Enables retention of client-history. A typical NSight-server enabled, guest access environment may be visited by thousands of unique clients on a daily basis. Some of these guest clients are not regular visitors, accessing the network infrequently. However, by default, historical data of all guest clients, irrespective of their network access frequency, is retained by the NSight server for up to 180 days. This results in the database containing thousands if not millions of unique MAC addresses of infrequent guest clients. To address this potential problem it is recommended to disable client-history retention on a guest WLAN, and use the nsight-policy context to configure a separate timer (8 hours by default) specifying the guest client data lifespan in the database.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000


nsight client-history


nsight client-history
nsight client-history Enables retention of client-history in the database. This option is enabled by default.


On a WLAN, the client-history option is enabled by default. When enabled, all client history (including guest-clients) is retained in the NSight server database for 180 days.

To disable this option, execute the no > nsight > client-history command. When disabled, guest client history is retained only for 8 hours, which is the default setting defined by the NSight policy applied on the access point (through which the guest client accesses the WLAN) or the access point‘s RF Domain. However, the default historical data retention duration for regular clients and devices (access point and controllers) remains unchanged (180 days) as per the NSight policy settings.

Use the NSight policy context to define separate client-history retention time for regular clients, devices, and guest clients. For more information, see nsight-policy (global-config-mode).
