Platform and Infrastructure

  • On QFX5000, in an EVPN_VXLAN deployment, BUM traffic replication over VTEP might send out more packets than expected. PR1570689

  • On EX4600 and QFX5xx0 platforms, you should configure only one static arp with multicast-mac entry per IRB interface. If you configure more than one static ARP with multicast MAC entry per IRB interface, then the packets with different destination IP with static multicast MAC will always go out with any one of the multicast mac configured in the system. PR1621901

  • Unified ISSU on QFX5120-48Y and EX4650 switches will not be supported if there is a change in the Cancun versions of the chipset SDKs between the releases. This is a product limitation as change in the Cancun firmware leads to the chip reset and hence impacts ISSU. The Cancun versions in the chipset SDKs should be the same between two Junos OS releases for ISSU to work. PR1634695
