    When I add dhcpv4-snooping, client on 1/1/2 cannot get a IP 
    moment I remove snooping dhcp works fine again. 

    Setup is about as simple as it gets, even did a reboot of the whole lot.  



    CX6300 Switch Layer2 ( not doing DHCP relay ) 
    Version      : FL.10.10.1130 


    vlan 1234
        name NAME_OF_VLAN
        dhcpv4-snooping
        dhcpv6-snooping


    interface lag 1
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed 1234
        lacp mode active                                           
        hash l4-src-dst
        lacp rate fast
        apply access-list ip some_acl in
        apply access-list ip some_acl out
        dhcpv4-snooping trust
        dhcpv6-snooping trust

    interface 1/1/2
