I have a 3Gb layer-2 ether-channel between (2) 6509s running IOS. It currently runs at about 2.5Gb during peak hours.
What I've noticed though is that utilization on the individual links is not equal. 2 run at about 95% while the third runs at 80% during peak. I am in the process of adding additional links but am wondering why this would occur.
No load-balancing for the channel has been configured, so here is what it is defaulted to:
EtherChannel Load-Balancing Configuration:
EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source XOR Destination MAC address
IPv4: Source XOR Destination IP address
IPv6: Source XOR Destination IP address
Any feedback would be appreciated.
