High Availability

  • Insert additional SPC3 in a multinode high availability (HA) setup (SRX5800, SRX5600, and SRX5400)—Starting in Junos OS Release 22.2R1, you can insert SRX5K-SPC3 cards on the SRX5000 line of devices in a multinode HA setup without interrupting traffic.

    You can use the new procedure to insert SPC3 cards when the setup has an encrypted inter-chassis link (ICL) or a non-encrypted ICL.

    In case of an encrypted ICL setup, use the new statement set chassis high-availability hardware-upgrade on both nodes before you add SPC3 cards.

    We've also updated the show chassis high availability information command output to include messages related to SPC3 installation.
