C9800 on ESX 5.7 and VDS

as00001111 — Mon, 05 Jul 2021 19:02:08 GMT

Hi all!
I'm trying to deploy a C9800 WLC on an ESX server version 5.7.

Furthermore I'm using Virtual Distributed Switch on esx because it's not a standalone esx. I'm not using standalone vswitches.

I deployed the ova file and got a wlc with 3 Interfaces.

Interface 1 is OOB Mmgt. It's a routed interface. That is working fine.

Interface 2 is a trunk interface. Furthermore I got a SVI.

Problem is I cannot ping this SVI and I cannot ping from the wlc to other machines.

on esx, my vswitch portgroup is set to trunking mode.

Have you had that problem before?

Can you ping your SVI address or is it just for capwap?

Thank you in advance!

I ran into this a coupe of days ago.

VSwitch Promiscuous Mode

By default, a hypervisor vswitch is configured to Reject promiscuous mode. If C9800 is using tagged traffic (e.g. management VLAN, AP VLAN, etc.) via management port, promiscuous mode allows the vSwitch to carry tagged traffic. Therefore configure to ‘accept promiscuous mode for the vswitch.

I enabled Promiscuous Mode but that didn't help.

Are you able to ping the SVI?

I can ping all of the SVIs on the controller.

Also, make sure that there is just one default route and it's pointed to the gateway for one of the SVIs rather than the access port / OOB port.

ip route 0.0.0.0 0.0.0.0 <SVI Gateway IP>

Also, you try to ping the SVI from it's L3 gateway device to see if there is a routing problem?

You mean ESXi 6.7 not 5.7 because minimum requirement is 6.0.
