3.2 Web Management Overview

After you login, the switch shows you the system information as below. This page is default and tells you the basic information of the system, including “Model Name”, “System Description”, “Location”, “Contact”, “Device Name”, “System Up Time”, “Current Time”, “BIOS Version”, “Firmware Version”, “Hardware-Mechanical Version”, “Series Number”, “Host IP Address”, “Host Mac Address”, “Device Port”, “RAM Size” and “Flash Size”. With this information, you will know the software version used, MAC address, serial number, how many ports good and so on. This is helpful while malfunctioning.
On the top side, it shows the front panel of the switch. In the front panel, the linked ports will display green; as to the ports, which are link off, they will be dark. For the optional modules, the slot will show only a cover plate if no module exists and will show a module if a module is present. The image of module depends on the one you inserted. The same, if disconnected, the port will show just dark, if linked, green.
In this device, there are clicking functions on the panel provided for the information of the ports. These are very convenient functions for browsing the information of a single port. When clicking the port on the front panel, an information window for the port will be pop out as below. It shows the basic information of the clicked port. With this, you’ll see the information about the port status, traffic status and bandwidth rating for egress and ingress respectively.

3.3.2 IP Configuration
IP configuration is one of the most important configurations in the switch. Without the proper setting, network manager will not be able to manage or view the device. The switch supports both manual IP address setting and automatic IP address setting via DHCP server. When IP address is changed, you must reboot the switch to have the setting taken effect and use the new IP to browse for web management and CLI management.
Parameter description:
y DHCP Setting:
DHCP is the abbreviation of Dynamic Host Configuration Protocol. Here DHCP means a switch to turn ON or OFF the function. The switch supports DHCP client used to get an IP address automatically if you set this function “Enable”. When enabled, the switch will issue the request to the DHCP server resided in the network to get an IP address. If DHCP server is down or does not exist, the switch will issue the request and show IP address is under requesting, until the DHCP server is up. Before getting an IP address from DHCP server, the device will not continue booting procedures. If set this field “Disable”, you’ll have to input IP address manually.
10
y IP address:
Users can configure the IP settings and fill in new values if users set the DHCP function “Disable”. Then, click <Apply> button to update. When DHCP is disabled, Default: 192.168.1.1. If DHCP is enabled, this field is filled by DHCP server and will not allow user manually set it any more.
y Subnet mask: y Default gateway:
Set an IP address for a gateway to handle those packets that do not meet the routing rules predefined in the device. If a packet does not meet the criteria for other pre-defined path, it must be forwarded to a default router on a default path. This means any packet with undefined IP address in the routing table will be sent to this device unconditionally. Default: 192.168.1.254.
y DNS:
It is Domain Name Server used to serve the translation between IP address and name address. The switch supports DNS client function to re-route the mnemonic name address to DNS server to get its associated IP address for accessing Internet. User can specify a DNS IP address for the switch. With this, the switch can translate a mnemonic name address into an IP address. There are two ways to specify the IP address of DNS. One is fixed mode, which manually specifies its IP address, the other is dynamic mode, which is assigned by DHCP server while DHCP is enabled. DNS can help you easily remember the mnemonic address name with the meaningful words in it. Default is no assignment of DNS address. Default: 0.0.0.0
3.3.3 Time Configuration
The switch provides manual and automatic ways to set the system time via NTP. Manual setting is simple and you just input “Year”, “Month”, “Day”, “Hour”, “Minute” and “Second” within the valid value range indicated in each item. If you input an invalid value, for example, 61 in minute, the switch will clamp the figure to 59.
NTP is a well-known protocol used to synchronize the clock of the switch system time over a network. NTP, an internet draft standard formalized in RFC 1305, has been adopted on the system is version 3 protocol. The switch provides four built-in NTP server IP addresses resided in the Internet and an user-defined NTP server IP address. The time zone is Greenwich-centered which uses the expression form of GMT+/- xx hours.
11
Parameter description:
y Current Time: Show the current time of the system. y Manual:
This is the function to adjust the time manually. Filling the valid figures in the fields of Year , Month, Day, Hour, Minute and Second respectively and press <Apply> button, time is adjusted. The valid figures for the parameter Year, Month, Day, Hour, Minute and Second are >=2000, 1-12, 1-31, 0-23, 0-59 and 0-59 respectively. Input the wrong figure and press <Apply> button, the device will reject the time adjustment request. There is no time zone setting in Manual mode.
y NTP:
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will sync the time in a short af ter pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync via NTP because the switch will combine this time zone offset and updated NTP time to come out the local time, otherwise, you will not able to get the correct time. The switch supports configurable time zone from –12 to +13 steps 1 hour. Default Time zone: +8 Hrs.
y Daylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time lag or in advance in unit of hours, according to the starting date and the ending date. For example, if you set the day light saving to be 1 hour. When the time passes over the starting time, the system time will be increased one hour after one minute at the time since it passed over. And when the time passes over the ending time, the system time will be decreased one hour after one minute at the time since it passed over.
