Which Comware configuration correctly configures a trunk allowing only VLANs 30 and 31, along with the untagged VLAN, based on the following output?

  • interface g1/0/23 ^ port trunk permit vlan 30 31
  • interface g1/0/23 ^ undo port trunk permit vlan 100 101 ^ port trunk permit vlan 30 31
  • vlan 100-101 ^ undo permit interface g1/0/23 ^ vlan 30-31 ^ permit interface g1/023
  • vlan 30-31 ^ permit interface g1/0/23
