    I have 2 x X670s connected with each other through a 10G x 4 aggregated port. Recently I have noticed that there is flapping of ports of this aggregated link. Any suggestions on why this may happen?

    Hi Danish,

    Port flaps can occur for any number of reasons. The general steps that will rule out common issues is listed in the article below -

    Are the same ports in the LAG flapping always or do all ports in the LAG flap?

    Thanks for your help.

    It started with one port and then all ports started flapping.
