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.
Oct 13 16:50:09 DHCPR: dhcp option 82: dhcp request in process...
Oct 13 16:50:09 DHCPR: llid_packetsave: 0.0.0.0 <-- 89.c9.71.1b
Oct 13 16:50:09 DHCPR: llid_packetsave=0x89c9711b
Oct 13 16:50:09 DHCPR: dhcpr_snooping_option82_request line=1365, EPON_DIID_GET failed, LLID port=0x89c9711b
Oct 13 16:50:09 DHCPR: packet length is 415(87c0fefc).
Oct 13 16:50:09 DHCPR: dhcpr to l2: diid=5,vlanid=13
Oct 13 16:50:09 DHCPR: update xid(3aef48f6) pkt config.
Oct 13 16:50:09 DHCPR: packet is for Layer2 forward and submit to Layer3
Oct 13 16:50:09 DHCPR: send packet continue
olt-test#sh ip dhcp-relay snooping
ip dhcp-relay snooping
ip dhcp-relay snooping vlan 2,50
ip arp inspection vlan 2,13,50
ip verify source vlan 2,13,50
DHCP Snooping trust interface:
GigaEthernet0/3
GigaEthernet0/1
diID: 5, насколько я понимаю, это GigaEthernet0/1 (у него ifIndex = 5), т.к. GigaEthernet0/5 у меня отключен:
olt-test#sh interface gigaEthernet 0/5
GigaEthernet0/5 is administratively down, line protocol is down
Ifindex is 1, unique port number is 5
