L2/L3/L4 Switch简介 第二层交换机,是根据第二层数据链路层的MAC地址和通过站表选择路由来完成端到端的数据交换的。因为站表的建立与维护是由交换机自动完成,而路由器又是属于第三层设备,其寻址过程是根据IP地址寻址和通过路由表与路由协议产生的。所以,第二层交换机的最大好处是数据传输速度快,因为它只须识别数...
This tracking SLA policy config works great on L3 switch! Make sure the port that will be use on L3 switch is set to routed port instead of trunking betwn two locations. Use L3 subnet to create PPP link. ip route 0.0.0.0 0.0.0.0 5.5.5.2 <ip route 4.4.4.0 255.255.255.0 int...
This L3 engine is provided by the Nexus Core Switch (which must have an appropriate Layer 3 image and license). On the Core Switch, for each Layer 2 vlan we will configure an SVI (Switch Virtual Interface) which will serve as the default gateway for all hosts connected to that particular...
L2其实是指七层网络协议中的第二层数据链路层,它的传输是以mac地址为基础 L3指网络层:是以ip地址为基础 网络层属于OSI中的较高层次了,从它的名字可以看出,它解决的是网络与网络之间,即网际的通信问题,而不是同一网段内部的事。网络层的主要功能即是提供路由,即选择到达目标主机的最佳路径,并沿该路径传送数据包。
ECS4125-10P L2+/L3 Lite Switch L2+/L3 Lite 2.5G Ultra PoE++ Switch ECS4125-10P The Edgecore ECS4125-10P switch is a 2.5 Gigabit Ethernet access switch with two 10G uplink ports. The switch is an ideal 2.5 Gigabit PoE access switch for SMB, enterprise, and campus networks. The ECS...
Multi-Nets NAT function can help TP-Link SMB router provide NAT translation for multiple subnets. And in order to divide an internal network into several subnets, a L2+/L3 switch is needed. Application Scenario Let’s take an example to explain in detail. A company has three departments in...
The PC sits on VLAN 1 and can ping any switch on it's network. The PC can also ping any VLAN on the L2 switch it is connected to. But it cannot ping the next hop on a different VLAN 192.168.20.251. (Can ping VLAN1 on the next hop though). Core is a L3 switch and the W...
