Why Addresses in the IP Address Pool on a Switch Are Exhausted When the Switch Functions as a DHCP Server and It Has a Few Clients?


If the IP address pool has much more resources than needs of clients, the following two reasons may cause address exhaustion:
1. An attacker keeps changing the CHADDR field and sending DHCP Discover packets to exhaust addresses. If so, contact Huawei engineers to deploy DHCP snooping to protect the IP address pool.
2. The DHCP server ping function is enabled on the DHCP server. This function tries to ping the allocated addresses before responding to DHCP Offer packets. If a client responds to any ping packet, the DHCP server considers that there are address conflicts and addresses are exhausted. To solve this problem, two methods are available:
1. Capture packets on the ports connected to the DHCP server. If a client responds to ping packets, prohibit the client.
2. Disable the DHCP server ping function using the undo dhcp server ping packet command.
3. Such as S5700, S6700

Why am I losing internet speed when using router goes fro 60mps to 5-10 mps


how did you bypass the router ? what is connecting to the internet if you bypass the router ? question is the device connecting to the internet got a DHCP server and does the router have a DHCP server. What IP ranges are the two DHCP servers allocating.
You may need to switch off one of the DHCP servers in one of the two devices. Probably the DHCP servers are confusing each other .
Only my educated guess with the limited information on how your network devices interact. .

Log in on your router manager http://192.168.x.x and enable DHCP.DHCP provides an automated way to distribute and update IP addresses and other configuration information on a network. A DHCP server provides this information to a DHCP client through the exchange of a series of messages, known as the DHCP conversation or the DHCP transaction. If the DHCP server and DHCP clients are located on different sub-nets, a DHCP relay agent is used to facilitate the conversation.

  1. Connect to your router (by typing 192.168.0.1 or 192.168.1.1 into the URL bar) and log in. Check your user manual or documentation if you do not know the log-in credientials.
  2. 180px-dhcp_router_setup.jpg magnify-clip.png Router Setup tab Make sure you are in the Setup -> Basic Setup category.
  3. 180px-dhcp_router_disabled.jpg magnify-clip.png DHCP is Disabled Scroll down until you see 'DHCP Server' - if it is disabled, select 'Enable'
  4. 180px-dhcp_router_enabled.jpg magnify-clip.png Enable DHCP If you want, you can change the number that the DHCP IP assigning starts. This is optional, and is totally dependant on personal preference.In this picture, the maximum number of DHCP clients is 3. You may need to increase this number according to how many people will need a dynamic IP address on your network. Once the max is reached, no one else can get an address until one expires!
  5. Use the DNS servers provided to you by your ISP, or use the following DNS servers: 205.152.37.254, 205.152.132.235, 205.152.132.23; There are many DNS servers out there. It's best to use your ISP's if possible.
  6. dhcp_router_save.jpg magnify-clip.png Don't forget to save! Scroll down and click 'Save Settings'

We have a DHCP problem with our thin client HP T5540, the network interface can't get an ip address fom the DHCP server for 30 seconds so it can't connect to citrix xen serverver for virtualization...


First of all check the configuration of the unit if it's AUTOMATIC IP/DHCP, if all OK you can test by configuring a static IP (use an unused IP in the server's DHCP table) than check the connectivity (ping something), if that works you have a server rule/DHCP or DNS problem

if it's still not working check the cabeling and connectors for connectivity (with a good cable tester) or an other (working) computer.

Good luck!

Wi-Fi not connecting on Toshiba Satellite A15-S157 PC Notebook


you tried giving it a static IP address rather than using automatic settings (i.e. DHCP). Sure enough, this cured the problem, connected fine. I looked in the dhcp server logs and while it was not complaining that the IP address pool was all used, it did seem that all the IP addresses available were being used. I increased the number of IP addresses available to be allocated by the dhcp server and problem solved. The big mystery to me is why Windows XP would report this as a problem with a weak signal? Isn't the access to the dhcp server and the allocation of the IP address at a layer above the wireless connection? Anyway, it's useful to be warned that the wireless diagnostics are misleading.

