1 Introduction
The NSH-9308P Switch is a high performance web-smart managed switch, which provides up to 8
10/100/1000Mbps copper Ethernet ports. This device provides a great flexibility for nowadays variety
of network application at lower cost. User doesn’t have to learn many sophisticated management
function which are usually shown in SNMP switch, but just need to learn some simple setting
procedures through either out-of-band RS232 port or in-band Ethernet port. However, some
advanced and important function such as Tag-based VLAN, Trunking, RSTP and IGMP are also
supported in this Switch. This means, user doesn’t have to pay high cost as tradition layer 2 SNMP
switches, when he wants to get advanced function to meet requirement of network application. This
makes the Switch very suitable for small or medium size company to build up simple network at
beginning phase with lower cost. Besides, an optional long-ear accessory also makes it possible to
operate in the rack mount environment.
The NSH-9308P Switch was designed to operate at non-blocking and line speed performance,
auto-negotiation and auto-MDI/MDIX function are also supported on all 10/100/1000Mbps RJ-45
Gigabit copper ports. No matter running with half or full duplex mode, these function make user easy
to use, and reduce the matching effort between straight and cross-over cable issues.
The NSH-9308P Switch supports both port-based and 802.1Q (tag-based) VLAN to catch-up the
application needed. To increase bandwidth application, it supports up to 4 trunk groups with
maximum 8 ports on one trunk, and these trunk ports are with fair-over function to provide redundant
link when one or more trunk ports were malfunction. In addition, Rapid STP (RSTP) and multicast
application IGMP were also supported at the software function. A reset button was provided to make
user easy to go back to default settings.

2.1 Configurations
2.1.1 System information
The system diagram shows common system information, they are H/W, F/W version, MAC address,
IP address, subnet mask, IP gateway, default VLAN value of management port, name, password,
timeout value, and SNMP communities…etc. Once you changed the settings, it’s needed to press
the “Apply“ button to implement these settings, and you can press the “Refresh“ button to get
updated status of system information.
2.1.1.1 DHCP
The default DHCP setting is disabled, so default IP address or user defined IP address was used
when powered on this switch. If this switch needs an IP address assigned by DHCP server, you
should check the square field and then press “Apply“ to implement. User must be aware that if DHCP
setting was enabled from web page, and the DHCP server is working, the connection will be lose,
7

because the IP address of this Switch has been changed.
2.1.1.2 Relocate HTTP port number
The default port number of HTTP access is 80, but unauthorized user may intrude this switch if he
knows the IP address of this switch. You may relocate this port number to other value, from 1024 to
65535. Once you change the port number of HTTP access and implement new setting, you will lost
current connection and you must access the Switch by new setting:
http://192.168.223.100:port_value
2.1.1.3 Tag VLAN management group
At first time you turn on this Switch, all ports belong to default VLAN ID group (VID=1), so they can
communicate to each other, and any port can be used as web management port to access this
Switch. But, for example, if you create VLAN ID=10 and assign port 7, 8 to this VLAN, then create
another VLAN ID = 20 and assign port 5, 6 to this VLAN, 3 VLAN groups will be shown on VALN
group table after you implement these settings. At this time, the management VLAN still remains on
VID=1 group, you can only perform web management through ports assigned to this VLAN (port 1, 2,
3, 4). If you want to perform web management from other port in existing different VLAN group, for
example port 8 in VID =10, you must go to system configuration page, and select Tag VLAN
Management Group to 10, then press “Apply“ to implement new setting. Therefore, you can perform
web management from ports assigned to management VLAN.
IF you forget the setting about management, there are two ways to solve this condition below.
(1) Through console port, change VLAN ID of management VLAN.
(2) Press “Reset” button few seconds, let system return to default settings.

2.1.2 Ports
Port status page always shows current port status of all 8 ports. User can set link mode, enable or
disable flow control and jumbo frame. However, be noticed that the jumbo frame is setting globally, it
can’t be set on one port individually. A default diagram is shown below,
9

2.1.3 Port-based VLAN
Port-based VLAN is a kind of VLAN, which is a group of ports marked by same group ID, different
VLAN (different ID) can’t communicate to each other.
A default diagram is shown below.
10

