Troubleshooting (Logs, Procedures and Techniques)

Configuration

HA Configuration:

Need to be configured in both nodes.

vlt domain 100
peer-link port-channel 1
back-up destination 10.11.183.29
primary-priority 1
system-mac mac-address 00:a1:a1:a1:00:00
unit-id 0
peer-routing

At each switch, the vxlan-instance must be configured to enable the vxlan feature:

Standalone:

feature vxlan
!
vxlan-instance 1
gateway-ip 50.10.2.2
controller 1 10.11.183.97 port 6640 ssl
no shutdown

HA:

feature vxlan
!
vxlan-instance 1 nsx
gateway-ip 50.10.2.2
controller 1 10.11.183.97 port 6640 ssl
peer-ovsdbserver-ip 10.11.183.29
no shutdown

In addition, use this configuration in each access port (to the physical devices):

Standalone:

interface fortyGigE 1/1
description VTEP L2 Gateway
vxlan-instance 1
no ip address
no shutdown

HA:

interface Port-channel 128
description VTEP L2 Gateway
vxlan-instance 1
no ip address
mtu 9216
switchport
vlt-peer-lag port-channel 128
no shutdown

Debug command:

debug vxlan ovsdb-json-rpc packet-type all vxlan-instance 1

Note: This helps to debug the VTEP to NSX messages.
