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.
The DES-3528/DES-3552 Series Layer 2 stackable Fast Et hernet Switch Ser ies are members of the D-Link xStack
®
family. Ranging from 10/100Mbps edge Switches to core gigabit Switches, the xStack Switch family has been futureproof designed to provide a stacking architecture with fault tolerance, flexibility, port density, robust security and
maximum throughput with a user-friendly management interface for the networking professional.
This manual provides a reference for all of the commands contained in the CLI for the xStack
®
DES-3528, DES3528P, DES-3528DC, DE S-3552 and DES-3552P s eries of Switches. Conf iguration and management of the Switch
via the Web-based management agent is discussed in the User’s Guide.
NOTE: For the remainder of this manual, all versions of the DES-3528, DES-3528P, DES-3528DC,
DES-3552 and DES-3552P Switches will be referred to as simply the Switch or the DES-3528/52
Series.
Accessing the Switch via the Serial Por t
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 are 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 − DES-
3528:admin# . 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 m anager
or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. Users 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 addres s 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 Switc h must be set before it can be managed with t he Web-based manager. The Switch I P
address can be autom aticall y set using BO OTP or DH CP protoc ols, in whic h case the actual a ddress as signed to th e
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. W her e the x’s r epresent the IP addres s to be assigned to the IP int erface
named System and the y’s represent the corresponding subnet mask.
2. Alternatively, users can enter conf ig ipif System ipa ddress xxx.xxx.x xx.xxx/z. Where the x’s represent the
IP address to be as sig ned t o the IP i nterfac e nam ed System and the z represents the cor respon ding num ber
of subnets in CIDR notation.
The IP interface nam ed System on the Switch can be assigned an IP address and s ubnet mask which can then be
used to connect a management station to the Switch’s Telnet or Web-based management agent.
DES-3528:admin# config ipif System ipaddress 10.24.73.21/8
Command: config ipif System ipaddress 10.24.73.21/8
Success.
DES-3528:admin#
Figure 1-3. Assigning an IP Address screen
In the above exam ple, the Switch was assigned an IP address of 10.24. 73.21 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, S NMP MIB browser and the CLI or via the W eb-based management agent using t he above
IP address to connect to the Switch.

USING THE CONSOLE CLI
The DES-3528/52 Series 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 re loa ded when the S witc h 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 Switc h to a VT100-compatible terminal or a computer runni ng an
ordinary terminal em ulator program (e.g., the HyperTerminal program included with the W indows 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 can also access the same functions over a Telnet interface. Once users have set an IP address for your Switch,
users 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 users have logged in, the console looks like this:

Figure 2-2. The ? Command
When users enter a command without its required parameters, the CLI will prompt users with a Next possible
completions: message.
DES-3528:admin# config account
Command: config account
Next possible completions:
<username>
DES-3528:admin#
Figure 2-3. Example Command Parameter Help
In this case, the comm and config account was entered with the parameter <username>. The CLI will then prompt
users to enter the <username> with the m essage, Next possible completions:. Every command in the CLI has this
feature, and complex commands have several layers of parameter prompting.
In addition, after typing an y given comm and plus one space, users can see all of the next possib le sub-c omm ands, in
sequential order, by repeatedly pressing the Tab key.
To re-enter the previous command at the comm and prompt, press the up arro w cursor key. The previou s command
will appear at the command prompt.

Figure 2-4. Using the Up Arrow to Re-enter a Command
In the above example, the comm and config account was entered without the requ ired parameter <username>, the
CLI returned the Next possible completions: <username> prompt. The up arrow cursor contr ol key was pres sed to
re-enter the previous comm and (config account) at the command prompt. Now the appropriat e 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 parameters.
If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed under the
Available commands: prompt.

