Greetings,
Did you add the third nic on your hypervisor? I added one using ESX and it showed up both in TMSH and the UI:
tmsh list net interface
net interface 1.1 {
if-index 48
mac-address 00:50:56:92:5f:50
media-fixed 10000T-FD
media-max 10000T-FD
mtu 9198
}
net interface 1.2 {
if-index 64
mac-address 00:50:56:92:5e:44
media-fixed 10000T-FD
media-max 10000T-FD
mtu 9198
}
net interface mgmt {
if-index 32
mac-address 00:50:56:92:6f:e2
media-active 100TX-FD
}
Add nic on ESX. Reboot.
tmsh list net interface
net interface 1.1 {
if-index 48
mac-address 00:50:56:92:5f:50
media-fixed 10000T-FD
media-max 10000T-FD
mtu 9198
}
net interface 1.2 {
if-index 64
mac-address 00:50:56:92:5e:44
media-fixed 10000T-FD
media-max 10000T-FD
mtu 9198
}
net interface 1.3 {
if-index 80
mac-address 00:50:56:92:4d:6b
media-fixed 10000T-FD
media-max 10000T-FD
mtu 9198
}
net interface mgmt {
if-index 32
mac-address 00:50:56:92:6f:e2
media-active 100TX-FD
}
