Limited Warranty

Hardware:

D-Link warrants each of its hardware products to be free from defects in workmanship and materials under normal use and service for a period commencing on the date of purchase from D-Link or its Authorized Reseller and extending for the length of time stipulated by the Authorized Reseller or D-Link Branch Office nearest to the place of purchase.

This Warranty applies on the condition that the product Registration Card is filled out and returned to a D-Link office within ninety (90) days of purchase. A list of D-Link offices is provided at the back of this manual, together with a copy of the Registration Card.

If the product proves defective within the applicable warranty period, D-Link will provide repair or replacement of the product. D-Link shall have the sole discretion whether to repair or replace, and replacement product may be new or reconditioned. Replacement product shall be of equivalent or better specifications, relative to the defective product, but need not be identical. Any product or part repaired by D-Link pursuant to this warranty shall have a warranty period of not less than 90 days, from date of such repair, irrespective of any earlier expiration of original warranty period. When D-Link provides replacement, then the defective product becomes the property of D-Link.

Warranty service may be obtained by contacting a D-Link office within the applicable warranty period, and requesting a Return Material Authorization (RMA) number. If a Registration Card for the product in question has not been returned to D-Link, then a proof of purchase (such as a copy of the dated purchase invoice) must be provided. If Purchaser's circumstances require special handling of warranty correction, then at the time of requesting RMA number, Purchaser may also propose special procedure as may be suitable to the case.

After an RMA number is issued, the defective product must be packaged securely in the original or other suitable shipping package to ensure that it will not be damaged in transit, and the RMA number must be prominently marked on the outside of the package. The package must be mailed or otherwise shipped to D-Link with all costs of mailing/shipping/insurance prepaid. D-Link shall never be responsible for any software, firmware, information, or memory data of Purchaser contained in, stored on, or integrated with any product returned to D-Link pursuant to this warranty.

Any package returned to D-Link without an RMA number will be rejected and shipped back to Purchaser at Purchaser's expense, and D-Link reserves the right in such a case to levy a reasonable handling charge in addition mailing or shipping costs.

Software:

Warranty service for software products may be obtained by contacting a D-Link office within the applicable warranty period. A list of D-Link offices is provided at the back of this manual, together with a copy of the Registration Card. If a Registration Card for the product in question has not been returned to a D-Link office, then a proof of purchase (such as a copy of the dated purchase invoice) must be provided when requesting warranty service. The term "purchase" in this software warranty refers to the purchase transaction and resulting license to use such software.

D-Link warrants that its software products will perform in substantial conformance with the applicable product documentation provided by D-Link with such software product, for a period of ninety (90) days from the date of purchase from D-Link or its Authorized Reseller. D-Link warrants the magnetic media, on which D-Link provides its software product, against failure during the same warranty period. This warranty applies to purchased software, and to replacement software provided by D-Link pursuant to this warranty, but shall not apply to any update or replacement which may be provided for download via the Internet, or to any update which may otherwise be provided free of charge.

D-Link's sole obligation under this software warranty shall be to replace any defective software product with product which substantially conforms to D-Link's applicable product documentation. Purchaser assumes responsibility for the selection of appropriate application and system/platform software and associated reference materials. D-Link makes no warranty that its software products will work in combination with any hardware, or any application or system/platform software product provided by any third party, excepting only such products as are expressly represented, in D-Link's applicable product documentation as being compatible.

xStack Gigabit Layer 3 Switch Command Line Interface Manual

INTRODUCTION

The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The Command Line Interface (CLI) can be used to configure and manage the Switch via the serial port or Telnet interfaces.

This manual provides a reference for all of the commands contained in the CLI for members of the xStack family, including the DGS-3324SRi, DGS-3324SR, DXS-3326GSR and the DXS-3350SR. Examples present in this manual may refer to any member of the xStack family and may show different port counts, but are universal to this series of switches, unless otherwise stated. Configuration and management of the Switch via the Web-based management agent is discussed in the User’s Guide.

Accessing the Switch via the Serial Port

The Switch’s serial port’s default settings are as follows:

• 115200 baud

• no parity

• 8 data bits

• 1 stop bit

A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above is then connected to the Switch’s serial port via an RS-232 DB-9 cable.

