VLTi using 10GbaseT connections
Hi,
we have two Dell S4128T-ON running OS version 10.3.1E. the switches are uplinked to Dell VRTX chassis,via two uplinks from a 40G QSFP to 4x 10G DAC Cable.
as of now the connectivity is shown in the diagram Actual Topology, as you can See there's a Clear Loop and Spanning Tree kicks in and blocks redundant links, which is normal.
the Issue if one of the switches go down, the ESXi host and Guests are not reachable from other networks. while opening a ticket with Dell Support they confirmed that convergence will not happen because ports are still showing as blocked.
to resolve the issue i want to configure Dell TOR switches in VLT, the problem is we do not have any spare Fiber connectivity on that Switch, and besides we are using DAC Cables we cannot use that Cable for VLTi.
my other Option is to use the 10GBaseT as VLTi and in this way we will be able to configure Port-channel on VTRX uplinks and Core switch Uplinks.
i configured VLT before on C9000 Series but using 10GbE DAC Cables.
can we use the exsting copper cables for VLTi? are there any limitations if we use them in terms of functionalilty and Performance?

Hi,
You should be able to use copper for it. Page 1617 https://dell.to/3kDVmIg says that they need to be the same media type, so if both are copper that should work. Let us know if you have any additional questions.

Hi,
In this scenario, Can I use 4 port 10Gbase-T in VLT?

Hi, I would expect you can use any of the 28 ports of 10Gbase-T for your VLT configuration, as long as they are not already used for other purposes. I believe the media type for the VLTi should be the same, so if you’re using copper for the rest of your connections, you can use copper for the VLTi as well. I didn't encounter there should be no limitations in terms of functionality and performance when using copper cables for VLTi.
