PREPARING THE SETUP PREPARING THE SETUP Connecting a PC for configuration Overview The XS is configured using a PC with a web browser. No additional software is required. Online help : For most pages of the administration server an help page is available by clicking located at the top right of the page.
PREPARING THE SETUP First configuration Step 1 : Create or modify the PC TCP/IP connection Assign to the PC an IP address different but consistent with the factory IP address of the XS. For the first configuration, assign for instance 192.168.0.1 to the PC. Step 2 : Connect the PC to the XS Connect the PC directly to the XS with any Ethernet cable (straight or cross-wired);...
PREPARING THE SETUP Temporary return to the factory settings If the IP address of the XS could not be founded, or if it is impossible to access the administration server, for example, following a bad VLAN configuration, it is possible to restore the factory settings without losing the current configuration.
PREPARING THE SETUP Configuration steps To configure the product, we advise to proceed as follows : Set up the LAN interface • Set up the SHDSL connections • Set up the RSTP or failsafe ring redundancy protocol • Set up VLAN •...
SETUP SETUP IP addresses setting • In the menu, choose Setup > IP protocol and routing > IP Protocol • Configure LAN ports network parameters : Administration IP address This is the IP address assigned to the Ethernet interface of the XS on the local network. This is the IP address of the administration server and the serial gateways.
Page 12
SETUP Use a different address for the serial gateways By default, the IP address of the serial gateways is the IP address of the administration server of the XS. It may be necessary to set a different IP address for the serial gateways especially when VLAN is enabled; in this case, this box must be checked and an IP address and a subnet mask must be entered.
SETUP SHDSL connection set up overview Principle of operation When two XS switches are connected by a twisted pair, one switch initiates the connection while the other responds and adapts automatically its data rate. The switch that initiates the connection is called STU-C. The switch that responds and adapts is called STU-R.
SETUP Connection profiles A connection profile includes all the technical parameters of an SHDSL connection. To make the connection process as simple as possible, five profiles are available. To set an SHDSL connection, one of these profiles has to be assigned to each SHDSL port. STU-R, Auto This profile has to be assigned to an SHDSL port when it has to wait for the connection (see the drawing above).
SETUP Setting up a link using one twisted pair This section describes the implementation of a point to point link on a twisted pair. Either between two XS as in the diagram below. STU-R STU-C 1 twisted pair Or between two XS in case of a daisy chain or a ring network, as in the diagram below. Port 1 Port 1 STU-C...
SETUP Set up steps Step 1 : SHDSL connection set up Assign the STU-R, Auto profile to the SHDSL port of the first XS. Assign a connection profile to the other XS (STU-C, Standard STU-C, Endurance STU-C, Performance). Step 2 : SHDSL test and set up adjustment Step 1 : SHDSL connection setup Setting up the first XS :...
Page 17
SETUP Setting up the other XS : • In the menu, choose Setup > Ethernet & switching > SHDSL ports. • Tick the Enable SHDSL1 (or 2 or 3 or 4 depending on the case) checkbox. • Assign the STU-C, Standard STU-C Performance STU-C Endurance profile.
SETUP Step 2 : SHDSL test and set up adjustment • Connect the XS to the twisted pairs. The wires of the same twisted pair can be reversed. • Power on the XS. • The connection takes about 45 s to establish with the « standard » profile and may takes a longer time with other profiles.
Page 19
SETUP • Check the quality of each SHDSL port. The SNR ratio margin must be at least 2/4. The number of erroneous seconds during the last hour must be close to 0. The number of link losses during the last 24 hours must be 0 or a few ones. •...
SETUP Setting up a link using 2, 3 or 4 twisted pairs This chapter describes how to set up a multiplexed point to point connection. A multiplexed connection is a link between two XS that uses two or three or four twisted pairs to multiply the total throughput.
SETUP Advanced setting up of an SHDSL link In special cases, it may be useful to change any of the existing connection profiles, for example, to change the SNR ratio margin or to force the modulation. The modified profile is added to the five profiles. To add a new connection profile, •...
