Having 1 Vlan On Two Different Floors

Choose any random number for the vlan.

Having 1 vlan on two different floors.

The 802 1q draft standard defines layer 1 and layer 2 vlan s only. I want dhcp server to distribute different ip addresses for different vlan. The default ethernet vlan is vlan 1. We ll call them vlan a on 192 198 0 1 and vlan b on 192 168 16 1.

We have to maintain the network isolation for pci credit card compliance but i have a server on vlan a 192 168 0 45 that computers on both vlans need to access. Hello i have a problem with the following topology i have 2 vlan two different floors of the building. My concern is that the vlan per floor argument for user vlans 24 doesn t scale as larger offices will require more vlans per floor. Floor 1 vlan 130 192 168 130 0 24 floor 2 vlan 110 192 168 110 0 24 something i can not configure dhcp server to dis.

The present standard is for a mgmt lan and 2 user vlans 1 voice 1 data. The first floor is supported by switch 1 and the second floor is supported by switch 2. You may have one network in vlan 2 and another in vlan 1001 it really doesn t matter since that vlan id is there to identify it from any other vlan. Navigate to lan vlan settings.

Because of office real estate people are sitting wherever an open desk can be found. This keeps the other vlans more secure. Be sure that this vlan does not have dhcp inter vlan routing or device management enabled. Back to table of contents.

A large drawback to this solution is that hosts in the same vlan but in different subnets would require a router to communicate. Vlan ids are 1 4096 that means you may have 4096 vlans in a network and as per my previous example you can use any vlan you like in that range. It is still better to have a 1 1 relationship between vlans and ip subnets. As a result these vlan s will remain proprietary.

Put any unused lan port on this vlan. Vlan design guidelines 3 3 2 1 cisco switches have a factory configuration in which default vlans are preconfigured to support various media and protocol types. While this might serve well as a migration tool it isn t the cleanest way to configure a network. It is safe to say that the marketing and engineering departments have different.

Best practice 3 create a dead end vlan for unused ports. It is a security best practice to configure all the ports on all switches to be associated with vlans other than vlan 1. I have two vlans each with a different subnet. 4 2 types of connections.

Hi jon thanks for your input.
