  • 1.  Problem with DHCP

    Posted 11-04-2020 23:57

    Good afternoon!
    I have Juniper SRX220H, recently started a problem like this:
    Inside the local network, passive ftp sessions suddenly ceased to take place, although all protocols are allowed in trust-to-untrust. The "show chassis routing-engine" command was showing excessive "User" utilization among CPU utilization. After restarting the device, the problem went away, but now the router does not distribute DHCP addresses to devices on the local network. In this case, the DHCP service is running and correctly restarted, and also shows a working address pool.
    What could be the problem?
    technical data:
    Software Version: JUNOS Software Release [12.1X44-D35.5]
    Bios Version: 1.9