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 Spann ing Tree Protocol, or MSTP, is a st andard defined b y the IEEE comm unity that allows m ultiple
VLANs to be m apped to a single spanning tre e instance, which will prov ide multiple pathways acros s the network.
Therefore, these MSTP c onfigurations will balance the traf fic load, preventing wide scale disrupti ons when a single
spanning tree instanc e fails. This will al low for faster c onvergences of ne w topologies f or the failed instanc e. 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 c lass if ie d by an instance_id. MST P wil l con nec t multiple spanning trees w ith a Com mon
and Internal Spann ing Tree (CIST ). The CIST will automatic ally determine each MSTP re gion, its max imum possible
extent and will appear as one virtual bridge that runs a single spanning tree. Consequentiall y, fram es assigned to
different VLANs will fol low different data ro utes within adm inistratively establish ed regions on the n etwork, continui ng
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 alphanum eric string of up to 32 characters (def ined 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 (def ined here as a vid_range) which will associate eac h 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.

DES-3528:admin# config stp version mstp
Command: config stp version mstp
Success
DES-3528:admin#
config stp
Purpose
Used to setup STP, RSTP and MSTP on the Switch.
Syntax config stp {maxage <value 6-40> | maxhops <value 6-40> | hellotime <value 1-2> |
forwarddelay <value 4-30> | txholdcount <val u e 1-10> | fbpdu [enable | disable] |
nni_bpdu_addr [dot1d | dot1ad]}(1)
Description
This command is used to setup the Spanning Tree Protocol (STP) for the entire Switch. All
commands here will be implemented for the STP version that is currently set on the Switch.
Parameters
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 deter mining
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
default value is 20.
maxhops <value 6-40> − 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 6 to 40. The default is 20.
hellotime <value 1-2> − The user may set the time interval between transmission of
configuration messages by the root device, thus stating that the Switch is still functioning. A
time between 1 and 2 seconds may be chosen, with a default setting of 2 seconds.
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 BPDU Hello packets transmitted per
interval. Default value is 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 disabled.
NOTE:
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 A dministrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure STP with maxage 18 and maxhops of 15:
DES-3528:admin# config stp maxage 18 maxhops 15
Command: config stp maxage 18 maxhops 15
Success.

config stp ports
Purpose
Used to setup STP on the port level.
Syntax config stp ports <portlis t> { externalCost [ auto | <value 1-200000000> ] | hellotime
<value 1-2> | migrate [yes | no ] | edge [ true | false | auto ] | p2p [ true | false | auto ] |
state [enable | disable ] | restricted_role [true | false] | restricted_tcn [true | false ] |
fbpdu [enable | disable ] }(1)
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.
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 1-2> − 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 2 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 | auto] – 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.
auto – Indicates that the port will be able to automatically enable the edge port status if this
port links to an end station or a device that does not support the STP function. The default
setting for this parameter is false.
restricted_role [true | false] – If true causes the Port not to be selected as Root Port for the
CIST or any MSTI, even it has the best spanning tree priority vector. Such a Port will be
selected as an Alternate Port after the Root Port has been selected. This parameter should
be false by default. If set, it can cause lack of spanning tree connectivity. It is set by a
network administrator to prevent bridges external to a core region of the network influencing
the spanning tree active topology, possibly because those bridges are not under the full
control of the administrator. The default setting for this parameter is false.
restricted_tcn [true | false] – If true causes the Port not to propagate received topology
change notifications and topology changes to other Ports. This parameter should be false by
default. If set it can cause temporary loss of connectivity after changes in a spanning trees
active topology as a result of persistent incorr ectly learned station location inform ation. It is
set by a network administrator to prevent bridges external to a core region of the network,
causing address flushing in that region, pos sib l y becau s e those bridges are not under the full
control of the administrator or MAC_Operational for the attached LANs transitions frequently.
The default setting for this parameter is false.
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 fullduplex. 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
Page 80

80
config stp ports
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.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command
Example usage:
To configure STP with path cost 19, hellotime set to 2 seconds, migration enabled, and state enabled for ports
1-5 of module 1.
DES-3528:admin# config stp ports 1-5 externalCost 19 hellotime 2 migrate yes state
enable
Command: config stp ports 1-5 externalCost 19 hellotime 2 migrate yes state enable
Success.
DES-3528:admin#
create stp instance_id
Purpose
Used to create a STP instance ID for MSTP.
Syntax create stp instance_id <value 1-15>
Description
This command allows the user to create a STP instance ID for the Multiple Spanning Tree
Protocol. There are 16 STP instances on the Switch (one internal CIST, unchangeable) and
the user may create up to 15 instance IDs for the Switch.
Parameters
<value 1-15> − Enter a value between 1 and 15 to identify the Spanning Tree instance on the

