Cisco port channel issue

[Ge Qu]

Hi,

We have a port channel with 2 of 1G links between our core of the datacenter.

Due to the issue with one link, we want to force all traffice to another link, only use the 2nd physical link when the 1st physical link is full.

Is there a way of doing it?

We cannot do with src-dst-mac/ip/port etc, those options are not good for us.

Thank you.

Hi,

 Can you play with routing ? If does, i have a suggestion.

It's a Layer 2 link. I cannot play with routing.

What hardware are you running? Different hardware will support different Port Channel Load Balancing options/configuration.

Hi,

Would backup interface solve your requirements based on delay and threshold?
