Virtual Local Area Network (VLAN) configuration:
VLAN is a technology that divides a physical network into multiple logical subnets. By configuring VLANs, you can isolate broadcast domains so that even in a physical network, different VLANs can have their own independent broadcast domains. This not only reduces broadcast traffic in the network and improves network performance, but also enables more fine-grained network access control by dividing different users or departments into different VLANs. For example, you can assign the sales department to VLAN 1 and the finance department to VLAN 2, so that users in each VLAN can only communicate with users in the same VLAN and cannot access data from other VLANs.
DHCP (Dynamic Host Configuration Protocol) configuration:
DHCP is a technology that automatically assigns IP addresses. By configuring DHCP, you can have devices in your network automatically obtain network parameters such as IP addresses, subnet masks, and default gateways, without having to manually set them for each device. This not only reduces the workload of network administrators, but also improves the efficiency of network device provisioning. For example, when a new device joins the network boots up, it can automatically obtain an IP address from the DHCP server without human intervention.
Route configuration: Routing refers to the process of selecting a path for packets as they travel through a network. By configuring routing, you can specify the path that packets take across multiple networks to ensure that the data reaches the destination address without errors. For example, let's say your corporate network has two subnets, each 192168.1.0 24 and 192168.2.0/24。You can configure the route to let it come from 192168.1.Packets from 0 24 subnets are sent to 192 through a specific interface168.2.0 24 subnets and vice versa.
STP (spanning tree protocol) configuration:
STP is a network protocol that is primarily used to avoid loops in a network. When the network is looped, the packets are transmitted in a loop, resulting in a network failure. STP uses the spanning tree algorithm to select the optimal path and disconnect the loop to avoid network failures. For example, if you have two switches in your network connected by a link, you can configure STP to make one switch the root node and the other switch the leaf node to avoid loops.
Link aggregation configuration:
Link aggregation is a technology that improves the bandwidth and reliability of a network. By configuring link aggregation, you can aggregate multiple physical links into a single logical link. In this way, even if one link fails, the other links can continue to transmit data, improving the reliability of the network. At the same time, because the bandwidth of the aggregated link is greater than the bandwidth of a single link, the upstream bandwidth of the network is also improved. For example, if your server needs to be connected to the core network via an uplink, you can configure link aggregation to aggregate two 1Gbps links into one 2Gbps logical link. In this way, even if one link fails, the other link can continue to transmit data, while the overall upstream bandwidth is improved.
