Clients with High Roaming Latency

The Clients experienced high latency while roaming insight can be accessed from the Global, Site, Access Points, and Clients context. This insight provides reports on wireless clients that have experienced long roam times to the target AP. The threshold to detect a delayed and long client roaming is set to 50 ms and all the data and analysis pattern is perceived from the target AP issues if you access this insight from the global, site, or client context. When you access this insight from device context, data is received from the home AP issues. Clients experienced high latency while roaming is categorized under connectivity since it helps the network administrators to take necessary actions if there are any clients experiencing long delays to roam between APs. This insight displays the following information:

Time Series Graph

The time series graph displays the total number of roams and the percentage of high latency roams that occurred in the network during the selected time period. You can hover your mouse on each bar graph to see the exact number and percentage of roams.

Cards

The cards vary based on the context that you access the insight from. Click one of the cards to view further details:

Site

Lists the number of sites where the clients have experience high roaming latency in the network. Click the arrow to view the pictorial graph of the Most Impacted sites. Click the number displayed on the Site card, to view a detailed description of the impacted sites:

  • Site—Name of the site impacted by the insight and link to the specific insight at the site context.
  • High Latency Roams (%)—Number and percentage of high latency roams in each site.
  • Impacted Clients Count—Number of clients impacted with high roaming latency in each site.

Access Point

Lists the number and details of APs where the clients have experience high roaming latency. Click the arrow to view the pictorial graph of the Most Impacted access points. Click the Access Point drop-down list to view the following:

  • Model—Pictorial graph of high roaming latency classified by AP models.
  • FW Version—Pictorial graph of high roaming latency classified by AP firmware versions.

Click the number displayed on the Access Point card to view a detailed description of the impacted access points:

  • AP Name—Name of the access points and link to the specific insight at the AP context.
  • Serial—Serial number of the AP.
  • High Latency Roams (%)—Number and percentage of high latency roams in each AP.
  • Clients From—Number of clients that roamed in each AP.
  • Latency (min/avg/max) msec—The minimum, average, and maximum latency that occurred in each AP.
  • AP MACMAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the impacted AP and link to the specific insight at the AP context.
  • IP—IP address of the impacted AP.
  • Model— Model number of each AP.
  • FW Version—Version of the firmware running on each AP.
  • Site—Name of the site where the AP resides.

Client

Lists the MAC Address, name, host name, auth ID, and the number of clients that have experience high roaming latency. Click the arrow to view the pictorial graph of the Most Impacted clients. Click the number displayed on the Client card, to view a detailed description of the impacted clients:

  • Client Name—Name of the impacted clients and link to the specific insight at the client context.
  • Client MAC—MAC address of the impacted client and link to the specific insight at the client context.
  • High Latency Roams (%)—Number and percentage of high latency roams in each client.
  • Top AP— AP where the client roamed maximum as compared to other APs in the network.

Roam

Displays the percentage of client latency roams in the network. This card includes the raw telemetry feed sorted based on latency at each context.

Click the arrow to expand the Roam card and click the drop-down list, to view the following:

  • Latency—Pictorial graph of latency versus concurrences. Click to expand the latency data.
  • Band—Pictorial graph of clients roaming trends between 2.4 GHz Gigahertz. and 5 GHz.
