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.
What are some of the restrictions of an EtherChannel?
A limitation of EtherChannel is that all the physical ports in the aggregation group must reside on the same switch except in the case of a switch stack, where they can reside on different switches on the stack.
What are the requirements for interfaces participating in EtherChannel link aggregation?
Prerequisites of Enabling EtherChannel
- EtherChannel bundle links must be of the same type and speed.
- All links intended to be bundled MUST NOT exceed the number of eight physical links.
- All links MUST belong to the same VLAN if used as access links.
What is the maximum number of interfaces that can be aggregated with 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.
Should you use link aggregation?
When it comes to networking, a wired connection is always the best one. When one connection isn’t enough however, link aggregation or bonding two network connections together can boost throughput. Games don’t use much bandwidth so a 1 gigabit connection is enough, but link aggregation can help with file transfers.
What is EtherChannel AIX?
ETHERCHANNEL: EtherChannel is a trademark registered by Cisco Systems and is generally called multi-port trunking or link aggregation. If your Ethernet switch device has this function, you can exploit the support provided in AIX.
Is EtherChannel considered to be a Layer 2 or Layer 3 technology?
A layer 3 etherchannel is similar to an interface on a router. The switch won’t “switch” traffic on this interface but route it. Because it’s a layer 3 interface, we configure an IP address on it. If you forget to run the no switchport command on an interface, your etherchannel will be layer 2 instead of layer 3!
Why do we need STP?
The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. In 2001, the IEEE introduced Rapid Spanning Tree Protocol (RSTP) as 802.1w.
Can I delete default VLAN if deleted what are the effects?
Unfortunately, the default VLAN 1 is not allowed to be removed. Hi Truyen, Also please be advised that once you configure the switch port with with “trunk-no-default-native” mode, you will have to re-tag all of your previous VLANs as they are removed anytime you change the switch-port mode.
What is aggregated Ethernet interface?
IEEE 802.3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. Aggregating multiple links between physical interfaces creates a single logical point-to-point trunk link or a LAG.
What is the difference between EtherChannel auto and desirable modes?
What is the difference between EtherChannel auto and desirable modes? Desirable will always initiate autonegotiation, whereas auto will not. Auto will always initiate autonegotiation, whereas desirable will not. Auto will always try to negotiate to an access port first before trying other modes.
