Using the default time or increasing the time that the CIFS credential remains in the WAFL credential cache after Data ONTAP updates it improves performance. Performance is improved because Data ONTAP doesn't have to take the time to create a CIFS credential to verify access to a file.
The disadvantage of increasing the time that CIFS credentials remain in the WAFL credential cache is that if you change a user's access rights, the change does not take effect until Data ONTAP updates the WAFL credential cache. In this case, the user might have rights to a file to which you have just denied access.
If you do not expect problems of this type, you can increase the time that the credential entry is valid. If you need to see access right updates as they occur and slower performance is not an issue, you can use a smaller value than the default.
To set how long each WAFL credential cache entry is valid, complete the following step.
| 1 |
options wafl.wcc_minutes_valid n n is the number of minutes you want each entry to be valid. It can range from 1 through 20,160. The default value is 20. |
