Modifying, Enabling, and Disabling a Logical Interface

The example below is shown for SBC 2000.

  1. In the WebUI, click the Settings tab.

  2. In the left navigation pane, go to Node Interfaces > Logical Interfaces.

    Logical Interfaces - SBC 2000 Example

     
 

The third Ethernet port on the SBC 1000 is available only if running SBC 1000 v2 hardware. For hardware details, see Sonus SBC 1000 Hardware Specifications.

The Administrative IP port (available on the SBC 2000 only),should only be used for Running Initial Setup and disconnected when not in use (especially to avoid conflicts with your network). This interface cannot be used for VOIP media or protocols.

Note: The functionality of enabling and disabling system created logical interfaces (e.g. Ethernet 1, Ethernet 2, etc.) is available on the Sonus SBC 2000 only. Enabling and disabling VLAN logical interfaces can be done on all platforms.

To modify a Logical Interface:

  1. Click the expand () Icon next to the entry you wish to modify.
  2. Edit the entry properties as required.

To enable a Logical Interface:

  1. Select the check box next to the entry you wish to enable.
  2. Click the Enable () icon at the top of the table. 

To disable a Logical Interface:

  1. Select the check box next to the entry you wish to disable.
  2. Click the Disable ( ) icon at the top of the table. 

Configuring Logical Interfaces

Three modes of addressing are suppored for Logical Interfaces: IPv4 only, IPv6 only, and Both (includes IPv4 and IPv6). When IPv6 or Both is selected as the mode, one primary IPv6 address can be statically configured. By default, interfaces are in IPv4 mode only.

The Logical Interfaces are configured when Running Initial Setup. Once initial configuration is complete, the fields below are able to be modified.

Identification/Status - Field Definitions

Alias

Specifies an alias for the interface.

Description

Specifies a description for the interface.

Admin State

Specifies the administrative state of the port. Valid entries: Enabled or Disabled.

Networking - General Options

MAC Address

MAC address assigned to the interface; this field is automatically populated from the system.

IP Addressing Mode

Specifies the IP address mode that is assigned for that Logical Interface. Determines if the interface is IPv4, IPv6, or both. Valid entry: IPv4, IPv6 or Both. Default entry: IPv4. Depending on the mode selected, specific configuration fields are displayed; these are noted where applicable.

VLAN tag

Note: This field is for SBC SWe Lite only.

The VLAN tag is a value assigned for the sub-interface.

Networking - IPv4 Options

The following fields below are displayed when IPv4 or Both is selected from the IP Addressing Mode option.

By configuring the IP Assign Method to DHCP, the DNS server(s), NTP server(s), domain name and the default IP Route will be overwritten and configured dynamically.

Each logical interface can have a primary IP address and a secondary IP address. The secondary IP address is useful for WebUI or Sonus SBC Edge API User's Guide operations only, and should not be used for VOIP media or protocols such as SIP, RTP and SRTP.

ACL IN

Specifies the Access Control List to be used on this interface when filtering incoming packets. Select from the drop down list (populated from the Access Control List table). For more information about Access Control Lists, see Managing Access Control Lists.

ACL Out

Specifies the Access Control List to be used on this interface when filtering outgoing packets. Select from the drop down list (populated from the Access Control List table). For more information about Access Control Lists, see Managing Access Control Lists.

ACL Forward

Specifies the Access Control List to be used when filtering forwarded (i.e. routed) packets received on this interface. Select from the drop down list (populated from the Access Control List table). For more information about Access Control lists, see Managing Access Control Lists.


IP Assign Method

Specifies how the IP address is assigned for that interface. Select from the drop down box. Available options: Static (User configured IPv4 address, netmask and system network configuration) or DHCP (Automatically acquired IPv4 address, netmask, and other system network configuration).

Note: DHCP applies to IPv4 addresses only; IPv6 addresses must be statically configured.

