Problem: eTrack 1534270 (LLT : Low pri link goes in trouble due to one-way-link detection code; provide a seperate tunable for trouble on lopri links).


Prior to SF HA 5.1, customer needs to increase the peertrouble setting in lltconfig for these messages to cease.  

Solution:

lltconfig -T peertrouble:400
 

 

Since SF HA 5.1, a separate peertroublelo tunable has been added for low priority links. So, in order to modify the peertrouble value for low priority links, we can do as follows:

lltconfig – T peertroublelo:
