What are you trying to achieve using this filter? These ports are used by DHCP service. So if you see no such packets in a trace it means:
or they were not present in the network (DHCP is not in use) ; or your capture setup is not correct.
For how long did you run the capture? DHCP can be silent for some time period even when it's in use, it depends on DHCP server settings.
