Negli host ESX, eseguire i passaggi seguenti per risolvere i problemi relativi al percorso dati del firewall distribuito (DFW) NSX. Per informazioni relative ad altri comandi per la risoluzione dei problemi del firewall, vedere NSX-T Data Center Command-Line Interface Reference.
Recuperare l'elenco delle macchine virtuali nell'host ESXi e il nome del filtro associato
In questo elenco sono riportate tutte le macchine virtuali nell'host ESXi. Annotare il valore del campo "name" e utilizzarlo nei comandi successivi per ottenere l'output pertinente per una determinata macchina virtuale.

Le regole DFW L2 mostrano un indirizzo MAC sconosciuto
Dopo aver configurato una regola del firewall di livello 2 con un set di MAC come origine e un altro set di MAC come destinazione, il comando getrules nell'host mostra il MAC di destinazione come 01:00:00:00:00/01:00:00:00:00:00. Ad esempio,
[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;
}
La regola OUT interna con indirizzo 01:00:00:00:00:00/01:00:00:00:00:00 viene creata per impostazione predefinita per gestire i pacchetti di trasmissione in uscita e non segnala un problema. La regola del firewall funzionerà come configurata.
