SRN - Software Release Notification
Product Affected:Alert Description:
Solution:
Junos Software service Release version 15.1R6-S4 is now available. The following are incremental changes in 15.1R6-S4.
| PR Number | Synopsis | Description |
|---|---|---|
| 1180397 | MPC cell packing error causing send corrupt packets to fabric with multicast or bridge flood traffic | When multicast, vpls-flood or bridge-flood traffic, on an affected FPC type, with packet sizes ranging from 112 - 113 bytes or 108 - 109 bytes crosses zone boundaries within the router, traffic forwarding towards the fabric may stall. The following syslog entry will be reported "FO: Cell packing interface error". The MPC that reports this syslog error message needs to be restarted to recover from this condition. |
| 1221766 | LDP route deletion might cause the rpd process to crash | With Label Distribution Protocol (LDP) enabled, the deletion of an LDP entry (for example, LDP interface down) might cause many LDP entries to be deleted, which might result in routing protocol process (rpd) crash. |
| 1233580 | LCD corruption issue during booting up for EX Series switch | During boot up, EX4200, EX4550, and EX4300 switches might have no display or might display gibberish on the LCD. It is an LCD corruption issue. |
| 1253544 | When console log-out-on-disconnect is enabled, system reboot or switchover can result in processes remaining in the wait state and failure of the syslog feature | When the "set system log-out-on-disconnect" command is enabled, the Junos OS eventd process (daemon) will block the console-open(), but during this stage with syslog console configured (always logs on console), any logging will continue even if the console session has ended. While console logging is in wait state by eventd, syslog rotation freezes and some daemons directly attached to logging in the system would also get into the wait state, causing an undesirable behavior. |
| 1260829 | IPCP/IPv6CP re-negotiation is terminated by MX Series BNG | In a dual-stack PPPoE subscribers environment, when the PPP session has been in "OPEN" state, if the router receives a Conf-Request message from the client, it then sends a Term-Request message as a reply unexpectedly. |
| 1262969 | The packets with certain UDP destination port might be dropped on EX-VC except EX4300/EX4600/EX9200-VC | From Junos OS release 13.2X50-D15, for EX Virtual Chassis (VC) switches except EX4300/EX4600/EX9200-VC, when small UDP (<80 bytes) packets are forwarded between endpoints across Virtual Chassis port (VCP) link, a certain User Datagram Protocol (UDP) destination port gets black holed. |
| 1265386 | The "boot -s" command does not work as expected with 15.1R1 to 15.R6 | On EX2200/EX3200/EX3300/EX4200/EX4500 and EX4550 platform, type "boot -s" from loader prompt can start up the system in single-user mode. The user can setup the password recovery in that mode. If "boot -s" is typed under loader in 15.1R1 ~15.1R6, the system does not go into the single-user mode but reboot from the alternate slice. |
| 1269202 | Dropping the TCP RST packet incorrectly on PFE might cause traffic drop | In rare cases, the Packet Forwarding Engine might drop the TCP RST (reset) packet from the Routing Engine side while doing GRES or flapping an interface, and traffic might be dropped. |
| 1279192 | In scaling VPLS scenario, convergence time is taking more than 10 minutes | In scaling VPLS scenario, convergence time is taking more than 10 minutes (which is expected to be 20secs). And in VPLS topologies the kernel may report the error "pointchange for TLV type 00000052 not supported on IFL " in /var/log/messages where is a VT or LSI interface used by VPLS. Sometimes the issue can be reproduced by simply loading the configuration if the scale is high enough, but other triggers may apply as well. |
| 1294267 | Family inet shows as not-configured after adding or deleting the loopback address. | Family inet showing as Not-configured after adding/deleting the loopback address. |
| 1301717 | All traffic can be Tail-/RED-dropped on some interfaces when 'chassis fpc max-queues' is configured.. | When the total number of available CoS queues on MPC Type 1 or Type 2 with Enhanced Queuing chip (QX chip) is limited with 'chassis fpc max-queues' configuration, some interfaces might start dropping all traffic as Tail-/RED-drops. |
| 1309770 | Subscribers may not be able to access the device if dynamic vlan is used | In the subscriber management scenario a profile-add-request for a dynamic vlan may fail, this can cause subsequent subscribers login for the same vlan to fail. This is due to issues with internal data structure cleanup following the failed profile-adds. |
| 1315009 | L2TP LAC droping packets that have incorrect payload length in 15.1 but are forwarded in 14.1X50 | L2TP LAC droping packets that have incorrect payload length in 15.1 but are forwarded in 14.1X50 |
| 1321392 | IPv6 Framed Interface Id field is not properly showing at "show subscribers extensive" output | Customer, running MX router for BNG/Subscriber Management functionalities, reported that in Dual Stacked subscriber 'IPv6 Framed Interface Id field' (from "show subscribers extensive" output) is not matching the negotiated one. |
