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...
I am able to ping all other VLANs except one particular VLAN-VLAN100 . I've created multiple VLANS is L2 switch and connected it to L3 switch -Cisco 6506. Here are my config details .Kindly help where it went wrong. Should the VLAN names be same on both the switches My L2 switch ...
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。
TRANSMISSION METHOD, RECEIVING TERMINAL, AND L2 SWITCH, L3 SWITCH IN MULTICAST COMMUNICATION NETWORKPROBLEM TO BE SOLVED: To enable multicast packets to be delivered selectively only to a designated receiving terminal in a network whose system containing an L2 switch.UCHIYAMA MOTOHIRO...
When the PPP link restored on the L3 switch the LAN traffic continue to pass through the tunnel. How do I configure the firewall or the switch to drop the IPSec tunnel when the PPP link restore? The trick here is my internet ASA5520 firewall at both sites doesn’t know this...
Solved: On a layer 3 switch on issuing the global command ip routing the L3 is enabled and intervilan routing is enabled. Can I have some ports of same switch as L3 and some as L2?
