INTRODUCTION

The xStack® DGS–3400 Series is a member of the D–Link xStack® switch family. xStack® is a complete family of stackable switches that range from edge 10/100Mbps switches to core Gigabit switches. xStack tolerance, scalable flexibility, robust security, standard–based interoperability and an impressive support for 10–Gigabit technology to future–proof departmental and enterprise network deployments with an easy migration path.
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. Configuration and management of the Switch via the Web–based management agent is discussed in the Manual. For detailed information on installing hardware please refer also to the Manual.

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 o 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–3426:5#. This is the command line where all commands are input.

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 chang ed, 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.
DGS–3426:5#config ipif System ipaddress 10.73.21.35/255.0.0.0 Command:config ipif System ipaddress 10.73.21.35/8
Success.
Figure 1–3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.73.21.35 with a subn et mask of 255 .0 .0.0 . Th e system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet, SNMP MIB browser and the CLI or via the Web–based management agent using the above IP address to connect to the Switch.
Note: The DGS–3400 series of switches have the capability to be configured for an IP address of
0.0.0.0, or, in essence, have no IP address. This function maybe used to disable Layer 3 functions of the Switch. When the IP address is set to 0.0.0.0 (invalid IP address), the Switch can only be managed through the console port or SIM. Other management applications such as Telnet, Web– based and SNMP cannot be used to manage the Switch when its IP address is 0.0.0.0.

USING THE CONSOLE CLI

The Switch 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
Users may 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:

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 username can be entered and the config account command re–executed.
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 paramet ers.
If a command is entered that is unrecognized by the CLI, the top–level commands will be displayed under the Available commands: prompt.

Description This command allows for the configuration of the Switch’s Ethernet ports. Only the ports
Parameters
[<portlist> | all ] {medium_type [fiber | copper]} {speed [auto {capability_advertised {10_half | 10_full | 100_half | 100_full | 1000_full} (1) } | 10_half | 10_full | 100_half | 100_full | 1000_full { [master | slave] } ] | auto_negotiation restart_an | flow_control [enable | disable] | learning [enable | disable ] | state [enable | disable] | [description <desc 1-32> | clear_description]} (1)
listed in the <portlist> will be affected. all Configure all ports on the Switch.
<portlist> Specifies a port or 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. Non–contiguous portlist entries are separated by a comma. (ex: 1:1–1:3,1:7–1:9)
medium_type [fiber | copper] – This applies only to the Combo ports. If configuring the Combo ports this defines the type of transport medium used.
speed – Allows the user to adjust the speed for a port or range of ports. The user has a choice of the following:
auto Enables auto–negotiation for the specified range of ports.
capability advertised – Configures the capability that advertises to the link partner
to determine the fastest available auto setting.
[10 | 100 | 1000] − Configures the speed in Mbps for the specified range of ports. Gigabit ports are statically set to 1000 and cannot be set to slower speeds.
[half | full] Configures the specified range of ports as either full–duplex or half– duplex.
[master | slave] – The master setting (1000M/Full_M) 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 (1000M/Full_S) uses loop timing, where the timing comes form a data stream received from the master. If one connection is set for 1000M/Full_M, the other side of the connection must be set for 1000M/Full_S. Any other configuration will result in a link down status for both ports.

config box_priority current_box_id <value 1–12> priority <value 1–63> config box_id current_box_id <value 1–12> new_box_id [auto | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
12] show stack_information config stacking mode [disable | enable] {<string>} show stacking mode show stack_device
Each command is listed, in detail, in the following sections.
config box_priority
Purpose Used to configure box priority, which determines which box becomes the priority master.
Lower numbers denote a higher priority. Syntax Description This command configures box (switch) priority. Parameters current_box_id <value 1–12> – Identifies the Switch being configured. Range is 1–12.
Restrictions Only Administrator and Operator-level users can issue this command.
Usage example: To configure box priority:
DGS–3426:5#config box_priority current_box_id 1 priority 1 Command: config box_priority current_box_id 1 priority 1
Success.
DGS–3426:5#
config box_priority {current_box_id <value 1–12> priority <value 1–63>}
priority <value 1–63> – Assigns a priority value to the box, with lower numbers having
higher priority. The possible priority range is 1–63. This field is important when the
stacking mode is automatically configured. Users who wish a certain switch become the
primary master of the switch stack should configure their choice for the priority master
switch to have the highest priority (and in essence the lowest number).
config box_id
Purpose Used to configure box ID. Users can use this command to reassign box IDs. Syntax
Description This command will assign box IDs to switches in a stack. Parameters current_box_id – Identifies the Switch being configured. Range is 1–12.
Restrictions Only Administrator and Operator-level users can issue this command.
config box_id {current_box_id <value 1–12> new_box_id [auto | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12]}
new_box_id – The new ID being assigned to the Switch (box). Range is 1–12.
auto – Allows the box ID to be assigned automatically.

