3.2.2 Ports
Port Security ensures access to a switch port based on MAC address, limits the
total number of devices from using a switch port, and protects against MAC
flooding attacks.
3.2.2.1 Port Configuration
In Port Configuration, you can set and view the operation mode for each port.
• Enable Jumbo Frames: This switch provides more efficient throughput for large
sequential data transfers by supporting jumbo frames on Gigabit Ethernet ports
up to 9.6 KB. Compared to standard Ethernet frames that run only up to 1.5 KB,
using jumbo frames significantly reduces the per-packet overhead required to
process protocol encapsulation fields.
• Power Saving Mode: Adjusts the power provided to ports based on the length
of the cable used to connect to other devices. Only sufficient power is used to
maintain connection requirements.
• Mode: Manually set the port speed such as auto, 10 half, 10 full, 100 half,
100 full, 1000 full. or disabled. Click on the “Apply” button to complete the
configuration.
Flow Control
Click the check box (x) to enable flow control. If flow control is set to enable, both
parties can send PAUSE frames to the transmitting device(s) if the receiving port is
too busy to handle the amount of data being sent. When it is set to disable, there
will be no flow control on that port. The port will drop packets if the amount of
data becomes too much for the port to handle.

Chapter 3: Software Description
3.2.3 VLAN
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allow you to isolate network traffic, so only the members of
the same VLAN will receive traffic from the members of the same VLAN.
Basically, creating a VLAN from a switch is logically equivalent to reconnecting a
group of network devices to another Layer 2 switch. However, all the network
devices are still plugged into the same switch physically.
3.2.3.1 Port Segmentation (VLAN) Configuration
• VLAN ID: ID of the configured VLAN (1–4096, no leading zeroes).
• VLAN Configuration List: Lists all the current VLAN groups created for this
system. Up to 16 VLAN groups can be defined. VLAN 1 is the default untagged
VLAN.
Figure 3-5.
3.2.3.2 VLAN Setup
The switch supports up to 16 VLANs based on 802.1Q standard. From the VLAN
Membership page you can create and delete VLANs, and change the VLAN port
membership.

3.2.3.3 VLAN Per Port Configuration
The 802.1Q Per Port Configuration page allows you to change the VLAN
parameters for individual ports or trunks. You can configure VLAN behavior for
specific interfaces, including the accepted frame types and default VLAN identifier
(PVID). Each row of the table corresponds to one port or trunk; trunked ports
cannot be configured individually; configure the trunk instead.

Chapter 3: Software Description
• Port/Trunk: The port number of the port or the ID of a trunk.
• VLAN Aware Enabled: VLAN aware ports are able to use VLAN tagged frames
to determine the destination VLAN of a frame. (Default: Enabled)
• VLAN aware ports will strip the VLAN tag from received frames and insert the
tag in transmitted frames (except for the PVID). VLAN unaware ports will not
strip the tag from received frames or insert the tag in transmitted frames.
• Ingress Filtering Enabled: If enabled, incoming frames for VLANs that do not
include this ingress port in their member set will be discarded.
(Default: Disabled)
• Packet Type: Sets the interface to accept all frame types, including tagged or
untagged frames, or only tagged frames. (Default: All) If the Packet Type is set
to “All,” the port can accept incoming tagged and untagged packets. Any
received packets that are untagged are assigned to the default VLAN. Any
tagged packets will be dropped unless the port is a member of the VLAN identi-
fied by the VLAN tag in the packet. If the Packet Type is set to “Tagged Only,”
the port will drop untagged packets and will only receive tagged packets.
Tagged packets will be dropped unless the port is a member of the VLAN iden-
tified by the VLAN tag in the packet. Switches should be connected to each
other with the Packet Type set to “Tagged Only.”
• PVID: The PVID (Port VLAN ID) is associated with untagged, ingress packets. It is
assigned to untagged frames received on the specified interface. The PVID has
no effect on ports that have Packet Type set to “Tagged Only.” (Default PVID: 1)
It is not possible to remove a port from VLAN 1 unless its PVID has been
changed to something other than 1. Outgoing packets are tagged unless the
packet’s VLAN ID is the same as the PVID. When the PVID is set to “None,” all
outgoing packets are tagged.
NOTE: If you select “Tagged Only” mode for a port, we recommend setting the
PVID to “None” as the standard configuration.

