2. - SBC physical and network interfaces
Oracle SBCs have dedicated interfaces to be used for signaling and media, those interfaces are defined as sXpX when listing the interfaces. As defined in the first entry two interfaces will be created and configured dedicating one for internal (s0p0) communication and the other for external (s1p1) communication.
The first step is set up a physical interface: s1p1 (slot 1 port 1)
PCOSBC# config t
PCOSBC(configure)# system phy-interface
PCOSBC(phy-interface)# name Internal
PCOSBC(phy-interface)# operation-type Media
PCOSBC(phy-interface)# port 1
PCOSBC(phy-interface)# slot 1
PCOSBC(phy-interface)#
PCOSBC(phy-interface)# done
phy-interface
name Internal
operation-type Media
port 1
slot 1
virtual-mac
admin-state enabled
auto-negotiation enabled
duplex-mode FULL
speed 100
wancom-health-score 50
overload-protection disabled
With the physical interface created an IP address can be assigned to the physical interface, the link between the physical and the network interface is using the same name, in this case Internal.
PCOSBC(system)#
PCOSBC(system)# network-interface
PCOSBC(network-interface)#
PCOSBC(network-interface)# name Internal
PCOSBC(network-interface)# ip-address 192.168.10.101
PCOSBC(network-interface)# netmask 255.255.255.0
PCOSBC(network-interface)# gateway 192.168.10.1
PCOSBC(network-interface)# add-hip-ip 192.168.10.101
PCOSBC(network-interface)# add-icmp-ip 192.168.10.101
PCOSBC(network-interface)#
PCOSBC(network-interface)# done

Now lets set up the physical interface s0p0, it will be named as External.
PCOSBC(network-interface)#
PCOSBC(network-interface)# exit
PCOSBC(system)# phy-interface
PCOSBC(phy-interface)# name External
PCOSBC(phy-interface)# operation-type Media
PCOSBC(phy-interface)# port 0
PCOSBC(phy-interface)# slot 0
PCOSBC(phy-interface)#
PCOSBC(phy-interface)# done

operation-type Media
port 0
slot 0
virtual-mac
admin-state enabled
auto-negotiation enabled

and now the network-interface for external
PCOSBC(phy-interface)# exit
PCOSBC(system)# network-interface
PCOSBC(network-interface)# name External
PCOSBC(network-interface)# ip-address 192.168.10.201
PCOSBC(network-interface)# netmask 255.255.255.0
PCOSBC(network-interface)# gateway 192.168.10.1
PCOSBC(network-interface)# add-hip-ip 192.168.10.1

With all IP addresses assigned, connectivity can be verified with show arp (this command lets you know the status connectivity to the default gateways)
In this configuration we're using 1 gateway only.
PCOSBC# show arp