Message integrity − ensures that packets have not been tampered with during transit.
Authentication determines if an SNMP message is from a valid source.
Encryption scrambles the contents of messages to prevent it being viewed by
an unauthorized source.
noauth_nopriv
sent between the Switch and a remote SNMP manager. auth_nopriv Specifies that authorization will be required, but there will be no encryption
of packets sent between the Switch and a remote SNMP manager. auth_priv − Specifies that authorization will be required, and that packets sent between
the Switch and a remote SNMP manger will be encrypted. <auth_sting 32> − An alphanumeric string used to authorize a remote SNMP manager to
access the Switch’s SNMP agent.

This is exactly the same as using a download config command. After the entire Switch configuration is loaded, the Switch will automatically “logout” the server.
Upon booting up the autoconfig process is initiated, the console screen will appear similar to the example below. The configuration settings will be loaded in normal order.

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 proto cols (STP, RSTP or MSTP). This protocol will also tag BDPU packets so receiving devices can distinguish spanning tree instances, spann ing 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 spann ing tree. Consequ entially, frames assigned to different VLANs will follow different data routes within administratively established regions on th e 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 insta nce_id).
The Multiple Spanning Tree Protocol commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Purpose Used to setup STP, RSTP, and MSTP on the Switch. Syntax
Description This command is used to setup the Spanning Tree Protocol (STP) for the entire switch. All
Parameters
config stp {maxage <value 6-40>|maxhops <value 1-40> |h ellotime <value 1-10>| forwarddelay <value 4-30>|txholdcount <value 1-10>|fbpdu [enable|disable]|lbd [enable|disable] |lbd_recover_timer [<value 0> | <value 60-1000000>]|nni_b pdu_addr [dot1d | dot1ad]} (1)
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 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 defau lt value is 20.
maxhops <value 1–40> – 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 40. The default is 20. If the entered value is less than 6, the maxhops will be 6.
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. If the value is more than 2, the hellotime will be 2.
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.
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 = 6.
fbpdu [enable | disable] − Allows the forwarding of STP BPDU packets from other network devices when STP is disabled on the Switch. The default is disable.
lbd [enable | disable] – When this is enabled, the Switch will temporarily block STP switch– wide when a BDPU packet has been looped back. If the Switch detects its own BDPU packet coming back, it signifies a loop on the network. STP will automatically be blocked and an alert will be sent to the administrator. The default is enable.
lbd_recover_timer [ 0 | < second 60 –1000000 > ] – Time allowed for recovery after an STP
84

config stp
loopback has been detected. After the timer has expired the Switch checks for an STP loopback, if no loopback detected, STP will be resumed. Entering 0 will disable LBD recovery.
nni_bpdu_addr [dot1d | dot1ad] – Used to determine the BPDU protocol address for STP in a service provided site. It can use 802.1d STP address, 802.1ad service provider STP address o r a user defined mutilcast address. The range of the user defined address is 0180C2000000 ­0180C2FFFFFF.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To configure STP with maxage 18 and maxhops of 15:
DGS–3426:5#config stp maxage 18 maxhops 15 Command: config stp maxage 18 maxhops 15
Success.
DGS–3426:5#
config stp ports
Purpose Used to setup STP on the port level. Syntax
Description This command is used to create and configure STP for a group of ports. Parameters
config stp ports <portlist> {externalCost [auto | <value 1-200000000>] |hellotime <value 1-10> | migrate [yes|no] |edge [true|false|auto]| p2p [true|false|auto] |state [enable|disable]| restricted_role [true|false] |restricted _tcn [true|false]|lbd [enable|disable]|fbpdu [enable|disable]} (1)
<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 separate d 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. Non–contiguous portlist entries are separated by a comma. (ex: 1:1–1:3,1:7–1:9)
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 b y 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. If the value is more than 2, the hellotime will be 2.
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 | auto] true designates the port as an edge port. Edge ports cannot create
85
Page 90
xStack® DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
config stp ports
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. auto allows the port to have edge status whenever possible and operate as if the edge status were true. In auto mode, the bridge will delay for a period of time to become edge port if no bridge BPDU is received.
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 forced to half–duplex operation) the p2p status changes to operate as if the p2p value were false. The default setting for this parameter is
auto. state [enable | disable] Allows STP to be enabled or disabled for the ports specified in the
port list. The default is enable. restricted_role [ true | false ] –To decide if this port will be selected as the Root Port. The
default value is false. restricted_tcn [ true | false ] –To decide if this port not to propagate topology change. The
default value is false. lbd [enable | disable] – When this is enabled, the Switch will temporarily block STP on the port
when a BDPU packet has been looped back. If the Switch detects its own BDPU packet coming back, it signifies a loop on the network. STP will automatically be blocked and an alert will be sent to the administrator. The default is disable.
fbpdu [enable | disable] – Enabling this parameter will allow the forwarding of STP BPDU from other network devices when STP is disabled on the port. The default is disable.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To configure STP with path cost 19, hellotime set to 5 seconds, migration enable, and state enable for ports 1–5 of module 1.
DGS–3426:5#config stp ports 1:1–1:5 externalCost 19 hellotime 5 migrate yes state enable