The switch supports valid configurable day light saving time is –5 ~ +5 step one hour. The zero for this parameter means it need not have to adjust current time, equivalent to in-act daylight saving. You don’t have to set the starting/ending date as well. If you set daylight saving to be non-zero, you have to set the starting/ending date as well; otherwise, the daylight saving function will not be activated. Default for Daylight Saving: 0.
The following parameters are configurable for the function Daylight Saving and described in detail.
Day Light Saving Start: This is used to set when to start performing the day light saving time.
Mth: Range is 1 ~ 12. Default: 1
Day: Range is 1 ~ 31. Default: 1
Hour: Range is 0 ~ 23. Default: 0
Day Light Saving End:
This is used to set when to stop performing the daylight saving time.
Mth:
12
Range is 1 ~ 12. Default: 1
Day:
Range is 1 ~ 31. Default: 1
Hour: Range is 0 ~ 23. Default: 0
3.3.4 Account Configuration
In this function, only administrator can create, modify or delete the username and password. Administrator can modify other guest identities’ password without confirming the password but it is necessary to modify the administrator-equivalent identity. Guest-equivalent identity can modify his password only. Please note that you must confirm administrator/guest identity in the field of Authorization in advance before configuring the username and password. Only one administrator is allowed to exist and unable to be deleted. In addition, up to 5 guest accounts can be created.
3.3.5 Management Policy
Through the management security configuration, the manager can control the mode via which user access this switch. According to the mode, users can be classified into two types: Those who are able to connect to the switch (Accept) and those who are unable to connect to the switch (Deny). Some restrictions also can be placed on the mode that the user connect to the switch, for example, we can decide that which VLAN VID is able to be accepted or denied by the switch, the IP range of the user could be accepted or denied by the switch, the port that the user is allowed or not allowed to connect with the switch, or the way of controlling and connecting to the switch via Http, Telnet or SNMP.
13
Parameter description:
y Name: A name is composed of any letter (A-Z, a-z) and digit (0-9) with maximal 8 characters. y VID:
The switch supports two kinds of options for managed valid VLAN VID, including “Any” and “Custom”. Default is “Any”. When you choose “Custom”, you can fill in VID number. The valid VID range is 1~4094.
y IP Range:
The switch supports two kinds of options for managed valid IP Range, including “Any” and “Custom”. Default is “Any”. In case that ”Custom” had been chosen, you can assign effective IP range. The valid range is 0.0.0.0~255.255.255.255.
y Incoming Port:
The switch supports two kinds of options for managed valid Port Range, including “Any” and “Custom”. Default is “Any”. You can select the ports that you would like them to be worked and restricted in the management security configuration if ”Custom” had been chosen.
y Access Type:
The switch supports two kinds of options for managed valid Access Type, including “Any” and “Custom”. Default is “Any”. “Http”, “Telnet” and “SNMP” are three ways for the access and managing the switch in case that” Custom” had been chosen.
y Action:
The switch supports two kinds of options for managed valid Action Type, including “Deny” and “Accept”. Default is “Deny”. When you choose “Deny” action, you will be restricted and refused to manage the switch due to the “Access Type” you choose. However, while you select “Accept” action, you will have the authority to manage the switch.
y Edit/Create:
A new entry of Management Security Configuration can be created after the parameters as mentioned above had been setup and then press <Edit/Create> button. Of course, the existed entry also can be modified by pressing this button.
y Delete: Remove the existed entry of Management Security Configuration from the management
security table.
3.3.6 Virtual Stack
Virtual Stack Management (VSM) is the group management function. Through the proper configuration of this function, switches in the same LAN will be grouped automatically. And among these switch, one switch will be a master machine, and the others in this group will become the slave devices.
VSM offers a simple centralized management function. It is not necessary to remember the address of all devices; manager is capable of managing the network with knowing the address of the Master machine. Instead of SNMP or Telnet UI, VSM is only available in Web UI. While one switch becomes the Master, two rows of buttons for group device will appear on the top of its Web UI. By pressing these buttons, user will be allowed to connect the Web UI of the devices of the group in the same window without the login of these
14
devices.
Parameter description:
y State: It is used for the activation or de-activation of VSM. Default is Enable. y Role: The role that the switch would like to play in virtual stack. Two types of roles, including master
and slave are offered for option. Default is Master.
y Group ID: It is the group identifier (GID) which signs for VSM. Valid letters are A-Z, a-z, 0-9, “ - “ and
“_” characters. The maximal length is 15 characters.
The most top-left button is only for Master device. The background color of the button you press will be changed to represent that the device is under your management.
Note: It will remove the grouping temporarily in case that you login the switch via the console.
The device of the group will be shown as station address (the last number of IP Address) + device name on the button (e.g. 1_SP1659P), otherwise it will show ” ---- “ if no corresponding device exists.
Once the devices join the group successfully , then they are merely able to be managed via Master device, and user will fail to manage them via telnet/console/web individually.
Up to 16 devices can be grouped for VSM, however, only one Master is allowed to exist in each group. For Master redundancy, user may configure more than two devices as Master device; however, the Master device with the smaller MAC value will be the Master one. All of these 16 devices can become Master device and back up with each other.

