Force unit to Fail back to Ethernet

  • 1.  Force unit to Fail back to Ethernet

    Posted Apr 08, 2019 05:32 PM

    Hello,

     

    We use our Aruba APs in a way that has a 3g/4g USB Modem Dongle for backup, and on the Eth0 port we use it as a primary Internet (broadband modem). The Aruba is designed to failover to the 3g/4g once the primary stops responding. Problem with that is that once the site fails over, sometimes it will not fail BACK to the Ethernet once the ethernet is back up. See the config below for example:

     

    aruba# sho uplink status
     
    Uplink preemption :enable
    Uplink preemption interval :600
    Uplink enforce :none
    Ethernet uplink eth0 :DHCP
    Uplink Table
    ------------
    Type State Priority In Use
    ---- ----- -------- ------
    eth0 UP 21 No
    Wifi-sta INIT 23 No
    3G/4G UP 22 Yes
    Internet failover :enable
    Internet failover IP :8.8.4.4
    Max allowed test packet loss :10
    Secs between test packets :10
    VPN failover timeout (secs) :180
    Internet check timeout (secs) :10
    ICMP pkt sent :213
    ICMP pkt lost :0
    Continuous pkt lost :0
    VPN down time :0
    AP1X type:NONE
    Certification type:NONE
    Validate server:NONE
    Subway 47671# sho port stat
     
    Port Status
    -----------
    Port Type Admin-State Oper-State STP-State
    ---- ---- ----------- ---------- ---------
    eth0 GE up up Off
    eth1 GE up up Off
    eth2 GE up down Off
    eth3 GE up up Off
     
    aruba# show uplink config
     
    Uplink preemption :enable
    Uplink preemption interval :600
    Uplink enforce :none
    Ethernet uplink eth0 :DHCP
    Internet failover :enable
    Internet failover IP :8.8.4.4
    Max allowed test packet loss :10
    Secs between test packets :10
    VPN failover timeout (secs) :180
    Internet check timeout (secs) :10
    aruba#
     
    It shows eth0 as Up/Up but is not comming back online. Is there a CLI command that I can imput to attempt to force it back to the primary internet without having to reboot (which is currently what we do to fix this)? Any input would be greatly appreciated.
