Should an AP reboot when it acquires a new lease?

  • 1.  Should an AP reboot when it acquires a new lease?

    Posted Sep 19, 2018 10:44 AM

    Hi


    Strange one - today all of our RAPS in one office location rebooted.

     

    The lease time is set to 7 days.

     

    All of the other offices AP (RAPS) have an up time of 14 days currently - they are also set to renew a lease every 7 days.

     

    So my question is should the AP of rebooted if it has been given a new IP?  When checking the logs I see the below:

     


    Reboot Information
    ------------------
    AP rebooted Wed Sep 19 14:59:21 UTC 2018; Entering REBINDING state; t1 25197 t2 25200 lease 28800 (saved_ip 192.168.12.18 yiaddr 192.168.12.11 saved_router 192.168.12.1 new_router 192.168.12.1)
    -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

     

    Thanks

    Why would the RAPs not renew their existing IP address? With a 7 day lease, they should be successfully renewing around 3.5 days into the lease. 

     

    If the IP changes, then the connection will be interrupted as a new IPSec connection needs to be negotiated between the RAP and controller for passing the GRE tunnels and PAPI needed.