With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not appear, try pressing Ctrl+r to refresh the console screen.

Figure 1-1. Initial CLI screen

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3324SRi:4#. This is the command line where all commands are input.

Page 10

xStack Gigabit Layer 3 Switch Command Line Interface Manual

Setting the Switch’s IP Address

Each switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default switch IP address to meet the specification of your networking address scheme.

The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found on the initial boot console screen – shown below.

Figure 1-2. Boot Screen

The Switch’s MAC address can also be found in the Web management program on the Switch Information (Basic Settings) window on the Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

1. Starting at the command line prompt, enter the commands config ipif System ipaddress

xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.

2. Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

Page 11

xStack Gigabit Layer 3 Switch Command Line Interface Manual

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.53.13.144 with a subnet mask of 255.0.0.0. The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

Page 12

xStack Gigabit Layer 3 Switch Command Line Interface Manual

USING THE CONSOLE CLI

The xStack family of switches supports a console management interface that allows the user to connect to the Switch’s management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the Switch to use an SNMP-based network management software over the network.

This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation.

Note: Switch configuration settings are saved to non-volatile RAM using the save command. The current configuration will then be retained in the Switch’s NV-RAM, and reloaded when the Switch is rebooted. If the Switch is rebooted without using the save command, the last configuration saved to NV-RAM will be loaded.

Connecting to the Switch

The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C serial cable. Your terminal parameters will need to be set to:

• VT-100 compatible

• 115200 baud

• 8 data bits

• No parity

• One stop bit

• No flow control

You can also access the same functions over a Telnet interface. Once you have set an IP address for your Switch, you can use a Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether accessed from the console port or from a Telnet interface.

After the Switch reboots and you have logged in, the console looks like this:

Page 13

xStack Gigabit Layer 3 Switch Command Line Interface Manual

Figure 2-1. Initial Console Screen

Commands are entered at the command prompts, DGS-3324SRi:4#, DGS-3324SR:4#, DXS-3326GSR:4#, DXS-3350SR:4#.

There are a number of helpful features included in the CLI. Entering the ? command will display a list of all of the top-level commands.

Figure 2-2. The ? Command

When you enter a command without its required parameters, the CLI will prompt you with a Next possible completions: message.

Page 14

xStack Gigabit Layer 3 Switch Command Line Interface Manual

Figure 2-3. Example Command Parameter Help

In this case, the command config account was entered with the parameter <username>. The CLI will then prompt you to enter the <username> with the message, Next possible completions:. Every command in the CLI has this feature, and complex commands have several layers of parameter prompting.

In addition, after typing any given command plus one space, you can see all of the next possible sub-commands, in sequential order, by repeatedly pressing the Tab key.

To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous command will appear at the command prompt.

Figure 2-4. Using the Up Arrow to Re-enter a Command

In the above example, the command config account was entered without the required parameter <username>, the CLI returned the Next possible completions: <username> prompt. The up arrow cursor control key was pressed to re-enter the previous command (config account) at the command prompt. Now the appropriate User name can be entered and the config account command re-executed.

Page 15

xStack Gigabit Layer 3 Switch Command Line Interface Manual

All commands in the CLI function in this way. In addition, the syntax of the help prompts are the same as presented in this manual − angle brackets < > indicate a numerical value or character string, braces { } indicate optional parameters or a choice of parameters, and brackets [ ] indicate required parameters.

If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed under the Available commands: prompt.

Figure 2-5. The Available Commands Prompt

The top-level commands consist of commands such as show or config. Most of these commands require one or more parameters to narrow the top-level command. This is equivalent to show what? or config what? Where the what? is the next parameter.

For example, if you enter the show command with no additional parameters, the CLI will then display all of the possible next parameters.

Figure 2-6. Next possible completions: Show Command

Page 16

xStack Gigabit Layer 3 Switch Command Line Interface Manual

In the above example, all of the possible next parameters for the show command are displayed. At the next command prompt, the up arrow was used to re-enter the show command, followed by the account parameter. The CLI then displays the user accounts configured on the Switch.

config or system. It is not necessary to specify either optional

value, however the effect of the system reset is dependent on

which, if any, value is specified. Therefore, with this example

there are three possible outcomes of performing a system

reset. See the following chapter, Basic Commands for more

Example command

all − Configure all ports on the Switch.

