During the debugging of T247561 the hosts kafka-jumbo1006 and stat1005 were moved to different switch ports that didn't really work.
- stat1005 on ge-1/0/4 and kafka-jumbo1006 on ge-1/0/5 show up in icinga at the same time as DOWN
- kafka-jumbo1006 is moved to ge-1/0/9 and regain connectivity
- stat1005 is moved to ge-1/0/6 but still shows no connectivity
- stat1005 is moved to ge-1/0/43 and regain connectivity
So at least 3 ports on asw2-d-eqiad are not working as expected: ge-1/0/4, ge-1/0/5 and ge-1/0/6
Arzhel suggested to test those ports with a laptop or similar to see if they are really not working at all or not.
