Hi,

I am not a networking guy but am forced into this role due to lack of help. Here is the scenario.
I have a cisco 3550 and 2750 which will have one server a piece and .multiple clients hanging off of it. I need to join these switches to an exisiting network. This is what I have done so far.

The current network does not have a vtp domain set up so I have created a vlan that exists on their root switch. I was told that their vlan had to be on our switch.
I ran switchport mode access:
switchport access vlan #.
So now I see the vlan but still cannot hit their switch. I need to know is there anything else I need to do or did I miss a step. Thanks for your help.

1) Connect the two switches using an Ethernet crossover cable
     A trunk should automatically be created.
2) Create the VLAN
     vlan # ! replace # with VLAN number
3) Add the necessary ports to the new VLAN
     interface fastethernet 0/p ! replace "p" with interface number
     switchport access vlan #
4) Exit configuration mode and save config.

Do a show interface XXX switchport on both ports and paste it here.  Also could you elaborate on the symptoms are you not able to telnet to the other switch?  Pass traffic through the other switch?  Etc.

Guys I really appreciate it. The biggest problem is that the switch that I connecting to is not ours. Now does anything have to be done on their side or is it just our side that I need to config the vlan on?

Once again thanks!

Possibily.

If the switchport on the other switch has had it's configuration changed from the defaults, then it may need to be configured. Without knowing the current config of the other switch, it's impossible to say.

Yes their side is configured.  Since it is configured and the vlan that I added with the ports are their vlan. Is there anything you can think of that would be preventing anything? Is there a security setting or anything? They are not running port security and so is there like a certain access mode that needs to changed or anything? Thanks...I think I am almost there.

Are they trunking the link to you?

Can you post the current config of your switch and indicate which port goes to the other switch and which ports your hosts are connected to.
