Hello, I have a CBS 250 switch running in L3 mode with a number of VLANs. I have configured the DHCP relay option on the switch for each VLAN to point to the upstream DHCP server (actually the router). The DHCP request/offers are getting sent/received, but when relaying them to the DHCP server the switch randomly replaces the client's MAC with the switch's own MAC. It seems unpredictable when it will do this. This behavior breaks my DHCP reservations, as the reservations are based on MAC address. How can I get the switch to stop doing this? Thanks in advance.
