this is my first question over here.
I have a question about using
channel-group mode on or
channel-group mode active.
I have a core 3750x with 2 stacked SFPs nodes. Each pair of ports of a node with the same port number is an etherchannel:
- Gi1/0/1 + Gi2/0/1 = Po1
- Gi1/0/2 + Gi2/0/2 = Po2
- and so on
These etherchannel connects to the 2960 switches, where they have a SFP module, using 2 SFPs ports to connect to the 3750x. Those two ports are also an etherchannel.
All the Po's interfaces are in
channel-group mode on on both sides.
The Po interfaces are ok, all UP and not giving me errors.
But I'd like to know:
- Is this a good pratice?
- Is it better to use LACP? Why?
- Any of you guys ever had any problem using mode on?
Thank you very much!
Obs.: I read the article Preventing STP loops in etherchannels configurations
But in my case I know and I manage both sides of the connection
