Infrastructure

  • When upgrading from releases before Junos OS Release 21.2 to Junos OS Release 21.2 and onward, validation and upgrade might fail. The upgrade requires using the no-validate option to complete successfully. https://kb.juniper.net/TSB18251. PR1568757

  • On SRX380, the autonegotiation status on the 1G or 10G ports may be incorrectly displayed as Incomplete. This has no impact to traffic. PR1703002

  • BCM5342X SOC port configurations, BCM53426 don't have QSGMII interface. Only the QSGMII port supports half-duplex mode. SRX340 and SRX345 have only SGMII interface, hence half-duplex is not supported. PR1716094
