    <description>&lt;P&gt;Hi All,&lt;/P&gt;&lt;P&gt;I'm facing the issue of not being able to achieve 1 Gbps transmission speed in the network.&lt;/P&gt;&lt;P&gt;This is my network setup, its s &lt;STRONG&gt;Partially Nested Setup&lt;/STRONG&gt; (&lt;STRONG&gt;I'm aware its not supported by VMware, &lt;/STRONG&gt;this is in a home lab).&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Dell.png" style="width: 999px;"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/91429iD38B6A470648D290/image-size/large/is-moderation-mode/true?v=v2&amp;amp;px=999" role="button" title="Dell.png" alt="Dell.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;The physical disks are 7200 RPM HDD &lt;STRONG&gt;1TB&lt;/STRONG&gt;, NIC ports on Dell and the Physical Switch are all 1 Gbps, the LAN cable is CAT5e, only the Laptop interface is &lt;STRONG&gt;100 Mbps&lt;/STRONG&gt;.&amp;nbsp;I also checked the switch interfaces, it has auto detect feature and shows all ports as 1000Mbps except the laptop port which 100Mbps.&lt;/P&gt;&lt;P&gt;The vCenter is running in VMware Workstation and has the Nested ESXi added to its SDDC.&lt;/P&gt;&lt;P&gt;I'm backing up VM running in the Nested ESXi (stored in the StarWind NAS &amp;amp; SAN) to Veeam Server storage and the issue is that Backup speed never goes above 6Mbps, 1 Gbps throughput should give at the very least ~75 to ~90 Mbps.&lt;/P&gt;&lt;P&gt;I ran iPerf between the Veeam Server and the VM running on the Nested ESXi, the throughput still turned out to be 100Mbps and not 1 Gbps.&lt;/P&gt;&lt;LI-SPOILER&gt;PS C:\Users\Administrator.VLAB\Desktop\iperf-3.1.3-win64&amp;gt; ./iperf3.exe -c 10.10.60.68&lt;BR /&gt;Connecting to host 10.10.60.68, port 5201&lt;BR /&gt;[ 4] local 10.10.20.6 port 57241 connected to 10.10.60.68 port 5201&lt;BR /&gt;[ ID] Interval Transfer Bandwidth&lt;BR /&gt;[ 4] 0.00-1.01 sec 11.4 MBytes 94.5 Mbits/sec&lt;BR /&gt;[ 4] 1.01-2.01 sec 14.6 MBytes 123 Mbits/sec&lt;BR /&gt;[ 4] 2.01-3.00 sec 13.1 MBytes 111 Mbits/sec&lt;BR /&gt;[ 4] 3.00-4.01 sec 11.8 MBytes 98.2 Mbits/sec&lt;BR /&gt;[ 4] 4.01-5.00 sec 11.0 MBytes 92.8 Mbits/sec&lt;BR /&gt;[ 4] 5.00-6.00 sec 11.1 MBytes 92.9 Mbits/sec&lt;BR /&gt;[ 4] 6.00-7.01 sec 11.0 MBytes 92.2 Mbits/sec&lt;BR /&gt;[ 4] 7.01-8.01 sec 10.9 MBytes 90.6 Mbits/sec&lt;BR /&gt;[ 4] 8.01-9.01 sec 10.0 MBytes 83.7 Mbits/sec&lt;BR /&gt;[ 4] 9.01-10.01 sec 10.4 MBytes 87.8 Mbits/sec&lt;BR /&gt;- - - - - - - - - - - - - - - - - - - - - - - - -&lt;BR /&gt;[ ID] Interval Transfer Bandwidth&lt;BR /&gt;[ 4] 0.00-10.01 sec 115 MBytes 96.6 Mbits/sec sender&lt;BR /&gt;[ 4] 0.00-10.01 sec 115 MBytes 96.5 Mbits/sec receiver&lt;/LI-SPOILER&gt;&lt;P&gt;I ran tcpdump on the laptop interface (100Mbps) interface just to see if any traffic traverses it during iPerf test, but there was no traffic.&lt;/P&gt;&lt;P&gt;At this point I'm not sure what is causing the traffic to traverse at 100 Mbps, any thoughts ?&lt;/P&gt;&lt;P&gt;Thank You&lt;/P&gt;</description>

      <description>&lt;P&gt;So I pull all cables out of the Server, Switch and replugged them and now I'm getting&lt;/P&gt;&lt;LI-SPOILER&gt;[ 4] local 10.10.20.5 port 59278 connected to 10.10.20.6 port 5201&lt;BR /&gt;[ ID] Interval Transfer Bandwidth&lt;BR /&gt;[ 4] 0.00-1.01 sec 14.8 MBytes 123 Mbits/sec&lt;BR /&gt;[ 4] 1.01-2.00 sec 24.4 MBytes 205 Mbits/sec&lt;BR /&gt;[ 4] 2.00-3.00 sec 24.2 MBytes 204 Mbits/sec&lt;BR /&gt;[ 4] 3.00-4.00 sec 24.2 MBytes 203 Mbits/sec&lt;BR /&gt;[ 4] 4.00-5.00 sec 24.2 MBytes 204 Mbits/sec&lt;BR /&gt;[ 4] 5.00-6.00 sec 24.2 MBytes 203 Mbits/sec&lt;BR /&gt;[ 4] 6.00-7.01 sec 24.4 MBytes 204 Mbits/sec&lt;BR /&gt;[ 4] 7.01-8.00 sec 24.2 MBytes 205 Mbits/sec&lt;BR /&gt;[ 4] 8.00-9.00 sec 24.4 MBytes 204 Mbits/sec&lt;BR /&gt;[ 4] 9.00-10.00 sec 24.1 MBytes 203 Mbits/sec&lt;BR /&gt;- - - - - - - - - - - - - - - - - - - - - - - - -&lt;BR /&gt;[ ID] Interval Transfer Bandwidth&lt;BR /&gt;[ 4] 0.00-10.00 sec 233 MBytes 196 Mbits/sec sender&lt;BR /&gt;[ 4] 0.00-10.00 sec 233 MBytes 196 Mbits/sec receiver&lt;/LI-SPOILER&gt;&lt;P&gt;So not sure if the cables are the issue, or is the Server, Switch renegotiating, Veeam back up speed also went up to 8 MBps..&lt;/P&gt;</description>
