Juniper Mist Network Operations

The roaming service-level expectation (SLE) reports an 81% success rate, but its line graph contains data gaps. As the wireless network administrator, you have received no feedback about the network, either positive or negative.

In this scenario, what causes the gaps in the roaming SLE line graph?

  • A Opportunistic Key Caching (OKC) roams are slow, and not meeting the SLE.
  • B No roaming events occurred at those times.
  • C Roaming events are not satisfying the SLE.
  • D The RADIUS server was not available at this time.
Explanation

Roaming SLE data is derived from recorded client roaming events. During intervals in which no clients roam between access points, there are no roaming measurements or success-rate values to plot, so the line graph shows gaps. Failed or slow roaming events would be recorded and reflected in the SLE result rather than creating missing data.