<portlist> − Specifies a range of ports to be configured. The port

list is specified by listing the lowest switch number and the beginning port number on that switch, separated by a colon. Then the highest switch number, and the highest port number of the range (also separated by a colon) are specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in numerical order.

[master | slave] – The master and slave parameters refer to connections running a 1000BASE-T cable for connection between the Switch port and other device capable of a gigabit connection. The master setting will allow the port to advertise capabilities related to duplex, speed and physical layer type. The master setting will also determine the master and slave relationship between the two connected physical layers. This relationship is necessary for establishing the timing control between the two physical layers. The timing control is set on a master physical layer by a local source. The slave setting uses loop timing, where the timing comes form a data stream received from the master. If

Description This command is used to configure the system severity levels on the

Switch. When an event occurs on the Switch, a message will be sent to the SNMP agent (trap), the Switch’s log or both. Events occurring on the Switch are separated into three main categories.

• Information – Events classified as information are basic events

occurring on the Switch that are not deemed as problematic, such as enabling or disabling various functions on the Switch.

• Warning - Events classified as warning are problematic events

that are not critical to the overall function of the Switch but do require attention, such as unsuccessful downloads or uploads and failed logins.

• Critical – Events classified as critical are fatal exceptions

occurring on the Switch, such as hardware failures or spoofing attacks.

Parameters Choose one of the following to identify where severity messages are

to be sent.

• trap – Entering this parameter will define which events

occurring on the Switch will be sent to a SNMP agent for analysis.

MULTIPLE SPANNING TREE PROTOCOL (MSTP) COMMANDS

This switch supports three versions of the Spanning Tree Protocol; 802.1d STP, 802.1w Rapid STP and 802.1s MSTP. Multiple Spanning Tree Protocol, or MSTP, is a standard defined by the IEEE community that allows multiple VLANs to be mapped to a single spanning tree instance, which will provide multiple pathways across the network. Therefore, these MSTP configurations will balance the traffic load, preventing wide scale disruptions when a single spanning tree instance fails. This will allow for faster convergences of new topologies for the failed instance. Frames designated for these VLANs will be processed quickly and completely throughout interconnected bridges utilizing either of the three spanning tree protocols (STP, RSTP or MSTP). This protocol will also tag BDPU packets so receiving devices can distinguish spanning tree instances, spanning tree regions and the VLANs associated with them. These instances will be classified by an instance_id. MSTP will connect multiple spanning trees with a Common and Internal Spanning Tree (CIST). The CIST will automatically determine each MSTP region, its maximum possible extent and will appear as one virtual bridge that runs a single spanning tree. Consequentially, frames assigned to different VLANs will follow different data routes within administratively established regions on the network, continuing to allow simple and full processing of frames, regardless of administrative errors in defining VLANs and their respective spanning trees. Each switch utilizing the MSTP on a network will have a single MSTP configuration that will have the following three attributes:

a) A configuration name defined by an alphanumeric string of up to 32 characters (defined in the config stp mst_config_id

command as name <string>).

b) A configuration revision number (named here as a revision_level) and;

c) A 4096 element table (defined here as a vid_range) which will associate each of the possible 4096 VLANs supported

by the Switch for a given instance.

To utilize the MSTP function on the Switch, three steps need to be taken:

a) The Switch must be set to the MSTP setting (config stp version)

b) The correct spanning tree priority for the MSTP instance must be entered (config stp priority).

c) VLANs that will be shared must be added to the MSTP Instance ID (config stp instance_id).

The Multiple Spanning Tree Protocol commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Parameters

config stp {maxage <value 6-40> | maxhops <value 1-20> | hellotime <1-10> | forwarddelay <value 4-30> | txholdcount <value 1-10> | fbpdu [enable | disable]}

for the entire switch. All commands here will be implemented for the STP version that is currently set on the Switch.

maxage <value 6-40> − This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the

Page 88

config stp

xStack Gigabit Layer 3 Switch Command Line Interface Manual

value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that your switch has the lowest Bridge Identifier, it will become the Root Bridge. The user may choose a time between 6 and 40 seconds. The default value is 20.

maxhops <value 1-20> - The number of hops between devices in a spanning tree region before the BPDU (bridge protocol data unit) packet sent by the Switch will be discarded. Each switch on the hop count will reduce the hop count by one until the value reaches zero. The Switch will then discard the BDPU packet and the information held for the port will age out. The user may set a hop count from 1 to 20. The default is 20.

hellotime <value 1-10> − The user may set the time interval between transmission of configuration messages by the root device in STP, or by the designated router in RSTP, thus stating that the Switch is still functioning. A time between 1 and 10 seconds may be chosen, with a default setting of 2 seconds.

