Cisco Bug: CSCte08161 - cannot get IP address from server if key-management is "wpa optional"
Jun 30, 2016
- Cisco Aironet 3700 Series
Known Affected Releases
Symptom: Wireless client does not get the IP address from dhcp server since AP does not forward the dhcp offer packet to the client if key-management is "wpa optional". We can see 802.1x succeeds, then dhcp offer is in ethernet side. This problem happens when dhcp offer is a broadcast packet. If dhcp offer is an unicast packet, this problem does not happen. 12.4(10b)JDA does not cause this problem. /config highlight/ dot11 ssid tsunami authentication open eap eap_methods authentication network-eap eap_methods authentication key-management wpa optional ! interface Dot11Radio0 encryption mode ciphers tkip wep128 Condition: Reproducibility : Yes Condition : key-management is "wpa optional" dhcp offer is broadcast packet Components: Software: 12.4(21a)JA1
