Introduction
High Capacity Guest mode supports the high-volume licensing requirements in the public-facing enterprise
environment, where a large volume of unique endpoints require wireless access and the number of endpoints
changes every day, such as airports, hotels, hospitals, and shopping malls (for related information, see
Licensing Considerations).
When High Capacity Guest mode is enabled on a cluster, the count of unique endpoints is reset every day,
providing the ability for a node to support double the number of guest accounts, regardless of whether it’s a
hardware or virtual appliance.
ClearPass Insight
High Capacity Guest mode requires that the W-ClearPass Insight reporting tool must be enabled on at least one
node in the cluster. For instructions on enabling Insight, as well as guidance as to where Insight should be
enabled in the cluster, see Deploying W-ClearPass Insight in a Cluster on page 152.
Restrictions
When High Capacity Guest mode is enabled in a cluster, the following restrictions apply:
l Configuration settings cannot be moved from one cluster to another cluster that operates in High Capacity
Guest mode.
l Restoring configuration data is allowed only with the backup files from W-ClearPass servers that have High
Capacity Guest mode enabled.
l Use case-related settings other than High Capacity Guest mode settings are restricted.
l Access to OnGuard and OnBoard is restricted.
l Default cleanup interval values are reset (see Cleanup Intervals Settings for High Capacity Guest Mode for
details).
l Only Guest application licenses are allowed.
Features Disabled Under High Guest Mode
In allowing double the number of licensed guest users, the following W-ClearPass features are disabled:
l W-ClearPass Onboard
l W-ClearPass OnGuard
l Performing posture checks on endpoints
l Performing audit checks on endpoints
l Service templates to configure 802.1X for both wired and wireless LANs
l The following EAP methods are disabled: FAST, GTC, MSCHAPv2, PEAP, TLS, TTLS
Licensing Considerations
You can add only guest licenses to High Capacity Guest mode. After enabling High Capacity Guest mode, you
cannot add enterprise licenses.
If the number of licenses used exceeds the number of licenses purchased, a warning message appears four
months after the number is exceeded.
The number of licenses used is based on the daily moving average.
In High Capacity Guest mode, a maximum of 2x guest licenses are allowed. For example, if you use the W-
ClearPass 25K hardware appliance (CP-HW-25K) that supports 25,000 licenses, a maximum of 50,000 licenses
would be allowed in High Capacity Guest mode.
