VLAN 3COM AND CISCO SWITCH

WAYNEP
I need to connect to subnets together via two switches. One is on a 3com 3870 and the other on Cisco Catalyst 2950xl. It appears the switches use different terminology. I have read thru lots of documentation regarding Vlan, Bridging, Vtp, etc? I think the more I read the more I get confused.

What I want to do is join two switches which are on two different subnets. I want switch A to access Switch B and visa versa.

How do I go about doing this? What settings do I need? Do I need ACL?

Switch a = 10.0.0.0 255.0.0.0 3com 3870
Switch b = 192.168.1.0 255.255.255.0 Cisco 2950xl

I would appreciate anyone?s input on this.

    I looked at your reply and queryed "router on a stick". I'm not using a router. Would the same apply to the 3com 3870 switch?

    Let me describe my situation in more detail:

    We have two Locations with are connect via a service installed by ISP.

    One side has subnet mask 192.168.1.0/24 gateway 192.168.1.16 the other 10.134.125.0/24 gateway 10.134.124.1

    What I want to do is plug a cable in to the existing switches and communicate back and forth.

    Q. Do I need to assign all ports to one vlan to enable them to communicate or do I just set the one port as the vlan?

    Q.,How do I set the port to recognize the subnet ip address?

    I?m confident I can setup the 3com side but I?m a beginner on the Cisco side.

    I would appreciate any additional feed back from anyone.

    The more detail the better.

    Thanks for your reply

    which will route traffic between vlans.

    trunking is between same vlans on different switches.

    you have to configure your 3COM switch as a layer 3 switch. your cisco is only layer 2-not support layer 3-.
    then make your uplinks Trunk ports.
