What is the correct command for configuring load balancing on an EtherChannel link?
Use the following command to configure frame distribution for all EtherChannel switch links: Switch(config)# port-channel load-balance method Notice that the load-balancing method is set with a global configuration command. You must set the method globally for the switch, not on a per-port basis.
What is port channel load balance?
Traffic in a port channel is distributed across the individual bundled links in a deterministic fashion. However, the load is not necessarily balanced equally across all of the links.
Does EtherChannel provide redundancy?
Benefits of using EtherChannel Provides Redundancy: Since there are many Ethernet links combined into one logical channel, it automatically allows more available links in case one or more links go down.
How do I check Cisco EtherChannel status?
Use the command, show port-channel summary, to verify the number of port-channels already configured. You can have a maximum of 256 port channels on the Cisco Nexus 1000V. Use this procedure to force the physical interface to take on the characteristics of the port channel.
What is EtherChannel configuration?
An EtherChannel consists of individual Gigabit Ethernet or 10-Gigabit Ethernet links bundled into a single logical link as shown in Figure 1. Up to eight ports can be configured, and all of these ports should be the same type (Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet). …
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 is port channel vs EtherChannel?
Port channel vs Etherchannel –
|Cisco’s way of distinguishing||Port-channel is the name of Cisco’s virtual interface for the purpose of Link aggregation||Etherchannel is a term used by Cisco to describe a link aggregation|
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.
What is LACP and PAGP?
LACP stands for Link Aggregation Control Protocol. While PAGP stands for Port Aggregation Protocol. IEEE Standard. The IEEE standard of LACP is IEEE 802.3ad. Etherchannel.
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.
How do I balance traffic across EtherChannel using an etherhash?
Hashes are also used to balance the traffic across etherchannel. By default Layer 2 packets are distributed on XOR computation of source and destination MAC address and Layer 3 packets based on XOR source and destination IP address: OK, we have our default load balancing algorithm in place.
How do I check the frame distribution policy of EtherChannel?
Issue the show etherchannel load-balance command in order to check the frame distribution policy. You can determine which interface in the EtherChannel forwards traffic, with the frame distribution policy as a basis.
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.
