How do I load EtherChannel balance?
Load balancing is possible between the links that are part of the same EtherChannel. Depending on the hardware platform, you can implement one or several methods, such as source-MAC to destination-MAC or source-IP to destination-IP load balancing across the physical links.
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.
How does LACP load-balance?
Load Balancing in LACP Mode To prevent out-of-order packets, Eth-Trunk uses flow-based load balancing. This mechanism uses the hash algorithm to calculate the address in a data frame and generate a hash key based on which the system searches for the outbound interface in the Eth-Trunk forwarding table.
What is the maximum number of ether channels that can be created on a Cisco device?
EtherChannel Feature Overview Cisco IOS Release 15.4SY supports a maximum of 512 EtherChannels. You can form an EtherChannel with up to eight compatibly configured LAN ports on any switching module.
Which two load balancing methods can be implemented with EtherChannel technology?
What are two load-balancing methods in the EtherChannel technology? (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.
How many ports we can Bundled in EtherChannel?
Each EtherChannel can consist of up to eight compatibly configured Ethernet ports. All ports in each EtherChannel must be configured as either Layer 2 or Layer 3 ports. The number of EtherChannels is limited to 48.
Do port channels load balance?
The port-channel load-balance command specifies the seed for hashing algorithms that balance the load across ports comprising a port channel. Available seed values vary by switch platform. This command configures the hash seed of 10 on 7150 Series (FM6000 platform) switches.
What are the two load balancing methods?
There are two primary approaches to load balancing. Dynamic load balancing uses algorithms that take into account the current state of each server and distribute traffic accordingly. Static load balancing distributes traffic without making these adjustments.
When EtherChannel is configured which mode will force?
When EtherChannel is configured, which mode will force an interface into a port channel without exchanging aggregation protocol packets? Answers Explanation & Hints: For both LACP and PAgP, the “on” mode will force an interface into an EtherChannel without exchanging protocol packets.
What port numbers can be used for load balancing on EtherChannel?
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. The mode you select applies to all EtherChannels that you configure on the switch.
What is the use of EtherChannel?
Etherchannel is a way to fool STP in a way that you can have up to 8 non blocked links connected from one switch to another (or from switch to server, as we can do that too). We have 2 flavors of Etherchannel protocol. One is Cisco proprietary PAgP (Port Aggregation Protocol).
What does the information in the document apply to all etherchannels?
The information in the document applies to all of these EtherChannels. This document presents the concept of load balancing and redundancy on Cisco Catalyst switches with the use of the EtherChannel. This document also covers the Port Aggregation Protocol (PAgP) and trunking support over EtherChannel.
How many ports can a switch have in an EtherChannel?
Etherchannel can have up to 8 ports, so number of links like 3, 5, 6 and 7 would never have equal distribution. Here is why and this is point where we are not able to influence: The switch is using per flow balancing because this is the way how hardware works.