3.4 Port Configuration

3.4.1 Status
The function Port Status gathers the information of all ports’ current status and reports it by the order of port number, media, link status, port state, Auto-Negotiation status, speed/duplex, Rx Pause and Tx Pause. Extra media type information for the module ports 25 and 26 is also offered. It reports the latest updated status of all
15
ports in this switch. When any one of the ports in the switch changes its parameter displayed in the page, it will be automatically refreshed the port current status about every 5 seconds.
Parameter description:
y Port No:
Display the port number. The number is 1 – 26. Both port 25 and 26 are optional modules.
y Media:
Show the media type adopted in all ports. The Port 25 and Port 26 are optional modules, which support either fiber or UTP media with either Gigabit Ethernet (1000Mbps) or 10/100Mbps Fast Ethernet port. They may have different media types and speed. Especially, fiber port has comprehensive types of connector, distance, fiber mode and so on. The switch describes the module ports with the following page.
y Link:
Show that if the link on the port is active or not. If the link is connected to a working-well device, the Link will show the link “Up”; otherwise, it will show “Down”. This is determined by the hardware on both devices of the connection. No default value.
y State:
Show that the communication function of the port is “Enabled” or “Disabled”. When it is enabled, traffic can be transmitted and received via this port. When it is disabled, no traffic can be transferred through this port. Port State is configured by user. Default: Enabled.
y Auto Negotiation:
Show the exchange mode of Ethernet MAC. There are two modes supported in the switch. They are auto-negotiation mode “Enabled” and forced mode “Disabled”. When in “Enabled” mode, this function will automatically negotiate by hardware itself and exchange each other the capability of speed and duplex mode with other site which is linked, and comes out the best communication way. When in “Disabled” mode, both parties must have the same setting of speed and duplex, otherwise, both of them will not be linked. In this case, the link result is “Down”. Default: Enabled
y Speed / Duplex:
Display the speed and duplex of all port. There are three speeds 10Mbps, 100Mbps and 1000Mbps supported for TP media, and the duplex supported is half duplex and full duplex. If the media is 1Gbps fiber, it is 1000Mbps supported only. The status of speed/duplex mode is determined by 1) the negotiation of both local port and link partner in “Auto Speed” mode or 2) user setting in “Force” mode.
16
The local port has to be preset its capability. In port 1 – 24, they are supported Fast Ethernet with TP media only, so the result will show 100M/Full
or 100M/Half, 10M/Full and 10M/Half duplex. In port 25 and port 26, if the media is 1000Mbps with TP media, it will show the combinations of
10/100M and Full/Half duplex, 1000Mbps and Full duplex only. If the media is 1000Mbps with fiber media, it will show only 1000M/Full duplex.
Default: None, it depends on the result of the negotiation.
Rx Pause:
The way that the port adopts to process the PAUSE frame. If it shows “on”, the port will care the PAUSE frame; otherwise, the port will ignore the PAUSE frame.
Default: None
Tx Pause:
It decides that whether the port transmits the PAUSE frame or not. If it shows “on”, the port will send PAUSE frame; otherwise, the port will not send the PAUSE frame. Default: None