Syntax config stp instance_id <value 1-15> [add_vlan | remove_vlan] <vidlist>
Description
This command is used to map VIDs (VLAN IDs) to previously configured STP instances on
the Switch by creating an instance_id. A STP instance may have multiple members with the
same MSTP configuration. There is no limit to the number of STP regions in a network but
each region only supports a maximum of 16 spanning tree instances (one unchangeable
default entry). VIDs can belong to only one spanning tree instance at a time.
NOTE:
Switches in the same spanning tree region having the same STP
instance_id must be mapped identically, and have the same configuration
revision_level number and the same name.
Parameters
<value 1-15> − Enter a number between 1 and 15 to define the instance_id. The Switch

config fdb aging_time
Purpose
Used to set the aging time of the forwarding database.
Syntax config fdb aging_time <sec 10-1000000>
Description
The aging time affects the learning process of the Switch. Dynamic forwarding table 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.
Parameters
<sec 10-1000000> − The aging time for the MAC address forwarding database value. The
value in seconds may be between 10 and 1000000 seconds.

TRAFFIC CONTROL COMMANDS
On a computer networ k, packets such as Multic ast packets and Broadcas t packets continuall y flood the network as
normal procedure. At tim es, this traffic m ay increase do to a malicio us endstation on the network or a m alfunctioning
device, such as a fault y net wor k card. Thus, Switch throughput pr oblem s will aris e and cons eque ntl y affec t the overal l
performance of the Switch network. To help rectify this packet storm, the Switch will monitor and control the situation.
The packet storm is m onitored t o det er mine if too many packets are f loodin g the n et work, based on the threshold leve l
provided by the user. Once a packet storm has been detected, the S witch will drop over flow packets coming into the
Switch until the storm has subsided. This method can be utilized by selecting the Drop option of the Action field in the
window bel ow.
The Switch will also scan and monitor p ackets coming into th e Switch by monitoring the Switch’s chip c ounter. This
method is only viable for Broadcast and Multicast s torms because the ch ip only has counters f or these two types of
packets. Once a storm has been detected (that is, once the packet threshold set below has been exceeded), the
Switch will shutdown the port to all incoming traffic with the exception of STP BPDU packets, for a time period
specified using the countdown field. If the p acket s torm dis continues b efore th e countd own tim er expires, the por t will
again allow all incoming traffic. If this field times out and the packet storm continues, the port will be placed in a
Shutdown Forever mode which will produce a w arning message to be s ent to the Trap Receiver, if we have set the
trap field. Once in Shutdow n Forever m ode, the port will be reco vered autom aticall y, when the auto-recover time has
expired. (If the value was set to “0”, the port will not be auto recover ed), or the user manual ly resets the p ort us ing the
config ports enable command, mentioned previously in this manual.
The broadcast storm control commands in the Command Line Interface (CL I) are listed (along wit h the appropriate
parameters) in the following table.

config traffic control
Purpose
Used to configure broadcast/multicast/unicast packet storm control. The software mechanism
is provided to monitor the traffic rate in addition to the hardware storm control mechanism
previously provided.
Syntax config traffic control [<portlist> | all] {broadcast [enable | disable] | multicast [enable |
disable] | unicast [enable | disable] | action [drop | shutdown] | threshold <value 0255000> | countdown [<min 0> | <min 3-30> | disable] | time_interval <sec 5-600>}
Description
This command is used to configure broadcast/multicast/unicast storm control. By adding the
new software traffic control mechanism, the user can now use both a hardware and software
mechanism, the latter of which will now provide shutdown, recovery and trap notification
functions for the Switch.
Parameters
<portlist> − Used to specify a group list of ports to be configured for traffic control, as defined
below:
all − Specifies all portlists are to be configured for traffic control on the Switch.
broadcast [enable | disable] − Enables or disables broadcast storm control.
multicast [enable | disable] − Enables or disables multicast storm control.
unicast [enable | disable] − Enables or disables unicast traffic control.
action – Used to configure the action taken when a storm control has been detected on the

