Layer 3 switches can route packets amongst numerous subnets or VLANs (virtual LANs) with the appliance of IP addresses, just like the way wherein networking products referred to as routers handle them. For this reason They may be well suited for large-sized networks necessitating fast switching together with routing capabilities.
When talking about the purpose of networking and the necessity บริษัท รังรอง จำกัด for layers two and 3 switches, one particular cannot dismiss their great importance so far as connection separation and routing is worried. Also, there are actually other functions like Electric power more than Ethernet (PoE) and modularity that provide more flexibility in the event an software demands a little something unique.
Configuration management resources resolve this by offering configuration equipment that span บริษัท รังรอง จำกัด over the total network. Additionally they make it possible for network managers in order that all compliance specifications are already fulfilled.
Continuous recording ensures that each and every second is captured, making certain no function goes unnoticed. However, movement-centered recording only starts off recording when motion is detected, optimizing space for storing and which makes it much easier to critique precise incidents.
