1.1 Introduction

Your S witch is a Gigabit Ethernet (GbE) switch with 20, 44 or 48 10/100/1000 Mbps Ethernet ports. The GS1910-24, GS1910-24HP, XGS1910-24 or XGS1910-48 also has four GbE dual personality interfaces. A dual personality interface includes one Gigabit Ethernet port and one slot for a miniGBIC transceiver (SFP module) with one port active at a time. The GS1910-48 and GS1910-48HP have four SFP slots.

The Ethernet ports on the GS1910-24HP or GS1910-48HP are all IEEE802.3at High Power over Ethernet (PoE) compliant and can supply power of up to 30W per Ethernet port.

CHAPTER 1

Getting to Know Your Switch

The XGS1910-24 or XGS1910-48 is stackable and provides two or four SFP+ slots for uplink or stacking. They can operate together with other XGS1910-24 or XGS1910-48 switches and need to be directly connected for stacking. The configurations are done on the master switch, which then maintains and manages the slave switches in the stack. You can stack up to eight XGS1910-24 or XGS1910-48 switches per stack.

With its built-in web configurator, managing and configuring the Switch is easy. In addition, the Switch can also be managed via third-party SNMP management.

1.1.1 Bridging Example

In this example the Switch connects different company departments (RD and Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via

the Switch. You can provide a super-fast uplink connection by using the optional 10 Gigabit uplink module on the Switch.

Figure 1 Bridging Application

1.1.2 High Performance Switching Example

The Switch is ideal for connecting two geographically dispersed networks that need high bandwidth. In the following example, a company uses the optional 10 Gigabit uplink modules to connect the headquarters to a branch office network. Within the headquarters network, a company can use trunking to group several physical ports into one logical higher-capacity link. Trunking can be used if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.

Figure 2 High Performance Switching

1.1.3 Gigabit Ethernet to the Desktop

Internet

The Switch is an ideal solution for small networks which demand high bandwidth for a group of heavy traffic users. You can connect computers and servers directly to the Switch’ s port or connect other switches to the Switch. Use the optional 10 Gigabit uplink module to provide high speed access to a data server and the Internet. The uplink module supports a fiber-optic connection which alleviates the distance limitations of copper cabling.

In this example, all computers can share high-speed applications on the server and access the Internet. To expand the network, simply add more networking devices such as switches, routers, computers, print servers and so on.

Figure 3 Gigabit to the Desktop

Chapter 1 Getting to Know Your Switch

1.1.4 IEEE 802.1Q VLAN Application Example

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one or more groups. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.

For more information on VLANs, refer to Chapter 9 on page 111.

1.1.4.1 Tag-based VLAN Example

Ports in the same VLAN group share the same frame broadcast domain, thus increasing network performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.

GS1910/XGS1910 Series User’s Guide

Chapter 1 Getting to Know Your Switch

Shared resources such as a server can be used by all ports in the same VLAN as the server. In the following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to other VLAN groups too.

Figure 4 Shared Server Using VLAN Example

1.1.5 IPv6 Support

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10 addresses. At the time of writing, the Switch supports the following features.

• Static address assignment and stateless auto-configuration

• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)

• Remote Management using ping SNMP, telnet and HTTP services

• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such as "ping”

• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time

• Multicast Listener Discovery (MLD) snooping and proxy

1.2 Ways to Manage the Switch

Use any of the following methods to manage the Switch.

• Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser.

• SNMP. The device can be monitored and/or managed by an SNMP manager.

1.3 Good Habits for Managing the Switch

Do the following things regularly to make the Switch more secure and to manage the Switch more effectively.

GS1910/XGS1910 Series User’s Guide

Chapter 1 Getting to Know Your Switch

• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.

• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Sw itch. Y ou could simply restore your last configuration.

Hardware Installation and

Connection

This chapter shows you how to install and connect the Switch.

