Service Parameter Action/Description
Machine Authentication
Cache Timeout
1. Specify the time (in hours) for which machine authentication entries are
cached by W-ClearPass Policy Manager.
The default is 24 hours.
LDAP Primary Retry
Interval
After a primary LDAP server is down, the W-ClearPass server connects to one of
the backup servers.
2. Specify how long the W-ClearPass server waits (in seconds) before it tries to
connect to the primary server again.
Audit SPT Default Timeout 3. Specify the time (in seconds) for which an Audit success or error response is
cached in the Policy server.
Additional time before
session deletion from
multi-master cache
4. Specify the number of seconds the Policy server will wait before deleting the
multi-master entry.
The default value is 0.
This parameter handles roaming scenarios where an Accounting-Start occurs
without an authentication request. If the value for this parameter is 0, the
Policy server deletes the multi-master entry when an Accounting-Stop is
received.
The RADIUS server updates the multi-master entry with attribute values from
the accounting request. These can be used in the Change of Authorization
(CoA). In a roaming scenario, this NAS information update from the accounting
request helps W-ClearPass send the CoA to the correct NAS.
Number of request
processing threads
5. Specify the maximum number of threads used to process requests.
HTTP Thread Pool Size 6. Specify the number of threads allotted for the HTTP thread pool.
Authentication Thread
Pool Size
7. Specify the number of threads to use for LDAP/AD and SQL connections.
8. Click Save.