3.4.2 Configuration
Port Configuration is applied to change the setting of each port. In this configuration function, you can set/reset the following functions. All of them are described in detail below.
18
Parameter description:
y State:
Set the communication capability of the port is enabled or disabled. When enabled, traffic can be transmitted and received via this port. When disabled, the port is blocked and no traffic can be transferred through this port. Port State is configurable by the user. There are only two states “Enable” and “Disable” able to choose. If you set a port’s state “Disable”, then that port is prohibited to pass any traffic, even it looks Link up. Default: Enable.
y Speed / Duplex:
Set the speed and duplex of the port. In speed, 10/100Mbps baud rate is available for Fast Ethernet, Gigabit module in port 25, 26. If the media is 1Gbps fiber, it is always 1000Mbps and the duplex is full only. If the media is TP, the Speed/Duplex is comprised of the combination of speed mode, 10/100/1000Mbps, and duplex mode, full duplex and half duplex. The following table summarized the function the media supports.
Media type NWay Speed Duplex
100M TP ON/OFF
1000M TP ON/OFF
1000M Fiber ON/OFF 1000M Full
In Auto-negotiation mode, no default value. In Forced mode, default value depends on your setting.
y Flow Control:
There are two modes to choose in flow control, including Symmetric and Asymmetric. If flow control is set Symmetric, both parties can send PAUSE frame to the transmitting device(s) if the receiving port is too busy to handle. When it is set Asymmetric, this will let the receiving port care the PAUSE frame from transmitting device(s), but it doesn’t send PAUSE frame. This is one-way flow control.
Default: Symmetric.

