Note Note Monitoring Resources When Insufficient Resources Are Available When Insufficient Resources Are Available The switch has ample resources for configuring features and supporting: ■ RADIUS-authenticated clients (with or without the optional IDM applica- tion) ■ Virus throttling and blocking on individual clients. Virus throttling does not operate on IPv6 traffic. If the resources supporting these features become fully subscribed: ■ The current feature configuration, RADIUS-authenticated client sessions, and virus throttling instances continue to operate normally. ■ The switch generates an event log notice to say that current resources are fully subscribed. ■ Currently engaged resources must be released before any of the following actions are supported: • Configuration of new entries for QoS, IDM, virus throttling, and other features (Management VLAN, DHCP snooping, dynamic ARP protection). • Acceptance of new RADIUS-based client authentication requests (displayed as a new resource entry for IDM). Failure to authenticate a client that presents valid credentials may indicate that insufficient resources are available for the features configured for the client in the RADIUS server. To troubleshoot, check the event log. • Throttling or blocking of newly detected clients with a high rate of connection requests (as defined by the current virus-throttling configuration). The switch continues to generate event log notifications (and SNMP trap notification, if configured) for new instances of high connectionrate behavior detected by the virus-throttling feature. E-3