Chapter 3: Software Description
3.2.4 Aggregation
Port trunk allows multiple links to be bundled together and act as a single physical
link for increased throughput. It provides load balancing, and redundancy of links
in a switched inter-network. Actually, the link does not have an inherent total
bandwidth equal to the sum of its component physical links. Traffic in a trunk is
distributed across an individual link within the trunk in a deterministic method that
called a hash algorithm. The hash algorithm automatically applies load balancing
to the ports in the trunk. A port failure within the trunk group causes the
network traffic to be directed to the remaining ports. Load balancing is
maintained whenever a link in a trunk is lost or returned to service.
3.2.4.1 Aggregation / Trunking Configuration
To assign a port to a trunk, click the required trunk number, and then click
“Apply.”
Figure 3-8. Aggregation/trunking configuration screen.
3.2.5 LACP
IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by
automatically aggregating several physical links together as a logical trunk and
providing load balancing and fault tolerance for uplink connections.
3.2.5.1 LACP Port Configuration
• Port: The port number.
• Enabled: Enables LACP on the associated port.

Chapter 3: Software Description
• Key Value: Configures a port's LACP administration key. The port administrative
key must be set to the same value for ports that belong to the same link
aggregation group (LAG). If this administrative key is not set when an LAG is
formed (i.e., it has the null value of 0), this key will automatically be set to the
same value as that used by the LAG.
Figure 3-9. LACP port configuration screen.
3.2.6 RSTP
IEEE 802.1w Rapid Spanning tree protocol (LACP) provides a loop-free network
and redundant links to the core network with rapid convergence to ensure faster
recovery from failed links, enhancing overall network stability and reliability.
3.2.6.1 RSTP System Configuration
• System Priority: This parameter configures the spanning tree priority globally for
this switch. The device with the highest priority becomes the STP root device.
However, if all devices have the same priority, the device with the lowest MAC
address will then become the root device.
• Hello Time: Interval (in seconds) at which the root device transmits a
configuration message (BPDU frame). Number between 1–10 (default is 2).
• Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. This also means the
maximum life time for a BPDU frame. Number between 6–40 (default is 20).

Chapter 3: Software Description
• Forward Delay: The maximum time (in seconds) the root device will wait before
changing states (i.e., discarding to learning to forwarding). Number between
4–30 (default is 15).
• Force Version: Set and show the RSTP protocol to use. Normal - use RSTP,
Compatible—compatible with STP.
Figure 3-10. RSTP system configuration.
3.2.6.2 RSTP Port Configuration
• Port: The port ID. It cannot be changed. Aggregations mean any configured
trunk group.
• Enabled: Click on the tick-box to enable/disable the RSTP protocol for the port.
• Edge: Expect the port to be an edge port (linking to an end station) or a link to
another STP device.
• Path Cost: This parameter is used by the STP to determine the best path
between devices. Therefore, lower values should be assigned to ports attached
to faster media, and higher values assigned to ports with slower media. Set the
RSTP pathcost on the port. Number between 0–200000000. 0 means auto
generated pathcost.

Chapter 3: Software Description
3.2.7 IGMP Snooping
IGMP Snooping is the process of listening to IGMP network traffic. IGMP
Snooping, as implied by the name, is a feature that allows a layer 2 switch to
“listen in” on the IGMP conversation between hosts and routers by processing the
layer 3 IGMP packets sent in a multicast network.
When IGMP Snooping is enabled in a switch, it analyzes all IGMP packets
between hosts connected to the switch and multicast routers in the network.
When a switch hears an IGMP report from a host for a given multicast group, the
switch adds the host’s port number to the multicast list for that group. And,
when the switch hears an IGMP Leave, it removes the host’s port from the table
entry.
Prevents flooding of IP multicast traffic, and limits bandwidth intensive video
traffic to only the subscribers.
3.2.7.1 IGMP Configuration
• IGMP Enabled: When enabled, the switch will monitor network traffic to
determine which hosts want to receive multicast traffic.
• Router Ports: Set if ports are connecting to the IGMP administrative routers.
• Unregistered IPMC Flooding enabled: Set the forwarding mode for unregistered
(not joined) IP multicast traffic. The traffic will flood when enabled, and forward
to router-ports only when disabled.
• IGMP Snooping Enabled: When enabled, the port will monitor network traffic
to determine which hosts want to receive the multicast traffic.
• IGMP Querying Enabled: When enabled, the port can serve as the Querier,
which is responsible for asking hosts if they want to receive multicast traffic.

Chapter 3: Software Description
3.2.8 Mirroring
Port Mirroring is used on a network switch to send a copy of network packets
seen on one switch port (or an entire VLAN) to a network monitoring connection
on another switch port. This is commonly used for network appliances that
require monitoring of network traffic, such as an intrusion-detection system.
3.2.8.1 Mirroring Configuration
• Port to Mirror to: The port that will “duplicate” or “mirror” the traffic on the
source port. Only incoming packets can be mirrored. Packets will be dropped
when the available egress bandwidth is less than ingress bandwidth.
• Ports to Mirror: Select the ports that you want to mirror from this section of the
page. A port will be mirrored when the “Mirroring Enabled” check-box is
checked.

