Configuring RADIUS Server Support for Switch Services Configuring and Using RADIUS-Assigned Access Control Lists Message Invalid Access-list entry length, client < mac-address > port < port-# >. Memory allocation failure for IDM ACL. Meaning Notifies that the string configured for an ACE entry on the Radius server exceeds 80 characters. Notifies of a memory allocation failure for a RADIUS assigned ACL assigned by a RADIUS server performing client authentication. (This message is used in IDM and nonIDM environments.) Causes of Client Deauthentication Immediately After Authenticating ■ ACE formatted incorrectly in the RADIUS server • "from", "any", or "to" keyword missing • An IP protocol number in the ACE exceeds 255. • An optional UDP or TCP port number is invalid, or a UDP/TCP port number is specified when the protocol is neither UDP or TCP. ■ A RADIUS-assigned ACL limit has been exceeded. • An ACE in the ACL for a given authenticated client exceeds 80 characters. • The TCP/UDP port-range quantity of 14 per slot or port group has been exceeded. Monitoring Shared Resources Currently active, RADIUS-based authentication sessions (including ProCurve IDM client sessions) using RADIUS-assigned ACLs share internal routing switch resources with several other features. The routing switch provides ample resources for all features. However, if the internal resources do become fully subscribed, new RADIUS-based sessions using RADIUS-assigned ACLs cannot be authenticated until the necessary resources are released from other applications. 6-30
