[...] > hi ben,thanks for your help,would you mind tell me "32~63" VID filter? > still can not understand the vlan-mask The vlan-mask specifies tag bits to be ignored. You want to ignore the priority, CFI and lower 5 bits of the VID, hence 0xf01f. For a different group of 32 VIDs you would only change the vlan argument, not the vlan-mask argument.
