[AusNOG] Dark Fibre going Error Disable

[Skeeve Stevens]

Hey Nathan,

Logs are minimal.

May 14 16:58:25.672 AEST: %LINEPROTO-5-UPDOWN: Line protocol on Interface
TenGigabitEthernet3/1/2, changed state to down
May 14 16:58:30.470 AEST: %LINEPROTO-5-UPDOWN: Line protocol on Interface
TenGigabitEthernet3/1/2, changed state to up
May 14 17:00:22.888 AEST: %LINEPROTO-5-UPDOWN: Line protocol on Interface
TenGigabitEthernet3/1/2, changed state to down
May 14 17:00:23.886 AEST: %LINK-3-UPDOWN: Interface
TenGigabitEthernet3/1/2, changed state to down
May 14 17:00:25.194 AEST: %PM-4-ERR_DISABLE: link-flap error detected on
Te3/1/2, putting Te3/1/2 in err-disable state (RKN03L06SWCORE02-3)

Seems to be nothing else on either side... which is why I am asking... very
odd for Dark Fibre.