config traffic control
Switch. The user has two options:
• drop − Utilizes the hardware Traffic Control mechanism, which means the Switch’s
hardware will determine the Packet Storm based on the Threshold value stated
and drop packets until the issue is resolved.
• shutdown − Utilizes the Switch’s software Traffic Control mechanism to determine
the Packet Storm occurring. Once detected, the port will deny all incoming traffic to
the port except STP BPDU packets, which are essential in keeping the Spanning
Tree operational on the Switch. If the countdown timer has expired and yet the
Packet Storm continues, the port will be placed in Shutdown Forever mode. The
port will be recovered automatically, when the auto-recover time has expired. (If the
value was set to “0”, the port will not be auto recovered), or the user manually
resets the port using the config ports enable command. Choosing this option
obligates the user to configure the time_interval field as well, wh ic h wil l provide
packet count samplings from the Switch’s chip to determine if a Packet Storm is
occurring.
threshold <value 0-255000> − The upper threshold at which the specified traffic control is
Switched on. The <value> is the number of broadcast/multicast/unicast packets, in packets
per second (pps), received by the Switch that will trigger the storm traffic control measures.
The default setting is 131072.
time_interval − The Interval will set the time between Multicast and Broadcast packet counts
sent from the Switch’s chip to the Traffic Control function. These packet counts are the
determining factor in deciding when incoming packets exceed the Threshold value.
<sec 5-600> − The Interval may be set between 5 and 600 seconds with the default setting
of 5 seconds.
countdown − The countdown timer is set to determine the amount of time, in minutes, that
the Switch will wait before shutting down the port that is experiencing a traffic storm. The
Switch will shutdown the port only if the traffic level exceeds the previously configured
threshold all the time during this countdown period. This parameter is only useful for ports
configured as shutdown in the action field of this command and therefore will not operate
for Hardware based Traffic Control implementations.
• <min 0> - is the default setting for this field and 0 will denote that the port will never
enter shutdown forever mode.
• <min 3-30> – Select a time from 3 to 30 minutes that the Switch will wait before
shutting down. Once this time expires and the port is still experiencing packet
storms, the port will be placed in shutdown forever mode and the port will be
recovered automaticall y, when auto-recover time has expired, or be manually
recovered using the config ports command mentioned previously in this manual.
•
disable – Specifies that the port will enter shutdown forever at once.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure traffic control and enable broadcast storm control for ports 1-12:
DES-3528:admin# config traffic control 1-12 broadcast enable action shutdown threshold
1 countdown 10 time_interval 10
Command: config traffic control 1-12 broadcast enable action shutdown threshold 1
countdown 10 time_interval 10
Success.
DES-3528:admin#
config traffic control log state
Purpose
This command is used to configure the traffic control log state.
Syntax config traffic control log state [enable | disable]
Description
When the log state is enabled, traffic control states are logged when a storm occurs and
when a storm is cleared. If the log state is disabled, traffic control events are not logged.

