CISCO Catalyst 2950 Series Setup
Hi,
I've been having some trouble initially setting up a Cisco Catalyst 2950 Series switch.
I connect the concole cable and am able to view the Cisco IOS through Hyperterminal in Windows.
I then use the "setup" command to initially set up the switch. After entering all the details, I connect a patch cable into port 1x (or whatever) of the switch so that I can customise the setup using the web interface through my network. This is what I normally do.
The problem is that after I connect a patch cable to our network, the network active light does not show in the port, and I am unable to ping the switch with the IP that I allocated it.
Any help will be appreciated!

Did you make sure to turn on the ports..sorry for the silly question but had to ask?

dis1931,
I have never had to turn the ports on switches I've installed before.
If this is necessary, how do I go about it?
Thank you.

Is it a new switch? or might ports have been turn off....? Anyways it has been a while since my switch config days but i believe after entering ena mode then you would goto "conf t", then "no shut fa0/1-24"....sorry if my syntax is off like it said it has been a while but it should be something similar to that...you can check to see if they are on or off by checking your running config...just typw "show conf" or "show run". It should say whether the ports are on or off.

It is a new switch.
I've tried to perform the commands that you mentioned, but some don't coincide.
When typing "show conf" the configuration settings are shown, but their state (ip/down) is not displayed.
I've also tried "conf t" then "no shut fa0/1-24" as you suggested, but it doesn't recognise "fa****".
This is a pretty stubborn switch. Normally the setup isn't this difficult. The manual I downloaded from the Cisco site for this switch isn't much help either.
Any more suggestions?

There's only a couple of things that cause the port to not detect link. Check the following...
1) make sure your cable is good, straight through cable should be used for host to switch, but switch/hub to switch/hub should be a cross over cable.
2) make sure that your NIC and the switch port have the same setting for speed. You should both be set to auto or you should both be set to 10 or 100. Either way, if this doesn't match, then you are not going to have link on one side.
No light means that you have no link. If your port was admin shut/disabled your port would show an amber light.

johntsai90,
Even after trying the commands you suggested, I "reload" then type "show ip int brief", and Vlan1 Prot state is till down as follows:
switch#show ip int brief
Interface IP-Address OK? Method Status Prot
ocol
Vlan1 61.8.9.224 YES NVRAM up down
FastEthernet0/1 unassigned YES unset down down
FastEthernet0/2 unassigned YES unset down down
I tried this several times - still with no luck!

I need your network schematic,
Is that the router goes to switch uplink port and workstation plug into one of the port from switch?
If it is, make sure the duplex and speed are the same between each side, and the cable got to be straight-through.
If your workstation has pluged into port 1.
please post the result of "show fa0/1", "show run", and "show controller ethernet fa0/1". That should give you some ideas of physical level.

johntsai90,
I have resolved the problem!
The device that this switch is connected to was not in full duplex mode. Once I changed this, the link worked perfectly.
In now get the following:
switch#show ip int brief
Interface IP-Address OK? Method Status Prot
ocol
Vlan1 61.8.9.224 YES NVRAM up up
FastEthernet0/1 unassigned YES unset down down
FastEthernet0/2 unassigned YES unset down down
Thank you for all your help!
