Cisco Bug: CSCvv49684 - DNAC NDP failing to choose right MAC for multiple ISE sessions with the same IP
Sep 03, 2020
- Cisco DNA Center
Known Affected Releases
Symptom: Hydra is not detecting spoofing because NDP nf-stream events are populated with wrong Client MAC address and as a result Hydra is not processing those flows (and not detecting the attack). Conditions: Have multiple sessions on ISE with the same IP address (and different MAC), that is causing NDP to choose the wrong session for IP-MAC bindings.