2.1.4 Tag-based VLAN
Tag-based VLAN is another kind of VLAN, which is a group of ports assigned to the same VLAN ID.
Different VLAN (different ID) can’t communicate to each other. By default, all ports of the switch were
belonged to same VLAN, which ID is 1 (VLAN ID=1).
A default diagram is shown below.
There are some attributes can be assigned for advanced tag-based VLAN application. Click “Port
Config“ button to modify these attributes.
11

1. VLAN Aware mode:
Enabled - Strip VLAN tag from received frame and insert VLAN tag in transmitted frame, except
ingress frames which’s VID is the same as PVID.
Disabled – Default state, switch doesn’t do VLAN tag stripping and inserting.
2. Ingress filtering:
Enabled - Check ingress frame VLAN ID. Ingress frame will be dropped if frame's VID is not the
same as the VID of the ingress port.
Disabled – Don’t do ingress VLAN frame checking, frames will be flood as normal.
3. Accept Packet Type:
ALL - Accept all ingress frames
Tagged only - Only accept ingress frames with VLAN tag
4. Port VID:
Set port VLAN ID for untagged ingress frames. Set "None" for trunk port member.
12

2.1.5 Port Trunking
Port Trunking defines how to create a single high-speed logical link that combines several low-speed
physical links. By default, all ports were set to normal state. You can group multiple ports to a trunk;
up to 4 groups are supported.
For example, choose port 1 and port 2 into group 1. After implementation, diagram will show as
below.
13

2.1.6 Port Mirroring
Set the port mirroring option to monitor data being transmitted through a specific port.
A default diagram is shown below.
Choose the association of ports you want to implement mirroring function. For example, choose port
2 to be monitored, and port 1 to monitor.
14

2.1.7 Quality of Service
QoS (Quality of Service) refers to the mechanisms in the Switch’s network software that make the
actual determinations of which packets have priority.
There are three QoS mode in the Switch: Port-based, 802.1p and DSCP.
15

16

2.1.8 Storm Control
Set storm control limitation to prevent abnormal traffic.
Choose frame types that you want to control, and select the limitation. For example, choose
Broadcast storm with 3,964 frames per second as upper limit, once the Broadcast frame rate higher
than 3,964 frames per second at any of the ports, the special port will be disabled.
17

2.1.9 LACP
Different from the static port trunking, LACP provides another way to aggregate ports to a group
(trunk) dynamically according to IEEE 802.3ad standard.
−Protocol Enabled – to enable/disable LACP protocol on a port.
−Key Value – a number (1~255) to identify the LACP group for a port. All member ports in a LACP
group have the same key values. Key value will be generated automatically if the value was set to
“auto”.
Choose and click the trunk ports you want to group. For example, select port 7 and port 8 to group
into a LACP group with key value 20 for both ports, then press “Apply” to implement the setting.
18

2.1.10 RSTP
The Spanning-Tree Protocol (STP) is IEEE 802.1d standardized method for avoiding loops in
switched networks. Enable STP to ensure that only one path at a time is active between any two
nodes on the network.
The Rapid-Spanning-Tree-Protocol (RSTP) is a more advanced protocol than STP according to
IEEE 802.1w standard. RSTP can shorten spanning tree convergent time while network topology is
changed.
19

You can modify the following parameters of RSTP function to accommodate your network.
System Configuration
zSystem Priority – A value to identify the root bridge. The bridge (switch) with lowest value has
the highest priority and will be selected as the root. 16 numbers are provided in this field from 0
to 61440 in increments of 4096, default value is 32768.
zHello Time -- the time interval (seconds) between Spanning-Tree Protocol configuration
messages transmitting. Enter a value between 1 and 10, default value is 2.
zMax Age – the time interval (seconds) bridge (switch) will wait before attempting to reset STP
parameters when missing Spanning-Tree Protocol configuration messages. Enter a value
between 6 and 40, default value is 20.
zForward Delay -- the time before bridge (switch) changes its ports from STP learning and
listening states to the forwarding state. Enter a value between 4 and 30, default value is 15.
zForce Version – normal: use RSTP; compatible: compatible with old STP protocol
Port Configuration
zAggregations – Enable/disable the RSTP protocol on aggregation links.
zProtocol Enabled – Enable/disable the RSTP protocol per port basis.
zEdge – Enable/disable a port to be an edge port (connect to an end station).
zPath Cost – A value on a port that switch uses to determine which port will be the forwarding
port, if there are more than one path to the root bridge. The port with lowest path cost will be the
forwarding port. The value can be set from 1 to 200000000 or “auto” to be automatically
generated.
