meraki layer 3 switch

Layer-3 egress connection to the internal port of the firewall It is recommended that layer-3 core switches use VLAN1 to connect to the firewall's internal port. The Intranet access to the Internet may be slow due to IP redirection !! The specific examples and solutions are as follows: The core of a certain Enterprise

255.255.255.0 PC1 (config-if) # exit PC1 (config) # ip default-gateway 192.168.10.254 [PL2] PC2 (config) # no ip routing PC2 (config) # int f0/0 PC2 (config-if) # no sh PC2 (config-if) # ip address 192.168.20.1 255.255.255.0 PC2 (config-if) # exit PC2 (config) # ip default-gateway 192.168.255.254 5.

This function is equivalent to executing vlan 200, ip address 192.168.200.1 255.255.0 on a layer-3 switch. Configurations on L2 Switches The configuration on the L2 Switch is the same as before. Take AVAYA P334 as

There are many things worth learning about layer-3 router switches. Here we mainly introduce the solutions to soft faults in layer-3 router switches. Two days ago, our company's network was upgraded, and the core device adopted the INTEL550 series L3 route switch. The 500 se

Idea: Configure The VTP host and client, enable IP routing, and divide VLAN -----> define IP addresses for each VLAN port, and enable trunk ------> enable DHCP on The vtp server, and define IP-pool, set different CIDR blocks to VLAN interface IP addresses as gateways ------> Add ports to corresponding VLANs -------> set management IP addresses and passwords of vswitches 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/4C/42/wKiom1Q6Ms_AiVU2AAH5SP-f5do600.jpg "Title =" Capture 2.jp

The h3c layer-3 Switch acl is an example of a new library that can only access the electronic reading room, and cannot access other hosts on the Intranet, so as to avoid security impact. the IP address of the On-Internet www.2cto.com electronic reading room is not opened to 10.0.1.9, the new library plans to divide vlan 11, network segment 10.1.11.0/25, and vlan-

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 192.168.1.2 255.25

Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the Mac in the packet Address information, forwarding based on MAC addresses, and recording these MAC addresses with corresponding ports in one of their own. Address table. The specific work flow is as fol

Today, the tutor told me about the company's network topology, related to the switch, the basic concept of routers and principles, I am not very clear, so on the internet to learn the information to learn a bit, and then feel that this article is good, so it reproduced, but I reproduced not the original text, and did not attach the original link. Here I posted a link to my reprinted article: http://blog.csdn.net/herostarone/article/details/8256235 Two

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same

Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC addresses and corresponding ports recorded in their own internal table of addresses.

" IP address broadcast an ARP request, if the third switch module in the previous communication process has obtained B's MAC address, then to send station a reply to B's MAC address; otherwise the third Layer switch module broadcasts an ARP request to the destination station based on the routing information, and B gets the ARP request to The third
