Port Mapping for SteelHead SD
This appendix summarizes the port mapping for SteelHead SD appliances. It includes these sections:
SteelHead SD 570-SD and 770-SD appliances
Physical ports
The SteelHead SD 570-SD and 770-SD appliances have these ports:
•AUX, PRI, LAN0_0, WAN0_0, LAN0_1, WAN0_1
CVM ports
The CVM has these ports:
•knet2, knet3, knet4, knet5, knet6, knet7
Physical port to flows port mapping
Physical port | AUX | Primary | LAN0_0 | WAN0_0 | LAN0_1 | WAN0_1 |
Flows port | 8 | 9 | 10 | 11 | 12 | 13 |
Service chain virtual machines
Virtual machine (VM) | Pod name | Function |
Service virtual machine (SVM) | catfish_secure_node0 | Overlay tunnels, QoS, NAT, etc. |
Routing virtual machine (RVM) | routing_pod0 | Routing protocols, DNS service |
Virtual SteelHead (vSH) | vsh_node0 | 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
Node name | Interface name | Port |
cvm | knet2 | AUX |
cvm | knet3 | PRI |
cvm | knet4 | LAN0_0 |
cvm | knet5 | WAN0_0 |
cvm | knet6 | LAN0_1 |
cvm | knet7 | WAN0_1 |
catfish_secure_node0 | knet22 | WAN0_1 |
catfish_secure_node0 | knet23 | WAN0_0 |
catfish_secure_node0 | knet24.1101 | LAN0_0 |
catfish_secure_node0 | knet24.1100 | LAN0_0 |
catfish_secure_node0 | knet25 | LAN0_1 |
catfish_secure_node0 | knet26 | — (binds to vSHLAN0_0) |
catfish_secure_node0 | knet27 | — (binds to vSH WAN0_0) |
routing_pod0 | knet18 | LAN0_1 |
routing_pod0 | knet19.1101 | LAN0_0 |
routing_pod0 | knet19.1100 | LAN0_0 |
routing_pod0 | knet20 | WAN0_1 |
routing_pod0 | knet21 | WAN0_0 |
vsh_node0 | knet14 | PRI |
vsh_node0 | knet15 | AUX |
vsh_node0 | knet16 | LAN0_0 |
vsh_node0 | knet17 | WAN0_0 |
Bridged VM ports for internal communication
Source | Port name | IP address | Protocol | Remote end | Purpose |
CVM | port1 | 169.254.0.2 | Static | Hypervisor mgmt_br bridge | Connects to hypervisor |
port2 | 169.254.169.254 | Static | Hypervisor linklocal_br bridge | Connects to service chain VMs |
SVM | port1 | —* | Static* | Hypervisor linklocal_br bridge | Connects to CVM |
RVM | port1 | —* | Static* | Hypervisor linklocal_br bridge | Connects to CVM |
vSH | hpn | —* | DHCP | Hypervisor linklocal_br bridge | Connects to CVM |
* Allocated at runtime.
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
Physical port to flows port mapping
Physical port | AUX | Primary | LAN3_0 | WAN3_0 | LAN3_1 | WAN3_1 |
Flows port | 8 | 9 | 10 | 11 | 12 | 13 |
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.
