I was upgrade firmware to newest but bug is here still. In logs aren't  nothing useful messages. Very bad is inconsistent information in switch userspace and shell.

    Can you try to set the ip default-gateway, instead of an ip route?

    There is a separation between the management plane (ip default-gateway) and forwarding-plane (ip route), and depending on if 'ip routing' (command) is enabled, it would use the ip route with routing enabled and ip default-gateway with routing disabled. Edit: this was for AOS-Switch, not for AOS-CX.

    On first step i thank you for post. Part of my config:

    interface vlan 120
        ip address 10.2.20.14/24
        arp timeout 300
    snmp-server vrf default
    snmp-server response-source interface vlan120 vrf default
    snmp-server view AllData 1.3.6.1 fe:80 included
    snmp-server community XX01
        access-list ipv4 snmp
        view AllData
    ip route 0.0.0.0/0 10.2.20.1

    What should I change? You write about command ip route default, but this command isnt here.

    From terminal:
    (config)# ip route 
      A.B.C.D    IPv4 route destination 
      A.B.C.D/M  IPv4 route destination

    (config)# ip 
      dns                Enable/disable DNS client 
      ecmp               Configure ECMP 
      icmp               Configure Internet Control Message Protocol (ICMP) 
      igmp               IGMP Configurations 
      route              Configure static routes 
      source-interface   Source-interface configuration 
      tcp                Global TCP parameters. 
      udp-bcast-forward  Enable or disable UDP broadcast forwarding

    I mixed up with ArubaOS-Switch, other operating system. Your config looks good. Can you ping your default gateway 10.2.20.1 when you see the issue?

    It may be good to work with your Aruba partner or Aruba support, as config looks good.

    Yes default gateway is reachable and pingable - I wrote in my first post. It is realy creazy situation - one reboot and switch is unreachable, and most creazy is the fact that in userspace config is reported default gateway as configured.

    Ok I try write to Aruba support and i will hope to stable electric power. In summer, when are too much storm, it isn't easy.
