Description
The show command for the dhcp_server does not work as expected for smartswitch platform. This is because the Port is obtained for the show command from the FDB entry in STATE_DB for the corresponding dhcp_interface, but for smartswitch the the DPUs are provided with link local addresses by the switch, and hence the port information is not present in the FDB table, due to this the port is shown as unknown in the output of the show dhcp_server ipv4 lease command. The code is present here
Steps to reproduce the issue:
- On smartswitch platform execute the
show dhcp_server ipv4 leasecommand
Describe the results you received:
admin@sonic:/tmp$ show dhcp_server ipv4 lease

The ip -n command could be used to obtain the neighbor information and this can be used to obtain the port name