2.1 Freestanding Installation

1 Make sure the Switch is clean and dry.

2 Set the Switch on a smooth, level surface strong enough to support the weight of

the Switch and the connected cables. Make sure there is a power outlet nearby.

3 Make sure there is enough clearance around the Switch to allow air circulation and

the attachment of cables and the power cord.

4 Remove the adhesive backing from the rubber feet.

5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber

feet help protect the Switch from shock or vibration and ensure space between devices when stacking.

Figure 5 Attaching Rubber Feet

GS1910/XGS1910 Series User’s Guide

Chapter 2 Hardware Installation and Connection

Note: Do NOT block the ventilation holes. Leave space between devices when

stacking.

Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front

and 3.4 inches (8 cm) at the back of the Switch. This is especially important for enclosed rack installations.

2.2 Mounting the Switch on a Rack

This section lists the rack mounting requirements and precautions and describes the installation steps.

2.2.1 Rack-mounted Installation Requirements

• Two mounting brackets.

• Eight M3 flat head screws and a #2 Philips screwdriver.

• Four M5 flat head screws and a #2 Philips screwdriver.

Failure to use the proper screws may damage the unit.

2.2.1.1 Precautions

• Mak e sure the r ack will safely sup port the combined weight of all the equipment it contains.

• Make sure the position of the Switch does not make the rack unstable or topheavy. Take all necessary precautions to anchor the rack securely before installing the unit.

2.2.2 Attaching the Mounting Brackets to the Switch

1 Position a mounting bracket on one side of the Switch, lining up the four screw

holes on the bracket with the screw holes on the side of the Switch.

3.1.1 Ethernet Ports

The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Gigabit Ethernet, the speed can be 10Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be both half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the connected device.

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straightthrough or crossover Ethernet cable.

3.1.1.1 Default Ethernet Settings

The factory default negotiation settings for the Ethernet ports on the Switch are:

• Speed: Auto

•Duplex: Auto

• Flow control: Off

• Dual Personality Interface: Fiber-optic module first

GS1910/XGS1910 Series User’s Guide

Chapter 3 Hardwar e Over vie w

3.1.2 Dual Personality Interfaces

There are four dual personality interfaces, comprising four 1000Base- T/SFP combo ports. For each interface you can connect either to the 1000Base- T port or the SFP slot. If an SFP transceiver is inserted in the SFP slot, the corresponding 1000BaseT port will be disabled.

Note: Connect the 1000Base-T RJ-45 port only after the transceiver is removed from

the corresponding SFP slot.

3.1.3 SFP/SFP+ Slots

These are slots for Small Form-Factor Pluggable (SFP) or SFP+ transceivers. The SFP is also referred to as a mini-GBIC. The SFP+ (SFP Plus) is an enhanced version of the SFP and supports data rates of 10 Gbps. A transceiver is a single unit that houses a transmitter and a receiver. Use a transceiver to connect a fiberoptic cable to the Switch. The Switch does not come with transceivers. You must use transceivers that comply with the Small Form-Factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.

You can change transceivers while the Switch is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic connectors.

• Type: SFP connection interface

• Connection speed: 1 Gigab it per second ( Gbps) or 10 Gig abit per second (Gbps )

To avoid possible eye injury, do not look into an operating fiberoptic module’s connectors.

3.1.3.1 Transceiver Installation

Use the following steps to install a transceiver (SFP or SFP+ module).

Figure 27 Initial Setup Example: Management IP Address

GS1910/XGS1910 Series User’s Guide 33

Chapter 5 Tutorials

1 Connect your computer to the Switch’s port which is in VLAN1 (the default management VLAN).

2 Open your web browser and enter 192.168.1.1 (the default management IP address) in the address

bar to access the web configurator. See Section 4.2 on page 25 for more information. Your computer must have an IP address in the range between “192.168.1.2” and “192.168.1.254”.

