Ticket Description: DWDM link Neuch√Ętel-Zurich down

Problem Description:

The Gigabit Ethernet DWDM link between our routers swiNE2 at the University of Neuchatel and swiZH2 at the University of Zurich went down this morning.


From 2009-07-18 02:08:52 until undefined
Impact: no impact
Sites/Services: UNINE

Some routes (between Neuch√Ętel and the Zurich area) have changed, but there is still redundancy for all sites.

Traffic is flowing normally again. The transceiver in Olten (an intermediate node of faulty link) had lost part of its configuration.

We realize that some problems with that link remain. No traffic is flowing though all interfaces are up and no involved modules report any errors.

Problem solved by a cold start of the transceiver module at UniNE.
