Bridge-Aggregation between hp 5700 and dell 3048

hello

I want to set a bagg between the 2 switches 
The challenge: The link is over a network of fiber optic providers  ( wdm network )  
I don't always see the link fall down at the level of port  in the switch

 

best regard

Hi, it looks like you already did a LAG setup between those switches...but the way you did caused you some issues, issues you're trying to overcome.

The point is that you're forcing a deployment in the wrong way...violating typical requirements valid for LAG setup:

Each physical link's port (on bot ends) that will become a member of a Link Aggregation Group must (along with other member links):

 

  1. be in full duplex mode
  2. use the same data transmission rates
  3. use point-to-point connections AKA no Switch or other devices in between peers
  4. be co-terminus (it starts on a Switch and it shall end on the very same peer one, physical or logical)

So you're basically violating the point 3 so your LAG will have unpredictable behaviour (exactly as you are experiencing right now).
