Problem with connecting two 24 port 3 com switches

interfaces (slot/port) admin down
eg
interfaces 3/24 admin down

The above example will disable port 24 on slot 3. Admin up to enable it again.

A router is a more sophisticated network device than either a switch or a hub. Like hubs and switches, network routers are typically small, box-like pieces of equipment that multiple computers can connect to. Each features a number of "ports" the front or back that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. While routers, hubs and switches all share similiar physical appearance, routers differ substantially in their inner workings.


Splitter is nothing but a Switch.
Switches may operate at one or more OSI layers, including physical, data link, network, or transport (i.e., end-to-end). A device that operates simultaneously at more than one of these layers is known as a multilayer switch.
In switches intended for commercial use, built-in or modular interfaces make it possible to connect different types of networks, including Ethernet, Fibre Channel, ATM, ITU-T G.hn and 802.11. This connectivity can be at any of the layers mentioned. While Layer 2 functionality is adequate for bandwidth-shifting within one technology, interconnecting technologies such as Ethernet and token ring are easier at Layer 3.
Interconnection of different Layer 3 networks is done by routers. If there are any features that characterize "Layer-3 switches" as opposed to general-purpose routers, it tends to be that they are optimized, in larger switches, for high-density Ethernet connectivity.

Hi,
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

interConnecting two switches will need a crossover cable. Please use a crossover cable.

connect only DGS -1024D to your network....it will be faster...
because DGS supports 10/100/1000 speed.... but DES supports only 10/100 speed...
connect DGS directly to your network and work with that... if you wish to extend the number of ports then connect the DES to one of the ports of DGS

and dont connect DGS to one of the ports of DES

1.) The setup needs changing
2.) first off the dss-24 is a network switch not a router
3.) all of your pc equipment should be pluged into that device.
4.) chose one port as an uplink to your att modem
I think your problem is that the new modem is only giving out one ip address. So what ever first pc is turned on that is the one that grabs the address.
5.) you will most likly need a router to take the one ip address assigned via att then dole out additional ones. Remember the dss-24 is not a router. It simply connects everyone together. Each device still needs an ip address given from somewhere. Your old cable modem probibly did that but your new att dsl most likly does not.hence the new router will do that.....
to set it up do the following
2.) Find out the ip setup needed for your dsl service
A.) gateway ip
B.) primary & secondary dns server ip`s
C.) subnet mask
3.) get into the setup of your new router and then plugg in
all of these values using a fixed if address in the router
4.) connect routers wan port to one of the modems port. u may have to use a cross cable or straight look at the link lites to find out if they are talking to each other
5.) make sure that the routers lan side is setup for DHCP
6.) connect one lan port off the router to an uplink
of the dss-24. Then reboot everything
7.) viola it should all work internet on evey machine and file sharring.

You have to interconnect the switches with the cable. Connect the computers to the switches. Also connect the internet cable in the switch too.

Hi,
try to create 2 comp lan, take both pc in same subnet and connect those to switch.

thats not a big diffrence if you use a 24 port switch or if you use 48 port switch actually switch is used to a number of connection not for a internet speed that is use for a networking if you want to upgrade your configuration then you upgrade your ram and our hard dives configuration

It does not have to be port 24 to port 24 - You just need to make sure that whatever port you use is configured the same way as port 24 - Example: Log into switch #2 and set port 23 with the same attributes as port 24. Also log into you new switch and make sure port 23 (or 24) is configured the same as those on switch #2. You can the cleanly go from switch #1 - port 24 to switch #2 - port 23 AND switch #2 port 24 to switch #3 port 23 - If you also configure switch #3 port 24 like the others you'll be ready for any additional expansion
