Issue

  • Network ports are physically linkup but "All Path Down" occurs on ifgrp:a0a(e0a,e0b,e0c,e0e).
  • Link down/up events are reported repeatedly on switch side which is connected to e0a & e0b port.
  • Ifgrp a0a is working fine with e0c & e0e port when the cables are pulled out from e0a & e0b port.
