Now, if you don't set reauth, it should basically be indefinite. That's on … Where in ISE do I configure the timer? Listen: https://smarturl.it/CCRS7E42A critical component of any zero-trust strategy is securing the workplace that everyone and everything connects to. Hello, I have a problem where the switch will try to authenticate a device with MAB and it will never fail or timeout. Here is the situation: where a device has 802.1x authentication enabled but not it has invalid parameters (or missing certificate). Why is reauthentication needed? ... see Cisco & F5 Deployment Guide: ISE Load Balancing Using BIG-IP. The reauthentication timer displayed is not a standard recommendation, ... Use Case 2 - The switch is configured with order MAB DOT1X and priority DOT1X MAB (Wired). The default reauthentication timer on switchports are 3600 seconds. https://supportforums.cisco.com/discussion/11974106/ise-reauthentication-timer In trying to enter a long timer, ISE limits it to 1-65535 seconds So, at max value a little over 18 hours.

That's also what I've noticed in the repeat count report on ISE that most devices with repeats are MAB-Devices and sometimes in between there are 802.1X-Devices. S7|E42 ISE 3.0 Simplifies the Zero-Trust Workplace Announcing ISE 2.7 as Recommended Release. Leaving this value at 30 seconds provides a default wait of 90 seconds (3 x tx-period) before a switchport will begin the next method of authentication, and begin the MAB process for non-authenticating devices.

However, if 'authentication timer reauthenticate server' is in place then no timer will be set unless sent from ISE. The timer can be statically configured on the switch port, or it can be dynamically assigned by sending the Session-Timeout attribute (Attribute 27) and the RADIUS Termination-Action attribute (Attribute 29) with a value of RADIUS-Request in the Access-Accept message from the RADIUS server. The reauthentication timer for MAB is the same as for IEEE 802.1X. Cisco Identity Services Engi...
