xStack® DES-3528/DES-3552 Series Layer 2 Fast Ethernet Managed Switc h CLI Reference Guide

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 Ethernet Switch Series 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 3528P, DES-3528DC, DE S-3552 and DES-3552P s eries of Switches. C onfiguration and managem ent 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 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 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 manager 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 Sw itch must be set before it can be managed w ith the Web-based manager. The S witch IP address can be autom aticall y set using BOOTP or D HCP pro tocols, in which cas e the actua l address as signed t o 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 repres ent the IP address to be assigned to the IP inter face named System and the y’s represent the corresponding subnet mask.

2. Alternatively, users can enter con fig ipif System ip address xxx.xxx.x xx.xxx/z. Where the x’s represent the IP address to be assig ned t o the IP i nterf ace n am ed System an d the z represents the corr espondi ng num ber of subnets in CIDR notation.

The IP interface nam ed 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.

Command: config ipif System ipaddress 10.24.73.21/8

Success.

Figure 1-3. Assigning an IP Address screen

In the above exam ple, the Switch w as assigned an IP address of 10.24 .73.21 with a sub net 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 bro wser and the CLI or via th e Web-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 reloa ded when t he Sw itch 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 em ulator program (e.g., the HyperTerminal program included with the W indows operating s ystem) 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.

Command: config account

Next possible completions: <username>

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 prom pt users to enter the <username> with the m ess age, Next possible completions:. Every command in the CL I has this feature, and complex commands have several layers of parameter prompting.

In addition, after typing an y given com mand plus one space, user s can see all of the next poss ible sub-commands, in sequential order, by repeatedly pressing the Tab key.

To re-enter the previo us command at the comm and prompt, press the up arr ow cursor key. The previ ous command will appear at the command prompt.

Command: config account Next possible completions: <username>

DES-3528:admin# config account Command: config account Next possible completions: <username>

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 cont rol ke y was pressed to re-enter the previous com mand (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.

auth_priv]] {read_view <view_name 32> | write_view <view_name 32> | notify_view <view_name 32>}(1)

This command creates a new SNMP group, or a table that maps SNMP users to SNMP views.

<groupname 32> − An alphanumeric name of up to 32 characters that will identify the SNMP group the new SNMP user will be associated wit h.

v1 – Specifies that SNMP version 1 will be used. The Simple Network Management Protocol (SNMP), version 1, is a network management protocol that provides a means to monitor and control network devices.

v2c – Specifies that SNMP version 2c will be used. The SNMP v2c supports both centralized and distributed network management strategies. It includes improvements in the Structure of Management Information (SMI) and adds some security features.

v3 – Specifies that the SNMP version 3 will be used. SNM P v3 prov ides secur e ac ces s to devices through a combination of authentication and encrypting packets over the network. SNMP v3 adds:

• 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 − Specifies that there will be no authorization and no encryption of packets 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.

read_view – Specifies that the SNMP group being created can request SNMP messages. write_view – Specifies that the SNM P gro up being cr e ated has writ e pr ivil eges. notify_view − Specifies that the SNMP group being created can receive SNMP trap

messages generated by the Switch’s SNMP agent. <view_name 32> − An alphanumeric string of up to 32 characters that is used to identify the

group of MIB objects that a remote SNMP manager is allowed to access on the Switch.

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 Protoc ol, or MSTP, is a s tandard defined b y the IEEE comm unity that allows multiple VLANs to be m apped to a single spanning tr ee instance, which will pr ovide multiple pathways acros s the network. Therefore, these MST P configurations will balance the traf fic load, preventing wide scale disru ptions when a single spanning tree instanc e fails. This will al low for faster convergences of n ew topologies f or the failed insta nce. 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 clas s if ied by an instance_id. MSTP will connect multiple spa nning trees with a Com mon and Internal Spann ing Tree (CIST ). The CIST will automat ically determine each MSTP re gion, its m aximum possible extent and will appear as one virtual bridge that runs a single spanning tree. Consequentially, frames assigned to different VLANs will fol low different data ro utes within adm inistratively estab lished regions on t he network, contin uing 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 ( defined here as a vid_range) which will assoc iate each of the possible 409 6 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.

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 < value 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 det ermining 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.

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 Spanni ng 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 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.

Restrictions

Only Administrator and Operator and Power-User-level users can issue this command.

Example usage:

To configure STP with maxage 18 and maxhops of 15:

Command: config stp maxage 18 maxhops 15

Success.

xStack® DES-3528/DES-3552 Series Layer 2 Fast Ethernet Managed Switc h CLI Reference Guide

config stp ports

Purpose Syntax config stp ports <portlist> { externalCost [ auto | <value 1-200000000> ] | hellotime

Description Parameters

Used to setup STP on the port level.

