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.

8

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

z System 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.

z Hello Time -- the time interval (seconds) between Spanning-Tree Protocol configuration

messages transmitting. Enter a value between 1 and 10, default value is 2.

z Max 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.

z Forward 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.

z Force Version – normal: use RSTP; compatible: compatible with old STP protocol

Port Configuration

z Aggregations – Enable/disable the RSTP protocol on aggregation links.

z Protocol Enabled – Enable/disable the RSTP protocol per port basis.

z Edge – Enable/disable a port to be an edge port (connect to an end station).

z Path 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.

20

2.1.11 IGMP

This switch provides IGMP snooping feature to detect IGMP queries and report packets. This feature

can limit the forwarding of multicast frames to certain ports that are members of multicast group.

Only IPv4 IGMP frames are recognized for this system.

The following parameters are provided for configuring IGMP snooping for this system:

 IGMP Enabled – enable/disable IGMP snooping function globally.

 Router Ports – specify administrative router ports for IGMP frames.

 Unregistered IPMC Flooding Enabled – set forwarding option of unregistered (not joined) IP

multicast traffic. Enabled: flood frames; Disabled: forward frames to router ports only.

Two options can be set for each existing VLAN group:

 IGMP Snooping Enabled – enable/disable snooping IGMP frames on this VLAN.

 IGMP Querying Enabled – enable/disable sending IGMP querying frames on this VLAN.

21

2.1.12 802.1x

Before you enable the 802.1x function, contact the administrator of RADIUS server to get IP address,

UDP port number and secret.

22

2.1.13 PoE status and command operation