3 Log in with the admin account.

4 Click Configuration > System > IP in the navigation panel.

5 Enter 172.16.13.5 as the Switch’s new management IP

address, 255.255.255.0 as the subnet mask and

172.16.13.2 as the gateway’s IP address.

Alternatively, you can select the DHCP Client check box to have the Switch act as a DHCP client and get an IP address from the DHCP server to which the Switch is connected. Click Renew to update the IP address and DNS server information after you click Save. The IP address assigned by a DHCP server has priority over the IP address you manually configured.

6 The VLAN ID field lets you enter the ID of the VLAN group to which you want this management IP

address to belong. This is the same as the VLAN ID you configure in the Configuration > VLANs > VLAN Membership screen. In this example, leave the field at 1.

7 Click Save to save your changes back to the Switch.

Note: The Web Configurator may no longer be accessible unless you log in with the new

IP address. Check the DHCP server for the Switch’s dynamically assigned IP address when it is working as a DHCP client.

5.2 How to Configure Login Accounts and Privilege Levels

The admin account has a privilege level of 15, so the administrator can perform all types of system configuration. You cannot change the user name and privilege level of the admin account. You can create new login accounts the user used to log in to the Switch and manage the privilege levels for login accounts.

5.4 How to Create a VLAN

VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can do this using IEEE 802.1Q tagged static VLAN with fixed port members.

A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through Multiple VLAN Registration Protocol (MVRP). The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network.

Each port on the Switch is capable of passing tagged or untagged frames. To forward a frame from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the Switch first decides where to forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLANunaware switch to an 802.1Q VLAN-aware switch, the Switch first decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port's default VID. The default PVID is VLAN 1 for all ports, but this can be changed.

A broadcast frame (or a multicast frame for a multicast group that is known by the system) is duplicated only on ports that are members of the VID (except the ingress port itself), thus confining the broadcast to a specific domain.

By default, all ports on the Switch are in VLAN 1. In this example, you want to configure port 1 as a member of VLAN 2.

5.5 How to Set Up a Guest VLAN with IEEE 802.1x Authentication

All ports on the Switch are in VLAN 1 by default. Say you enable IEEE 802.1x authentication on ports 1 to 8. Clients that connect to these ports should provide the correct user name and password in order to access the ports. You want to assign clients that connect to ports 1, 2 or 3 to a guest VLAN (200 for example) when they fail to authenticate with the authentication server. In this guest VLAN, clients can surf the Internet through a gateway attached to port 10, but are not allowed to access other network resources, such as the mail server or local data base.

5.5.1 Creating a VLAN for Port which is not IEEE 802.1x enabled

Follow the steps below to configure port 10 as a member of VLAN 200.

1 Access the web configurator through the Switch’s port which is not in VLAN 200.

2 Click Configuration > VLANs > VLAN Membership in the navigation panel. Click Add New

6 Click Configuration > VLANs > Ports in the navigation panel.

7 Set Port VLAN Mode to Specific and enter 200 in the Port VLAN ID field for port 10 to add a tag

to incoming untagged frames received on these ports so that the frames are forwarded to the VLAN group that the tag defines.

8 To ensure that VLAN-unaware devices (such as computers and hubs) can receive frames properly,

select Untag_all in the TX Tag field to set the Switch to remove VLAN tags before sending frames out of these ports.

9 click Save to save your changes back to the Switch.

5.6 How to Use Private VLAN to Do Port Isolation in a VLAN

This tutorial is not applicable to the XGS1910-24 or XGS1910-48.

Port isolation prevents communication between ports. You want to do port isolation in a VLAN but still allow ports to access the Internet or network resources through the uplink port in the same VLAN. You use private VLAN to do port isolation in a VLAN instead of assigning each port to a separate VLAN and creating a different IP routing domain for each individual port.

By default, all ports on the Switch are in VLAN 1 and private VLAN 1. An isolated port is a port on which port isolation is enabled. An isolated port cannot communicate with other isolated ports even when they are in the same VLAN and same private VLAN.

