Trunk traffic distirbution

I am new to HP switches and I am looking for command like "port-channel load-balance src-dst-ip" in Cisco for ProCurve 2900 or to know how this switch will load balance traffic in L2 etherchannel

TIA

Re: Trunk traffic distirbution

They load balance by Souce-Address/Destination-Address pairs only.

There are no configuration options available to change this.

Basically, the more active conversations you have between different hosts, the better the load balancing will be.

Ok
but does it based on ip address or mac address.

Re: Trunk traffic distirbution

From what I understand, they primarily load balance via SA/DA mac-address, however if 'ip routing' is enabled, they then load balance via SA/DA IP address (I'm not sure if this is instead of or in combination with mac-addresses). I've never tested and verified this 2nd method myself, but can see situations where it would definitely be required (e.g. a point to point L3 trunk link between routers)
