[AusNOG] Dark Fibre going Error Disable

[McDonald Richards]

Normally it's a failing optic at one end. It will probably happen again. Setup the err-disable auto recovery feature so that it comes back after a minute.

Hey Nathan,

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

Skeeve,

There could be a handful of reasons for this such as link flapping, broadcast storm if storm control is enabled on the Cisco end etc.

This is also sent to SYSLOG or shown in the local log if the buffer hasn't filled up as yet.

Hey all,

Just wondering if anyone might know what some triggers would be to cause a dark fibre link to go into Error-Disable.

It was easy to shut; no shut to bring it back online, but it was disturbing nonetheless.

One end is Cisco and the other Juniper using ER optics - not sure if that makes a difference or not.