In MSTP, the spanning tree is configured by port and therefore, the hellotime must be set using the configure stp ports command for switches utilizing the Multiple Spanning Tree Protocol.

Restrictions Only administrator-level users can issue this command.

Example usage:

To configure STP with maxage 18 and maxhops of 15:

forwarddelay <value 4-30> − The maximum amount of time (in seconds) that the root device will wait before changing states. The user may choose a time between 4 and 30 seconds. The default is 15 seconds.

txholdcount <value 1-10> - The maximum number of BDPU Hello packets transmitted per interval. Default value = 3.

fbpdu [enable | disable] − Allows the forwarding of STP BPDU packets from other network devices when STP is disabled on the Switch. The default is enable.

DGS-3324SRi:4#config stp maxage 18 maxhops 15

Command: config stp maxage 18 maxhops 15

Success.

DGS-3324SRi:4#

config stp ports

Purpose Used to setup STP on the port level.

Syntax

config stp ports <portlist> {externalCost [auto | <value 1200000000>] | hellotime <value 1-10> | migrate [yes | no] edge [true | false] | p2p [true | false | auto ] | state [enable | disable]

Page 89

xStack Gigabit Layer 3 Switch Command Line Interface Manual

config stp ports

Description This command is used to create and configure STP for a group of

ports.

Parameters

<portlist> − Specifies a range of ports to be configured. The port list is specified by listing the lowest switch number and the beginning port number on that switch, separated by a colon. Then the highest switch number, and the highest port number of the range (also separated by a colon) are specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in numerical order.

externalCost − This defines a metric that indicates the relative cost of forwarding packets to the specified port list. Port cost can be set automatically or as a metric value. The default value is auto.

  auto – Setting this parameter for the external cost will automatically set the speed for forwarding packets to the specified port(s) in the list for optimal efficiency. Default port cost: 100Mbps port = 200000. Gigabit port = 20000.

<value 1-200000000> - Define a value between 1 and 200000000 to determine the external cost. The lower the number, the greater the probability the port will be chosen to forward packets.

hellotime <value 1-10> − The time interval between transmission of configuration messages by the designated port, to other devices on the bridged LAN, thus stating that the Switch is still functioning. The user may choose a time between 1 and 10 seconds. The default is 2 seconds.

migrate [yes | no] – Setting this parameter as “yes” will set the ports to send out BDPU packets to other bridges, requesting information on their STP setting If the Switch is configured for RSTP, the port will be capable to migrate from 802.1d STP to

802.1w RSTP. If the Switch is configured for MSTP, the port is capable of migrating from 802.1d STP to 802.1s MSTP. RSTP and MSTP can coexist with standard STP, however the benefits of RSTP and MSTP are not realized on a port where an 802.1d network connects to an 802.1w or 802.1s enabled network. Migration should be set as yes on ports connected to network stations or segments that are capable of being upgraded to

802.1w RSTP or 802.1s MSTP on all or some portion of the segment.

edge [true | false] – true designates the port as an edge port. Edge ports cannot create loops, however an edge port can lose edge port status if a topology change creates a potential for a loop. An edge port normally should not receive BPDU packets. If a BPDU packet is received it automatically loses edge port status.

false indicates that the port does not have edge port status.

p2p [true | false | auto] – true indicates a point-to-point (P2P)

shared link. P2P ports are similar to edge ports however they are restricted in that a P2P port must operate in full-duplex. Like edge ports, P2P ports transition to a forwarding state rapidly thus benefiting from RSTP. A p2p value of false indicates that the port cannot have p2p status. auto allows the port to have p2p status whenever possible and operate as if the p2p status were true. If the port cannot maintain this status (for example if the port is