Parameter description:
y Vmain: The volt is supplied by the PoE. y Imain: The sum of the current that every port supplies. y Pconsume: The sum of the power that every port supplies. y Power Limit: The maximal power that the switch can supply (Read Only). y Temperature: The temperature of the chip on PoE. y Port No: Port number. y Port On: Show whether the port is supplying the power to the PD or not. y AC Disconnect Port Off: Port is turned off due to the AC Disconnect function. y DC Disconnect Port Off: Port is turned off due to the DC Disconnect function. y Overload Port Off: The switch will stop supplying the power to the port due to the power required by
the PD that is linked to the port on the switch excesses the Class setting of the PD.
y Short Circuit Port Off: The switch will stop supplying the power to the port if it detects that the PD
linked to the port is short circuit.
y Over Temp. Protection: The port of the switch will be disabled due to fast transient rise in temperature
to 240oC or slow rise in temperature to 200oC.
y Power Management Port Off: Due to total power required by all PDs linked to the switch excesses the
power limit, so the switch stops supplying the power to this port after referring to the information of the priority.
3.5.2 PoE Configuration
In PoE Port Management function, user can configure the settings about PoE. The switch complies with IEEE
802.3af protocol and be capable of detecting automatically that whether the device linked to the port on the switch is PD (Powered Device) or not. The switch also manage the power supplement based on the Class of the PD, and it will stop supplying the power once the power required by the PD excesses the Class, Short Circuit or over temperature occurs.
22
Parameter description:
y Status: Include “Normal” or “Active” two kinds of status. The former means the port is ready to link and
supply the power to the PD at any time. The latter means the port is in the condition of supplying the power.
y State: ”Enable” means the manager allows the power supplied to the PD is legal while the port linked
to the PD; “Disable” means the port does not own PoE function.
y Priority: Three options are offered for the user to choose, including Normal, Low and High. Default is
Normal. The switch will stop supplying the power to the port based on the order of the priority Low Normal Æ High in case total power required by all PDs linked to the switch excesses the power limit. As the ports have the same priority, then the switch will cease the power supplement from the port with the highest port id (12
y Power(W): The power is consumed by the port. y Current(mA): The current is supplied to the PD by the port. y Class: The Class of the PD linked to the port of the switch.

3.6 SNMP

This function is used to configure SNMP settings, community name, trap host and public traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by identifying both community names, then it can access the MIB information of the target device. So, both parties must have the same community name. Once completing the setting, click <Apply> button, the setting takes effect.
Parameter description:
23
y SNMP:
The term SNMP here is used for the activation or de-activation of SNMP. Default is Enable.
y Get/Set/Trap Community:
Community name is used as password for authenticating if the requesting network management unit belongs to the same community group. If they both don’t have the same community name, they don’t belong to the same group. Hence, the requesting network management unit can not access the device with different community name via SNMP protocol; If they both have the same community name, they can talk each other.
Community name is user-definable with a maximum length of 15 characters and is case sensitive. There is not allowed to put any blank in the community name string. Any printable character is allowable.
The community name for each function works independently. Each function has its own community name. Say, the community name for GET only works for GET function and can’t be applied to other function such as SET and Trap.
y Default SNMP function : Enable
y Default community name for GET: public
y Default community name for SET: private
y Default community name for Trap: public
y Default Set function : Enable
y Default trap host IP address: 0.0.0.0
y Default port number :162
y Trap:
In the switch, there are four trap hosts supported. Each of them has its own community name and IP address; is user-definable. To set up a trap host means to create a trap manager by assigning an IP address to host the trap message. In other words, the trap host is a network management unit with SNMP manager receiving the trap message from the managed switch with SNMP agent issuing the trap message. 6 trap hosts can prevent the important trap message from losing.
For each public trap, the switch supports the trap event Cold Start, Warm Start, Link Down, Link Up and Authentication Failure Trap. They can be enabled or disabled individually. When enabled, the corresponded trap will actively send a trap message to the trap host when a trap happens. If all public traps are disabled, no public trap message will be sent. As to the Enterprise (no. 6) trap is classified as private trap, which are listed in the Trap Alarm Configuration function folder.
Default for all public traps: Enable.

3.7 DHCP Boot

The DHCP Boot function is used to spread the request broadcast packet into a bigger time frame to prevent the traffic congestion due to broadcast packets from many network devices which may seek its NMS, boot server, DHCP server and many connections predefined when the whole building or block lose the power and then reboot and recover. At this moment, a bunch of switch or other network device on the LAN will try its best to find the server to get the services or try to set up the predefined links, they will issue many broadcast packets in the network.
The switch supports a random delay time for DHCP and boot delay for each device. This suppresses the broadcast storm while all devices are at booting stage in the same time. The maximum user-defined delay
24
time is 30 sec. If DHCP Broadcasting Suppression function is enabled, the delay time is set randomly, ranging from 0 to 30 seconds, because the exactly delay time is computed by the switch itself. The default is “Disable”.