3.2.9 Quality of Service (QoS)
In QoS Mode, select QoS Disabled, 802.1p, or DSCP to configure the related
parameters.
3.2.9.1 QoS Configuration
• Strict: Services the egress queues in sequential order, transmitting all traffic in
the higher priority queues before servicing lower priority queues.
• WRR: Weighted Round-Robin shares bandwidth at the egress ports by using
scheduling weights with default values of 1, 2, 4, 8 for queues 0 through 7,
respectively. (This is the default selection.)
NOTE: WRR can only be selected if Jumbo Frame mode is disabled on the Port
Configuration page.

When the QoS Mode is set to QoS Disabled, the following table is displayed.
Figure 3-18. QoS disabled screen.
3.2.9.3 QoS Mode: 802.1p
Packets are prioritized using the 802.1p field in the VLAN tag. This field is three
bits long, representing the values 0–7. When the QoS Mode is set to 802.1p, the
802.1p Configuration table appears, allowing you to map each of the eight 802.1p
values to a local priority queue (low, normal, medium or high). The default set-
tings are shown below.
When the QoS Mode is set to 802.1p, the 802.1p Configuration table is displayed
as shown next.

3.2.9.4 QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code Point)
value. The Differentiated Services Code Point (DSCP) is a six-bit field that is
contained within an IP (TCP or UDP) header. The six bits allow the DSCP field to
take any value in the range 0–63. When QoS Mode is set to DSCP, the DSCP
Configuration table is displayed, allowing you to map each of the DSCP values to
a hardware output queue (low, normal, medium or high). The default settings
map all DSCP values to the high priority egress queue. Users can use the Prioritize
Traffic drop-down list to quickly set the values in the DSCP Configuration table to
a common priority queue. Use Custom if you want to set each value individually.
When the QoS Mode is set to DSCP, the DSCP Configuration table is displayed as
shown below.

3.2.10 Storm Control
Broadcast storms may occur when a device on your network is malfunctioning, or
if application programs are not well designed or properly configured. If there is
too much broadcast traffic on your network, performance can be severely
degraded or everything can come to complete halt.
You can protect your network from broadcast storms by setting a threshold for
broadcast traffic for each port. Any broadcast packets exceeding the specified
threshold will then be dropped.
3.2.10.1 Storm Control Configuration
There are three type of traffic that can be rate limited, including broadcast
multicast frame and Flooded Uncast Rate.
Figure 3-23.
• Enable Rate Limit: Click the check box to enable storm control.

Chapter 3: Software Description
• Rate (number of frames per second): The Rate field is set by a single drop-down
list. The same threshold is applied to every port on the switch. When the
threshold is exceeded, packets are dropped, irrespective of the flow-control
settings.
• Web: Click PORTS, Storm Control. This page enables you to set the broadcast
storm control parameters for every port on the switch.

• Hello Time: Interval (in seconds) at which the root device transmits a
configuration message.
• Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports (except
for designated ports) should receive configuration messages at regular intervals.
Any port that age out STA information (provided in the last configuration
message) becomes the designated port for the attached LAN. If it is a root port,
a new root port is selected from among the device ports attached to the
network.

Chapter 3: Software Description
• Fwd Delay: The maximum time (in seconds) the root device will wait before
changing states (i.e., discarding to learning to forwarding). This delay is required
because every device must receive information about topology changes before
it starts to forward frames. In addition, each port needs time to listen for
conflicting information that would make it return to a discarding state;
otherwise, temporary data loops might result.
• Topology: Indicates if spanning tree topology is steady or undergoing
reconfiguration. (The time required for reconfiguration is extremely short,
so no values other than “steady” state are likely to be seen in this field.)
• Root ID: The priority and MAC address of the device in the Spanning Tree that
this switch has accepted as the root device, and the port connected to the root
device.
3.3.4.2 RSTP Port Status

• Port/Group: The number of a port or the ID of a static trunk.
• Path Cost: The cost for a packet to travel from this port to the root in the
current Spanning Tree configuration. The slower the media, the higher the cost.
• Edge Port: Shows if this port is functioning as an edge port, either through
manual selection (see the RSTP Port Configuration table) or auto-detection.
NOTE: If the switch detects another bridge connected to this port, the manual
setting for Edge Port will be overridden, and the port will instead function
as a point-to-point connection.
