bound together, multiply the bandwidth of the link. Link aggregation technology can achieve load balancing of different ports, and also backup each other to ensure link redundancy. In some Gigabit Ethernet switches, a maximum of four link aggregation groups are supported, and each group has a maximum of four ports. Both the Spanning Tree Protocol and link aggregation can ensure the redundancy of a network. Set redundant links in a network and use the Spanning Tree Protocol to block the backup l

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assu

Layer-3 Switch ACLs are used to isolate different VLANs. Create three VLANs: vlan10 vlan20 vlan30 www.2cto.com PC1 PC3 vlan10 PC2 PC4 vlan20 PC5 vlan30Vlan10 vlan20 vlan30 cannot communicate with each other but can access the Internet Pc1: 172.16.10.2 pc2: 172.16.20.2 pc3: 172.16.10.3 pc4: 172.16.20.3 pc5: 172.16.30.2 configure R1Int f0/0Ip add 192.168.1.2 255.255.255.0 configure f0/0No shInt lo0Ip add 1.1.

The security switch mainly uses the access control list to implement the security function of the packet filtering firewall. It enhances the security protection capability and is the first choice for small and medium-sized enterprises. Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core security switch also takes responsibility for network security. Ther

Sometimes I think ACL is a depressing technology, because different vendors, brands, and even models have different settings for the last ACL rule. Recently the school's younger brother to use ruijie three-layer switch 3760-24 and router RSR20-04 to participate in the Guangzhou Computer Skills Competition, but was ruijie ACL confused. Due to technical vulnerabilities and chaotic rules in the ACL of ruijie exchange routes, after all, it is a domestic m
