cisco layer 2 switch models

server and the client are in the same network segment and are not DHCP relay agents, for Cisco's DHCP In the case of a server, if a request packet with Option82 is received, it is considered a request message from a DHCP relay agent, and the Giaddr field of the message is checked, but because it belongs to the same network segment, the field is 0.0.0.0 DHCP. The server will consider an illegal address, and this message will be discarded, causing the client to obtain no IP address(iv)

of using Server Load balancer to improve the scalability, availability, and manageability of Server clusters. This chapter mainly discusses the deployment of Server Load balancer and several solutions for deploying Server Load balancer in the existing network. We will also discuss how to design highly available solutions to implement fault tolerance for different network components throughout the network, including Load balancer. Before discussing the network structure, we need to understa

to say, after you set the password for level 1, you will be asked to enter the password next time you connect to the switch and enter K, this password is the password set for level 1. Level 15 is the privileged mode password that you enter after you enter the enable command. Step 2: Set the VLAN name. Because the four VLANs belong to different switches, the command for VLAN naming is VLAN 'vlan No. 'name'

Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth. Three-tier competition
