SBC 1000

The SBC 1000 has three Ethernet ports used for communicating with the IP network. All SIP traffic is carried on these two ports. Unlike the SBC 2000, this model has no dedicated Management Port.

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

SBC 2000

The SBC 2000 has four Ethernet ports and one Ethernet Management port. By default, each of the four non-management ports are in their own system created VLAN, and are isolated from one another.

ASM

If the unit is equipped with a built-in ASM, all ASM traffic is carried uniquely through this Ethernet port.

For communication between the SBC 1000/2000 and the ASM to work properly, the ASM port's Default Untagged VLAN must be set to a VLAN whose logical IP address is in the same subnet as the ASM's IP address. For example, if the ASM port's default VLAN is set to Ethernet 1 VLAN, then the logical interface Ethernet 1 IP must have its IP address in the same subnet as the ASM IP.

Working with Ethernet Ports:

  1. In the WebUI, click the Settings tab.

  2. In the left navigation pane, go to Node Interfaces > Ports. See below for examples.

Ethernet Redundancy for Failover

Ethernet redundancy on the SBC 1000/2000 supports continued operation of the SBC if failures occur regarding the underlying Ethernet service, such as:

  • Ethernet switch malfunction
  • Ethernet port malfunction

By offering a standby Ethernet port to an active port, the SBC 1000/2000 allows SBC traffic to be re-directed from a primary Ethernet switch to an alternate Ethernet switch (within the same subnet) that is pre-configured (by the enterprise) with the same network connections as the primary Ethernet switch. The alternate switch is assumed capable of recognizing the introduction of live traffic to/from the SBC (over the standby Ethernet port) and to recover the outbound/inbound connections to the rest of the network.

Ethernet redundancy includes:

  • A provisioning construct called Ethernet Redundancy Pair
    Only one instance of pair will be supported by the SBC 1000 at any given time;
    A maximum of two instances of pair will be supported by the SBC 2000 at any given time;
  • Any pair must be associated with two physically distinct Ethernet ports; on the SBC 2000, all Ethernet ports associated with one or two pair(s) must be unique;
  • One port within the pair is selected as primary (carries all Tx and Rx to a primary Ethernet switch); the other is provisioned as the standby and is connected to an alternate Ethernet switch in the same subnet;
  • The SBC will offer the provisioning of a single IP address to the pair, to "hide" from upper SBC application layers the Ethernet redundancy feature (i.e. only a single IP address may be assigned to the pair).


The Ethernet redundancy featuredoes not support load balancing, and does not guarantee SBC availability.


To configure Ethernet Port Redundancy, refer to the following pages for details:


To view a Ethernet Port's properties:

  1. Click the pop-up icon () next to the entry you want to view.
  2. When you are finished, close the window.

To delete an entry, select the checkbox next to the entry and then click the Delete () icon.

For the SBC 2000 only: The Ethernet Port must be enabled for continued access to the management interface. If you attempt to disable the Ethernet Port with the status of "Up", the following warning message is displayed:

You are disabling the Ethernet port(s) which are currently up. Please ensure that you are not disabling ports required for continued access to this management interface. Are you sure you want to disable all the selected ports?

To continue disabling the port, click OK. To cancel the delete, click Cancel.