config traffic control log state
Note: The log state is only applicable for shutdown mode. Since shutdown mode only
support broadcast and multicast storm control, doesn’t support unicast storm control. The log
only generate for broadcast and multicast storm control.
Parameters enable - Both occurred and cleared are logged.
disable - Neither occurred nor cleared is logged.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure the traffic log state on the Switch:
DES-3528:admin# config traffic control log state enable
Command: config traffic control log state enable
Success.
DES-3528:admin#
config traffic control auto_recover_time
Purpose
This command is used to configure the traffic auto recover time that allowed for a port to
recover from shutdown forever status.
Syntax config traffic control auto_recover_time [<min 0> | <min 1-65535>]
Description
This command is used to configure the traffic auto recover time that allowed for a port to
recover from shutdown forever status.
Parameters auto_recover_time - The time allowed for auto recovery from shutdown for a port. The default
value is 0, so no auto recovery is possible; the port remains in shutdown forever mode. This
requires manual entry of the CLI command “config ports [ <portlist> | all ] state enable" to
return the port to a forwarding state. The default value is 0, which means disable auto
recover mode, shutdown forever.
<min 0> - Specifies that the auto recovery time will be disabled.
<min 1-65535> - Enter the auto recovery time value here. This value must be between 1 and
65535.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure the auto recover time to 5 minutes:
DES-3528:admin# config traffic control auto_recover_time 5
Command: config traffic control auto_recover_time 5
Success.

QOS COMMANDS
The Switch supports 802.1p priority queuing. The Switch has 8 priority queues, but it has 7 priority queues available .
Q7 is reserved for stacking function. These priority queues are numbered from 6 (Class 6) — the highest priority
queue — to 0 (Class 0) — the lowest priority queue. The eight priority tags specified in IEEE 802.1p (p0 to p7) are
mapped to the Switch’s priority queues as follows:
• Priority 0 is assigned to the Switch’s Q2 queue.
• Priority 1 is assigned to the Switch’s Q0 queue.
• Priority 2 is assigned to the Switch’s Q1 queue.
• Priority 3 is assigned to the Switch’s Q3 queue.
• Priority 4 is assigned to the Switch’s Q4 queue.
• Priority 5 is assigned to the Switch’s Q5 queue.
• Priority 6 is assigned to the Switch’s Q6 queue.
• Priority 7 is assigned to the Switch’s Q6 queue.
• Q7 is reserved for stacking function.
Priority scheduling is implemented by the priority queues stated above. The Switch will empty the seven hardware
priority queues in order, beginning with the highest priority queue, 6, to the lowest priority queue, 0. Each hardware
queue will transmit all of the packets in its buffer before permitting the next lower priority to transmit its packets. When
the lowest hardware priority queue has finished transmitting all of its packets, the highest hardware priority queue will
begin transmitting any packets it may have received.
The commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.

config scheduling
Purpose
Used to configure the traffic scheduling mechanism for each CoS queue.
Syntax config scheduling {ports [<portlist> | all ]} <class_id 0-6> [strict | weight <value 1-
127>]
Description
The Switch contains seven hardware priority queues available. Incoming packets must be
mapped to one of these seven queues. This command is used to specify the rotation
mechanism regarding how packets in these seven hardware priotiry queues are being
handled and emptied.
The Switch’s default (if the config scheduling command is not used, or if the config
scheduling command is entered with weight parameters set to 0) is to empty the 7 hardware
priority queues in order − from the highest priority queue (hardware queue 6) to the lowest
priority queue (hardware queue 0). Each hardware queue will transmit all of the packets in its
buffer before allowing the next lower priority queue to transmit its packets. When the lowest
hardware priority queue has finished transmitting all of its packets, the highest hardware
priority queue can again transmit any packets it may have received.
The weight parameter allows the user to specify the maximum number of packets a given
hardware priority queue can transmit before allowing the next lower hardware priority queue
to begin transmitting its packets. A value between 0 and 127 can be specified. For example,
if a value of 3 is specified, then the highest hardware priority queue (number 6) will be
allowed to transmit 3 packets − then the next lower hardware priority queue (number 5) will
be allowed to transmit 3 packets, and so on, until all of the queues have transmitted 3
packets. The process will then repeat.
Parameters
<class_id 0-6> − Specifies which of the seven hardware priority queues that the config
scheduling command will apply to. The seven hardware priority queues are identified by
number, from 0 to 6, with the queue 0 being the lowest priority.
[<portlist> | all] − Specifes a range of ports to be configured.
strict – Specifies this queue is always working in strict mode.
weight <value 1-127> − Us i ng weighted fair algorithm to handle packets in priority queues.
Each queue will operate based on its setting of weight values.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure the traffic scheduling for each CoS queue:
