Layer 2 Uplink

[knaik99]

if switch is going to core as fiber from one uplink and copper from another uplink then this design will work or not?

is it proper practice to do that

Hello,

only if you want to combine the interfaces into a port channel, they need to be both of the same type. What do you want to accomplish ?

What is the use case here, due to ports fully used ? why not use both fibre or copper ?

[Leo Laohoo]

Will it work? Yes.
Is it recommended? No way.
Why? Because copper link break easier than fibre optic.

As a number of people have mentioned.  Yes.  This will work.  We are likely just very confused.  Usually when you have parallel links between two boxes they can both transmit (Tx) and receive (Rx).  Would love to help better answer your question.  Do you have a picture or a little more on what you are trying to accomplish bigger picture wise?

Are you talking about the amount of members in the channel? You can use any amount from one to the max supported. But using an amount of members that equal to the power of 2 (2,4,8,(16)) gives you the best load distribution on the channel-members.
