What are two advantages of using LACP?

What are two advantages of using LACP?

It allows directly connected switches to negotiate an EtherChannel link. It provides a simulated environment for testing link aggregation. It decreases the amount of configuration that is needed on a switch. It allows the use of multivendor devices.

What is an advantage of Pvst +?

What is an advantage of PVST+? PVST+ requires fewer CPU cycles for all the switches in the network. PVST+ reduces bandwidth consumption compared to traditional implementations of STP that use CST. PVST+ optimizes performance on the network through autoselection of the root bridge.

What is a result of connecting two or more switches together?

Explanation: When two or more switches are connected together, the size of the broadcast domain is increased and so is the number of collision domains. The number of broadcast domains is increased only when routers are added.

Which type of traffic is designed for a native VLAN?

untagged traffic

What represents a set of routers that present the illusion of a single router to hosts?

Explanation: In FHRP multiple routers are configured to work together to present to hosts a single gateway router. This single gateway router is a virtual router which has a virtual IP address that is used by hosts as a default gateway.

What is Layer 3 redundancy?

ArubaOS 8.2. For Layer-3 redundancy to work, ensure that ICMP. ICMP is an error reporting protocol. It is used by network devices such as routers, to send error messages and operational information to the source IP address when network problems prevent delivery of IP packets.

What is the status of EtherChannel?

Based on the command output shown, what is the status of the EtherChannel? The EtherChannel is in use and functional as indicated by the SU and P flags in the command output. The EtherChannel is down as evidenced by the protocol field being empty.

What is requirements to configure a trunking EtherChannel between 2 switches?

What is a requirement to configure a trunking EtherChannel between two switches?

• The allowed range of VLANs must be the same on both switches.
• The participating interfaces must be assigned the same VLAN number on both switches.
• The participating interfaces must be physically contiguous on a switch.

What are two advantages of EtherChannel?

What are two advantages of EtherChannel? (Choose two.)

• Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection.
• Load balancing occurs between links configured as different EtherChannels.
• Configuring the EtherChannel interface provides consistency in the configuration of the physical links.

What is the difference between PAGP and Lacp?

Both LACP and PAGP protocols are used for link aggregation. They are aimed at bundling the links and balancing traffic across the member links to provide aggregated throughput. LACP is open standard and supported by most of vendors, while PAGP is Cisco proprietary only used between Cisco devices.

Can an EtherChannel be a trunk?

On a Layer 2 switch, EtherChannel is used to aggregate access ports or trunks. For example, if the physical ports of one side are configured as trunks, the physical ports of the other side must also be configured as trunks. Each EtherChannel has a logical port channel interface.

How many ports can EtherChannel logically bundle?

eight

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. “Port-channel” is the name of this virtual interface in IOS.

How many ways can you configure EtherChannel?

For a PAgP EtherChannel, you can configure up to eight ports of the same type and speed for the same group. For a LACP EtherChannel, you can configure up to 16 Ethernet ports of the same type. Up to eight ports can be active, and up to eight ports can be in standby mode.

How do you configure VLAN?

First, VLAN support needs to be enabled on the switch if it is not already:

1. Choose Switch configuration.
2. Choose Advanced Features.
3. Choose VLAN Menu…
4. Choose VLAN Support.
5. Set Enable VLANs to Yes if it is not already, and choose a number of VLANs.
6. Restart the switch to apply the changes.

How do I change EtherChannel mode?

The basic process for configuring your EtherChannel interfaces is as follows:

1. Connect to the command-line interface (CLI) your switch.
2. Access Privileged EXEC mode.
3. Access Global Configuration mode.
4. Access Interface Configuration mode.
5. Change switchport to trunk or access, but all ports must be in the same VLAN.

Why do we use EtherChannel?

EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches. It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.

How many types of EtherChannel are there?

There are 3 methods to configure EtherChannel in your network: the PAgP and LACP negotiating protocols, or Static mode.

How many EtherChannel groups are there?

You can assign up to 16 physical interfaces to an EtherChannel but only 8 interfaces will be active at a time. If you want to configure an EtherChannel then we have three options: PAgP (Cisco proprietary)

What are port channels?

A port channel is a communication link between two switches supported by matching channel group interfaces on each switch. A port channel is also referred to as a Link Aggregation Group (LAG). Port channels combine the bandwidth of multiple Ethernet ports into a single logical link.

How many port channels can you have?

Maximum number of port channels reached for system. Use the command, show port-channel summary, to verify the number of port-channels already configured. You can have a maximum of 256 port channels on the Cisco Nexus 1000V.

Why do we need port channel?

A port channel does a couple of things: Increases the available bandwidth between two devices. Creates one logical path out of multiple physical paths. Since Spanning Tree Protocol (STP) runs on the logical link and not the physical links, all of the physical links can be in a forwarding state.

What is the difference between access and trunk port?

An access port is a connection on a switch that transmits data to and from a specific VLAN. A trunk port allows you to send all those signals for each switch or router across a single trunk link. In contrast to an access port, a trunk port must use tagging in order to allow signals to get to the correct endpoint.

How do I know if my interface is access or trunk?

Use the show interfaces trunk command to check whether the local and peer native VLANs match. If the native VLAN does not match on both sides, VLAN leaking occurs. Use the show interfaces trunk command to check whether a trunk has been established between switches. Statically configure trunk links whenever possible.

When should you use a trunk port?

When you implement multiple VLANs across a network, trunk links are necessary to ensure that VLAN signals remain properly segregated for each to reach their intended destination. This is also more efficient, as multiple VLANs can be configured on a single port.

What is difference between VLAN access and trunk mode?

An access port can have only one VLAN configured on the interface; it can carry traffic for only one VLAN. A trunk port can have two or more VLANs configured on the interface; it can carry traffic for several VLANs simultaneously.
