How do you verify available load balance methods?
port-channel load-balance ?
How do you achieve optimal traffic distribution?
always bundle an even number of links
What must match for all interfaces on a EC?
- Interface speed of duplex
- Interface trunking mode and VLANs
- Layer on which an interface operates
How do you check the distribution algorithm?
show etherchannel load-balance
How do you check traffic statistics?
show etherchannel traffic
What is Etherchannel guard?
used to detect EC misconfigurations, enabled by default
It is a common misconception that the load balancing among links in the channel is equal. Load balancing depends on the ___and the number of __ in the channel.
traffic distribution algorithm, number of interfaces
