А как перейти в режим "не по умолчанию"?
+ он все-равно что-то snoop'ит, даже если на порту trust
Приведу пример:
Oct 13 16:50:09 DHCPR: receive l2 packet from vlan 13, diID: 5
Oct 13 16:50:09 DHCPR: find an old xid configuration(xid 3aef48f6).
Oct 13 16:50:09 DHCPR: DHCP packet len 369
Oct 13 16:50:09 DHCPR: dhcpr_snooping_process DHCP request---pktlen=369, vlanid=13, diID=5
Oct 13 16:50:09 DHCPR: DHCP Request msg type is 1
Oct 13 16:50:09 DHCPR: dhcpr_snooping_option82_request:get pkt from interface 5 vlan 13
Oct 13 16:50:09 DHCPR: the packet has been recorded and xid is 3aef48f6.
