用於防火牆疑難排解的 NSX CLI

在 ESXi 上,nsxcli 選項可用作 ESX cli 的替代選項 (方法是輸入「nsxcli」),且使用者可使用「get firewall」命令樹取得類似上方的輸出。

DFW L2 規則顯示未知的 MAC 位址

設定第 2 層防火牆規則並將其中一個 MAC 設定為來源,以及將另一個 MAC 設定為目的地之後,主機上的 getrules 命令將目的地 MAC 集合顯示為 01:00:00:00:00:00/01:00:00:00:00:00。例如,
[root@host1:~] vsipioctl getrules -f nic-1000052822-eth1-vmware-sfw.2
ruleset mainrs {
  # generation number: 0
  # realization time : 2018-07-26T12:42:28
  rule 1039 at 1 inout protocol tcp from any to any port 1521 accept as oracle;
  # internal # rule 1039 at 2 inout protocol tcp from any to any port 1521 accept;
  rule 1039 at 3 inout protocol icmp from any to any accept;
  rule 2 at 4 inout protocol any from any to any accept with log;
}

ruleset mainrs_L2 {
  # generation number: 0
  # realization time : 2018-07-26T12:42:28
  rule 1040 at 1 inout ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to addrset 9ad9c6ef-c7dd-4682-833d-57097b415e41 accept;
  # internal # rule 1040 at 2 in ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to addrset 9ad9c6ef-c7dd-4682-833d-57097b415e41 accept;
  # internal # rule 1040 at 3 out ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to mac 01:00:00:00:00:00/01:00:00:00:00:00 accept;
  rule 1 at 4 inout ethertype any stateless from any to any accept;
}

The internal OUT rule with the address 01:00:00:00:00:00/01:00:00:00:00:00 is created by design to handle outbound broadcasting packets and does not indicate a problem.防火牆規則可依照設定運作。
