Hello, I have a managed switch and i have created three vlans in that switches. how can i communicate with these three vlans within this switch and also if i connect another switch with this one to the port belongs to vlan 1 then the frame comes out of third vlan to second switch will contain a vlan tag of 3 or 1. Please explain and also if i have a problem in stacking operations between switches what are the possible solutions and steps that can be tried. CAN ANYONE SUGGESTS ANY GOOD WEBSITES TO TROUBLESHOOT ENTERPRISE LEVEL PRODUCTS FREELY!!! PRODUCTS EXAMPLE:MANAGED SWITCHES, WIRELESS BRIDGES, ACCESS POINTS, HOTSPOT GATEWAYS, MODULES, ANTENNAS, CONNECTORS, STACKING OPERATIONS, ROUTING AND SWITCHING PROTOCOLS.

Thanks. We'll let you know when a new response is added.

First what brand of switch are you using. To be able to talk from on Vlan to another you have to be able to switch layer 3 traffic. Layer 3 being Network (IP) on the OSI model. If you are using a Cisco, HP, or other switch that support Layer 3 routing it will work just fine. Cisco website has example of most everything that you would like to setup.

    I agree with the previous post, each manufacturer is different. You do need layer 3 to get between the subnets. In other words, you have to route the traffic between the VLANs, as they are essentially different networks within your network. Stacking switches makes the first switch, or primary switch, the only switch that actually controls the configuration of the entire stack. It makes for less configuration. Configure one switch and the stack is configured.

    I have 3-com switches and it is not a layer 3 switch. It is a layer 2 switch and also i wanted to communicate between different vlan's within that switch.Can anyone please assist me in doing this operation. Do you people know any good websites for troubleshooting managed switches.

    Seeing that the switch does not support Layer3 switching you will need a router. You can use a Cisco router with one ethernet port if the IOS version support ISL trunking and if the 3com switch support ISL trunking. If the switch does not you will need a router that has the same number of interface as the number of vlans that you will route between. I would sudjest looking into getting a HP 5300 series switch. You can get the switch in any port config that you want. Also 3com switches don't have some of the managment fitures that new HP or Cisco switch have.

    I think u can communicate with different vlan if u can configure inter vlan switching with any layer three device without having no. of ports equal to no. of vlans. This can be helpfull for understanding better: http://www.dell.com/downloads/global/products/pwcnt/en/app_note_38.pdf

    Big question: does the switch support leaking VLANs? Look at Avaya Cajun switches for one.
