Known Issues

 

This section lists the known issues in hardware and software in Junos OS Release 17.1R2 for the ACX Series Universal Metro Routers.

For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.

Network Address Translation (NAT) and Stateful Firewall Services

  • On the ACX500 routers, when service application logging is enabled at [edit services service-set service-set-name syslog host host-name class] hierarchy level and when packets containing errors are received at higher rate toward the service engine, the resource scale requirements at the service engine cannot be met and the service processor might reboot. As a workaround, you can disable the application logging. PR1223500

  • On the ACX500 routers, when there is a fast ramp-up of scaled user applications, the resource requirements of the service engine cannot be met. As a workaround, you can disable the application logging. PR1226153

Generic Routing Encapsulation

  • Traffic loss is seen after restarting the chassis-control when 64 gr- logical interfaces are configured. This occurs when you restart the Packet Forwarding Engine (PFE) and when there are multiple gr- logical interfaces configured. The traffic automatically resumes once all the ARP entries for the traffic are learned. PR1228216

Firewall

  • On the ACX5000 line of routers, if you apply firewall filter to an interface using input-list at the [edit interfaces interface-name unit unit-name family ethernet-switching filter] hierarchy level, then commit does not happen. PR1037604

Layer 2 Features

  • On the ACX5000 line of routers, when you issue the show ethernet-switching table summary vlan-name CLI command, an l2ald.core.0.gz core is generated. PR1042995

  • When interface flaps or process restarts occurs, the interface configured for RSTP with root protection may not transit to DESG state. There is no workaround available.PR1223137

MPLS

  • The link protection does not work properly when auto bandwidth is configured on the ACX5000 line of routers. After the interface disable has been deleted, the backup will remain active for 90 seconds. The auto-adjustment of bandwidth does not happen at the first instance when the auto-adjustment timer expires and the bandwidth is adjusted only at the second instance when the timer expires. PR1233761

SNMP

  • ACX Series routers do not have control board and when you issue the show snmp mib walk jnxOperatingState CLI command, the parameter always shows online.

    The following is an example of the show snmp mib walk jnxOperatingState CLI command output:

    PR1191995

Timing and Synchronization

  • When you run the restart clksyncd-service CLI command, incorrect correction field values are seen when transparent clock is INACTIVE. This does not have any functional impact. PR1067583

  • When interface flaps or process restarts occurs, the interface configured for RSTP with root protection may not transit to DESG state. There is no workaround available.PR1223137
