How to stop user privately setting up a static IP address?

Huawei S2300/3300/5300 series switch although no H3C switches am user-bind command, but through the DHCP Snooping function can also be realized IP+MAC+ port binding to prevent users set up a static IP address. For example, if the request port Ethernet0/0/1 in addition to the static IP address for the, MAC address for the 001c-2309-9aa7 corresponding to the user, all other static IP users can not access the internet. Configuration is as follows:
Configure the device DHCP Snooping
# enable the global DHCP Snooping function.
[Quidway] DHCP snooping enable
# configure user side interface of VLAN.
[Quidway] VLAN 100
[Quidway-vlan100] quit
[Quidway] interface Ethernet 0/0/1
[Quidway-Ethernet0/0/1] port default VLAN 100
[Quidway-Ethernet0/0/1] quit
# enable VLAN DHCP Snooping function.
[Quidway] VLAN 100
[Quidway-vlan100] DHCP snooping enable
# configuration interface for packet inspection at the user side
[Quidway] interface Ethernet 0/0/1
[Quidway-Ethernet0/0/1] DHCP snooping check ARP enable
[Quidway-Ethernet0/0/1] DHCP snooping check IP enable
[Quidway-Ethernet0/0/1] quit
# configuration static binding table entry

Configuring the switch S5700-28P-LI-AC, I had no idea: how to Check Whether the IP Address in the NeighborInformation Is Correct?

Run the lldp management-address command to configure the switch management address of the local device. Then view the management address of the local device on the neighbor device to check whether the displayed IP address is the same as the configured one.

The more information about technical support you can consult with our technician - Bill, and his e-mail address is as below:

Sir I have 4200 series 26 ports Switch i want to Configure intra VLAN But I am Getting a problem to Configure that switch . After Cnfigure VLAN on Consol prompt. I am not accessing to my Server & WAN...

If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

I am trying to configure a netgear switch (48 ports)but everytime I configure the static IP address for the switch, it keeps defaulting to a different IP address once it is powered down. I have also tried...

I'm not too familiar with Netgear switches, but if you told me you were having this issue with a Cisco switch, I'd tell you that after you change the IP address you need to save your configuration to NVRAM using the "copy run start" command. A Cisco switch will look to start using the configuration stored in NVRAM when it is booted. Changes are made to the configuration in RAM and are lost when reboot occurs unless they are first saved to NVRAM. Perhaps there is a similar command for the Netgear switch. Hope this helps

Here's what you need to do:

First, be sure to assign an ip address(in the proper subnet) to each VLAN.

Second, use the ip helper-address command in the context of each VLAN, the address used should be the address of the DHCP server

Third, Add a scope for each additional VLAN on the DHCP server.

The switch will route the DHCP request to the proper server based on the ip helper-address command parameter and based on the ip address of the VLAN that is passed tot he server, a DHCP address in the proper subnet is automatically configured.

Here is a sample:

ProCurve Switch 3500yl-24G-PWR# configure
ProCurve Switch 3500yl-24G-PWR(config)# vlan 33
ProCurve Switch 3500yl-24G-PWR (vlan-33)#ip address
ProCurve Switch 3500yl-24G-PWR (vlan-33)# ip helper-address

How to assign IP address to HP procurve1800 switch?

The 1800 series do not have CLI so you should connect directly to any RJ-45 port.

I quote from the installation guide:
"In the factory default configuration, the default IP (Internet Protocol) address of the switch is and the subnet mask is"

So set your PC IP address in the same subnet and access it through your web browser. If it has not the default configuration, interconnect the switch ports 1 and 2 and reboot it.

Hope this helps,

take care

How to Configure the Switch
Some configuration is necessary to enable the switch’s advanced switching
capabilities. This is achieved via the Command Line Interface (CLI). On the
AT-8624T/2M, you can also use the Graphical User Interface (GUI).
Using the CLI to configure a switch
1. Connect a terminal or PC to the Terminal Port (ASYN0).
Using the supplied RS-232 DB9 serial straight-through cable, connect your
terminal or PC to the RS-232 Terminal Port:
• For the AT-8624T/2M and AT-8624PoE, the RS-232 Terminal Port is on
the front panel.
• For the AT-8648T/2SP, the RS-232 Terminal Port is on the back panel.
2. Set the communication parameters.
Set the communication parameters on your terminal or terminal emulation
program to:
• Bit rate: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
3. Log in.
After the switch has booted, the login prompt appears. If the login prompt
does not appear, press [Enter] two or three times.
When the switch boots for the first time it automatically creates an
account with manager privileges. The account has the login name manager
and the password is friend.
At the login prompt, enter the login name and password:
Login: manager
Password: friend
The switch’s command prompt appears. Now use the CLI to configure the
Using the GUI to configure the AT-8624T/2M switch
This section describes how to establish a connection to the AT-8624T/2M switch
through the GUI so you can configure it before installing it in your LAN.
1. Select a PC to use and identify its subnet.
You can browse to the switch from any PC that is running a supported
operating system with a supported browser installed. JavaScript must be
enabled. If you are using a toolbar or plug-in on your browser to block popups,
disable it while using the GUI. The GUI displays detailed configuration
options and information in pop-up windows.
2. Connect the PC to the switch.
Use an Ethernet cable to connect an Ethernet card on the PC to any one of
the switch ports.
You can browse to the router through any VLAN, as long as you give that
VLAN an IP address. These instructions assume you are using vlan1. All
switch ports belong to vlan1 by default.
3. Access the switch’s command line interface.
Access the CLI from the PC, as described in the previous section, “Using
the CLI to configure a switch”.
Installation & Safety Guide 13
4. Enable IP.
enable ip
5. Assign the vlan1 interface an IP address in the same subnet as the
add ip interface=vlan1 ip=ipaddress mask=mask
6. Save the configuration and set the switch to use it on bootup.
create config=your-name.cfg
set config=your-name.cfg
7. On the PC’s web browser, bypass the HTTP proxy server, if
8. Point your web browser at IP address for vlan1.
9. At the login prompt, enter the user name and password.
User Name: manager <the default>
Password: friend
The System Status page is displayed. Select options from the sidebar menu
to configure and manage the switch.

sidebar menu or on any pop-up page

I hope this helps you out

Duplicate/incorrect MAC addresses in the CAM table

This is from the Cajun P333R manual but it should be very similar if not identical.

Good Luck.

arp timeout Command
Use the arp timeout command to configure the amount of time that an entry
remains in the ARP cache. To restore the default value, 14400, use the no form of
this command.
The syntax for this command is: arp timeout <seconds>
The syntax for the no form of this command is: no arp timeout <seconds>
To set the arp timeout to one hour:
Router(configure)# arp timeout 3600
To restore the default arp timeout:
Router(configure)# no arp timeout
ip-address IP address, in dotted decimal format, of the station
hardware-address 48-bit address of the local data link
seconds The amount of time, in seconds, that an entry
remains in the arp cache.