In this example, you put ports 2 to 4 and 25 in private VLAN 25 and enable port isolation to block traffic between ports 2, 3 and 4.

5.6.1 Creating a Private VLAN

Follow the steps below to configure port 2, 3, 4 and 25 as a member of private VLAN 25.

1 Access the web configurator through the Switch’s port on which port isolation will not be enabled.

2 Go to Configuration > Private VLANs > PVLAN Membership. Click Add New Private VLAN.

3 Enter a private VLAN ID (25 for example) in the PVLAN ID field.

4 Select ports 2, 3, 4 and 25 to be members of this private VLAN.

2 Select the check boxes of ports 2, 3 and 4, and click Save to add them to the isolated port list so

that they cannot send traffic to each other.

Chapter 5 Tutorials

From port 2, 3, or 4, you should be able to access the device that attaches to port 25, such as a server or default gateway.

5.7 How to Use IP Source Guard and DHCP Snooping to Prevent Spoofed Traffic

IP source guard uses a binding table to allow or block IP traffic in your network. When the Switch receives an IP packet, it looks up the appropriate MAC address, VLAN ID, IP address, and port number in the binding table. If there is a binding, the Switch forwards the packet. If there is not a binding, the Switch discards the packet.

The Switch builds the binding table by snooping DHCP packets (dynamic bindings) and from information provided manually by administrators (static bindings).

Use DHCP snooping to filter unauthorized DHCP packets on the network and to build the binding table dynamically. This can prevent clients from getting IP addresses from unauthorized DHCP servers.

GS1910/XGS1910 Series User’s Guide

Chapter 5 Tutorials

VLAN 100

If you want to use dynamic bindings to filter unauthorized ARP packets (typical implementation), you have to enable DHCP snooping before you enable ARP inspection.

T rusted vs. Untrusted Ports

Every port is either a trusted port or an untrusted port for DHCP snooping.

T rusted ports are connected to DHCP servers or other switches. The Switch learns dynamic bindings from trusted ports.

Note: The Switch will drop all DHCP requests if you enable DHCP snooping and there are

Untrusted ports are connected to subscribers. The Switch discards DHCP packets from untrusted ports in the following situations:

• The packet is a DHCP server packet (for example, OFFER, ACK, or NACK).

• The source MAC address and source IP address in the packet do not match any of the current bindings.

• The packet is a RELEASE or DECLINE packet, and the source MAC address and source port do not match any of the current bindings.

no trusted ports.

In the following example, you only want DHCP server A connected to port 5 to assign IP addresses to all devices in VLAN 100. Create a VLAN containing ports 5, 6 and 7. Connect a computer (M) to the Switch’s port which is not in VLAN 100.

The settings in this tutorial are as the following.

5.8 How to Use DHCP Relay on the Switch

If the DHCP clients and the DHCP server are not in the same broadcast domain, the Switch can help to relay network information (such as the IP address and subnet mask) between a DHCP client and a DHCP server. This tutorial describes how to configure your Switch to forward DHCP client requests to a specific DHCP server. The DHCP server can then assign a specific IP address based on the information in the DHCP requests.

In this example, you have configured your DHCP server (192.168.2.3) and want to have it assign a specific IP address (say 172.16.1.18) and gateway information to DHCP client A based on the slot

4 Select Enabled in the Relay Information Mode field to allow the Switch to add relay agent

information (such as the VLAN ID) to DHCP requests.

5 Select Replace in the Relay Information Policy field to have the Switch remove the original

DHCP relay agent information (if any) and add new information in the DHCP requests.

6 Click Save to save your changes back to the Switch.

5.9 How to Use Link Aggregation to Group Multiple Ports into One Logical Link

Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.

However, the more ports you aggregate then the fewer available ports you have. A trunk group is one logical link containing multiple ports.

The beginning port of each trunk group must be physically connected to form a trunk group.

