Fail Open I-SID with Continuity Mode

Fail Open I-SID provides network connectivity with restricted access to devices when the switch cannot connect to a RADIUS server. If a failure occurs that is based on a RADIUS timeout, the port immediately transitions to the Fail Open I-SID.

Note

Note

Prior to releases that support Continuity Mode, transition to the Fail Open I-SID is based on interval-based RADIUS server reachability checks. If the RADIUS server is reachable, the switch continues to check the reachability at a default interval of three minutes. This interval-based check can lead to a transition delay of up to three minutes, from the moment when the RADIUS Server becomes unreachable until the port moves to the Fail Open I-SID.

Note

Note

EAP and NEAP clients are not affected when the RADIUS servers are unreachable.

To use Fail Open I-SID:

Note

Fail Open I-SID is not supported in MHSA mode.

In MHMV mode, the untagged S-UNIs provided by the RADIUS server are treated as MAC-based untagged S-UNIs, which are different from the untagged S-UNIs on the port. Consider the following factors:
