Issue/Introduction
Informational:
1) Edges that are part of a collapsed cluster should exhibit below information on net-dvs -l:
propType = POLICY
com.vmware.common.port.block = false , propType = POLICY
com.vmware.port.extraConfig.vdl2.nestedTNConfig = version=1;vlan=141,label=62465;vlan=141,label=3073 , propType = POLICY
com.vmware.common.port.volatile.vlan = VLAN 0
ranges = 131 132 141 161-180
2) If the value "com.vmware.port.extraConfig.vdl2.nestedTNConfig" is not visible on "net-dvs -l" output for the edge ports, the nestedTNConfig is not pushed and tunnels will be down.
Symptoms:
TEP tunnels between NSX Edge and ESXi host remain down in a collapsed cluster.
Environment
VMware NSX-T Data Center
VMware NSX
Cause
The cause of "com.vmware.port.extraConfig.vdl2.nestedTNConfig" not being populated on a collapsed cluster is due to the value "lsp_inter_vtep_enable" being set to false:
GET https://<<nsx-mgr-ip>>/api/v1/edge-tuning-configuration
{
"lsp_inter_vtep_enable" : false, ----------------> its false here
"resource_type" : "EdgeTuningParameters",
"id" : "8bbc3064-xxxx-xxxx-xxxx-2d7fdc4909b0",
"display_name" : "8bbc3064-7165-46ff-b086-2d7fdc4909b0",
"_create_time" : 1663735327326,
"_create_user" : "system",
"_last_modified_time" : 1670735315890,
"_last_modified_user" : "admin",
"_system_owned" : false,
"_protection" : "NOT_PROTECTED",
"_revision" : 1
Resolution
Need to set the value "lsp_inter_vtep_enable" to true using API
Workaround:
PUT https://<<nsx-mgr-ip>>/api/v1/edge-tuning-configuration
{
"lsp_inter_vtep_enable": true,
"resource_type": "EdgeTuningParameters",
"_revision": 1
}
Additional Information
Impact/Risks:
Tunnels will remain down between Edges and ESXi hosts until this is corrected.
