Clearing Persistence Sessions

Nov 23, 2015
You might need to clear persistence sessions from the NetScaler if sessions fail to time out. You can do one of the following:
  • Clear all sessions for all virtual servers at once.
  • Clear all sessions for a given virtual server at once.
  • Clear a particular session that is associated with a given virtual server.

To clear a persistence session by using the command line interface

At the command prompt, type the following commands to clear persistence sessions and verify the configuration:

  • clear lb persistentSessions [<vServer> [-persistenceParam <string>]]
  • show persistentSessions <vServer>

Examples

Example 1 clears all persistence sessions for load balancing virtual server lbvip1. Example 2 first displays the persistence sessions for load balancing virtual server lbvip1, clears the session with persistence parameter xls, and then displays the persistence sessions to verify that the session was cleared.