If you are configuring the IP Assign method from DHCP to Static, you should add a new default static route. We recommend this be done through the Modify Ethernet IP task (this allows you to set the IP address and the default route in one step). See Modifying the Sonus SBC 1000 IP Address and Modifying the Sonus SBC 2000 IP Address.

WARNING: If you set the IP Assign method to DHCP, the DNS server(s), NTP server(s), domain name and the default IP Route will be overwritten and configured dynamically. 

Primary Address

Specifies the Primary IP Address through which the Sonus SBC 1000/2000 communicates over Ethernet, and by which the application may be accessed. This field is available only when the IP Assign Method field is set to Static.

Primary Netmask

Specifies the network mask applied to the Primary IP Address. This field is available only when the IP Assign Method field is set to Static.

Configure Secondary Interface

Specifies whether a Secondary IP address and Secondary Netmask should be configured. Available options: Enabled (enables the Secondary Address/Netmask options) or Disabled (disables the Secondary Address/Netmask options). This field is available only when the IP Assign Method field is set to Static.

Secondary Address

Specifies the Secondary IP Address through which the Sonus SBC 1000/2000 communicates over Ethernet, and by which the application may be accessed. This field is available only when the Configure Secondary Interface field is set to Enabled.

Secondary Netmask

Specifies the network mask applied to the Secondary IP Address. This field is available only when the Configure Secondary Interface field is set to Enabled.

DHCP Options to Use

Specifies the parameters supplied by the DHCP server when the logical interface is configured with Dynamic IP addressing.

Available options:

  • All – The SBC uses all supported DHCP parameters. The supplied DNS servers are used as global DNS servers and replace the ones already configured. Split DNS not affected.
  • IP Address – The SBC only uses the IP address and netmask are used. The DNS server and other settings are ignored. Split DNS not affected. 
  • IP Address and DNS – The SBC only uses the IP address, domain-name, and DNS server IP address. The supplied domain-names and the DNS server IP addresses are only used if Use as Split DNS is Enabled.

This field is available only when the IP Assign Method field is set to DHCP.

Use as Split DNS

Specifics whether a Split DNS should automatically be created using parameters supplied by the DHCP server.

Available options:

  • Enabled: Enables Split DNS to be created from each combination of domain-name and DNS server supplied by the DHCP server. When the DHCP-lease expires, the Split DNS settings are automatically removed.
  • Disabled: Disables Split DNS and uses DHCP parameters as global settings. When the DHCP-lease expires, the Split DNS settings are removed.

This field is available only when the DHCP Options to Use field is set to IP Address and DNS.

Networking - IPv6 Options

The fields below are displayed when IPv6 or Both is selected from the IP Addressing Mode option.

ACL IN

Specifies the Access Control List to be used on this interface when filtering incoming packets. Select from the drop down list (populated from the Access Control List table). For more information about Access Control Lists, see Managing Access Control Lists.

ACL Out

Specifies the Access Control List to be used on this interface when filtering outgoing packets. Select from the drop down list (populated from the Access Control List table). For more information about Access Control Lists, see Managing Access Control Lists.

ACL Forward

Specifies the Access Control List to be used when filtering forwarded (i.e. routed) packets received on this interface. Select from the drop down list (populated from the Access Control List table). For more information about Access Control lists, see Managing Access Control Lists.

Link Local Address/Link Local Prefix

Note: This field applies to IPv6 only.

The Link Local address is a system assigned and is unique to its local LAN. The system assigns this address to map IPv6 addresses to link-layer addresses.

Primary Address

Specifies the primary IPv6 address for the interface through which the SBC 1000/2000 communicates over Ethernet. Example IPv6 address: 2001:db8:10::197. Using IPv6 or Both (IPv4/IPv6) mode, only one primary IPv6 address can be statically configured.

Primary Address Prefix

Specifies the primary IPv6 network prefix length for the interface through which the SBC 1000/2000 communicates over Ethernet. Valid entry 1 - 127. Default value: 64.