The Switch supports both static and dynamic link aggregation. The Switch supports the IEEE

802.3ad standard for static and dynamic (LACP) port trunking. This standard describes the Link

Aggregation Control Protocol (LACP), which is a protocol that dynamically creates and manages trunk groups.

Note: In a properly planned network, it is recommended to implement static link

aggregation only. This ensures increased network stability and control over the trunk groups on your Switch.

5.9.1 Static Port Trunking

This example shows you how to create a static port trunk group for ports 2-5.

1 Make your physical connections - make sure that the ports that you want to belong to the trunk

group are connected to the same destination. The following figure shows ports 2-5 on switch A connected to switch B.

GS1910/XGS1910 Series User’s Guide

Chapter 5 Tutorials

2 Configure static trunking - Click Configuration > Aggregation > Static. In this screen select

the traffic distribution type(s) used by this group and select the ports that should belong to this group as shown in the figure below. Packets from the same source and/or to the same destination are sent over the same link within the trunk. If the Switch is behind a router, the packet’s destination or source MAC address will be changed. In this case, set the Switch to distribute traffic based on its IP address to make sure port trunking can work properly.

Click Save when you are done.

5.9.2 Dynamic Port Trunking

When you enable LACP link aggregation on a port, the port can automatically negotiate with the ports at the remote end of a link to establish trunk groups. LACP also allows port redundancy, that is, if an operational port fails, then one of the “standby” ports become operational without user intervention. Please note that:

• You must connect all ports point-to-point to the same Ethernet Switch and configure the ports for LACP trunking.

• LACP only works on full-duplex links.

• All ports in the same trunk group must have the same media type, speed, duplex mode and flow control settings.

5.10 How to Analyze Traffic Using Mirroring

With mirroring, you can copy a traffic flow (passing through the source port(s)) to another port (a destination port you copy the traffic to) in order that you can examine the traffic from the destination port without interference.

You can also use remote port mirroring to monitor multiple switches across your network. In remote port mirroring, the traffic from the source port(s) is forwarded to a specific remote port mirroring VLAN through a reflector port and copied to an intermediate port. Traffic are then carried over the VLAN and sent to a destination port in a remote switch through the intermediate ports that connect to other switches.

GS1910/XGS1910 Series User’s Guide

5.11 How to Use IGMP Snooping to Reduce Multicast Traffic Passing through your Switch

The Switch can passively snoop on IGMP packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the Switch to learn multicast groups without you having to manually configure them.

The Switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your Switch.

The Switch can perform IGMP snooping on up to 32 VLANs. You can configure the Switch to automatically learn multicast group membership of any VLANs.

GS1910/XGS1910 Series User’s Guide

Chapter 5 Tutorials

Proxy

Follow the steps below to enable IGMP snooping on the Switch and a specific VLAN. You also have the Switch act as an IGMP proxy to report group changes to a connected multicast router (R).

1 Access the Switch through http://192.168.1.1. Log into the Switch by entering the username

(default: admin) and password (default: 1234).

2 Go to Configuration > IPMAC > IGMP Snooping > Basic Configuration. Select the Snooping

Enabled check box to activate IGMP snooping on the Switch.

3 The Unknown Multicast Flooding Enabled check box is selected by default and the Switch will

send the frame(s) to all ports when the it receives an unknown multicast frame.

4 In the IGMP SSM Range field, specify the source address range of the multicast group the clients

will listen to. The Switch forwards the packets with the configured source address(es) to the clients that join this group. This help prevent the clients from receiving traffic resulting from unwanted sources.

5 Set Leave Proxy Enabled and Proxy Enabled to allow the Switch to send a leave message with

its MAC address to the multicast router/switch only when it receives the leave message from the last host in a multicast group. The Switch also replaces the source MAC address in an IGMP v1/v2 report with its own MAC address before forwarding to the multicast router/switch. When the Switch receives more than one IGMP v1/v2 join reports that request to join the same multicast group, it only sends a new join report with its MAC address. This helps reduce the number of multicast join and leave messages passed to the multicast router/switch.

