OS10 dhcp relay option 82
Hello!
I little confused with option 82 relay trough S5224F OS10 switch. I have N3200 stacked switches on access level where directly connected to VLT paired S5224F switches. IP helper for the clients vlan is enabled on OS10 switches. N3200 configured for use option 82.
I expect to see the CircuitID and RemoteID values from the N3200 switch in the DHCPDISCOVER packet. But instead, the S5224F changes the values in option 82 in the DHCP packet to its downlink port.
In OS9 was present "ip dhcp relay trust-downstream" option which where no rewrite option 82 values received from prevous-hop router. But in OS 10 this command was removed.
I need help to configure my switches for relay original option 82 values from client-face port on access switch.
