5 things to keep in mind while shopping a laptop…

  1. Analyze your requirements: It doesn’t make sense to buy one with an i7 processor if you are a frequent traveler whose sole purpose of a laptop is surfing the net or making presentations. But a 9 cell battery instead of the standard 6 cell will save you frequent plug-ins!
  2. The keypad size: Make sure the size of the keypad suits your finger-size.
  3. The heat vents: Those having the air vents on the sides provide better cooling and are more healthier when used on laps, than those with air vents below.
  4. Indicator Lights: Choose systems that have physical indication lights over monitor indicators for Caps Lock, Wi-Fi, etc. This provides for better troubleshooting.!
  5. Warranty and after-sales support: Choose brands that are well known for after-sales support. Some brands provide next-business-day support and even get your laptops serviced by an engineer visiting your home, rather than you taking your device to the service-center.

Different Internet Gateways for Different VLANs…

One day, my dad came up with a problem in his office network. They were upgrading the network infrastructure, and in doing so, had to assign different Internet gateways for each VLANs and also had to perform inter-VLAN routing using an L3 switch. He himself had a solution and asked me about it. I said, ‘yeah it should work for sure’. The solution was,

  • Assign the respective Internet gateway IPs as the default gateway of the respective VLAN PCs. This way, each user has access to the Internet. (The Internet gateway a particular VLAN must use belongs to the same VLAN)
  • Now add a static route to each PC’s route table, to route all internal packets to the corresponding VLAN management IP. This makes way for inter-VLAN routing through the L3 switch.

route -p add 192.168.0.0 mask 255.255.0.0 192.168.10.1

This command adds a static route to the Windows route table, which says, route all packet that belongs to the 192.168.0.0/24 network or subnets to 192.168.10.1(which is the management IP of, say VLAN10)

Solved!!!
