Display exports access cache configuration

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

The vserver export-policy access-cache config show command displays the timeout attributes related to the exports access cache. The access cache maintains export rules applicable to a client that is accessing the volume or qtree. The command output displays the following timeout parameters and their values for each Vserver:

  • TTL for Positive Entries: This is the TTL for positive entries in the access cache. During client access, if the TTL for the access cache entry that is allowing access has expired, that access cache entry will be refreshed. While the refresh is in progress, client access will be evaluated with the existing information in the access cache entry.

  • TTL for Negative Entries: This is the TTL for negative entries in the access cache. During client access, if the TTL for the access cache entry that is denying access has expired, that access cache entry will be refreshed. While the refresh is in progress, client access will be evaluated with the existing information in the access cache entry.

  • TTL for Entries with Failure: This is the TTL for access cache entries for which a failure was encountered while trying to get matching rules.

  • Harvest Timeout: If Data ONTAP does not use an entry that is stored in the access cache for this period of time, it deletes the entry.
