Move AP from Cluster to single controller or deleting nodelist?

  • 1.  Move AP from Cluster to single controller or deleting nodelist?

    Posted Jul 07, 2021 01:20 AM
    Good Morning,

    i have several APs which are managed by a cluster which is build by 3 controllers.
    Now I one branch office got its own controller in local site.
    So i configured dhcp option for the branch office' dhcp scope and reboot aps.
    There is no LMS configured.
    APs stays on cluster.
    So I recognized APs will stay on cluster no matter if there is a dhcp or dns entry to discover a controller because of the nodelist which is present on environmen variables.
    So i "purged" AP via remote CLI commands: 
    provision-ap
    reset-bootinfo 

    AP boots but still keeps connecting cluster.

    So my first question is:

    1.) Does the above mentioned CLI command really purge the env variables?
    2.) What is the best way to move a cluster managed AP to a new single controller?

    Thanks in advance

    When you provision the APs, what is configured in the provisioning parameters. Have you allowed it to use the ADP Process or is a IP/hostname set? Normally, you'd just reboot the AP allow it to locate its controller via DHCP, ADP, DNS etc and off you go.

    Without a controller cluster that is correct. But if an ap once was connected to a cluster it ignores ADP discovery methods.
    But yes ADP is enabled for provisioning but it does not have any effect.

    In that case, can you manually provision it to the branch office controller.

    Have you tried the ap-move command on the active cluster controller?
    It can be used to move the AP inside one cluster, but iirc you can also move an AP from one cluster to another (or to standalone).

    Do you know that the dhcp options are configured correctly or even working?  Did you try with a new AP?

    To figure out why an AP booted to a controller try this:

    show ap consolidated-provision info ap-name <name of ap>

    (7260) *#show ap consolidated-provision info  ap-name Central-lab-535
    
    ap name: Central-lab-535
    ipv4 address type: dynamic
    ipv4 address: 192.168.1.199
    ipv4 netmask: 255.255.255.0
    ipv4 gateway: 192.168.1.1
    ipv4 lease: 86400
    ipv4 dhcp server: 192.168.1.1
    ipv4 dns server: 192.168.1.1, 0.0.0.0
    ipv6 address type: dynamic(RA)
    ipv6 address: 2805:a601:aad5:8e00:aabd:27ff:fec4:a76c/64
    ra dns server: fe80::f7f5:e8ff:fe8b:7b55 
    ipv6 gateway: fe80::f7f5:e8ff:fe8b:7b55
    master preference: IPv4
    Protocol in Use: IPv4(CONFIG)
    master: 192.168.1.7
    master discover type: ADP
    previous lms: 0.0.0.0
    lms addrs [0]: 192.168.1.7

    Hi cjoseph,

    yes dhcp option is working correctly. Seems to be APs are ignoring master ip and use lms node list which points to the cluster where ap was connected before.

    Should provision-ap
    reset-bootinfo 
    delete env variables like purge nvram?

    It does not.  That command only resets environment variables that can be set during provisioning.