6 Select a router port (port 1 in this example) that connects to the multicast router or switch. The

Switch forwards IGMP control messages (Query, Join and Leave) to the router port.

7 Enable Fast Leave on the ports that connect to the hosts/clients (ports 7, 8 and 9 in this example).

In fast leave mode, the Switch removes an IGMP snooping membership entry immediately from the forwarding table when an IGMP leave message is received on the port from a host. This helps speed up the leave process.

8 Also set the maximum number of multicast groups the ports can join.

9 Click Save.

10 Configure both the router port and the ports to which the multicast clients connect as a member of

VLAN 1234. See Section 5.4 on page 38 for how to create a VLAN and configure ports to join the VLAN.

11 Go to Configuration > IPMAC > IGMP Snooping > VLAN Configuration.

12 Select Snooping Enabled for VLAN 1234 to allow the Switch to learn the IP multicast group

membership of this VLAN.

13 Select IGMP Querier for VLAN 1234 to allow the Switch to act as the querier in the VLAN to send

IGMP General Query (GQ) and Group-Specific Query (GSQ) messages to this VLAN. A querier sends out an IGMP Group-Specific Query (GSQ) message to determine whether the hosts connected to the port should remain in the specific multicast group.

5.12 How to Configure Access Control List (ACL) for Packets Filtering

Access Control List (ACL) can be used as a simple packet filtering firewall to filter incoming traffic and prevent certain traffic from entering your network. ACL groups traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming port number, and also define actions to be performed for a classified traffic flow.

The Switch checks traffic against the ACL rules in the order you list them.

In this example, you configure an ACL rule to identify all traffic coming from host A connected to port 9 and restrict the host’s access to a specific IPv4 network.

1 Access the Switch through http://192.168.1.1. Log into the Switch by entering the username

(default: admin) and password (default: 1234).

GS1910/XGS1910 Series User’s Guide

Chapter 5 Tutorials

2 Go to Configuration > Security > Network > ACL > Access Control List. Click the Add icon

to create a new ACL policy.

3 Select the port on which the matched traffic is received (All ports in this example).

4 Set Policy Filter to Specific and Policy Bitmask to 0xff to give this policy one ID number in the

Policy Value field. You then can apply this policy to a port using this policy ID.

5 Select IPv4 in the Frame Type field.

6 Select Network in the DIP Filter field and specify the destina t ion address and subnet ma sk of

matched traffic in this policy.

7 Set Action to Deny to block all mattached traffic.

8 Click Save. The ordering of your rules is very important as rules are applied in the order that they

are listed. This tutorial uses the XGS1910-24 screens as an example. The screens may vary slightly for

different models.

9 Go to Configuration > Security > Network > ACL > Ports. Enter the ID of the ACL policy you

just created in the Policy ID field of the port to which you want to apply this policy, that is, port 9 to which host A is connected in this example.

10 Click Save. The ACL configurations in the Ports page (such as Action or Rate Limiter ID) apply

only to traffic that does NOT matched the specified ACL policy.

5.13 How to Reset the Switch via the Console Port

If you lock yourself (and others) from the Switch or forget the administrator password, you will need to reload the factory-default configuration file or reset the S w itch back to the factory defaults.

Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity , one stop bit and flow control set to none. The password will also be reset to “1234” and the IP address to

192.168.1.1.

To upload the configuration file, do the following:

1 Connect to the console port using a computer with terminal emulation software. See Section 3.1.4

on page 20 for details.

2 Disconnect and reconnect the Switch’s power to begin a session. When you reconnect the Switch’s

power, you will see the initial screen.

3 When you see the message “Executing boot script in 3.000 seconds - enter ^C to abort”

press the Ctrl-c key combination to stop the automatic boot and then type default.

4 Type reset after the “Erase from 0x40080000-0x4017ffff: ................” message.