3.8 IGMP Snooping

The function, IGMP Snooping, is used to establish the multicast groups to forward the multicast packet to the member ports, and, in nature, avoids wasting the bandwidth while IP multicast packets are running over the network. This is because a switch that does not support IGMP or IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can only treat them all as the broadcast packet. Without IGMP Snooping, the multicast packet forwarding function is plain and nothing is different from broadcast packet.
A switch supported IGMP Snooping with the functions of query, report and leave, a type of packet exchanged between IP Multicast Router/Switch and IP Multicast Host, can update the information of the Multicast table when a member (port) joins or leaves an IP Multicast Destination Address. With this function, once a switch receives an IP multicast packet, it will forward the packet to the members who joined in a specified IP multicast group before.
Enabling IGMP with either passive or active mode, you can monitor the IGMP snooping information, which contains the multicast member list with the multicast groups, VID and member port.
Parameter description:
y IGMP snooping mode selection:
The switch supports three kinds of IGMP Snooping status, including “Passive”, “Active” and “Disable”.
Disable: Set “Disable” mode to disable IGMP Snooping function. Default: Disable
Active: In Active mode, IGMP snooping switch will periodically issue the Membership Query message to all hosts attached to it and gather the Membership report message to update the database of the Multicast table. By the way, this also reduces the unnecessary multicast traffic.
Passive: In Passive Snooping mode, the IGMP snooping will not periodically poll the hosts in the groups. The switch will send a Membership Query message to all hosts only when it has received a Membership
25
Query message from a router.
y IP Address:
Show all multicast groups IP addresses that are registered on this device.
y VLAN ID:
Show VLAN ID for each multicast group.
y Member Port:
Show member ports that join each multicast group. Member port may be only or more than one.

