Switch Basics: Link Aggregation definition
Link aggregation technology is also known as backbone Technology (trunking) or bundled technology (bonding), its essence is to two devices between several physical link "combination" int
5. Configure link AggregationDescription: DELL 5524 switches can be used to create link aggregations manually, or you can use the LACP protocol for link Clustering Hop. Switch 19-20 port set to static link aggregation, 21-22
Active mode; passive1) The LACP protocol of the Start port, and set it to Passive mode; on2) force the port to join the PortChannel, do not start LACP.
For example, in port Ethernet0/0/1 mode, add this port to port-group in active mode.
SwitchConfig-Ethernet0/0/1) # port-group1modeactive

Microsoft's Windows Server 2012 has been able to support LACP link aggregation, due to the use of link aggregation can achieve line redundancy and bandwidth increase, here I used a Cisco 2960 to do a test for interested friends reference.Experiment Preparation:Cisco switch 2
Lab Requirements:The dual-core architecture combines three-layer switching technology with VTP, STP, and Ethernet channels to achieve high-speed network conversion, high availability, high reliability and redundant backup functions, mainly for the network of dual-core topologies.Experimental design:1. Configure VLANs on the switch to control broadcast traffic.2. Configure the Ethernetchannel between the 2 three-layer switches to achieve high-speed int

The main switch can see all the network ports of the standby switchN
Original intention:
At the beginning of 2011, when I learned about the switch link aggregation technology, I had a question in my mind:
The switch receives a message, arrives at the aggregation mouth, how chooses the member mouth to go out?
Was it a random selection? or b
core exchange systems and networks with high-quality services. The following figure 4 shows an aggregation link between the IRF system X1 and X2. The physical connection of this link is Link1 ~ Link4 is responsible for communication between LAN1 and lan2. If the X11 switch in X1 fails, the Link1 and Link2 are unavaila
link larger than 10 Gbit/s, you can aggregate two 10 Gbit/s links to obtain a transmission line with a bandwidth greater than 10 Gbit/s.
In addition, the capacity of transmission lines needs to be limited in a specific networking environment, which neither affects transmission speed nor exceeds the processing capability of the network. However, existing technologies only support the increase of link bandwi
The three concepts of link aggregation (link Aggregation), trunk, and port binding/bundling are easy to confuse, with the main thrust being to provide reliability between servers, switches, and storage using link redundancy, or load balancing with redundant ports, often in t
Brief introductionLink aggregation (link Aggregation), refers to a number of physical ports bundled together to become a logical port to achieve the load sharing of the outgoing/incoming traffic in each member port, the switch based on the user-configured port load sharing strategy determines which member port from whi
If there is no port aggregation on the vswitch. Your two computers are connected with two network cables. It turns into a ring, which affects both the switch and the connected computer. Therefore, the port aggregation function is crucial for Internet cafe switches.
This section briefly describes information about the port ag
use the MAC address of Network Card 1. Because mac1 is no longer on the network, the data packets will not be received by any network card. Therefore, after ENI 2 takes over the master role, it is best to have a callback event. When processing this event, it will have a free ARP broadcast and broadcast itself to change the MAC address.Lacp_rate:Send the lacpdu of 802.3ad so that the Peer device can automatically obtain link

R3 is a gateway, R4 is an egress router, and DHCP is used. R5 is a vro on the Internet.
Lab requirements: 1. Three PCs belong to three VLANs
2. R1 and R2 are used for Link aggregation.
3. The Gateway ends at R3 to implement
