    1) ENHANCEMENTS
    There’s major change in the way that XMS detects and reports on the online
    status of Access Points.

    XMS uses WebSockets to push configurations to and pull statistics from Access
    Points. Once added to XMS Access Points will initially establish a WebSocket
    connection to XMS and then approximately every fifty seconds sends a
    heartbeat message to XMS to prove that it’s still alive. XMS processes the
    heartbeat and replies to the Access Point. If the Access Point doesn’t get a
    response to it’s heartbeat it will retry and if unsuccessful after a number of
    attempts will try to re-establish the WebSocket connection. If XMS doesn’t
    receive a heartbeat from an Access Point for five minutes it declares it DOWN
    and will wait for a heartbeat before marking it as UP again.

    In previous versions of XMS would assume that Access Points were UP until
    proven otherwise, which could lead to symptoms such as:
    1. After XMS restart APs appear to be UP but then go DOWN after five
    minutes.
    2. Refreshing an AP that was in a DOWN state would successfully refresh
    the APs configuration in XMS and declare the AP UP only to go DOWN
    five minutes later.
    3. Adding a new AP to XMS - the AP would be successfully added only to go
    DOWN five minutes later.
    4. Pushing configurations to APs that were UP due to one of the above
    situations, would fail.

    In case 1-3 above, XMS assumed that the AP(s) were UP, instead of waiting for
    WebSocket connections and heartbeats to be received, before declaring AP(s)
    UP.

    Now, on startup or after discovering a new AP or refreshing an AP that is


    DOWN, XMS will wait for heartbeats to be received before marking Access
    Points as UP. This may take several minutes as APs have a random delay before
    establishing a WebSocket connection and sending its first heartbeat.

    3) PERFORMANCE IMPROVEMENTS AND FIXED PROBLEMS
    Resolved Issues between 8.3.3-8835 and 8.3.5-9251x

    XMSE-2472 Creating an SSID with EasyPass personal created a Filter list with last
    deleted SSID which will create issue in XMS-Cloud.

    XMSE-3469 Web Client error when opening certain profiles

    XMSE-3591 Deleting Secondary DNS server from Web Client does not remove it from
    configuration.

    XMSE-3625 Occasional drops in in the Station Line Chart dashboard widget. Usually
    between 5-15 minutes after the hour.

    XMSE-3645 Back/Restore didn’t preserve Rogue Filtering

    XMSE-3647 Selecting EasyPass for Captive Portal gave an erroneous error about invalid
    URL

    XMSE-3653 Erroneous status message was displayed on Network Settings detail page
    even though settings were correctly applied.

    3
    XMSE-3655 Unable to disable “Enable API access to XMS.” Check box

    4) KNOWN ISSUES
     After backup is restored to a machine with a different IP address from the original,
    Access Point refresh is required to configure all Access Points with new XMS machine
     After EasyPass is configured on an SSID, this SSID could not be used for other captive
    portal types.
     EasyPass Portal should not be deleted in XMS-Cloud until the corresponding SSID is
    deleted from XMS-Enterprise.
     When using EasyPass Personal, SSID statistics data is calculated for Personal SSIDs,
    however these SSIDs will not be displayed in configuration panels
     When an existing Captive Portal is configured on an SSID, EasyPass cannot be used on
    this SSID
     Duplicate Access point entries are displayed when the name of Profiles or AP groups are
    differentiated only by underscored (“_”) and a white space

    5) LIMITATIONS AND CONDITIONS


    The following table shows the maximum number of Access Points supported various
    memory sizes and polling configurations.

    Memory Size Default Pollers Enhanced Pollers


    8GB 200 140
    16GB 700 600
    24GB 1100 1000
    32GB 1200 1050
    48GB 2050 1850

    6) UPGRADE NOTES
     If you are upgrading from a release earlier than 8.1.1, please upgrade to XMS-
    Enterprise 8.1.7 first, with the XMS Upgrade tool.

    4
     The upgrade process can take up to 30 minutes or longer for the Web UI to be
    available. This is due to a one time re-indexing of several statistics tables to improve
    performance. It’s very important not to interrupt the upgrade process as damage
    to the database could result requiring Technical Support.

     If you are using AOS older than 7.6, please upgrade AOS before you upgrade XMS.

     XMS Enterprise 8.x requires SSH credentials to the Access Points to perform
    Discovery. Please make sure you have SSH user(s) configured on the system.

     Upon upgrade from releases prior to 8.2.7, column selection will revert to default.

     Memory requirements for XMS has approximately doubled as XMS now caches the
    last 24 hours data (see chart in the Limitations and Conditions section above).
