show ap client trail-info

show ap client trail-info [<client-mac>]

Description

Use this command to show client activity for debugging purposes.

Syntax

Parameter

Description

<client-mac> MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the client.

Usage Guidelines

Use this command to view client activity history and roaming, including reasons for client deauthentication, and any alerts or errors encountered by that client. Without arguments, the table gives the last entry for a number of clients - limited by buffer space. Include the optional <client-mac> parameter to show additional details for that specific client.

Client-trail information may be available for clients that are no longer active, as the controller saves a limited amount of client data in a buffer. The maximum number of clients for which trail-information is saved is determined by is determined by the controller platform. Each controller saves client trail information for twice the number of active clients supported by that controller platform.

Examples

The following example shows client-trail information for all clients associated with the controller.

(host) #show ap client trail-info
