Trunked port vs each vlan on its own port

Hello everyone, 

 

We have 4 vlans on our network,  and a 3400 controller,  so 4 ports total.     Is it better as far as performance is concerned to trunk all 4 vlans to one port,   or to put each vlan on its own port?     I assume each to its own port would help remove a bottleneck,  but i'm wrong quite often! 

 

Thanks

Measure the utilization on that port and you would be suprised at the answer.

I'd recommend both assuming your switches are of a good new and solid type. Assuming your switches support it, create a port-channel, aggregate all four ports together and trunk/vlan-tag the connection as a whole. Best of both plus resilient to port failure!

 

Kudos appreciated, but I'm not hunting! (ACMX 104)

Switch should support just about anything,  its a HP procurve 5406_zl.    Does the aruba 3400 controller support link aggregation?   Didn't see any options for it.

Yes.  Please search the user guide for link aggregation.
