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

100% CPU utilization all the time


Your switch could be looped. You could either unplug each rj45, or go into each port and use the shut command to find out if that is the case. If there are other switches hung off of this one, you could use the spanning tree command to auto shut the redundant interface down.

My Netgear FS605 stopped working. All lights flashing about 1x/sec. No change in cabling or configuration in past year. Upstream Linksys N wireless router working fine. Tried disconnectring ethernet...


Are you able to ping between systems connected to the same Netgear FS605 switch and in same VLAN.
I suspect either switch port or Uplink cable issue.
Please try changing a new cable and if no improvement then please try with a different switch port.

How to connect the network cable


you will have 8 ethernet ports in this switch... One port is for input all the other ports are for output...
If you dont have any dedicated uplink port, then any port can be used as an uplink port and other ports becomes downlink port...
The Lan slot of router should be connected to the uplink port in switch.... you can connect upto 7 computers in this switch(in downlink ports)...

What command used to convert a switch port into a routed port in 1648T switch..


Hello
You can turn any router into a switch by disabling the DHCP server on the router. Now as far as being able to get an IP for a machine, there must be a gateway device on the network whether that is a computer, router or FW appliance that DHCP IP(s) or static IP(s) can be used by the switch. You want to the machines on the router (now a switch) not accessible, then you change the subnet on the router (now a switch) to be a different subnet mask than the gateway device.


The principles for making a router a switch and using it are the same no matter if it's a wire or wireless router or brand name being used.

If you want to use two routers with each using their own DHCP and subnets, then you connect routers together taking the WAN port of the second router and plug it into the Uplink port of the gateway router or FW appliance if the device has an Uplink port.


Hope it will help, if so do rate the solution

I am connecting 4 nodes through 2 switch located at 400ft distance. the data transfer is not working. 2 nodes are connected to each switch, both nodes connected to individual switch communicates with each...


Just to clarify, you have 4 computers connected to two ethernet switches. Two computers are connecteh to each ethernet switch and a network cable connecting the two ethernet switches 400ft apart.

For all the computers to communicate with each other, they all need to be in the same workgroup "name".
The cable joining the two ethernet switches need to be connected to the RJ45 UPLINK port on both the ethernet switches, and the uplink port may have a switch (the switch allows it to function as a standard RJ45 port or a RJ45 uplink port).
If there is no RJ45 uplink ports on the ethernet switches then a cross over network cable is needed to connect the ethernet switches together.

I have 3 computers connected by D-Link router. Recently I found that the router was not working so I bought a netgear GS608 router to replace it, but I can't find the cd or instruction leaflet so I have no...


The thing is that this is not a router as I know. It has to be a switch. As I know.
You still need a router to connect to the internet and do the routing. First check that.
To configure the network, you have to connect 3 PCs to your switch. Connect the switch to a router. Use router's uplink or auto sense ports. Connect both the ports with a straight through cable. If you don't have such port in the new router (when you buy, check it first), use a standard ethernet port. But you have to use a cross-over cable. Then go to router's login page and log in. Set the dhcp. It will assign adresses to your switch and PCs also. Make sure you don't have static configurations in you machines which may confuse by duplication. To use dhcp, set you machines' IP settings to obtain IP and DNS automatically. Set the default gateway IP as the router's IP. Then open a command prompt and ping the router. Then ping the switch(first do that). Then ping other PCs. After verifying the connectivity, plug the cable(internet) and your router has to have such a port. Go to WAN settings and do any other configuration. Cable internet (if its adsl instead of TV cables), you will required to provide authentication information with other settings. For cable internet instead of ADSL, the configurations might be different and I don't have experties on that (cable TV used as a medium to access the internet). So hopefully this will do your task.
If this solution is able to solve ur problem, please rate it. Thanks and Good Luck. :)
