Existing products 15 • Up to four BES200 Series switches can be connected together using stacking ports and accessed through a single Web user interface screen. BOOTP is invoked at startup to obtain an IP address for the management interface as the switches are not equipped with a host DHCP client.
Getting started Model number Order code Description BAP120 NT5S40CAE6 802.
Existing products 17 Accessories Description Mobile USB Headset Adaptor for IP soft phones For soft clients IP Phone Key Expansion Module For 2000 series telephones Business Element Manager The Business Element Manager is a Windows application that integrates a Windows-like navigation panel with a simple network management protocol (SNMP)-based discovery mechanism and various means of product configuration depending on what features are supported by the target product.
Getting started Business Secure Router 222 (BSR222) The BSR222 is a two-port router with a Cat5 wide area network (WAN) connection and four 10/100 Mb/s LAN ports. It has roughly one-fourth the footprint of a BCM50 and is powered by a local power adaptor through a barrel plug. The router provides WAN connectivity to one or more Ethernet switches and to the necessary client and branch tunnels to enable secure remote access.
IP addressing for SMB devices and DHCP 19 All reference topologies assume that each device on the subnet has its SNMP client enabled. IP addressing for SMB devices and DHCP Nortel recommends using DHCP to obtain IP addresses for SMB devices and end nodes (such as PCs and IP phones). The SMB reference topologies 2 and 3 rely on a DHCP server running on the BSR222 in the subnet (typically occupying address 192.168.1.1). SMB reference topology 1 relies on a DHCP server running on a third-party router.
Getting started Device type Default IP address IP address range DHCP/BOOTP Notes BCM 4.0 192.168.1.2 None DHCP client enabled Only one BCM50 rec ommended in an SMB network. BES50 192.168.1.12 8 None DHCP client enabled Also suppo rts BOOTP and static IP addressing. BES100/2 00 192.168.1.13 2 BES1000 192.168.1.13 2 192.168.1.1 32 through 192.168.1.

Converged small site (mixed-vendor environment): reference topology 1 The converged small site (mixed-vendor environment)—reference topology 1 consists of a third-party router providing routing capabilities with one or more Business Ethernet Switches. Each Business Ethernet Switch (BES) provides traditional and Power over Ethernet (PoE) port-expansion capabilities to accommodate up to 48 node devices.
Converged small site (mixed-vendor environment): reference topology 1 from the private SMB subnets using access control list (ACL) rules that are configured on the third-party router. A dedicated VLAN 2 for Guest Access traffic is mapped to a dedicated service set identifier (SSID) on the BAP120. The result is a high-performance Internet-access courtesy service for individuals visiting SMB-configured sites that is secure and completely isolated from mission-critical SMB private networks.
Configuring a converged small site (mixed-vendor environment) • 25 "Installation and configuration workflow for a converged small site (mixed-vendor environment)" (page 26) The installation sequence is a critical component of this minimal configuration scenario. Nortel recommends that you wait a few minutes between configuring and installing each device to allow each device to complete the boot cycle.

Autodiscovering and configuring SMB devices to support the converged small site (mixed vendor environment) (topology 1) 27 Autodiscovering and configuring SMB devices to support the converged small site (mixed vendor environment) (topology 1) This reference topology uses the DHCP server on the third-party router to serve IP addresses to the BES100/200, BCM50, and BAP120 devices as they are connected. The IP phones receive their IP address from the BCM50 server set to IP phones only.
Converged small site (mixed-vendor environment): reference topology 1 In this example, two port-based VLANs are established on the BES100/200. VLAN 1 is the default VLAN with a port membership of 1 through 10 and 12 through 50, leaving port 11 out of the VLAN. VLAN 2 is also a port-based VLAN with port membership of 1, 2, and 11. VLAN 2 allows ports 1 and 2 to be members of the guest and default management VLANs, but keeps port 11 separated as a wired port dedicated to the guest VLAN only.

Maintenance Security settings This section details the following guidelines for improving the security on your network: • "Key factory security defaults" (page 61) • "Securing your SMB network" (page 62) Key factory security defaults The following tables list the key factory security defaults for each device. These defaults are intended to bring consistency to the SMB portfolio by allowing a near-zero configuration upon network deployment.
Maintenance The Element Manager uses the default SNMP read/write community strings as listed in the following table to discover devices. Because the SMB devices and the Element Manager are using the same values, discovery occurs upon network deployment.
Securing your SMB network 63 The Element Manager is available as an SNMP-based network management tool in the following cases: • Discovery of SNMP-based SMB data devices (BSR222, BES, BAP120) is completed using SNMP. • Validation and addition of SNMP-based SMB data devices (BSR222, BES, BAP120) on the network element tree is completed using SNMP. • Configuration of a BES device using the connect feature of the Element Manager is completed using SNMP.
Maintenance 5 Use your Web browser bookmark feature to save a shortcut to each device. 6 Use the BSR222 Web UI to note all the IP addresses that have been provided to your SMB network as follows: a. From the Web UI navigation panel located in the left-hand pane, click Maintenance. b. Click the DHCP Table tab. A listing of all IP addresses that the DHCP server allocated appears. You can access all SMB devices through a Web browser using the IP addresses obtained from the previous step.
BAP120 engineering rules and guidelines 65 The BAP120 tries unsuccessfully to obtain an IP address from the DHCP server on the BSR222. After 60 seconds, it defaults to an IP address of 192.168.1.136. —End— If you have more than one BES or BAP120 in your SMB network, IP addresses must be manually configured according to the ranges specified in the "IP addressing for SMB devices and DHCP" (page 19) table.
