7. QoS Setting

Quality of Service (QoS) prioritizes network traffic and manages available bandwidth so that

the most important traffic goes first. QoS is implemented as rules or policies that prioritize

packets, optionally change information in the packet header, and assign them to outbound port

queues based on their priority.

7.1 Priority Mode

Each switch port has four types of outbound traffic queues based on priority: First-In-First-Out,

All-High-before-Low and Weight-Round-Robin.

The queue priority determines the order of exit for packets in the queue. For example, packets

in a high priority queue leave the switch before packets in other queues.

Please click QoS Setting Priority Mode

There are three Priority Modes to select.

 First-in-First-Out: The first receiving packet will be firstly transmitted.

 All-High-before-Low: All packets will be assigned to either Q2 (high) piority queue or Q1

(low) priority queue.

 Weight-Round-Robin: set the ratio of the transmitting packet for the low priority to high

priority.

When the queue weight is set to "0", it will be treated as "8"

The "low wieght" and "high weight" means the ratio of the packet in the

transmit queue. For example,

If "low weight" and "high weight" are set to "3" and "5", the ratio of the

trasmit packet for the low priority to high priority is 3/5.

7.2 Class of Service

You can set QoS mode of per port by different bases.

Please click QoS Setting Port, 802.1p, IP/DS based

As long as any of three COS schemes(802.1p,IP TOS/DS or Port Base) is mapped to "high",

the data packet will be treated as the high priority.

Enable is High Priority

7.3 Class of Service Configuration

Please click QoS Setting TCP/UDP Port Based

Base on different protocol, you can choose four different types of Class of Service for each

TCP/UDP port number -First-in-First-out, Discard, High Priority or Law Priority to control the

incoming packet.

The Class of Service for TCP/UDP port number allows the network administrator to assign the

specific application to a priotity queue.

 F-I-F-O: The incoming packet will be forwared in first-in-first-out scheme.

 Discard: The incoming packet will be discarded at the source port.

 High: The incoming packet will be forwareded with the high priority.

 Low: The incoming packet will be forwareded with the Low priority.

 The mask defines which bit is ignored within the IP address bit 0 ~ bit 7.

For example, UDP/TCP port = 65535 and mask = 5,this means 65530, 65531, 65534 and

65535 are all taken into account. UDP/TCP port =65535 and mask=0, this means only

65535 is taken into account.

 TCP/UDP Port QoS function: When the "override" item is selected, the Port_based,

Tag_based, IP TOS_based, CoS listed above will be ignored.

Click “Save” to confirm and finish the setting.

8. Security

8.1 MAC address Binding

Set special MAC address to activate on the selected port

Please click Security  MAC Address Binding

If you setting and enable the binding MAC address in access control list, The port only allow

MAC address on the access control list.

The single port you can setting three MAC address.

 MAC Address: Enter MAC address

 Select: Select Port to binding MAC address(you can select 1~26 port)

 Binding: [Enable] Allow the packet with the specified source MAC address to enter this

port.

8.2 Service Protocol Filter

You can enable or disable this function of per port.

Please click Security  Service Protocol Filter

 Function: setting Disable / Enable the function.

 Port Filtering Rule: The outgoing packet with selected protocol will be either forwarded or

dropped at secure WAN port as the figure shown below.

 "negative" means the selected protocol will be dropped and other protocols will be

forwarded.

 "positive" means the selected protocol will be forwarded and other protocol will be

dropped.

 Protocol: choose protocols which you want.

 Secure WAN Port: choose secure ports which you want.

1. The secure WAN port should be set at the physical port which is

connected to the server.

2. Once this function is enabled, the switch will check the destination

TCP/UTP port number at the outgoing direction of the secure WAN port.

** If the condition matches, this packet will be dropped or forwarded.

3. The description of Secure WAN port is shown on the bottom of this

screen.

Click “Save” to confirm and finish the setting.

9. Spanning Tree

Spanning Tree Protocol(STP) allows only one active path at a time between any two network

devices (this prevents the loops) but establishes the redundant links as a backup if the initial link

should fail. If STP costs change, or if one network segment in the STP becomes unreachable, the

spanning tree algorithm reconfigures the spanning tree topology and reestablishes the link by

activating the standby path. Without spanning tree in place, it is possible that both connections

may be simultaneously live, which could result in an endless loop of traffic on the LAN.

9.1 STP Bridge Settings

This setting is to avoid the loop network.

Please click Spanning Tree  STP Bridge Setting

 STP Mode: choose “Disable”, “STP” or “RSTP”

 Bridge Priority: Set the priority of the Bridge.

 Hello Time: Provides the time period between root bridge configuration messages.

 Max Age: Indicates when the current configuration message should be deleted.

 Forward Delay: Provides the length of time that bridges should wait before transitioning

to a new state after a topology change. (If a bridge transitions too soon, not all network

links might be ready to change their state, and loops can result.)

Click “Save” to confirm and finish the setting.