<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)

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

<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 ec tly 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 s ib ly beca u 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

xStack® DES-3528/DES-3552 Series Layer 2 Fast Ethernet Managed Switc h CLI Reference Guide

the port cannot maintain this status (for example if the port is forced to half-duplex operation)

config fdb aging_time

Purpose Syntax config fdb aging_time <sec 10-1000000> Description

Parameters

Restrictions

Example usage:

To set the FDB aging time:

Command: config fdb aging_time 300

Success.

Used to set the aging time of the forwarding database.

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.

<sec 10-1000000> − The aging time for the MAC address forwarding database value. The value in seconds may be between 10 and 1000000 seconds.

Only Administrator and Operator and Power-User-level users can issue this command

TRAFFIC CONTROL COMMANDS

On a computer net work, packets such as Mul ticast packets and Broadc ast packets continuall y flood the network as normal procedure. At tim es, this traffic may increase do to a m alicious endstation on the network or a m alfunctioning device, such as a fault y net w ork card. Thus, Switch throughput problem s will arise and c onse quentl y affec t the over all performance of the Switch network. To help rectify this packet storm, the Switch will monitor and control the situation.

The packet storm is monitored to determine if too m any packets are flooding the network, based on the threshold leve l provided by the user. Onc e a packet storm has been detected, th e Switch will drop o verflow 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 below.

The Switch will als o scan and monitor p ackets coming into th e Switch by monitoring the Switch’s chip c ounter. This method is only viable f or Broadcast and Multicas t storms 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 discontinues b efore th e countd own tim er expires, the port 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 m ode which will produce a warning message to be s ent to the Trap Receiver , if we have set th e trap field. Once in Shutdow n Forever m ode, the port will be rec overed autom aticall y, when the auto-recover time has expired. (If the value was s et to “0”, the port will not be auto recov ered), or the us er manual ly resets the port 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

Syntax config traffic contro l [<portlist> | all] {broadcast [enable | disable] | multicast [enable |

Description

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.

disable] | unicast [enable | disable] | action [drop | shutdown] | threshold <value 0255000> | countdown [<min 0> | <min 3-30> | disable] | time_interval <sec 5-600>}

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.

xStack® DES-3528/DES-3552 Series Layer 2 Fast Ethernet Managed Switc h CLI Reference Guide

Switch. The user has two options:

disable – Specifies that the port will enter shutdown forever at once.

DES-3528:admin# config traffic control 1-12 broadcast enable action shutdown threshold

DES-3528:admin#

config traffic control

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.

Restrictions

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.

Only Administrator and Operator and Power-User-level users can issue this command.

• 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 w il l pro vi d e packet count samplings from the Switch’s chip to determine if a Packet Storm is occurring.

• <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 aut o-recover time has expired, or be manually recovered using the config ports command mentioned previously in this manual.

•

Example usage:

To configure traffic control and enable broadcast storm control for ports 1-12:

1 countdown 10 time_interval 10 Command: config traffic control 1-12 broadcast enable action shutdown threshold 1 countdown 10 time_interval 10

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 per_queue bandwidth_control

Purpose

Syntax config per_queue bandwidth_con trol {ports [<portlist> | all ]} <cos_id_list 0-6>

Description

Parameters

Used to configure per port or flow bandwidth control. For per flow bandwidth control, it can be based on the assigned CoS queue.

{min_rate [no_limit | <value 64-1024000>] max_rate [no_limit | <value 64-1024000>]}(1)

This command is used to set per port or flow bandwidth control. For per flow bandwidth control, it can be based on the assigned CoS queue.

Mini-rate specifies the minimal quaranteed bandwidth. Specify no limit for the mini-rate means no quaranteed bandwidth.

Max-rate speficies the max-rate limitatoin. When it is specified, packet transmitted from the queue will not exceed the specified max-rate limitation even though there is still available bandwidth.

The specification of mini-rate and max-rate are effective regardless whether the queue is operated in the strict mode or in the wrr mode.

<portlist> − Specifies a port or range of ports to be configured. <cos_id_list 0-6> − Specifies a priority queue or range of priority queues to be configured. min_rate - Specifies one of the parameters below (no_limit or <value 64-1024000>) that will

be applied to the minimum rate at which the above specified class will be allowed to receive packets.

 no_limit − Specifies that there will be no limit on the rate of packets received by the

above specified class.

 <value 64-1024000> − Specifies the packet limit, in Kbps, that the above ports will

be transmit at least.

max_rate − Specifies one of the parameters below (no_limit or <value 64-1024000>) that will be applied to the maximum rate at which the above specified class will be allowed to transmit packets.

 no_limit − Specifies that there will be no limit on the rate of packets transmit by the

above specified class.

 <value 64-1024000> − Specifies the packet limit, in Kbps, that the above ports will

be transmit at most.

127>]

Description

Parameters

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.

<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> − Using weighted fair algorithm to handle packets in priority queues.

Each queue will operate based on its setting of weight values.
