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.hen an EtherChannel is configured all adapters that are part of the channel share the same Layer 2 (MAC) address. This makes the EtherChannel transparent to network applications and users because they only see the one logical connection; they have no knowledge of the individual links.

Increase network bandwidth using Cisco's EtherChannel EtherChannel allows you to achieve greater speed by bundling Fast Ethernet or Gigabit Ethernet links, which makes a switch or router use the merged ports as a single port. This gives you the most bang for your buck from your port cost. EtherChannel uses a Cisco-proprietary hashing algorithm to achieve this link bonding. EtherChannel can be configured on many different switch platforms such as the 6500/6000, 5500/5000, 4500/4000, and 2950/2960 series. In this article, I'm going to focus on how to configure EtherChannel on the 2950/2960 line of switches because those are some of the most deployed and well-known platforms.

EtherChannel Concepts and Deployment Spanning-tree reflects the increased bandwidth provided by EtherChannel. The default cost for a 100 Mbps link is 19 and if a port-channel is created that has only two 100 Mbps links the spanning-tree cost will be 9. If more physical ports are assigned to the port-channel the cost decreases.

What is Etherchannel in Cisco Switches and Routers, What is Link Aggregation and what are PAgP LACP EtherChannel is a port link aggregation technology developed by Cisco, which provides fault-tolerant high-speed links between Switches, Routers, and Servers. EtherChannel technology allows multiple physical Ethernet links (Fast Ethernet or Gigabit Ethernet) to combine into one logical channel.he main advantages of EtherChannel technology is that it allows load sharing of traffic among the links in the channel as well as redundancy in the event that one or more links in the EtherChannel fail. EtherChannel is a Cisco Copyrighted term and the term which industry adopted is Link Aggregation.

Cisco Catalyst 3850 Series Switches FAQ When a new Cisco Catalyst 3850 (Switch 4) is added to the stack with an access point count license of 25 access points, the total access points supported by the stack equals 50, since the total (30+25) 55 exceeds the stack limit.. The Cisco Catalyst 3850 comes with a 10/100 Ethernet dedicated management port on the backside of the switch right above the console port. This port is in separate VRF called “Mgmt-vrf.” This is to segment the management traffic from the global routing table of the switch.

- EtherChannel reduces part of the binary pattern that is formed from the addresses in the frame to a numerical value that selects one of the links in the channel in order to balance the traffic load across the links in a channel.hen you enable UplinkFast, the EtherChannel port path cost, which you set with the set channel cost command, for a 4-port 10/100 EtherChannel is less than the port path cost of a parallel Gigabit Ethernet link. This situation causes the slower 4-port EtherChannel to forward and the Gigabit Ethernet link to block.
