I got Multiple 4600 switch connected to 4600 Stack Switch.
Let's name the 4600 stack switch - physical switch X and physical switch Y respectively.
I have 4600 switch A connected to both switch X and switch Y.
I also have 4600 switch B connected to both switch X and switch Y.
How do I configure switch A go to switch X as master, switch Y as slave?
AND
How do I configure switch B go to switch Y as master, switch X as slave?
I want to load balance the traffic.
Thank you.

Hi @businessuer,
Once the switch become a master, it can't be a slave at the same time.
And you may consider the stacking switches as one switch which has more ports.
So, technically, you can't set load balance to switch X or switch Y since these switches has become one switch after stacking.

Ok。So what is your suggestion to solve the problem?
I want for example odd ports to use switch X as master switch y as slave.
Even ports to use switch Y as master switch X as slave.
Can you give me some suggestions on how to change design?

Hi @businessuer,
May I know why you want odd ports to use switch X as master and Even ports to use switch Y as master?
In addition, is this topology as same as your original purpose? If not, please correct me.

No no.
Switch B has 1 link to Switch X, 1 link to switch Y with lacp configured.
Switch A has 1 link to Switch X, 1 link to switch Y with lacp configured.
Switch X and Switch Y are stacked together, 2 physical as 1 logical.
I want switch A to forward traffic to switch X as active, switch Y as standby.
I want switch B to forward traffic to switch Y as active, switch X as standby.
Can this be done?0 -
@businessuer - I think you can accomplish what you want by implementing Spanning Tree Protocol and removing the LAG.
Just out of curiosity why do you want a master slave arrangement rather than letting the stacked switches and lacp manage the traffic?0 -
From the fault-tolerant design point of view.
That's make sense to separate different group workload to different module.
After check the user guide and CLI guide of 4600 switch.
Cannot find how to configure the lacp port-priority, which is common used in Cisco/HPE/Aruba even TP-link switch.
Look like 4600 switch support lacp system priority setting but not lacp port-priority setting.

Hi @businessuer,
Just like @imaohw said, you may use STP to accomplish what you want.
Here is the setting I suggest:
The RSTP setting on stacking switch:
Enable RSTP and change the port priority which you want switch forward traffic first to 1. (For example: The port that switch X connect to switch A should set port priority to 1, the port that switch Y connect to switch B should set port priority to 1.)
This makes switch A to forward traffic to switch X as active, switch Y as standby and switch B to forward traffic to switch Y as active, switch X as standby.
The RSTP setting on switch A&B:
Enable RSTP and not need to change port priority since we set on stacking switch.
Notice: Please disable lacp since lacp will make RSTP recognize there is only one link but not two links and won't block the link which we would like it become backup link.

Hi Zyxel,
So if I use rstp, it will be active-standby based on my port requirements.
In that case, what is the advantage if I use lacp on the 2 physical switches.
Will be it be active-active?
Will the bandwidth usuage be actively distributed between Switch X and switch Y then?0 -
Hi @businessuer,
The advantage is that lacp can increase network stability and load sharing the traffic to increase bandwidth usage.
If you use lacp on the 2 physical switches, it will be active-active.
Switch will hash the traffic depend on the criteria you set to send traffic to Switch X or Switch Y to increase bandwidth usage.0 -
Ok in that case lacp works better for me then.
Then I no need choose which port active which port standby.0
