How can I modify my EtherChannel protocol
The basic procedure for configuring your EtherChannel interfaces are as follows:
- Connect with the command-line interface, (CLI), to your switch.
- Access Privately Enabled EXEC Mode.
- Access Global Configuration mode.
- Access Interface Configuration mode.
- Change switchport trunk or access, but all ports need to be in the same VLAN.
What is difference between port channel and EtherChannel?
“EtherChannel” or “Link Aggregation” is the particular technology that allows you to bundle several links between two devices and use them simultaneously as a single interface. This virtual interface is called “Port-channel” in IOS.
What are port channels used for?
A port channel is a communication channel between two switches that are supported by channel group interfaces. A port channel can also be called a Link Aggregation group (LAG). Port channels combine multiple Ethernet ports’ bandwidth into one logical link.
Does EtherChannel increase bandwidth?
Benefits from EtherChannel increased bandwidth: Use EtherChannel to combine two or four links into a single logical link. It can double or quadruple the bandwidth. Load Balance Traffic: EtherChannel balances traffic loads across links to increase efficiency and improve network performance.
Does EtherChannel load balance?
EtherChannel Load-Balancing Options. EtherChannel balances traffic between links within the bundle. Frames can be forwarded via an EtherChannel link based on a hashing algorithm.
Does lag increase bandwidth?
Incremental growth in bandwidth. An upgrade to a physical server could result in a tenfold increase in bandwidth. LAG, on the other hand, can provide a two- to fivefold increase. This is useful for small increases.
What are three advantages of using EtherChannel technology?
What are the three benefits of EtherChannel technology use? (Choose three.) *EtherChannel has multiple logical links that provide redundancy. *Configuration tasks are possible on the EtherChannel interface. *There’s no need to upgrade links to improve bandwidth.
What are two load balancing methods in the EtherChannel technology?
These methods include source MAC-destination MAC load balancing and source IP-destination IP load balancing across physical links.
What are two requirements to be able to configure an EtherChannel between two switches?
What are the two requirements for being able to configure EtherChannels between two switches? (Choose two. )
- All interfaces must work at the same time.
- All interfaces must be assigned to different VLANs.
- Different allowed ranges of VLANs must exist on each end.
Which two issues are the result of a broadcast storm choose two?
Which of these two issues is caused by a broadcast storm. Communication between broadcast domain stations may be disrupted by high processing requirements during a broadcast storm. During a boardcast storm, changes to the MAC address list can prevent a switch from correctly forwarding frames.
Which switch becomes the root bridge?
If all the switches in a single spanning branch have the same bridge priority then the switch with lowest MAC address will be the root bridge. This diagram shows that Switches D, B and C comprise the core network. Switch A and Switch C are the access layer switches.
How is bridge ID calculated?
Every switch in a network has an identity. This identity is known as the Bridge ID, or BID. It is 8 bytes in size and is broken into two parts. The first part of the field is a 2-byte Bridge Priority Field (which can be configured), while the second is the 6-byte MAC Address of the switch.
What is the root bridge?
A Root Bridge serves as a point of reference for all switches within a spanning tree topology. A process of election takes place across all connected switches. The Root Bridge with the lowest Bridge ID is elected.
What is the difference between root ID and bridge ID?
An election determines which switch will become the root bridge. Each switch is assigned a Bridge ID (BID). This ID is composed of a priority value and an extended system ID. It also includes the MAC address. All switches on the network participate in the election process. Root ID is used to identify the root bridge in the network.
Which benefit to a LAN does a switch provide?
- Increased network scalability–The network can expand easily as the business grows.
- Improved bandwidth performance for every network user–This is critical in environments where users use multimedia applications or interact with clients/server databases frequently.
What creates a switching loop?
A switching loop or bridge loop is a loop that connects two ends of a computer network. Multiple connections can be made between two switches on a network or two ports connected to the same switch.
What is STP loop?
The Spanning Tree Protocol is a protocol for creating a topology that is free from loops in Ethernet networks. STP’s primary function is to avoid bridge loops and the radio radiation that they generate.
