Dynamic RADIUS caching allows client authentication via IEEE 802.1X even when there is no data connection to the RADIUS server. RADIUS Accept messages are cached and retained for a defined period (see 2.25.10.3.21 Cache-Lifetime) to allow re-authentication of the respective clients. With MAC-based authentication, clients can re-authenticate on the port even if the RADIUS server is temporarily unavailable.
Important:
Only PAP is supported.
Only MAC-based authentication is supported.
A monitoring or supervision server must be configured (see 2.25.10.3.19 Sup.-Profile).
Note: Under
you can view the current dynamic RADIUS cache. The CLI provides the command show radius-server response-cache for
this purpose, which outputs all individual entries in full. You can limit the output using wildcards. Example: show
radius-server response-cache * testuser shows only the entries for the user "testuser".
