WAN optimization
SteelHead SD dynamically allocates vSwitch ports based on service chain configuration and the WAN optimization toggle.
vSwitch mapped VM ports
The vSwitch port mapping state can be fetched at runtime using this command on the CVM:
XNXXXXD8XXXA9FF9-CVM:>orchestrator-agent --get_port_interface_mapping

SteelHead SD 3070-SD appliance
Physical ports
The SteelHead SD 3070-SD appliance has these physical ports:
AUX, PRI, LAN3_0, LAN3_0, WAN3_1, WAN3_1
These ports are present only if you have installed an add-on NIC:
LAN2_0, WAN2_0, LAN2_1, WAN2_1
CVM ports
The CVM has these ports:
knet2, knet3, knet4, knet5, knet6, knet7
These ports are present only if you have installed an add-on NIC:
knet8, knet9, knet10, knet11

The 3070-SD appliance supports add-on NICs. The presence of an add-on NIC can change the total NIC count on the appliance and can also result in different flows port mapping accordingly. Each add-on NIC can carry either two or four NICs. For details on add-on NICs, see NIC support.
SVM ports
There are four more virtual NICs in SVM for each physical add-on NIC.
RVM ports
There are four more virtual NICs in RVM for each physical add-on NIC.
vSH ports
The vSH has these ports:
hpn, PRI, AUX, LAN0_0, WAN0_0, inpath0_0
vSH has only one LAN-WAN pair and will not change with the addition of any physical add-on NIC.