HP Officejet printer


i assume that your printer is connected to a network. if so, it could be that the printer is set to use dhcp for the ip address. and if that's the case, it's better to set the printer to use static ip address since there would come a time that the dhcp server (a router most of the time) would provide another ip addresses to all the devices connected to it. that could be the reason why you are getting a "no connection" message (disconnecting and reconnecting it at times would solve the problem temporarily).

here are the steps on how to set static ip on the printer using a windows computer.(Note: the installation cd can automatically assign a static IP address as long as the printer does not obtain a dynamic (dhcp) address)

- boot up your computer the normal way so it'll get an ip address from your dhcp server
- then turn off your dhcp server so that the printer will not get any ip address via dhcp
- reset the printer to set its factory default configuration (with no dhcp address)
* unplug the printer from the power
* plug the power cord back in while holding in the printer’s
report button (it will try to find a dhcp server; after about three
minutes of no dhcp response, the printer will default to a static ip address of 192.0.0.192

- then print a configuration page to confirm that the ip address of the printer is set to 192.0.0.192

- then press the report button (wait until IP address is 192.0.0.192 before proceeding. if it remains set to 0.0.0.0, check the network cable connection to the printer and to the network is secure. If some other address appears repeat steps 3 and 4 until the default address appears
- you can now start the software installation cd

*during the installtion, follow these steps:
- select the model of the printer that you are using which is hp officejet before clicking on "next"
- then select "do network settings for me, then press "next
*follow the instructions on the remaining install screens
- the software will pick an ip address in the private 169.254.x.x range (not available on the open Internet) and permanently assign it to the printer. it will also set up a static route to that address in the computer’s printer configuration
- turn the dhcp server back on by turning on the dhcp server by
connecting your cable/dsl modem or dhcp to the network. because the hp now has a permanent static ip address, it will
no longer try to use dhcp server to get an address
- install the software on the other computers on the network who will be using the printer. the installation software will discover the hp printer at the 169.254.x.x address, and will add the static IP address in each computer’s printer configuration

Note: if the installation cd will permit you to change th private ip address from 169.24.x.x, it's better to set it on the same range as of the ip address given by your dhcp server (for example your dhcp server provides ip addresses starting from 192.168.1.100-192.168.1.250, set the printer's ip address to 192.168.1.59-below or any ip address that will not compromise any ip addresses that were already being used by your other devices)

hope this'll help you but if you'll have other concerns just ask me.

ciao!

Xbox 360


Either the network connection between the 360 and router is not working correctly, or your router is not configured properly for DHCP.

DHCP (Dynamic Host Configuration Protocol) is a protocol that automatically assigns a network address (and some other settings) to your computer....or Xbox in this case. It works like this....when your Xbox connects to the network, it sends out a broadcast packet on the network that looks for a DHCP server. If a DHCP server is present, it responds. Next the Xbox requests its network address and other settings from the DHCP server. Your WGR614 router has a DHCP server function built in, but it may not be enabled. Try reconfiguring the router using the Netgear "Smart Wizard" installation CD and be sure to enable the DHCP capability, if asked.

ISA 2004 - DHCP + MAC Address


This would need to be configured on whatever system it is that is serving DHCP. Assuming it is the same box as ISA Server, it would then have to be running Microsoft DHCP. In Microsoft's DHCP, you can assign reservations for specific MAC addresses. You need to open the DHCP management console, then expand out the server name. If the server name is not listed, you will need to connect to the server hosting the DHCP service by right clicking on the root node, etc.

Assuming you have a connection to the DHCP server and can see the zone you are referring to (172.16.2.0/23 which contains all addresses in the subnet to which you refer), under the zone, right click on Reservations and choose New Reservation. Enter a name, the specific IP address for that machine and the MAC address. That's all there is to it. Next time that machine requests an address from the DHCP server, it will issue the address you configured. It will not issue it to any other machine.