9.2 STP Port Setting

Please click Spanning Tree  STP Port Setting

 Port No.: Choose Port 1 ~ Port 26

 Priority: Setting 0~ 240

 RPC: The RPC= Root Path Cost: 0 = AUTO. When the loop is found, the STP/RSTP will

calculate the cost of its path.

STP Port Status

10. Trunking (Link aggregation)

Link aggregation can aggregate multiple Ethernet ports together to form a logical aggregation

group. To upper layer entities, all the physical links in an aggregation group are a single logical

link.

Link aggregation is designed to increase bandwidth by implementing outgoing/incoming load

sharing among the member ports in an aggregation group. Link aggregation group also allows for

port redundancy, which improves connection reliability.

Please click Trunking  Link Aggregation Setting

There are two groups to choose and each group is 4 ports and the third group is for 2 ports.

This standard describes the Link Aggregation Control Protocol (LACP), a mechanism for allowing

ports on both sides of a redundant link to configure themselves into a trunk link (aggregate link),

without the need for manual configuration of the ports into trunk groups.

When you enable link aggregation on a group of Brocade ports, the Brocade ports can negotiate

with the ports at the remote ends of the links to establish trunk groups.

 Member: Choose link group port.

 State: Choose Enable / Disable the link group function.
 Type: The IEEE 802.3ad Link Aggregation Control Protocol (LACP) enables the dynamic

aggregation of physical links and The Link Aggregation Control Protocol (LACP) is defined in

IEEE 802.3ad. It uses link aggregation control protocol data units (LACPDUs) for information

exchange between LACP-enabled devices. With the usage of preserved fields in LACPDUs,

LACP can deliver extended functions in addition to its basic functions.

 Static: switch and switch between must be fixed and setting Link Aggregation

Group(LAG) function.

 LACP: switch sides set to LACP mode, The ports on the switch through asking way to

check whether to join LAG, If there to join LAG, LACP connection can be achieved,

otherwise they skipped LACP connection.

 Activity: Both switches use “LACP” to configure the Trunk, at least one of them should be

“Active”.
 Active：Set the port in this category will take the initiative to ask link port whether the

LACP trunk. If yes, Join the Manage Connections in LACP

 Passive：The main can reply to active, and passive connectivity to reach LA CP.

11. DHCP Relay Agent

11.1 DHCP Relay Agent

Since DHCP clients request IP addresses via broadcast messages, the DHCP server and

clients must be on the same subnet. Therefore, a DHCP server must be available on each

subnet. It is not practical.

DHCP relay agent solves the problem. Via a relay agent, DHCP clients communicate with a

DHCP server on another subnet to obtain configuration parameters. Thus, DHCP clients on

different subnets can contact the same DHCP server for ease of centralized management and

cost reduction.

Please click DHCP Relay Agent  DHCP Relay Agent

 DHCP Relay State: Select DHCP Relay function Disable or Enable.
 DHCP Relay Hops Count Limit (1-16): The maximum numbers of DHCP relay agents

that will handle DHCP relayed traffic. The maximum value is 16 hops.

 DHCP Relay Option 82 State: The DHCP Information option (Option 82) is commonly

used in metro or large enterprise deployments to provide additional information on
“physical attachment” of the client. Option 82 is supposed to be used in distributed DHCP
server/relay environment, where relays insert additional information to identify the client’s
point of attachment. You can select the function Disable or Enable.

Click “Save” to confirm and finish the setting.

Your DHCP server must be configured to accept DHCP option 82. If the

server is not configured for DHCP option 82, the server does not use the

DHCP option 82 information in the requests sent to it when it formulates its

reply messages

11.2 Relay Server

Enter DHCP Server IP address. Please click DHCP Relay Agent  Relay Server

Click “Save” to confirm and finish the setting.

11.3 VLAN MAP Relay Agent

13. Other Setting

The function you can setting Aging time / VLAN Striding / and IGMP Snooping etc.

Please click Other Setting

 Output Queue Aging Time: Choose Aging time is 200/400/600/800ms or disable etc. The

output queue aging function allows the administrator to select the aging time of a packet

stored in the output queue. A packet stored in the output queue for a long time will lower the

free packet buffer, resulting in the poor utilization of the buffer and the poor switch

performance.

 VLAN Striding: You can choose VLAN Striding disable or enable function. When this

function is enabled, the switch will forward a uni-cast packet to the destination port. No matter

whether the destination port is in the same VLAN group.

 IGMP Snooping V1 & V2: You can choose IGMP Snooping disable or enable function. After

enable IGMP, will use both V1 and V2 function. If enable IGMP Snooping function, you can

choose disable or enable the IGMP Leave Packet. Mainly allows Leave packet will be

forwarded to IGMP router ports.

 VLAN Uplink Setting: Set “uplink1 or uplink2” or “Clear uplink1” or “Clear uplink2”

Click “Save” to confirm and finish the setting.
