I have some T1 configurated as PRI (serial X/Y:23) and traps configured for LinkUp LinkkDown.
Some times Im receiving some traps from apparently individual channel example linkUp Serial7/7:21 then after that a linkDown for the same S7/7:21.
1. Why first the linkUP then the link Down?
2. Why from Invidual channel if it link suposed to work on Sx/Y:23?
