VLANS
I have a network with 250 pc's using a 10.10.1.x with 255.255.255.254 mask. 1) How do I subnet? (I need a specific example) 2) Do I need another router for subnetting? 3) We have Cisco 2950 switches on the LAN. I know VLANS can be created on the switches. How do I do the VLANS? 4). At time the switches just hang requiring a reboot. What could be the cause?

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

Hi in your scenario

Since you have 250 PCs means you are using 10 2950 switches.
You can create a VLAN for each closet starting from subnet
10.10.1.0 /24
10.10.2.0/24 and so on upto 10.10.10.0/24.
Connect all these switches to either 3750 – 12 G or 4500 Series Switch (collapsed core deisgn) with fiber uplink ports as a distibution switch, where you can configure your VLANs, enable intervaln routing , QOS service etc).

Make sure you have one switch as sever farm switch whihc is connected to your distibution siwtch.

Make sure there are no network loops in your network , which may force to hand your switches. If you provide your complete scenario with network layout a better solution can be provided.

Cheers
Yasir

    Firstly, your statement "I have a network with 250 pc's using a 10.10.1.x with 255.255.255.254 mask" seems off... did you mean to say your subnet mash is a /24? As Yasir mentioned, a basic network topology would be great and help us understand how you're connected and where we can go from there. But, to answer the spirit of your question: 1) How do I subnet? (I need a specific example) Like Yasir mentioned, incrementing the borrowed sub-net bits allows you to create literally thousands of your own networks in Yasirs example, the 10.10.1.0 uses the mask 255.255.255.0 (the "255" means "match these bits" while the "0" means "these bits can be anything") So follow his guide for your VLANs and you should be ok.. 2) Do I need another router for subnetting? Subnetting is easily performed by really most of todays routers/ switches / firewalls etc. To be able to send data BETWEEN your newly-created VLANS does require some type of Layer 3 device (typically a router or device with routing capabilities) 3) We have Cisco 2950 switches on the LAN. I know VLANS can be created on the switches. How do I do the VLANS? On Cisco devices, VLANs are simple: Switch(config)# VLAN 10 Switch(config-vlan)# Name MyVLAN Switch(config-vlan)# exit - creating the VLAN is done. From here, you can add ports to the VLAN 4). At time the switches just hang requiring a reboot. What could be the cause? What IOS version are you running? do a "SHOW VERSION to see what IOS you have, and possibly updating the IOS may help in the hang-ups...
