Network Button

Use the Network button to access the following configuration elements.

Host route	Specify where to direct management traffic.
Network interface	Specify a logical network interface over which you can configure one or more SIP interfaces.

Host Routes

Host routes let you insert entries into the Oracle® Enterprise Session Border Controller (E-SBC) routing table. These routes affect traffic that originates at the E-SBC host process. Host routes are used primarily for steering management traffic to the correct network.

When traffic is destined for a network that is not explicitly defined on an E-SBC, the default gateway is used. If you try to route traffic to a specific destination that is not accessible through the default gateway, you need to add a host route. Host routes can be thought of as a default gateway override.

Certain SIP configurations require that the default gateway is located on a front media interface. In this scenario, if management applications are located on a network connected to a rear-interface network, you need to add a host route for management connectivity.

When source-based routing is used, the default gateway must exist on a front media interface. Host routes might be needed to reach management applications connected to a wancom port in this kind of situation.

Add a Host Route

You can configure the Oracle® Enterprise Session Border Controller (E-SBC) to steer management traffic to the correct network by inserting an entry in the routing table.

Use the following procedure to insert an entry into the E-SBC routing table.

1. From the Main Menu, click Network, Host routes.
2. On the Host Route page, click Add.
3. In the Add Host Route dialog, do the following.

   Dest network	Enter the IPv4 address of the destination network that this host route points to. Dotted decimal format. For example, 192.30.1.104. No two host-route elements can use the same destination network address.
   Netmask	Select the netmask from the drop-down list associated with the destination network that you entered for the Dest network parameter.
   Gateway	Enter the gateway which traffic destined for the address defined in the Dest network parameter should use as its first hop when forwarding a packet out of the originator’s LAN. Dotted decimal format. For example, 192.30.1.1.
   Description	Enter a description for this host route. Valid values are alpha-numeric characters. For example, Host Route A.

4. Click OK to save the host route.
   The host route that you created displays in the Host Routes table.
5. Click Close.
6. Save the configuration.

Network Interface Configuration

The network interface element specifies a logical network interface. In order to use a network port on a network interface, you must configure both the physical interface and the corresponding network interface configuration elements.

Add a Network Interface

Use the network interface element to create and configure a logical network interface.

You can add a network interface from the Web GUI in either Basic mode or Expert mode. If the network interface does not use VLANs tagging, ensure that the subport ID field is set to 0, the default value. When VLAN tags are used on a network interface, the valid subport ID value can range from 1-4096. Network interface is a multiple instance configuration element. The combination of the name field and the subport ID field must be unique in order to identify a discrete network interface. Except where noted, you can use an IPv6 IP address in any parameter in the following procedure.

1. From the Web GUI, select Configuration, Network, Network interface.
2. In the Network interface dialog, click Add.
3. In the Add Network interface dialog, click Show advanced, and do the following:

   Name	Enter the name of the physical interface with which this network-interface element is linked. For example Enterprise. Network-interface elements that correspond to phy-interface elements with an operation type of Control or Maintenance must start with “wancom.”
   Sub port ID	Required only for a VLAN, where the operation type is Media. Enter the identification number from 1-4095 of a specific virtual interface in a physical interface. Otherwise, leave the default 0, which means this element is not using a virtual interface.
   Description	Enter a description of this interface for easier identification.
   Hostname	(Optional) Enter the hostname of this network interface in FQDN or IP Address format.
   IP Address	Enter the IP address of this network interface in IP Address format.
   Pri utility address	Enter the utility IP address for the primary High Availability (HA) peer in an HA architecture.
   Sec utility address	Enter the utility IP address for the secondary Oracle Communications Session Border Controller in an HA architecture.
   Netmask	Enter the netmask portion of the IP address for this network interface entered in IP address format.
   Gateway	Enter the gateway this network interface uses to forward packets in IP Address format.
   Sec gateway	Enter the gateway to use on the secondary Oracle® Enterprise Session Border Controller (E-SBC) in an HA pair in IP Address format.
   Gw heartbeat	Click to display the configuration fields.
   State	Select to enable the front interface link detection and polling functionality on the E-SBC.
   Heartbeat	Enter the time interval in seconds between heartbeats for the front interface gateway.
   Retry count	Enter the number of front interface gateway heartbeat retries before a gateway is considered unreachable.
   Retry timeout	Enter the heartbeat retry timeout value in seconds.
   Health score	Enter the amount to subtract from the health score if the front interface gateway heartbeat stops responding.
   DNS IP primary	Enter the IP address of the primary DNS to be used for this interface.
   DNS IP backup 1	Enter the IP address of the first backup DNS to be used for this interface.
   DNS IP backup 2	Enter the IP address of the second backup DNS to use for this interface.
   DNS domain	Set the default domain name used to populate incomplete hostnames that do not include a domain in Name format.
   DNS timeout	Enter the total time in seconds to elapse before a query (and its retransmission) is sent to a DNS server timeout.
   Signalling MTU	Enter the size of the Maximum Transmission Unit for packets leaving this interface. Default-inherits system-wide MTU. IPv4-0, 576-4096. IPv6-0, 1280-4096.
   HIP IP list	Add all IPv4 Host Identity Protocol lists for which you want the E-SBC to accept administrative traffic.
   FTP address	Enter a list of IP addresses from which FTP traffic can be received and acted upon by a front media interface.
   ICMP address	Enter the IP address to pass standard ping packets to the host.
   Telnet address	Enter the IP address where port 23 is open for Telnet access.
   SSH address	Enter a list of IP addresses from which SSH traffic can be received and acted upon by a front media interface. Requires a valid IPv4 network address.