Page 22
SETUP General settings: Automatically select STU-R/C If this checkbox is checked, the XS alternately tries to connect in STU-C and STU-R mode. Thus the connection can be established regardless the mode selected on the remote switch. Connection mode Possible values : STU-C : The XS initiates the connection and negotiates the conditions.
Page 23
SETUP Minimum bit rate Minimum rate value for this connection Possible values : 192 to 5696 kb/s step 64 Kb/s Maximum bit rate Maximum rate value for this connection Possible values : 192 to 5696 kb/s step 64 Kb/s Used margins The SNR ratio margin may be determined either according to current conditions (CC) or according to predefined conditions considered the worst (WC) Possible values :...
Page 24
SETUP Enable rates greater than 5696 kbps Leave this box unchecked if you know that the distance of the line does not allow a connection at higher data rates. Thus the range of tested rates will be narrower and the result will be more accurate or the connection setup time faster.
Page 25
SETUP Enable Auto Renegociation The SHDSL connection is established based on the line conditions at the connection time. For example, a noise can exist on the cable at this time and disappear thereafter. By default, the XS does not renegotiate its connection again, the SNR ratio margin will be higher than expected.
SETUP RSTP Overview RSTP, standing for "Rapid Spanning Tree Protocol" is specified by the IEEE in the 802.1D-2004 document. Loops in Ethernet networks are highly unwelcome, as they can cause broadcast storms, eating up all the available bandwidth and causing network outage. But sometimes they are necessary, in order to have backup paths in case a device or a link fails.
SETUP Set up • In the menu, choose Setup > Ethernet & switching > RSTP – Fail safe ring. • Select the RTSP mode. The page is divided in two parts : The general parameters. • The Ethernet & SHDSL ports parameters. •...
Page 28
SETUP Forward delay When a port changes state following a topology change, it goes through 3 states : • Blocked : All ingress traffic is discarded but BPDU frames (necessary for STP function) • Listening/Learning : The port listens to the traffic but does not forward data. This is used to detect transient loops that can be created during the convergence.
Page 29
SETUP Per port RSTP tuning parameters : Select the port to configure in the table • Port name Select one of ports of the product (Ethernet 1 to 4 or SHDSL 1 or 2). Disable RSTP on this port Check this box when the port does not participate in RSTP. Port priority When "Port cost"...
SETUP Fail-safe ring Based on the STP algorithm, that proprietary redundancy solution makes possible to handle a ring structure up to 16 SHSDL switches. One of the switches has to be selected as the ring master ; it has a particular function : The Ring Master will block one of its ports, preventing the formation of an Ethernet loop, and leave the other in forwarding mode.
Page 31
SETUP • Select the Fail-safe ring mode. • Tick the Ring master checkbox. • Select the default blocked port. • Click Save. Other switches configuration • In the menu, choose Setup > Ethernet & switching > RSTP – Fail-safe ring. •...
SETUP Loop VPN When the SHDSL network forms a daisy chain (i.e. a linear topology), and when it is not possible to form a secure ring, the "loop VPN" function allows for network redundancy if a public WAN connection (Internet) or private (MPLS) is available at each end of the SHDSL network.
Page 33
SETUP Local WAN IP address This is the IP address assigned to the LAN1 port of the XS in the IP subnet of the WAN access router. This subnet is different from the one on the other LAN ports. Netmask Netmask of the WAN router subnet.
SETUP VLAN Overview VLAN function The VLAN technology conform to the IEEE 802.1Q norm makes possible to transmit up to 4096 Ethernet networks over the same physical Ethernet layer. The devices belonging to the same Ethernet VLAN can exchange Ethernet frames with one another but cannot exchange frames with devices belonging to another VLAN except if a level 3 switch or an equivalent device makes possible to bridge that VLANs.
SETUP Set up Warning: Before saving the VLAN configuration, make sure you will be able to access to the administration html server through an Ethernet port or remotely through the line. One Ethernet port at least belongs to the same VLAN as the administration html server of the XS. •...
