HI everyone our two 6509 configured VSS , standby box SUP crashed at mid night and not came back online itself,remain in ROMMON. we found at same time , one upstream switch has two interfaces connect to this two box seperatly, this two interfaces were down at same time. all communication through VSS had been down for almost 8 hours until we found problem on morning and reboot standby box, now it is ok but in this failure, standby box crashed , active box lost vsl and dual-detect link , this was not dual-active , why upstream switch two interfaces were all down. I think during standby box sup crashed. in this short moment,TWO BOXES WERE NOT STABLE , active box DUAL-DETECT MECHANISM had some LITTLE opportunity or time to detect dual-active, and shutdown it's interface.and BUT unforturnately standby box hadn't come back and remained in ROMMON. so upstream switch two interfaces were all down
if I am correct, this is ridiculous, because i can't avoid this kind of standby box sup crash failure . does one active box in VSS don't has ability to come back from this failure automatically. how can I config to made old-active box interface come back if standby box go into ROMMON status for a long time. THANK you! Tom
