Defect ID 35013] CLI When you issue a run show ppp command, the CLI changes the configuration level of the command line to Global Configuration mode rather than remaining at the level from which you issued the command. [Defect ID 52165] Work-around: Reissue the commands necessary to reenter the desired mode. The logout subscribers all command may not log out all of the DHCP subscribers. Although the bindings and DHCP addresses are cleared, the show subscribers summary command may display some of the DHCP subscribers. [. . . ] The capability to receive line rate data, when it changes on the access node, is disabled by default on the SRC client. Configuring the SRC Client to Retrieve DSL Information from Access Nodes 109 JUNOSe 10. 3. 1 Release Notes The access node passes the DSL line rate parameters, whenever they change, to the SRC client. The SRC client appends updated parameters to the COPS messages that it sends to the COPS server or SRC server. A COPS server processes the following topology parameters that it receives from the SRC client in the updated COPS messages: junoseIpInterfaceMode junoseIpInterfaceUpstreamRate junoseIpInterfaceDownstreamRate junoseIpInterfaceMinimumDataRateUpstream junoseIpInterfaceMinimumDataRateDownstream junoseIpInterfaceAttainableDataRateUpstream junoseIpInterfaceAttainableDataRateDownstream junoseIpInterfaceMaximumDataRateUpstream junoseIpInterfaceMaximumDataRateDownstream junoseIpInterfaceMinimumLowPowerDataRateUpstream junoseIpInterfaceMinimumLowPowerDataRateDownstream junoseIpInterfaceMaximumInterleavingDelayUpstream junoseIpInterfaceActualInterleavingDelayUpstream junoseIpInterfaceMaximumInterleavingDelayDownstream junoseIpInterfaceActualInterleavingDelayDownstream junoseIpInterfaceDSLlinestate A COPS server that runs an SRC software release earlier than Release 3. 0. 0 does not support and process the preceding topology parameters that are appended to the COPS messages. Such COPS servers analyze the information, other than the parameters that describe updated DSL line rate details, that they receive in the COPS messages for policy management. [. . . ]
