General Routing

  • High FPC CPU utilization might be seen on PTX10002-60C routers. PR1585728

  • IS-IS adjacency does not come up through TCC Layer 2 circuit. PR1590387

  • High FPC CPU utilization might be intermittently observed if you receive a great number of NS/NA messages. PR1600318

  • On PTX10002-60C routers, after upgrading, configured firewall filters might be applied on incorrect interfaces. PR1602292

  • The FPC is not fully offline after the FPC BAD_VOLTAGE fault is reported. PR1602556

  • Packet loss might be observed on a filter-based GRE deployments. PR1603453

  • Traffic loss might be seen on the device due to the continuous errors happening on fabric healing process (FHP) phase-1. PR1603499

  • The MACsec session might be dropped due to one way congestion. PR1611091

  • Line cards might be unstable due to the continuous growing memory usage of evo-cda-bt app. PR1614952

  • The rasd processes memory leak triggered by hardware memory errors on VMHost platforms. PR1615488

  • Slow memory leak (32 bytes each time) of rpd might be seen. PR1616065

  • Memory leak might be seen when LLDP is configured. PR1617151

  • The performance of J-Flow service might be impacted on PTX Series platforms. PR1617932

  • Traffic loss might be observed with some MPLS labels in multipath BGP scenarios. PR1618507

  • The EAPol packets over l2circuit might get dropped at the tunnel start. PR1628196

  • The rpd process generates core file with the warm-standby configurations due to reference counting issues. PR1631871

  • The SPMB might crash immediately after a switchover. PR1637950

MPLS
