Installing Cisco 2960 24 port POE switch


i have to install 3 2960 switches into our new office. I have setup the switches with an IP address each and that is it. I have connected two PCs to one of the switches and set them with static IPs address in the same subnet as the switch itself. When I go to ping each pc or the switch I get no reply. \can you please suggest a basic config that will allow comms across this switch.

secondly as I have 3 of these switches I need to connect them together. What ports do I connect them too and do I need to add anything to the configs?

Lastly i have a cisco 2911 router which i would like to connect to network. is it ok if i just connect this to come of the FE ports? also for ports 1-10 I would like any device connected to these ports to be given dhcp IP addressing range How is this done and is it best to use the 2960 or the 2911 to do this?all other ports have no dhcp.

|I know there is a lot above so any help would be great please.

Thank you

Out of the box, all ports on the 2960 should communicate with each other. Anything plugged into one port with an IP address in the same subnet as anything else should be able to communicate.
If you assign an IP address to vlan1 you should be able to ping that IP from any PC connected to the switch if it has an address in the same subnet.

To connect the switches together, simply plug in a patch cable between them. No specific ports required. They should default to automatically trunk with each other.

You can plug the router into any port with no problem. No special config for either one.

You cannot specify a port range that will get specific IP addresses via DHCP. DHCP is a broadcast which is sent to all ports at once. The 2911 can be your dhcp server.

We need to keep the discussions limited to the first part of the question. Our solution database is most effective if we have one issue, one solution. You can ask multiple questions to cover the other multiple issues if you need more information or details on your secondary questions here.

1) Irmoore is correct, out of the box all ports should be able to communicate with each other, however depending on how you assigned the IP to the switch this may be why you are having the problem.  Please post the configurations of the switches.

2) Most Cisco switches come with uplink ports (usually faster) these will be 25 and 26 on your switch and may either be Ethernet, fiber, modular (so you can insert either Ethernet of fiber port), or Ethernet and modular (modular here would be for fiber connections and may be numbered 27 28)

3) I am assuming you are planning on connecting servers and other network components here so I would recommend setting these up with static IPs or using DHCP reservation based on the MAC address of the equipment.  Other than that there is no way to force the switch to assign those IPs to those ports unless they are in a separate VLAN and a separate IP space from the rest of the network.

Thank you both.

I have connected all switched using ports 24 on all three and it works perfectly. I might switch to uplink on monday. With regard to pinging the switches I needed to enter cmd 'no shutdown' to bring up vlan1.

Cheers for the help!!
