nsight
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 on the following devices:
- Access Points: AP5010, AP310i/e, AP410i/e, AP505i, AP510i, AP510e, AP560i, AP6522, AP6562, AP7161, AP7502,
AP7522, AP7532, AP7562, AP7602, AP7612, AP7622, AP763, AP7662, AP8163, AP8543,
AP8533.
- Service Platforms:
NX5500, NX7500, NX9500, NX9600
- Virtual Platforms: CX9000, VX9000
Syntax
nsight client-history
Parameters
nsight client-history
| nsight client-history |
Enables retention of client-history in the database. This option is enabled by
default. |
Examples
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).