config stp priority
Purpose Used to update the STP instance configuration Syntax
config stp priority <value 0–61440> instance_id <value 0–15>
Description This command is used to update the STP instance configuration settings on the Switch.
The MSTP will utilize the priority in selecting the root bridge, root port and designated port. Assigning higher priorities to STP regions will instruct the Switch to give precedence to the selected instance_id for forwarding packets. The lower the priority value set, the higher the priority.
Parameters priority <value 0–61440> – Select a value between 0 and 61440 to specify the priority for
a specified instance id for forwarding packets. The lower the value, the higher the priority. This entry must be divisible by 4096.
instance_id <value 0–15> – Enter the value corresponding to the previously configured instance id of which the user wishes to set the priority value. An instance id of 0 denotes the default instance_id (CIST) internally set on the Switch.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage: To set the priority value for instance_id 2 as 4096:

In instances where the priority value is identical, the MSTP function will implement the lowest port number into the forwarding state and other interfaces will be blocked. Remember that lower priority values mean higher priorities for forwarding packets.
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. Non–contiguous portlist entries are separated by a comma. (ex: 1:1–1:3,1:7–1:9)
instance_id <value 0–15> – Enter a numerical value between 0 and 15 to identify the instance_id previously configured on the Switch. An entry of 0 will denote the CIST
(Common and Internal Spanning Tree). internalCost – This parameter is set to represent the relative cost of forwarding packets to
specified ports when an interface is selected within a STP instance. The default setting is auto. There are two options:
auto – Selecting this parameter for the internalCost will set quickest route automatically and optimally for an interface. The default value is derived from the media speed of the interface.
value 1–200000000 – Selecting this parameter with a value in the range of 1– 200000000 will set the quickest route when a loop occurs. A lower internalCost represents a quicker transmission.
priority <value 0–240> – Enter a value between 0 and 240 to set the priority for the port interface. A higher priority will designate the interface to forward packets first. A lower number denotes a higher priority.
Restrictions Only Administrator and Operator-level users can issue this command.

config fdb aging_time
Purpose Used to set the aging time of the forwarding database. Syntax Description The aging time affects the learning process of the Switch. Dynamic forwarding table
Parameters
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To set the FDB aging time:
DGS–3426:5#config fdb aging_time 300 Command: config fdb aging_time 300
Success.
DGS–3426:5#
config fdb aging_time <sec 10–1000000>
entries, which are made up of the source MAC addresses and their associated port numbers, are deleted from the table if they are not accessed within the aging time. The aging time can be from 10 to 1000000 seconds with a default value of 300 seconds. A very long aging time can result in dynamic forwarding table entries that are out–of–date or no longer exist. This may cause incorrect packet forwarding decisions by the Switch. If the aging time is too short however, many entries may be aged out too soon. This will result in a high percentage of received packets whose source addresses cannot be found in the forwarding table, in which case the Switch will broadcast the packet to all ports, negating many of the benefits of having a switch.
<sec 10–1000000> − The aging time for the MAC address forwarding database value. The value in seconds may be between 10 and 1000000 seconds.
delete fdb
Purpose Used to delete an entry to the Switch’s forwarding database. Syntax Description This command is used to delete a previous entry to the Switch’s MAC address forwarding
Parameters
Restrictions Only Administrator and Operator-level users can issue this command.
