[TIP] Cisco 9800: Baselining MAC filtering and PSK failures
TIP - Cisco 9800: Baselining MAC filtering and PSK failures MAC Filtering Failure Some times is good to leverage a quick call to solve an issue to baseline the behaviour of both correct authentication or failures. This time is an SSID with WPA2 Personal, with MAC filtering for Dynamic VLAN asignment via Cisco ISE. A field engineer called me because one RF Gun was not authenticating to the SSID. Knowing there is a MAC filtering on the SSID (for Dynamic Vlan Assignment) in addition to a PSK, I quickly checked the exclusion reason on the 9800: And also on ISE it was clear that the MAC address was not added to the allowed list : Although I didn´t used the Cisco Wireless Debug Analyzer until this was solved, this is the output for the current issue: Solution : The solution was easy, just add the MAC address to the authorized list. PSK Failure While I was adding the MAC address, the field engineer informed me, he re-entered the PSK on the RF Gun thinking that maybe that was the error ¬¬...
