What Load Balancing Method Can Be Implemented With EtherChannel Technology? Depending on the hardware platform, one or more load-balancing methods can be implemented. These methods include source MAC to destination MAC load balancing or source IP to destination IP load balancing, across the physical links.
What is the mode of load balancing for etherchannels?
EtherChannel load balancing can use MAC addresses or IP addresses, source or destination addresses, or both source and destination addresses. The mode applies to all EtherChannels that are configured on the switch.
How many load-balancing methods are there?
(Choose two.) Depending on the hardware platform, one or more load-balancing methods can be implemented. These methods include source MAC to destination MAC load balancing or source IP to destination IP load balancing, across the physical links.
What is the Cisco-proprietary hash algorithm used for load balancing?
Catalyst 6500/6000 switches that run Cisco IOS system software uses a Cisco-proprietary hash algorithm. This algorithm is explained in the Catalyst OS section. EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers with a Policy Feature Card 2 (PFC2) and either source mode, destination mode, or both.
What is the recommended number of links in an EtherChannel?
So to be consistent, the number of links should be in powers of two, 2, 4, 8, etc. Load balancing on a 3-port EtherChannel is not as effective as load balancing on a 2-port or 4-port EtherChannel. Changing the hash may result in a different distribution ratio among the links if they are unevenly distributed.
Which two load balancing methods can be implemented with EtherChannel?
There are two load balancing methods for outgoing traffic in EtherChannel, as follows: round-robin, which spreads the outgoing traffic evenly across all of the adapters in the EtherChannel; and standard, which selects the adapter using an algorithm.
How does load balancing work on EtherChannel?
EtherChannel load balances traffic across links in the bundle. However, traffic is not necessarily distributed equally among all the links. Frames are forwarded over an EtherChannel link that is based on results of a hashing algorithm. Options that switch can use to calculate this hash depends on the platform.
What are two load balancing methods in the ETA channel technology?
Weighted Response Time load balancing method load balancing method.
What are the two load balancing methods in third channel technology?
There are two significant types of load balancing algorithms: static and dynamic.
What are the types of EtherChannel?
There are 3 methods to configure EtherChannel in your network: the PAgP and LACP negotiating protocols, or Static mode.
How do I change my EtherChannel load balancing?
To change the load-balancing method for your switch, use port-channel load-balance and verify with show etherchannel load-balance. This is a global command – you can't change the load balancing method on a per-port or per-EC level. The “XOR” choices balance on source and destination IP or source and destination MAC.
What are two load balancing methods in the EtherChannel technology?
Load balancing takes place between links that are part of the same EtherChannel. Depending on the hardware platform, one or more load-balancing methods can be implemented. These methods include source MAC to destination MAC load balancing, or source IP to destination IP load balancing, across the physical links.
What are two load balancing methods in the EtherChannel technology choose two combination of source port and IP to destination port and IP?
Explanation: Source MAC to destination MAC load balancing and source IP to destination IP load balancing are two implementation methods used in EtherChannel technology.
What are the types of load balancing?
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use these types of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.
What is the default load balancing configuration for EtherChannel?
The default load-balancing method for a Layer-2 EtherChannel is either src- mac or src-dst-mac, depending on the platform. The default method for a Layer-3 EtherChannel is src-dst-ip. The load is rather cryptically represented in a hexadecimal value.
What is round robin algorithm for load balancing?
What Is Round-Robin Load Balancing? Round‑robin load balancing is one of the simplest methods for distributing client requests across a group of servers. Going down the list of servers in the group, the round‑robin load balancer forwards a client request to each server in turn.
What are three advantages of using EtherChannel technology?
*EtherChannel uses multiple logical links to provide redundancy. *Configuration tasks can be done on the EtherChannel interface. *There is no need to upgrade links to faster connections to increase bandwidth. *Load balancing is not needed with EtherChannel.
How do I load a port channel balance?
To configure load balancing for port channels, use the port-channel load-balance command in switch configuration mode. To restore the default configuration, use the no form of this command.
What is the difference between LACP and EtherChannel?
EtherChannel vs. Both technologies are capable of automatically configuring this logical link. EtherChannel supports both LACP and Cisco's PAgP, whereas 802.3ad uses LACP. LACP allows for up to 8 active and 8 standby links, whereas PAgP only allows for 8 active links.
Should I use LACP or PAGP?
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.
How does OSPF load balancing Work?
Like other dynamic routing protocols, OSPF does equal cost load balancing, and if you have routes with equal cost paths to the same destination, then OSPF will do load sharing. Unlike Enhanced Interior Gateway Routing Protocol (EIGRP), OSPF can't do unequal cost load balancing.

Load Balancing: How to Determine The Link Across Which to Send Traffic
- This section explains the load balance of packets over an EtherChannel group for each switch platform.
Restrictions
- This section contains usage guidelines, restrictions, and troubleshooting information that apply to EtherChannel: 1. The WS-X6548-GE-TX, WS-X6548V-GE-TX, WS-X6148-GE-TX, and WS-X6148V-GE-TX modules have a limitation with EtherChannel. EtherChannel is supported on these modules for all configurations (10, 100, and 1000 Mbps speeds) but be aware of these cases of oversubscrip…
What Is PAGP and Where Do You Use It?
- PAgP aids in the automatic creation of EtherChannel links. PAgP packets are sent between EtherChannel-capable ports in order to negotiate the formation of a channel. Some restrictions are deliberately introduced into PAgP. The restrictions are: 1. PAgP does not form a bundle on ports that are configured for dynamic VLANs. PAgP requires that all ports in the channel belong …
/802.1Q Trunking Support on Etherchannel
- You can configure EtherChannel connections with or without Inter-Switch Link Protocol (ISL)/IEEE 802.1Q trunking. After the formation of a channel, the configuration of any port in the channel as a trunk applies the configuration to all ports in the channel. Identically configured trunk ports can be configured as an EtherChannel. You must have all ISL or all 802.1Q; you cannot mix the two. ISL/…