3.9 VLAN

The switch supports Tag-based VLAN (802.1q) and Port-based VLAN. Support 256 active VLANs and VLAN ID 1~4094. VLAN configuration is used to partition your LAN into small ones as your demand. Properly configuring it, you can gain not only improving security and increasing performance but greatly reducing VLAN management.
3.9.1 VLAN Mode
The VLAN Mode Selection function includes two modes: Port-based and Tag- based, you can choose one of them by pulling down list and pressing the <Downward> arrow key. Then, click Apply button, the settings will take effect immediately.
Parameter description:
y VLAN Mode:
Tag-based: (This is the default setting.)
Tag-based VLAN identifies its member by VID. This is quite different from port-based VLAN. If
there are any more rules in ingress filtering list or egress filtering list, the packet will be screened
with more filtering criteria to determine if it can be forwarded. The switch supports supplement of
802.1q.
Each tag-based VLAN you built up must be assigned VLAN name and VLAN ID. Valid VLAN ID is
1-4094. User can create total up to 256 Tag VLAN groups. Port-based:
Port-based VLAN is defined by port. Any packet coming in or outgoing from any one port of a
port-based VLAN will be accepted. No filtering criterion applies in port-based VLAN. The only
criterion is the physical port you connect to. For example, for a port-based VLAN named
PVLAN-1 contains port members Port 1&2&3&4. If you are on the port 1, you can communicate
with port 2&3&4. If you are on the port 5, then you cannot talk to them. Each port-based VLAN
you built up must be assigned a group name. This switch can support up to maximal 26
port-based VLAN groups.
26
y Symmetric Vlan:
This is called Ingress Rule (Rule 1, The Ingress Filtering Rule 1 is “forward only packets with VID matching this port’s configured VID”.). For example, if port 1 receives a tagged packet with VID=100 (VLAN name=VLAN100), and if Symmetric-Vlan function is enabled, the switch will check if port 1 is a member of VLAN100. If yes, the received packet is forwarded; otherwise, the received packet is dropped. Note: If Symmetric is enabled and port 1, for example, receives an untagged packet, the switch will apply the PVID of port 1 to tag this packet, the packet then will be forwarded. But if the PVID of port 1 is not 100, the packet will be dropped.
y SVL:
While SVL is enable, all VLANs use the same filtering database storing the membership information of the VLAN to learn or look up the membership information of the VLAN. While SVL is disabled, it means learning mode is IVL. In this mode, different VLAN uses different filtering database storing the membership information of the VLAN to learn or look up the information of a VLAN member.
y Double Tag:
Double-tag mode belongs to the tag-based mode, however, it would treat all frames as the untagged ones, which means that tag with PVID will be added into all packets. Then, these packets will be forwarded as Tag-based VLAN. So, the incoming packets with tag will become the double-tag ones.
3.9.2 Tag-based Group
It shows the information of existed Tag-based VLAN Groups. You can also easily create, edit and delete a Tag-based VLAN group by pressing Add, Edit and Delete function buttons. User can add a new VLAN group by inputting a new VLAN name and VLAN ID after pressing <Add> button.
Parameter description:
y Add Group:
Input the VLAN name, VID and then choose the member by ticking the check box beside the port No. to create a new Tag-based VLAN. As to the parameter of Untag, it stands for an egress rule of the port. If you tick the check box beside the port No., packets with this VID outgoing from this port will be untagged. Finally, press the Apply button to have the setting taken effect.
y Delete Group:
Just press the Delete button to remove the selected group entry from the Tag-based group table.
y Edit a group:
Just select a group entry and press the Edit button, then you can modify a group’s description, member and untag settings.
27
y VLAN Name:
The name defined by administrator is associated with a VLAN group. Valid letters are A-Z, a-z, 0-9, “ ­“ and “_” characters. The maximal length is 15 characters.
y VID:
VLAN identifier. Each tag-based VLAN group has a unique VID. It appears only in tag-based and Double-tag mode.
y Member:
This is used to enable or disable if a port is a member of the new added VLAN, “Enable” means it is a member of the VLAN. Just tick the check box beside the port x to enable it.
y Untag:
Select “untag” on the specified ports. Tag will be removed when packet is transmitted out of the ports.
3.9.3 PVID
In PVID Setting, user can input VID number to each port. The range of VID number is from 1 to 4094. User also can choose ingress filtering rule (Rule 2) to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule 2 is enabled, the port will discard all Untagged-frames.
Parameter description:
y PVID:
This PVID range will be 1-4094. Before you set a number x as PVID, you have to create a Tag-based VLAN with VID x. For example, if port x receives an untagged packet, the switch will apply the PVID (assume as VID y) of port x to tag this packet, the packet then will be forwarded as the tagged packet with VID y.
y Default Priority:
28
It bases on 802.1p QoS and affects untagged p acket s. When the packets enter the switch, it would get the priority precedence according to your Default Priority setting and map to 802.1p priority setting in QoS function. For example, while you set Default Priority of port 2 with 2 and transmit untagged packets to port 2, these packets will own priority 2 precedence due to your default 802.1p Priority Mapping setting in QoS function and be put into Queue 1.
y Drop Untag:
Drop untagged frame. You can configure a given port to accept all frames (Tagged and Untagged) or just receive tagged frame. If the former is the case, then the packets with tagged or untagged will be processed. If the later is the case, only the packets carrying VLAN tag will be processed, the rest packets will be discarded.
3.9.4 Port-based Group
It shows the information of the existed Port-based VLAN Groups. You can easily create, edit and delete a Port-based VLAN group by pressing Add, Edit and Delete function buttons. User can add a new VLAN group by inputting a new VLAN name.
Parameter description:
y Add Group:
Create a new Port-based VLAN. Input the VLAN name and choose the member by ticking the check box beside the port No., then, press the <Apply> button to have the setting taken effect.
y Delete Group:
Just press the <Delete> button to remove the selected group entry from the Port-based group table.
y Edit a group:
Just select a group entry and press the <Edit> button, then you can modify a group‘s description and member set.
y VLAN Name:
The name defined by administrator is associated with a VLAN group. Valid letters are A-Z, a-z, 0-9, “ ­“ and “_” characters. The maximal length is 15 characters.
y Member:
This is used to enable or disable if a port is a member of the new added VLAN, “Enable” means it is a member of the VLAN. Just tick the check box beside the port x to enable it.
