Еще раз повторюсь свитч и dhcp в одном влане, клиенты в другом. С 3200 серией в этом же месте где стоит свитч -
ПРОБЛЕМ НЕТ!!!При такой конфигурации на DHCP вообще ничего не прилетает:
Код:
DGS-3120-24SC:admin#show dhcp_relay
Command: show dhcp_relay
DHCP/BOOTP Relay Status : Enabled
DHCP/BOOTP Hops Count Limit : 4
DHCP/BOOTP Relay Time Threshold : 0
DHCP Vendor Class Identifier Option 60 State: Disabled
DHCP Client Identifier Option 61 State: Disabled
DHCP Relay Agent Information Option 82 State : Enabled
DHCP Relay Agent Information Option 82 Check : Disabled
DHCP Relay Agent Information Option 82 Policy : Replace
DHCP Relay Agent Information Option 82 Remote ID : default
DHCP Relay Agent Information Option 82 Circuit ID : default

При такой прилетает, но dhcp дает отлуп и dhcp snooping блочит абонента:
