i've configured port security on a Catalyst 3750 inluding 12.2(40)SE as followed:
mac access-list extended PermitMAC
permit host xxxx.xxxx.xxxx any
switchport access vlan 11
switchport mode access
mac access-group PermitMAC in
If i connect a notebook with the MAC-address yyyy.yyyy.yyyy to the interface Gi1/0/1, the notebook
gets a IP-address from the DHCP-Server which is located in the same segment as interface Gi1/0/1.
My expectation was:
The client shouldn't get any IP-Adress because the DHCP request from the client contains the MAC source
address which doesn't match the allowed list "PermitMAC".
Does anyone knows why the client even gets a IP-Address from the DHCP Server ?
Thank you very much in advance and
