Question: What Is Difference Between Port Channel And Etherchannel?

vPC peer-link failure If peer-link fails, then all the member ports from vPC secondary node will be suspended.

Here important to note, keep-alive is active in this scenario, which allowing nodes to exchange heartbeat..

Does EtherChannel increase bandwidth?

Benefits of using EtherChannel Increased Bandwidth: Use EtherChannel and combine two or four links into one logical link. It will double or quadruple your bandwidth. For example, four 100Mb Fast Ethernet connections bonded into one could provide you up to 800Mb/second, full duplex.

What is ether channel and port channel?

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.

What is the difference between port channel and vPC?

vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a Port-Channel across multiple switches (i.e. vPC peers). … However, the key difference between vPC and VSS is that VSS creates a single logical switch.

What is difference between EtherChannel and link aggregation?

Cisco EtherChannel It’s become a generic term used that is often used interchangeably with the more correct term, link aggregation. While link aggregation is the term used to describe the overall technology, EtherChannel is a Cisco proprietary method for actually configuring link aggregation on Cisco equipment.

Should I use LACP or PAGP?

Both LACP and PAGP protocols are used for link aggregation. … Besides, LACP can support cross-stack, while PAGP does not since it does not support participating interfaces on different physical switches. Thus if you need to form the Etherchannel on stack switch, it is better to choose LACP instead of PAGP.

What are two advantages of using LACP?

What are two advantages of using LACP? (Choose two.)It allows directly connected switches to negotiate an EtherChannel link.It eliminates the need for configuring trunk interfaces when deploying VLANs on multiple switches.It decreases the amount of configuration that is needed on a switch.It provides a simulated environment for testing link aggregation.More items…•

Link aggregation offers the following benefits:Increased reliability and availability. If one of the physical links in the LAG goes down, traffic is dynamically and transparently reassigned to one of the other physical links.Better use of physical resources. … Increased bandwidth. … Cost effectiveness.

What is the use of port channel?

A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can bundle up to eight individual active links into a port channel to provide increased bandwidth and redundancy. Port channeling also load balances traffic across these physical interfaces.

What are port channels?

A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can bundle up to eight individual active links into a port channel to provide increased bandwidth and redundancy. Port channeling also load balances traffic across these physical interfaces.

How do I find my port channel?

To view the port channel’s status and channel members in a tabular format, use the show interfaces port-channel brief command in EXEC Privilege mode, as shown in the following example.

How does LACP protocol work?

LACP, a subcomponent of IEEE 802.3ad, provides additional functionality for link aggregation groups (LAGs). Use the link aggregation feature to aggregate one or more Ethernet interfaces to form a logical point-to-point link, known as a LAG, virtual link, or bundle.
