    Posted Sep 25, 2023 10:45 AM


    I have Aruba switch CX 6100 and switch won't reachable for any management access. I was connect to switch over console cable (yes really I was must go on place), I am looking for default route

    40# sh ip route 

    Displaying ipv4 routes selected for forwarding

    Origin Codes: C - connected, S - static, L - local

    VRF: default

    Prefix              Nexthop                                  Interface     VRF(egress)       Origin/   Distance/    Age
                                                                                                 Type      Metric
    -------------------------------------------------------------------------------------------------------------------------------                                 vlan120       -                 S         [1/0]        00h:00m:42s        -                                        vlan120       -                 C         [0/0]        -              -                                        vlan120       -                 L         [0/0]        -            
    40# show runn | inc route
    ip route

    BUT ...  I am starting shell and I see that default route not up in system:

    40# start-shell 
    40:~$ ip ro show dev vlan120 proto kernel scope link src dev tap0 proto kernel scope link src 
    40:~$ ip ro ad default via
    RTNETLINK answers: Operation not permitted
    40:~$ sudo ip ro ad default via
    40:~$ ip ro s
    default via dev vlan120 dev vlan120 proto kernel scope link src dev tap0 proto kernel scope link src 
    40:~$ exit

    now is switch management reachable.

    This is a BUG or .....?

    next one with the same fw is unreachable because lost defaul gateway from system. It is realy interesting, i mean that this behavior isn't good. I use cheaper switch from EdgeCore too and those never losed gateway - this is the basic!

    I will be testing new firmware ArubaOS-CX_6100-6000_10_12_1000, however in release notes isn't note about this.
